4k Cameras for Video Production


Film makers whether professional or amateur, know the importance of a good camera in video production. When the quality of the picture is everything in your production, shoot with a 4K camera. 4K earns its name due to its approximately 4000 pixels in its horizontal resolution. All 4K camera come with an LCD screen placed at the back so as to enable you to see action as it is being recorded and also to get immediate feedback on your work.

These lightweight and compact cameras are mountable, durable and compatible with various lenses and most of them have built in WI-FI capabilities. For additional protection especially in rugged shoots, some of them are coated with rubber.

External recorder

Most 4ks are require external recorder as they are unable to record internally .This makes the cost of the camera less but you have to factor into your budget the cost of the external recorder. One big advantage of using the external recorder is that you can rent them. If you are not often shooting in 4k, you can save a lot of money overall.

4K codec or formats

It’s known that 4K is just a resolution. There is no agreed upon standard of how the resolution should be stored making the storage different in many cameras. The different recording format leads to drastically different workflows calling for care when purchasing a camera. It’s therefore important to make sure that you use a recorder or a camera that records 4K in a manner that works best for you. Some 4K cameras have the capability to record in RAW and 4K video codec while others can only record in 4K video codec.

Frame rate

HD videos frame rate is usually standardized for TV at 60i. This is opposed to 4k as they have no broadcast standard therefore you should not assume anything with regard to the frame rates of the camera. Some 4Ks cannot shoot slower than 60P while others can shoot faster. Cameras that shoot as 30P are best if the content will be downscaled to HD for TV distribution since that will convert to 60i easily.


Dci or QHD

Some 4K cameras have both Dci and UHD shooting while others can shoot only one type. All Hd content of most 4Ks is shot in the aspect ratio of 16:9 with the most common being the digital camera initiative (DCi) that defines 4K as 4096 x 2160 at 17:9 aspect ratio. The other format is the ultra high definition that is 3840 x 2160 at 16:9 aspect ratio.

Benefits of using 4K cameras

  • Higher resolution
  • High quality
  • Detailed images
  • Larger visibility on projection surface



Why Construction Crane Tractor Insurance Is Important in Construction Projects

Skyscrapers define much of what modern civilization has to offer. Only on rare occasions do we see all of the skyscrapers in the city, and rarely do we question how such very high buildings came to be. One can say that they were constructed. But do you know that such construction would not be possible without a construction crane tractor?

Why Construction Crane Tractor Insurance Is Important in Construction Projects

A crane is described as a machine that’s basically trapped with winder or wire rope drum, sheaves, and wire ropes that are utilized for lifting, lowering, and moving materials horizontally. Thus, a crane can be considered as a lifting and lowering machine. Whenever you think about construction these days, it is almost impossible not to think about having a crane to do the heavy lifting. But working with a machine that’s hundreds of tons heavy can be quite a challenging and risky thing.

Cranes are expensive because they are made of very sturdy materials. Making a crane takes time and money, and a crane that becomes destroyed during construction would be costly. It is thus important to have crane insurance to safeguard your business and personnel. Crane insurance can cover not only the machine but also the operators of the machine.

Why Construction Crane Tractor Insurance Is Important in Construction Projects

Crane insurance is necessary not only for construction projects but for the general public as well. Such insurance maintains the constant use of these cranes from the builders. Modern construction thus finds it mandatory to have crane insurance every time a crane is used. It is thus an inseparable part of construction projects with a working budget and deadline.

Construction is a challenging field that requires skill, courage, strength, and determination. Stress can be easily alleviated through the crane’s insurance policy and also for the sake of the personnel and the equipment.

Various Construction Crane Gears That You Need to Know

Working in a construction site is also working with heavy machineries. Some of these huge machineries are construction cranes. Crane is one of the most useful construction machines utilized for lifting heavy items to the skies and putting them in their directed destination. All jobs are done via lifting force.

The major parts of construction cranes are sheaves, hoist, wire, or chains and ropes, and all these parts are essential, merged together to complete any given task. You may ask, what are the basic parts of cranes? To know some of the vital crane gears, we will get to know each one of them.

Various Construction Crane Gears That You Need to Know

Wheels – wheels of various sizes that can fit any crane are important. A crane without wheels is useless. You can purchase these from the market, and you can also buy a customized design.

Gears – these can be fitted with any brands of cranes to have a smooth work operation. However, you have to make sure that these are robust and long lasting.

Motors – a crane is made to lift heavy items, and it weighs about a ton. For these reasons, it requires powerful motors to carry out its job. Thus, it’s a must to opt for a durable and powerful crane that has the capacity to carry a considerable weight.

Various Construction Crane Gears That You Need to Know

Controls – safe and efficient crane controls are utilized in any crane operations. These controls measure accurately the crane’s performance and notify the workers or operators of any possible issues in the operation. Thus, these allow them to do proper measure to prevent any mishaps from arising. These single- or two-speed controls are widely available in the market.

Bottom blocks – these blocks are placed at the bottom of the crane in lifting heavy materials. It’s better to opt for the 360 crane block as it makes shifting and lifting of heavy objects more convenient and easier. Bottom block comes in wide varieties. Make sure you opt for one that is made from top-grade steel since it is durable and has a corrosion-resistant surface.

Drive shaft – a shaft for the crane’s motor ensures accurate bearing fit, keeping its strength and integrity, making the functioning of your crane sound and smooth. This can be obtained from hardwares and other auto and motor supply shops in your place.

Gearboxes – as one power source fails, gearboxes intervene. Make sure you settle with the gearboxes that are identical to the original.

These are just some of the gears and parts that make a construction gear function efficiently. Each of them works hand in hand to ensure that the crane works as it should and carries the job well.

Types of Electric Construction Cranes

Cranes are one of the equipment used in construction projects that are electrically powered. It is so tall and huge that it is pretty difficult to miss when you are near or on a construction site. They are particularly used for the construction of large buildings where lifting and placing heavy materials are needed. In high rise buildings, these cranes can go through elevator shafts. There are several types of construction cranes that are being used depending on its function and advantages.

Types of Electrically Powered Construction Cranes

  • Hammerhead Crane

Hammerhead crane is commonly associated with a tower crane. There is usually a horizontal jib attached to a vertical tower wherein one end of the horizontal jib extends to the work area, while the other end is used for counterweight. There is also a trolley that holds the lifting cable which can travel along the length of the jib. The tower crane can operate within the radius of the jib. This type of crane actually requires a second crane intended to assemble and dissemble them in the work area.

  • Self-Erecting Tower Cranes

Self-erecting tower cranes, as the name suggests, can actually assemble itself in the construction area; thus, it eliminates the need for second cranes which makes it cost- and time-efficient. While some types of cranes require operator cabs, this type of crane can actually be controlled remotely from the ground. Aside from that, it is free-standing and can be moved around the work area.

  • Luffing Jib Tower Crane

The luffing jib tower cranes are usually used in tight urban work areas. Crane operators with this type of crane can raise or lower them to swing in a reduced radius. Unlike other cranes, luffing jibs do not make use of a trolley; they only raise or lower the jib if they need to lift materials closer to the tower.

Types of Electric Construction Cranes

Types of Construction Crane and Its Uses

Big buildings and houses are constructed and erected with the use of different equipment. We often see from movies how massive buildings are built through the use of machines that is called crane. Cranes are generally fitted out with chains or wire ropes, sheaves and pulley where it can be used to lower and lift heavy materials and transport them to other places without the hazard of disturbing other constructed area. Construction cranes are important in the construction industry because they are fitted in working heavy machinery that makes construction easy.

Types of Construction Crane and Its Uses

Almost everything in construction uses cranes. They are valuable in every construction industry where it can handle massive loads of materials beyond the capacity of the strength of individual. Below are some interesting examples of different cranes and its uses:

Types of Construction Crane and Its Uses
  • Aerial cranes – these cranes are sometimes called sky cranes as it is basically a helicopter used exclusively for heavy lifting of materials where conventional crane does not work. This crane is also helpful in disaster relief operation and risk relief programs. It is also used in high rise building lifting heavy loads and sometimes used to carry huge buckets of water to quench wild fire.
  • Vehicle mounted cranes – cranes are used in construction as temporary structures, some cranes are mounted into vehicle so that they can be moved easily when the construction is done without the hassle of dismounting it. Generally, this crane is able to travel on the road and removing the need for extraordinary equipment to transport the crane. However, if the crane is large, special equipment is needed or some trailers are used to carry heavy cranes. Vehicle cranes come in different forms and this includes side lift, rough terrain, pick and carry, carry deck, telescopic handler and crawler cranes.
  • Floating crane – this crane is purposely used in building bridges and construction of port. Some floating cranes are used for loading and unloading on, especially heavy loads on or off ships. There are also cranes that are mounted in platform and others are crane barges which can lift the entire bridge sections.
  • Tower crane – this type of crane is also called a fixed crane. Tower crane is used in construction of tall buildings and it is fixed to the ground during the period of construction. It also mounted on a strong concrete pad in order to have the ability to lift and carry more loads.

There are also other types of crane that is useful in other manufacturing plants that move along beams which support in lifting massive products and materials. All types of cranes are important and it should be handled properly.

The Installation of Air Safety Flags in Construction Cranes

Construction cranes are considered to be air safety hazards. This is primarily because they actually extend up to more than 200 feet; which is why the Federal Aviation Agency (FAA) requires crane owners to hang warning flags on the boom. These warning flags are usually checkered with colors orange and white, and measure about 3×3 feet. A type of warning flag, called barricade flags, which are used to mark hazardous areas are usually solid orange in color.

The Installation of Air Safety Flags in Construction Cranes

How to Install Air Safety Flags

  • Take note of the height in which your crane boom will be raised or extended. According to the regulations of the FAA, air safety flags should be placed when crane books are raised more than 200 feet above the ground.
  • For every 50 feet that the crane boom is being raised, provide at least one orange & white checkered air safety flag which measures at least 3×3 feet. It is important to note that heavy flags should be used in order to prevent them from being obscured from view.
  • Slide the flag’s grommet to the crane boom’s built-in hook. Make sure that you have properly pushed the grommet to the hook to prevent any accidents such as slipping off.
  • Install air safety flags for every 50 feet along the crane boom. Orange and white safety flags should be placed every 30 feet along it in the event that there are two or more cranes in the construction area. Ensure that the flags are clear from the moving parts of the crane boom.
  • Solid orange safety flags should be placed on the crane below its boom. Print the words “Boom Raised” in one of these flags.
  • It is very important that you attach a hook to each of the grommet of the orange flags and attach them to the hooks on the crane. Ensure that they are visible in all angles on the ground.
  • Warning signs and flags should also be installed around the crane and the entire work area to caution vehicles and pedestrians.

The Benefits of Using Mobile Construction Cranes

In any city’s development, mobile cranes play an important role ever since then. Though this isn’t as powerful as other industrial cranes, mobile cranes are way flexible and easy to use. It pays for you to be aware that this is not the most powerful cranes around, but you would certainly be shocked with the kind of regularity in which people favor to discuss about these cranes. Such machines are considered to decrease the time required in hauling stuff over distances.

Mobile cranes are most efficient in reaching critical areas and parts of large buildings. They are effective in giving solution to emergencies and for getting access to areas that are near factory and construction sites. To show you more of the benefits of using mobile cranes, here is a list of a few ones.

The Benefits of Using Mobile Construction Cranes

They reduce assembling space in construction settings

As we normally notice, construction setups consume a huge amount of space, and this is mainly because of the space eaten by cranes and other essential equipment and tools. Before, static cranes were utilized in construction project, but it has changed now since mobile cranes are readily available, giving solution to your space issue.

The Benefits of Using Mobile Construction Cranes

They decrease the cycle time period of construction projects

Assembling these mobile cranes can be done in just a jiffy. Thus, this permits construction contractors to get things done in a fast and cost-efficient manner. Essentially, getting these cranes to construction areas wouldn’t be a hassle. You no longer have to close the road or hinder vehicular traffic, which could be the case with other kinds of cranes.

The Benefits of Using Mobile Construction Cranes

They boost hoisting power

Due to the presence of multiple turning axles, mobile cranes can have the capacity to hoist greater weights. Actually, it’s more than the average lifting power of a tower crane.

Evidently, the use of mobile cranes in the construction world has its own set of merits. Well, construction firms obviously love the fact of having a crane that is easily movable and can complete the project speedily, and mobile cranes made all of these possible.

Setting Up the Construction Crane

Tower cranes can be pretty hard to set up primarily because you need to be able to balance it so that it won’t fall; geometric vectors need to be applied. This construction equipment does not arrive on the construction site completely assembled; they usually arrive on 10-12 tractor-trailer rigs. The crane jibs and other machineries are usually assembled by another mobile crane to place them horizontally on a 12-meter mast. This mobile crane installs the counterweights as well.

Setting Up the Construction Crane

In order for the mast to rise, it needs to have a firm foundation. The mast is actually large in size and has a triangulated structure which is typically 3.2 meters square in area. This structure helps the mast to remain upright while the crane is at work.

Setting Up the Construction Crane

How Does the Crane Grow?

In order for the crane to rise to its maximum height, it needs to grow itself one mast section at a time. Thus, construction crew makes use of a climbing frame that fits in between the top portion of the mast and the slewing unit. The process of growing the crane is as follows:

Setting Up the Construction Crane
  • It is very important to note that in order to balance the counterweight of the crane the construction crew has to be able to hang a weight on the other side of the jib.
  • Then, the construction crew has to detach the slewing unit from the top portion of the crane’s mast. They make use of a large hydraulic ram to push the slewing unit up to 6 meters.
  • Lastly, the operator will then make use of the crane in order to lift a 20-foot mast section and place it into the gap that is opened by the climbing frame. As soon as the bolts are in their proper place, the crane will be 20 feet taller. The process then goes on and on until the crane reaches its maximum height.

Residential Construction Crane: How it Works

Whether it is residential, commercial or industrial, each project needs to have the right and appropriate equipment to ensure safety and achieve success. Many of our buildings now are using heavy materials that need to be lifted up with the help of particular equipment such as the crane. Some residential projects are using heavy metals and materials where cranes are needed to do the job with ease. The most common crane used to residential buildings is the self-erecting tower crane. This type of crane is very easy to handle in constructing residential buildings. It can be assembled and mounted easily and most of this type uses electricity instead of fuel. Using residential construction crane will give you enormous benefits and can save you lots of money and time. Below are benefits you can get using the residential construction crane.

Residential Construction Crane: How it Works
  • Improved productivity, efficiency and increase carpenters’ drive and leave them greatly fresher at the end of the long day.
  • Single-person manoeuvre on multiple tasks instead of having many people in doing lifting and setting rafters and trusses.
  • The right materials can be handled and delivered one time without moving them multiple times to give way for mobile equipment.
  • Construction components are efficiently assembled such as wall sections, roof, built-up beams, etc.
  • It reduces and eliminates various pieces handling equipment to be used in jobsite such as telehandlers, boom trucks, mobile cranes, etc.
  • Reduced the fuel cost and does not disturb surrounding terrain.
  • Increased utilization of resources as well as it is accurate and fast in terms of placing the materials that are needed.
  • Less expensive and easy to operate with the use of remote control operation or a single-person operation.
  • Lesser site setting up costs and reduction in noise and pollution.
Residential Construction Crane: How it Works

The advancement of technology makes the job fast and efficient where the use of residential construction crane is one of the best proofs of how technology helps people become more productive.

Renting Construction Cranes

In any construction project, cranes are of great use. Efficient cranes are designed for carrying heavy loads and objects. Most industries that need to deal with heavy load depend on the cranes’ services to carry the job smoothly and easily. Purchasing a crane from your own pocket can be costly, though. Managing a construction firm is not easy as one has to face some incidental expenses. One has to do a cost analysis of buying versus owning such machinery. What most construction companies do in this case is rent the service from crane companies.

Renting Construction Cranes

Renting construction cranes is way practical because the cost of buying and maintaining a crane, compared to the amount of its usage, doesn’t warrant getting a crane. Instead, most people ask the assistance of professionals from the crane industry to supply them their quality and specialized machines with operators to host materials for a certain project.

Renting from a crane firm ensures that the right tools, safety records, and operating procedures are used throughout the process. However, a project manager should consider some important things to end up with the right company. First, assess how long the firm has been in the business. With this, you will know the experience and how successful a company is at providing high-quality service. Second, the safety level of the crane company should be considered. Does it prioritize safety first? This is very important to assess since working in a construction site is risky, and workers become prone to injury. Last, inquire about the kind of equipment mix the company has, whether it has the right blend of cranes. So if there are problems or if mechanical failures arise, replacement can be directly sent to finish the job.

Renting Construction Cranes

Remember that when it comes to using cranes, it’s better to be safe than sorry. Thus, it is important to opt for the right renting company to ensure security of work and workers.
