Hoisting equipment is mostly used in construction industries where there is constant lifting and shifting of loads and crane rigging is involved. Hoists are designed to lift objects from the ground, against gravity and shift them to a reasonable distance. Considering their importance, let’s discuss the different types and their roles in the construction industry.

Hoist is a term used to lift a load or weight, just as a forklift or a crane would do. For instance, you can hoist yourself up onto the roof to get a better view of your neighborhood. However, the term is usually used to describe lifting heavy materials in different industries.

These hoists serve different purposes and are made to lift and shift extremely heavy loads. Without them, a crane will not be able to carry out its task of loading and unloading weights.

Types Of Hoisting Equipment

Moveable Pulley

A pulley is a wheel on a shaft or an axle that is designed to change the direction of the belt or cable along its circumference. Pulleys are used for a variety of reasons such as applying forces, lifting loads, and transmitting power.

Additionally, a pulley may also be called a drum or sheave and might also have a groove between the two flanges around its circumference. The element driving the pulley might be a cable, belt or rope, etc.

Rope And Pulley

The pulley and sheave blocks are designed to lift rough surfaces and heavy loads. For this, constructors usually use wire ropes and chains. Therefore, alloy chains are the most preferred option. However, the load hook tends to be the weakest component of the system. The hook needs to be replaced and is of no use if straightened.

Chain Hoist

Chain hoists tend to be a popular mechanism designed for lifting loads in tones. The system consists of two sets of chains, commonly known as hand and load chains. For the isolated locations, hand chains are used, where electric motors or other types of mechanical equipment are not available.

The load hook holds the load that needs to be lifted, while another hook supports the mechanism, at the top. However, the two hooks should not be interchanged as the support hook is designed to be stronger.

Tower Crane

Tower cranes are a popular occurrence at construction sites, usually identified by their high steel towers. These cranes are usually mounted and are designed to lift weight at extreme heights for working on high-rise buildings. The best thing about these cranes is that they can easily work in congested areas.

Furthermore, these cranes are also a combination of stationary and mobile units. As a result, you get the mobility of a mobile crane and the advantages of a log boom of derrick crane. These cranes are not only powerful but also get the job done within the shortest span of time.

Overhead Gantry Crane

The overhead or gantry cranes are indispensable machines that are mostly found in workshops and factories. In large workshops, these cranes are used separately for fabrications or repairs of machine parts. Therefore, the parts that need to be repaired or replaced can easily be shifted using Gantry cranes.

Air Powered Hoist

Air-powered hoists are a special type that is designed to rapidly lift weights. These hoists offer impressive speed and are designed to be used constantly. Since these hoists are powered by compressed air feed, they are a great alternative to electric hoists, where there are no power sources available.

The biggest advantage of using air-powered hoists is that they have no limitation when it comes to using them. While electric power hosts can be used for a maximum of 15-minutes in a one-hour period, the air-powered hosts can be used constantly.

Scaffold Hoists

Scaffold hoists are designed to assist scaffolding work. They can be easily fitted to the scaffolding directly, making it a lot easier to transport loads between and up and down the ground and work platforms respectively.

Final Word

Concluding, hoists are used for and by several different industries. They have a crucial role to play when it comes to loading, unloading, and moving heavy weights. When it comes to picking the right hoist, make sure that your needs and preferences are in line with the task that needs to be carried out. Consult with rigging companies MD to have the right tools for the job.
