What are the different types of building jacks?

Building jack is used to lift people or materials to different heights along the building or built structure. Some types of building jacks are built exclusively for the transport of materials, while others are built to pull out materials and people. For example, boom cranes can only move materials, while lift jacks can be used to raise workers to a high scaffolding level. Another type of jack uses wheels with a pulley with a cable wrapped around it many times; The hook at the end of the cable is attached to the materials to be raised, and the engine rotates with the pulley to move the cable.

and the boom crane is a vertical column mounted at the top of the building or structure; A horizontal boom is mounted to this vertical column and a pulley is mounted at the end of the boom. The cable is attached to the crane structure and passes through the pulley at the end of the boom. Thekabel mIt can be wrapped around another pulley closer to the vertical column and this pulley can be motorized for cable feed control. At the end of the cable there is a hook or other securing mechanism that can be connected to items to be raised. These building jacks are only used to transport materials and the materials must be associated or otherwise secured to accept the hook. This type of stroke is particularly useful for transporting materials and moving to another location by moving the boom

The electric jack can also be used to lift objects in a similar way to the boom beams, but this type does not use any type of vertical column or boom. It is basically a motorized pulley with a cable wrapped around it many times; The body can be attached or otherwise mounted on a solid structure for stability and the cable can be increased or reduced according to the needs of the operator.

Some types of building jacks are large enough and can be moved stable. These units areFor motorized and travel along the track mounted in sections to a building or structure or to an independent support system. A car of these building jacks will use the stand and the pinion system to move up or down, and the brakes are usually mounted on the vehicle so that they can stop the operator in an emergency. The car itself is usually made of high -degree metal, such as certain types of steel, and will contain gates, rails or other detention systems to prevent users from falling out or preventing or dropping the materials during lifting.
