What are the lifting equipment?

1, heavy equipment can be divided into light and small lifting equipment, elevators, cranes and overhead monorail systems according to different structures.

2. Light and small lifting equipment mainly includes lifting tackle, spreader, jack, manual hoist, electric hoist and common winch, most of which are small in size, light in weight and convenient to use. Except for electric hoists and winches, most of them are driven by manpower, which is suitable for light work occasions.

They can be used alone, and some can also be used as lifting mechanisms of cranes. Some light and small lifting equipment have great lifting capacity, such as hydraulic jack, whose lifting capacity has reached 750 tons. Elevator mainly moves vertically or nearly vertically, and has a fixed lifting route, including elevator, lifting platform, mine hoist and hopper hoist.

3. Crane. Crane is a multi-function lifting equipment that can vertically lift and horizontally carry heavy objects in a certain range. Bridge cranes include bridge cranes, special cranes, gantry cranes, loading and unloading bridges, etc. Boom cranes include truck cranes, tire cranes, crawler cranes, tower cranes, portal cranes, floating cranes and railway cranes.

4. The elevator is a lifting machine that lifts heavy objects or objects along the guide rail, including manned or freight elevator. Although the elevator has only one lifting action, the mechanism is very complicated, especially for manned elevators, which need perfect safety devices and electrical control devices.

Introduction to hoisting:

It refers to the installation and positioning of equipment by crane or lifting mechanism. During overhaul or maintenance, equipment, workpieces, appliances, materials, etc. Be hoisted by various cranes to change their positions.

Hoisting steps:

1. Equipment mobilization, mobilization and hoisting: The mobilization, mobilization, mobilization and hoisting of equipment can only be started after all preparations are completed.

2. Preparation before hoisting: Before hoisting the equipment, comprehensive and detailed inspection and verification must be carried out. Check whether the equipment installation datum mark and azimuth line mark are correct; Check whether the lifting lug of the equipment meets the lifting requirements.

3. The connection of hoisting rigging: mainly including the lifting lug on the pulley, the tension test and direction adjustment of the electric hoist, the setting of the traction and dragging system, etc.

4. Trial hoisting: check and confirm before trial hoisting; The general hoisting commander shall disclose the hoisting operation; The main points and contents of arranging supervision positions; Lift and put it down many times, so that all parts are coordinated and safe; Review the changes of each part, etc.

5. Hoisting in place: the commander-in-chief officially ordered the deputy commander to check the standby situation of each post and check whether the command signal system is normal; Each post reports the preparation situation and informs the podium in time with signals; When the equipment is 500-800 mm away from the temporary support, the equipment shall be officially hoisted and stopped, and further inspection shall be made. Each post should report whether the situation is normal; Remove equipment support and ground sundries, and continue lifting.
