Huai'an crane rental Introduce the working principle of the crane, The crane is composed of driving device, working mechanism, taking device, control system and metal structure. By manipulating the control system, the driving device converts the power energy input into mechanical energy, and transmits the force and movement speed to the picking device, which connects the materials to be handled with the crane, and completes the material handling task through the independent or combined movement of the working mechanism. The movable metal structure connects the components into a whole and bears the dead weight and lifting load of the crane.

It is mainly manifested in that there is a rotating drum below the boom, and the steel wire rope is wound above it. The steel wire rope pulls the previous boom out through the pulley on the top of the next boom, and so on. When retracting, the drum reverses to recover the steel wire rope, and the boom retracts under its own weight.

In addition, the telescopic boom of some truck cranes is equipped with a sleeved plunger cylinder, but this application is rare. Because the multi-stage plunger cylinder is expensive, and the boom will bend elastically when loaded, it has a great impact on the life of the cylinder.

Multi action hoisting machinery that can vertically lift and horizontally transport heavy objects within a certain range. It is also called crane. It belongs to material handling machinery. The working feature of the crane is intermittent movement, that is, the corresponding mechanism of reclaiming, migration, unloading and other actions in a working cycle works alternately.

Huai'an equipment displacement Pay attention to the following issues:

1. Each crane must be hung with a label of rated lifting capacity at a conspicuous place.

2. During work, no one is allowed to be on the bridge or use the hook to transport people.

3. It is not allowed to drive a crane without an operation permit or after drinking.

4. During the operation, the operator must concentrate, do not talk, smoke or do irrelevant things.

5. The vehicle shall be clean; It is not allowed to place equipment, tools, inflammables, explosives and dangerous goods.

6. Overload of crane is not allowed.

7. Lifting is not allowed under the following conditions: loose binding; Overload of parts; Unclear signal; Cable-stayed; Objects buried or frozen in the ground; Someone is on the lifted object; Inflammables, explosives and dangerous goods without safety protection measures; Overfilled liquid articles; The wire rope does not meet the requirements for safe use; The lifting mechanism is faulty.

8. When the crane is running on the line without obstacles, the hook or lifting appliance and the bottom of the lifting object must be 2m above the ground. If you cross an obstacle, it must be 0.5m higher than the obstacle.
