Crane rental What are the indispensable safety devices during construction? Huai'an equipment displacement The company tells you.

1. Each overflow valve in the crane hydraulic system

It can suppress the abnormal high pressure in the circuit to prevent the damage of the hydraulic oil pump and motor and prevent them from being overloaded.

2. Crane boom luffing safety device

When an accident happens and the high-pressure hose or oil pipe in the boom luffing cylinder circuit bursts or is cut off, the balance valve in the hydraulic circuit will work to lock the working oil from the lower chamber of the cylinder, so that the boom will not fall, thus ensuring the safety of the operation.

3. Telescopic safety device of crane boom

When an accident happens and the high-pressure hose or oil pipe in the boom telescopic cylinder circuit bursts or cuts off, the balance valve in the hydraulic circuit will work to lock the working oil from the lower chamber of the cylinder, so that the crane rental boom retracts itself, thus ensuring the safety of the operation.

4. Crane height limit device

After the hook is lifted to the specified height, touch the limit weight, open the travel switch, and the "over winding" indicator light will be on. At the same time, cut off the hook lifting, boom extension, boom reach and other operations to ensure safety. At this time, as long as the handle such as lowering the hook, retracting the boom or lifting the boom (i.e. operating towards the safety side) is operated, the limit weight will be released and the operation will return to normal. On special occasions, if it is still necessary to conduct a small amount of overwinding operation, press the release button on the instrument box, and the limit function will be relieved at this time, but the operation must be very careful to prevent accidents.

5. Small crane outrigger locking device

When an accident happens and the high-pressure hose or oil pipe leading to the vertical oil cylinder of the outrigger breaks or cuts, the two-way hydraulic lock in the hydraulic system can block the pressure oil in the two cavities of the outrigger and block the oil cylinder, so that the outrigger does not shrink or throw out, thus ensuring the safety of lifting operations.

6. Small crane lifting weight indicator

The lifting indicator is set on the right side of the basic boom (i.e. the right side of the control room), and the operator can clearly observe it when sitting in the control room, which can accurately indicate the perspective of the boom in Beijing Crane rental company And the allowable rated lifting capacity of the crane under corresponding working conditions.

7. Table of crane lifting characteristics

It is set on the lower wall panel at the front side of the control room. The table lists the rated lifting capacity and lifting height under various arm lengths and operating ranges for easy reference during operation. During lifting operation, the value specified in the table must not be exceeded.
