Safety setting of Truck Crane

In order to ensure the safety and reliability of lifting operations, the Truck Crane are equipped with more perfect safety devices, so that they can play a protective role in accidents, or remind operators to pay attention to them.

1. the overflow valves in the hydraulic system: the abnormal high pressure in the loop can be suppressed to prevent the damage of the hydraulic oil pump and motor and prevent the overload.

2. boom luffing safety device: when the accident occurred, hanging high pressure hose or tubing arm hydraulic cylinder in the loop burst or off when the balance valve in the hydraulic circuit play a role, from the locking cavity of a cylinder oil, the boom will not fall, so as to ensure the safety of operation.

3. scalable security device: when the accident occurred, hanging high pressure hose or tubing arm telescopic cylinder in the loop burst or off when the balance valve in the hydraulic circuit play a role, from the locking cavity of a cylinder oil, so that the hanging will retract, so as to ensure the safety of operation.

4. height limit device: after lifting the hook to the required height, it will touch the limit weight and open the stroke switch, and the "crossing" indicator light will be bright. At the same time, it will cut off the operation of lifting hook, boom extension and boom and so on, so as to ensure safety. As long as the manipulation hook drop arm retracted or boom up (to the safe operation etc.) handle, so the limiting weight lifting operation is restored to normal constraints. On special occasions, if we still need to make trace over operation, we can press the release button on the instrument box, then the function of the limit will be relieved, but at this time, the operation must be very careful and careful, so as to prevent accidents.

The 5. leg locking device: when the accident occurred, leading to the vertical leg cylinder high-pressure hose or pipe burst and cutting, the hydraulic system of two-way hydraulic lock can be sealed off the legs of the oil pressure cylinder two chamber, made a leg up or out, so as to ensure the safety of lifting operation.

The 6. weight indicator: the weight indicator is set on the side side of the basic arm (that is, the right side of the control room). If the operator sits in the control room, it can clearly observe that it can accurately indicate the elevation angle of the boom and the rated lifting capacity of the Truck Crane under the corresponding working conditions.

The 7. lifting characteristic table is set on the front side wall panel of the control room. The table lists all kinds of arm length and rated lifting and lifting height under various working ranges, so that it can be consulted during operation. When lifting work, it must not exceed the value specified in the table. In order to ensure the safety and reliability of lifting operations, the Truck Crane are equipped with more perfect safety devices, so that they can play a protective role in accidents, or remind operators to pay attention to them.
