The crane legs are very important during the crane operation. In addition to supporting the crane according to the surrounding environment to avoid risks, some unnecessary faults of the crane legs should be eliminated in time: the crane legs cannot be opened normally. How to solve the problem that the crane legs cannot be opened normally? Many machines need to be supported by outriggers during operation to prevent rollover and other safety accidents. If it is found that the outriggers of the crane cannot be opened normally, Huai'an Crane Leasing Company Xinyu's small editor tells you how to solve it!

The outrigger of the machine is abnormal, which has many manifestations. If people want to solve it effectively, they need to understand its causes first, and then they can deal with the symptoms. Therefore, the personnel are required to pay attention to accumulating experience in the continuous operation process, and do a good job in the inspection and maintenance of components at ordinary times, so as to find abnormalities as soon as possible, avoid major failures, and improve the efficiency of the overall construction.

In the actual operation process, the common abnormalities of the crane are, such as the sinking of a vertical oil cylinder of an outrigger, which can be eliminated by exchanging with any other trouble free two-way hydraulic lock of the vertical outrigger, but it should be noted that before the exchange operation, the piston rod of the corresponding vertical outrigger oil cylinder should be extended, The foot plate of the vertical outrigger is about to contact the ground and is not stressed.

Another situation is that one leg rebounds and floats after it is not stressed. This fault is mostly caused by the failure of the vertical outrigger oil cylinder, which is mainly caused by the internal leakage of the oil cylinder piston and needs to be disassembled and replaced with a seal. In addition, if multiple outrigger vertical oil cylinders sink, personnel should first check whether the outrigger system pressure is within the safe value. If yes, the lower control valve group needs to be replaced, if not, the personnel need to standardize their own operation.
