Crane Hydraulic System Attention five-point problem

At present, China is basically a hydraulic  overhead bridge crane  as their motivation to work, so there are many internal parts of the crane hydraulics. The normal operation of the hydraulic unit is the basic crane working key. Therefore, if there is no operation and maintenance in accordance with prescribed rules, on the one hand, causing the crane does not work properly run. On the other hand, may also greatly reduce engine life. Therefore, in our daily work operations, you should look at five questions:
First, we work, we must first check the mailbox crane hydraulic oil is not adequate, if not enough, it should be added immediately. In addition, the refueling time, we must proceed from a strainer to join, but can not add other brands of hydraulic oil;
Second, the oil filter cartridge job almost ten days or so, it shall be checked, if necessary to carry out cleaning and replacement;
Third, the hydraulic tank fifteen days will put out the oil from below and remove impurities. In addition, when the  overhead gantry crane  work for a year, I want to replace all the hydraulic oil tank.
Fourth, there are many crane hydraulics valve is not the same as they had before the manufacturing factory after various experiments tune just the flow and pressure when in operation do not easily rotated, so as to avoid the machine failure.
Fifth, after each job, remember to clean the hydraulic unit.
steel cranes need our routine maintenance when the job should comply professional charters to avoid some of the accidents.
