What we need is its flexibility, but many times in the operation process will appear the truck mounted crane action is very slow, causing slow action what are the reasons? Here's CNS to find out.
What we need is its flexibility, but many times in the operation process will appear the truck mounted crane action is very slow, causing slow action what are the reasons? Here's CNS to find out.
The reasons for the slow movement of the crane: 1. Check whether the working pressure of the hydraulic pump is not enough. The deterioration of the gear oil, the embrittlement of the hydraulic pump or the rolling of the clutch will cause insufficient working pressure. 2. Check whether the pressure regulator is wrong or not leaking. The new motor control lifting equipment must also check whether the working voltage of the servo motor is controlled, and whether the control rocker has common faults. 3. Check whether the hydraulic actuator (hydraulic system, oil motor) has common faults (skeleton seal leakage, motor embrittlement).
It can be analyzed from two aspects: oil passage blockage or insufficient power of car engine: According to the matching of the truck chassis and the crane, the driving force of the hydraulic transmission system of the truck crane comes from the car engine, generally 8 tons of truck crane is usually equipped with 180 horsepower car engine, if it is equipped with 140 horsepower or 160 horsepower car engine, when the net weight of the lifting is 8 tons, the action will be slow; When the horsepower of the automobile engine is 180 horsepower and above, then it can remove the insufficient horsepower of the automobile engine, according to the service life of the crane, because the long-term application of the gear oil will cause residue, blocking the oil passage resulting in slow action of the crane, it is necessary to remove the gear oil on time, and clean the filter and hydraulic oil filter.
The crane can adjust the accelerator pedal if it turns slowly. In fact, you can check: 1, check whether your gasoline pump has gas or abnormal speed ratio, it is likely that the pump has a small problem, 2, check the gate valve of the oil channel, it is likely that the speed control valve credit card, so the working pressure will not be created!
The above is the "reasons and solutions for slow action of truck crane" brought by CNS. I hope it can help you. Mainly from the pressure, control valve, throttle and other places to check, if not, you can find a professional department maintenance.
