The simple problems in the application of hydraulic steering organization mainly include heavy steering, steering deviation, steering wobble and abnormal noise in steering。The steering is heavy because the steering hydraulic power system does not work, and it has nothing to do with the steering machinery。The detailed causes of heavy steering are: lack of hydraulic oil;The sealing function of the system is poor, and air enters the hydraulic system;The gear pump chamber of the hydraulic pump is seriously worn or the belt gear of the hydraulic pump is damaged, which can cause the hydraulic power system to not work。

Truck mounted craneThere are many methods of power steering system, but now most of the crane is commonly used hydraulic power steering system, so we in the usual use, for the hydraulic power steering pump in the use and maintenance of what attention, today we will take a detailed look。 In general, in normal use and maintenance, for hydraulic power steering pumps, the need to pay attention to the following points: 
AIf the car is stopped for a long time, when restarting the liberation of the crane, do not work at full load immediately, at least work without load10Minutes, wait for the booster oil and other oil to reach the normal working condition before driving。

AOften check the use of power oil, the use of power oil is necessary to keep clean。Replace the power oil regularly, and it is necessary for the owner of the crane to have filtration equipment when filling the power oil by himself。

AWhen using the hydraulic power steering pump, pay attention to choosing the right type of lift oil, otherwise it will affect the working power and service life of the power steering pump。

Hydraulic cylinder of truck crane is an important part of hydraulic boom，In the use and maintenance should pay attention to the following problems: the cylinder can not work in the bending state;The working face of the piston rod is strictly prohibited from chafing;The anti-rust oil on the piston rod (new equipment) should be washed with gasoline before use，Otherwise, anti-rust oil will damage the oil seal;When the hydraulic boom of the crane is parked for a long time，Some necessary anti-rust measures should be taken，For example, replace the high-quality new oil or discharge the hydraulic oil in the cylinder，Then seal the end of the cylinder with anti-rust oil;The working face of the cylinder should be kept clean frequently，Avoid breaking the tightness of the oil seal，Do not use cotton when wiping the work surface，To prevent the cotton wool from getting caught in the oil seal。 Precautions for the use of high pressure hose: do not pull too tight when connecting;Do not twist when connected;Do not bend sharply when connecting, and do not bend at the end;Avoid being subjected to shear impact, clamping, etc.;When replacing a hose, ensure that the pipes are clean inside and outside, and that the end of the spare hose is covered with a dustproof cover。 While paying close attention to the quality of the main engine products, the truck crane also cooperates with the major truck chassis manufacturers to select all kinds of enhanced truck crane special chassis, fully ensuring the good match between the truck crane and the chassis, and ensuring the service life of the truck crane and the whole vehicle。
