Crane hydraulic cylinders are critical components in the heavy machinery and construction industries, enabling precise and powerful lifting, lowering...

The hydraulic cylinder is small in size and light in weight, so the inertial force is small. When suddenly overloaded or parked, no big impact will occur. It can automatically adjust the traction speed smoothly within a given range, and can complete the speed regulation. The commutation is simple, and the conversion between the rotation of the working mechanism and the linear reciprocating motion can be completed more conveniently without changing the rotation direction of the motor. The hydraulic pump and the hydraulic motor are connected by oil pipes, and they are not severely restricted by each other in spatial arrangement. Because the oil is selected as the working medium, the relative moving surfaces of the components can be lubricated by themselves, with small wear and long service life. Check the hydraulic system once every day. Including check the motor operation, hydraulic pump operation, each solenoid valve is sensitive, etc. If there is an anomaly, deal with it immediately. Otherwise, it shall not operate. Regarding the determination of the output speed of the electric equipment, when the valve has no strict requirements for its opening and closing time, the slower speed should be selected as far as possible.

The gap between the cylinder barrel and the piston in the hydraulic cylinder is mainly determined by the size of the cylinder and the seals used in the standard spacing. These two are used to choose. The use of the cylinder, in general, there are four main types, is the boom on the elastic cylinder and luffing cylinder, as well as the leg on the elastic cylinder and straight cylinder. Among them, the boom elastic oil cylinder is used to adjust the boom length, and the boom luffing oil cylinder is used to adjust the boom elevation angle.
