Crane counterweight hydraulic cylinder is an important device that realizes crane balance through hydraulic transmission mechanism. It is mainly composed of cylinder body, piston, piston rod, sealing element, oil filter, hydraulic pipeline and oil tank. The working principle is based on Pascal's law, that is, in a closed container, pressure is transmitted to every point in the liquid, and the pressure acting on the liquid is proportional to the area. When the crane is lifting, the hydraulic pump presses the oil into the cylinder, causing the piston to rise, thereby increasing the hook height. When the load of the crane increases, the oil inside the cylinder will be compressed and the piston will drop, thus achieving the balance of the crane.

Hydraulic Cylinder for Crane Deployment usually refer to hydraulic actuators used to deploy, extend or arrange specific parts in the structure of the crane. For example, the boom of some cranes needs to be extended and retracted by hydraulic cylinders to adjust the length and angle; or the outriggers of some foldable cranes need to be deployed and fixed with the help of hydraulic cylinders to ensure the stability of the crane during operation.

Oil seal RS series, also known as the piston rod one-way sealing ring, is composed of an anti-wear filled polytetrafluoroethylene PTFE ring and an O-type rubber sealing ring. The O-type ring provides elasticity to compensate for the wear of the PTFE step ring and only has a one-way sealing effect.

Hydraulic bushing is an economic component in hydraulic cylinders and hydraulic equipments. It could be as the start or end of the installation distance, and mainly has the supporting function in hydraulic equipments.
It's important to select the suitable hydraulic bushing, which could get better performance for the equipments.
