Crane Counterbalance Hydraulic Cylinder

Specially customized non-standard A6610 hydraulic cylinder relief valve block material: Any material specified by the customer is accepted, and a material test report is attached.
The valve hole of the specially customized non-standard hydraulic valve block adopts cone surface sealing to ensure small leakage. It is also suitable for low-viscosity working media such as emulsion. It has a simple structure, reliable operation and high degree of standardization.

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.

Crane telescopic hydraulic cylinder is a device that uses a hydraulic system to achieve telescopic function, and is mainly used for crane boom telescopic. It consists of an outer cylinder, an inner cylinder, a piston, a seal, a tie rod, and a hydraulic oil pipeline. The pressure of the hydraulic oil drives the piston to move, thereby driving the inner cylinder and the tie rod to telescope, realizing the telescopic function of the crane arm.

The ER series collet is a cylindrical collet used on machine tools, mainly for securing and clamping drilling and tapping tools or milling tools.
Collet can be customized to different sizes as customer's requirement.

Customized Welded cylinder Base, also known as welded cylinder base end, is specially processed as customer's drawing and special requirement. The main function is to form an enclosed space with the cylinder to accommodate the hydraulic oil and piston assembly, while ensuring the tightness of the hydraulic cylinder, preventing oil leakage, and providing support for the piston rod and the whole hydraulic cylinder to ensure its stable work, which is similar function as common welded cylinder base.
