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 flange is welded together with the hydraulic cylinder, connect with the tube so that the hydraulic oil can enter the cylinder pipe smoothly, and ensure the piston rod to stretch out and draw back in normal. Qingdao Micro Precision Machinery Co., Ltd. is a professional manufacturer and supplier that mainly produces hydraulic parts and hydraulic cylinders with reliable quality and stable delivery, which has many years experience.

The ER tool holder is a commonly used tool holding device in machine tool processing, mainly used for fixing and clamping straight shank tools, such as drills and milling cutters, it's also called milling chuck arbor.
Tool holder can be customized to different sizes as customer's requirement.
Its common specification includes BT30, BT40, BT50 etc.

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.

The China Tower Crane Lifting Cylinder produced by Micro Precision Machinery features an advanced hydraulic system that delivers stable, powerful force for precise load handling. Its durable design ensures smooth operation and high efficiency, enhancing safety and productivity in heavy-duty construction lifting applications.
