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 Support Legs is an important part of the crane outrigger system. It adopts the hydraulic transmission principle and drives the outriggers to extend and retract through liquid pressure to achieve stable support of the crane. The hydraulic cylinder is mainly composed of cylinder barrel, piston, seal and guide sleeve. The hydraulic oil enters the cylinder barrel through the pipeline, pushing the piston to reciprocate in the cylinder barrel, thereby realizing the extension and retraction of the outrigger.

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.

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.

Retention Knob JIS B6339-1986, as stipulated by the Japanese Industrial Standards, are pull studs used in CNC machines to connect tool holders and draw bars, securely pulling the tool holders into the spindle. They are also known as retaining screws or pull knobs. Pull Studs can be customized to different sizes as customer's requirement.
