  • Crane Counterweight Hydraulic Cylinder

    Crane Counterweight Hydraulic Cylinder

    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

    Hydraulic Cylinder for Crane Support Legs

    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.
  • CHM Universal Vises

    CHM Universal Vises

    CHM Universal Vises are composed of two parts: a precision tool flat-nose pliers and a turntable base.

  • Common Faults and Repair Methods of Hydraulic Cylinders

    1. Oil leakage: Hydraulic cylinder oil leakage is common in sealing interfaces such as the joint between the cylinder sleeve and the cylinder head, and the friction surface between the piston rod and the guide sleeve, which usually points to the aging or damage of the sealing element.

  • What is a CNC machine vise?

    CNC machine vise is an industrial clamp that we often use in machining. It is usually installed on milling machines and drilling machines. A vise is a commonly used machine tool accessory, mainly used to clamp and fix workpieces on CNC machine tools or ordinary machine tools for machining operations.

  • New developed product

    As a reliable manufacturer in the field of hydraulic cylinders and CNC machine tool accessories, Qingdao Micro Precision Machinery Co., Ltd. has always insisted on innovation-driven development and is committed to providing customers with high-quality and high-performance products.

  • Should the relief valve be installed before or after the check valve?

    As a hydraulic equipment manufacturer, we often think about the installation order of relief valves and check valves when designing hydraulic systems. Both valves play an important role in hydraulic systems. The relief valve is mainly used to protect the system from damage caused by excessive pressure, while the check valve is used to prevent the reverse flow of oil.

  • Is it worth repairing a leaking hydraulic cylinder?

    Hydraulic cylinders are critical components in various industrial and mobile equipment, responsible for converting hydraulic energy into linear motion. Over time, wear and tear can lead to leaks, often caused by damaged seals, worn cylinder walls, or piston rod issues. Deciding whether to repair or replace a leaking hydraulic cylinder requires careful evaluation of its condition, including internal damage, piston rod integrity, and overall service history.

  • What Makes a Tower Crane Lifting Cylinder Essential for Stable and Efficient Hoisting?

    ​In modern construction projects, the efficiency and safety of hoisting operations heavily depend on the quality and reliability of the Tower Crane Lifting Cylinder. This hydraulic component plays a decisive role in lifting performance, load stability, and long-term durability. Whether used for height adjustment, jib luffing, or tower section climbing, a well-engineered lifting cylinder determines how safely and smoothly a tower crane operates onsite. As a manufacturer focused on precision hydraulic solutions, Qingdao Micro Precision Machinery Co., Ltd. provides advanced lifting cylinder systems designed for demanding construction environments.
