Working principle:

The Luffing hydraulic cylinder adopts the principle of hydraulic transmission, and the hydraulic system provides pressure oil. When pressure oil enters the chamber of the hydraulic cylinder, the piston is subjected to pressure force, resulting in linear motion. This movement is connected to the structure of the crane to achieve the lifting operation of the crane.

Function on the crane

Luffing hydraulic cylinder plays an important role in cranes, mainly used to control the lifting system of the crane. Specifically, its functions include:

  1. Lifting function: The Luffing hydraulic cylinder drives the lifting mechanism of the crane by controlling the movement of the piston, enabling the lifting arm or bridge to achieve upward and downward movements. It can provide sufficient strength and control performance to cope with various lifting tasks.
  2. Load bearing: The Luffing hydraulic cylinder bears the load of the crane lifting system, including the boom, hook, and the lifted goods. It needs to have sufficient load-bearing capacity and stability to ensure that the lifting system can operate safely and smoothly.
  3. Motion control: By controlling the pressure and flow of the Luffing hydraulic cylinder through the hydraulic system, precise control of the crane lifting system can be achieved. This allows the lifting operation to be finely adjusted as needed to meet various work requirements and safety standards.
    In summary, the Luffing hydraulic cylinder is a hydraulic cylinder used in the lifting system of cranes. It controls the linear movement of the piston through hydraulic force, achieving the lifting function of the crane. It plays an important role in driving the lifting system, carrying loads, and providing motion control on cranes.

How toMaintain the Hydraulic Cylinder of Crane?

The maintenance and upkeep of the lifting hydraulic cylinder of the crane is very important to ensure its normal operation and extend its service life. The following are some common maintenance and upkeep measures:

  1. Regular inspection: Regularly inspect the appearance and connecting components of the hydraulic cylinder, including seals, bolts, pipelines, etc., to ensure that there are no leaks or looseness. Simultaneously inspect the surface of the piston rod for wear or damage, as well as the hydraulic cylinder for deformation or cracks.
  2. Cleaning and maintenance: Keep the hydraulic cylinder clean. Regularly remove dirt and debris from the surface of the hydraulic cylinder to prevent it from entering the seals and piston rods and causing damage. Cleaning agents and soft cloth can be used for cleaning.
  3. Lubrication: According to the requirements of the hydraulic cylinder, regularly add appropriate lubricants, such as hydraulic oil or grease, at the specified positions. Ensure that the piston rod and seals of the hydraulic cylinder maintain good lubrication during movement, reducing friction and wear.
  4. Seal maintenance: Seals are an important component of hydraulic cylinders, and inspection and maintenance of sealing performance are particularly important. Regularly check the wear and aging of the sealing components, and if any problems are found, replace the sealing components in a timely manner to ensure good sealing effect.
  5. Pressure testing: Regularly conduct pressure testing on hydraulic cylinders to ensure they can withstand the rated working pressure. During testing, attention should be paid to safety, following the correct operating steps and the specified pressure range.
  6. Pay attention to the working environment: Avoid prolonged exposure of hydraulic cylinders to high temperature, humidity, or corrosive environments, which may cause damage to the sealing and materials of the hydraulic cylinders. Maintain a dry and clean working environment, and take appropriate protective measures.
  7. Regular maintenance: Develop a regular maintenance plan based on the usage of hydraulic cylinders and the manufacturer's recommendations. Regular maintenance and repair, including cleaning, lubrication, replacement of worn parts, etc., to ensure the normal operation and performance of the hydraulic cylinder.

It should be noted that the maintenance and upkeep of hydraulic cylinders should be carried out by experienced professionals. For complex maintenance work, it is best to seek support and guidance from manufacturers or professional maintenance organizations. Maintaining maintenance records and promptly addressing and repairing discovered issues can improve the reliability and safety of hydraulic cylinders.
