  & nbsp; We may not be unfamiliar with hydraulic lifting channels, which are equipment used for high-altitude operations and can assist us in successfully completing our mission. However, we are not very familiar with the maintenance methods of hydraulic lifting channels. Improper maintenance methods can affect the functionality and service life of the machine, which can easily lead to problems with the hydraulic lifting channels. Next, let's learn the correct maintenance method for hydraulic lifting channels.



  & nbsp; When personnel enter the interior of the lifting platform for maintenance, it is necessary to lift the elevator to avoid sudden descent and injury to personnel. Check the rollers, central axis, and bearings; Oil cylinder pin and bearing; The smoothness and wear condition of the arm hinge shaft and bearings; Add smooth oil to the above components. Extend the service life of bearings.

  & nbsp; Check the quality and level of hydraulic oil. When the lifting platform is raised to a high position, the hydraulic oil level should be 40-50 millimeters above the bottom of the oil tank. When the color of hydraulic oil becomes darker, the oil quality becomes sticky, or there are foreign objects such as gravel in the oil, the hydraulic oil should be replaced in a timely manner. The hydraulic system of the lifting platform uses 32 # hydraulic oil. Hydraulic lifting platform is a lifting machinery that vertically transports people or objects.

  & nbsp; It also refers to equipment used for vertical conveying in logistics systems such as factories and automated warehouses. Various flat conveying devices are often installed on the lifting platform as connecting devices for conveyor lines of different heights. Generally, hydraulic drive is used, hence it is called a hydraulic lifting platform.
