Signs that You Need to Replace Your Swing Drive Gearbox

  • Unusual noises or vibrations during rotation
  • If you hear strange noises or feel unusual vibrations during the rotation of your mobile crane, it may be a sign that your swing drive gearbox needs to be replaced. These noises and vibrations can indicate that the gears are worn out or damaged, or that the lubrication system is not working correctly.

  • Leaking oil
  • If you notice oil leaks around the swing gearbox, it may be a sign of a damaged seal or gasket, which can compromise the performance and lifespan of the gearbox.

  • Reduced rotation speed or power
  • If the crane’s rotation speed or power has decreased, it may be due to a malfunctioning gearbox. This can be caused by worn out or damaged gears, a damaged hydraulic motor, or a clogged filter.

  • Increased wear and tear on other crane components
  • An old or damaged swing gearbox can cause increased wear and tear on other crane components, such as rollers and slewing rings. If you notice increased wear and tear on these parts, it may be time to replace your swing drive gearbox.

Swing Gearbox Buying Guide

When purchasing a swing gearbox, it is important to determine which parameters need to be considered to ensure compatibility with your mobile crane. Below are some key parameters to keep in mind:

Parameter Description
Rotation torque This refers to the maximum torque that the gearbox can provide during rotation.
Rotation speed This refers to the maximum rotation speed that the gearbox can handle.
Mounting type There are different types of mounting options, such as flange and foot mounting. It is important to ensure that the mounting type of the gearbox matches that of the crane.
Shaft diameter This refers to the diameter of the gearbox’s output shaft. It is important to ensure that the shaft diameter is compatible with the crane’s input shaft diameter.
Operating temperature range It is important to ensure that the gearbox can operate within the temperature range of the crane’s working environment.
