The double speed electric hoist is an electric hoist that integrates normal speed and slow speed. Other than that, it is basically the same as ordinary electric hoist, so it is basically the same as ordinary electric hoist in use.

  • The newly installed double speed electric hoist should be used for empty test run several times before use, but before the installation is complete, remember to power on the test run.
  • Before normal use, the double speed electric hoist should be subjected to a static load test with a rated load of 125%, lifting about 100 mm from the ground, and 10 minutes to check whether it is normal.
  • In the use of the double speed electric hoist, it is absolutely prohibited to use it in an environment that is not allowed, and when it exceeds the rated load and the rated number of closings per hour.
  • It is not allowed to press two flashlight door buttons that make the electric hoist move in opposite directions at the same time.
  • The double speed electric hoist should be operated by a dedicated person. Should the operator fully grasp the safe operation regulations? It is strictly forbidden to pull the inclined crane.
  • The double speed electric hoist must maintain sufficient lubricating oil during use, and keep the lubricating oil clean, and should not contain impurities and dirt.
  • When the double speed electric hoist is not working, it is not allowed to hang heavy objects in the air to prevent permanent deformation of the parts.

The main difference between the double speed electric hoist and the ordinary electric hoist is that it can be accurately positioned. When the normal speed cannot reach the specified position accurately, the slow speed can be used for adjustment.
