Checking Electric hoist control Buttons: Markings & Operation

Control buttons should be inspected to make sure they are labeled clearly and correctly. This inspection is one of the pre-operational inspections which should be conducted before using a powered electric hoist.

Warnings before testing the pendant’s operation

• Ensure the area under the electric hoist or crane is clear of obstructions.
• Make sure there is no one under or in the path of the electric hoist, including yourself.
• Do not put loads on the electric hoist during this test.
• If the limit switch fails, make sure you do not run the bottom block into the electric hoist, drum or trolley. This action can damage the electric hoist. Please note that some electric hoists do not have limit switches.
• Be prepared to stop the electric hoist by releasing the controller.

Once you have taken these safety precautions, you are ready to operate and test the electric hoist controls.

Follow the procedures to check for proper operation: First, you need to verify the markings on the pendant are correct – that “up” moves the electric hoist up and “down” moves the electric hoist down.

• 1. Test that the trolley controls move the trolley left or right as indicated on the pendant buttons.
• 2. Test the bridge to ensure it moves as specified on the pendant.
  – Check any warning devices on the pendant as well, if applicable. For example, horns, an indicator light, etc.
  – Make sure Electric hoist controls were not modified or safety features were not disabled. T Do not operate any electric hoist with modified Electric hoist controls.
  – One suggestion: labeling Electric hoist controls with “north,” “south,” “east” and “west” instead of “left’ and “right” to avoid any confusion.
  – All functions of the electric hoist must work properly and as marked on the pendant. If not, the electric hoist must be taken out of work.

Once you have ensured the electric hoist controls are clearly marked and functioning properly, you are ready to operate your electric hoist.
