Electric ManliftThe manlift is an important piece of equipment in our industry. When used properly it is a very useful and laborsaving tool. However, when manlift safety rules are ignored, problems can occur.

In general, the gates must be self-closing (not tied open). The manlift entrance and exit platforms must be dry and free of clutter. The manlift should be used only to carry people. The manlift should never be used to carry tools, equipment, materials, or supplies. The entire manlift must be inspected at least monthly.

Electric Manlift Safety Rules1. Only authorized personnel may use the manlift.

2. All employees required to use the manlift must know and understand the basic operation.

3. Manlifts are designed to carry personnel only. The manlift shall NOT be used as a freight elevator to carry tools, equipment, materials, or supplies.

4. All entrance and exit floor levels must be kept clean, dry, and free of clutter.

5. Self-closing doors must be operating correctly at all levels to close off entry to the manlift shaft way if the car is not present on that level.

6. All safety interlocks and limit switches must be in working condition. The manlift car should not move if limit switches are operating properly and a door is open.

7. Emergency alarms must be functioning properly.

8. Manlift car and shaft way lights should be working properly if applicable.

9. Load limit signs must be posted inside the car.

10.Emergency procedures should be reviewed in the event of a malfunction.

Inspect the under carriage of the car making sure all electrical connections to the junction box are tight and not cracked or broken. Make sure the electrical power cord is traveling in the correct position when moving up or down and not rubbing on the framework creating a bare spot. Check the car guides on the rail for tightness and wear.

The person that checks the head pulley area should also check all of the electrical connections, limit switches, bearing supports, pulley wear, and guards, etc.

Inspect the top drive sheave for condition of the cable grooves. Look for wear spots that could damage cable during travel

Inspect the set screws in the center shaft of the drive pulley to make sure they are tight
