MMH - Mechanical Aids: Levers and Rollers
On this page
Why and how should levers be used?
Back to topA lever is a bar or rod that can be used to reduce the effort when lifting loads. To be effective, the lever must rest on a pivot (fulcrum). Using levers reduces the force required to handle materials and avoids bending and stooping.
- Use a steel bar to shift an object horizontally.

- Use the lever and rollers to move a load horizontally.

- Use rollers on an angle to change the direction of the load.

- Use "Come-Alongs" to move heavy load. Ensure load is fully on the skid to prevent drag or resistance.

- Mount lever on wheels to assist in when moving load. Ensure that wheels can be locked.
