MMH - Mechanical Aids: Levers and Rollers

A lever is a bar or rod that reduces the effort required when lifting loads. To be effective, the lever must rest on a pivot (fulcrum). Levers reduce the force required to handle materials and reduce bending and stooping.

• Use a steel bar to shift an object horizontally.

• Use "Come-Alongs" to move a heavy load. Make sure the load is fully on the skid to prevent drag or resistance.

• Mount the lever on wheels to assist when moving the load. Make sure that the wheels can be locked.

Lever on a rolling platform lifts and moves objects.

• Use an extended handle to lift, shift, or move objects without bending.

Rollers are cylindrical objects that reduce friction, making it easier to move heavy loads across a surface. When used with levers, rollers provide additional efficiency in material handling tasks. 

• Place rollers under the load to move it horizontally with less effort. 
• Use levers to lift the load and rollers to glide it across the surface. 

• Use rollers positioned at an angle to redirect the load smoothly. This technique reduces the need for manual repositioning. 

• Rollers can assist in moving loads up or down an incline when used with a braking or anchoring system for control. 
• Make sure rollers are stable and evenly spaced under the load to prevent tipping. 
• Do not use rollers on uneven or soft surfaces.
