RA 850-137-146

Frequently Asked Questions

Q: Which Raymond pallet jack model uses the RA 850-137-146 brake drum?
A: The RA 850-137-146 brake drum is compatible with Raymond model 101 walkie electric pallet trucks. Verify your truck is model 101 before ordering to ensure proper fit.

Q: What is the function of a brake drum?
A: The brake drum is a cylindrical component that works with brake shoes or pads to slow and stop the pallet truck. The drum surface provides the friction interface for braking. When the brake is engaged, the pads press against the inside surface of the drum to create stopping force.

Q: What material is the RA 850-137-146 made from?
A: Brake drums for electric pallet trucks are typically cast iron due to its heat dissipation properties and wear resistance. Cast iron can handle repeated braking cycles and maintain consistent friction characteristics over time.

Q: What symptoms indicate a brake drum needs replacement?
A: Replace the brake drum if you observe reduced braking effectiveness, grinding noises when braking, visible scoring or deep grooves on the drum surface, or if the brake pedal feels spongy or unresponsive. These conditions affect truck safety and stopping distance.

Q: How do I know if the brake drum is wearing unevenly?
A: Uneven brake drum wear causes pulling to one side during braking, vibration in the steering, or soft brake response. Inspect the drum surface for uneven grooves or discoloration. Uneven wear often indicates misaligned brake shoes that need adjustment.
