• Truck weldment uses formed-channel sides and structural steel plates complete with welded girder
pads and end plates, forming a rigid U-shaped structure.
• Wheels are solid forged steel and rotate on two sealed, lifetime-lubricated ball bearings and are heat
treated with a hardness of 220-250 BHN.
• Single-flange wheels have a compound tread for operation on American Standard I-beams or wide
flange beams.
• Wheel diameter is 4” on 3-ton trucks and 6-1/2” on 5-ton trucks. Patented track wheels are available for
both capacities.
•  Push-type and geared-type, under-hung end trucks are designed in accordance with CMAA specifications.

• Wheels are 8” diameter and made of high-strength, ductile iron with a hardness of 187- 255 BHN.

• Wheels have a cylindrical tread designed to fit 20# to 45# ASCE rails.

• Width between wheel flanges is 2-3/4”.

• Wheel bearings are lifetime-lubricated, precision ball bearings, providing a minimum of 5000 hours performance in accordance with CMAA specifications.

• Maximum allowable wheel load is 6500 pounds (per pair).
