Industrial PU Wheel Chocks

Yescom USA, Inc. model 33WCK003-WC009-01 wheel chocks are engineered for semi-trucks, commercial trailers and heavy-duty logistics equipment. The high-density polyurethane construction supports a 198,400 lbs weight capacity for demanding industrial safety applications.

90-Ton Capacity and 50-Inch Tire Fit

Each chock weighs 14.4 lbs and measures 12.600 by 13.780 inches to accommodate tires up to 50 inches in outer diameter. The 90-ton rating provides a rock-solid barrier for agricultural tractors, excavators and other oversized machinery where smaller blocks would be insufficient.

Polyurethane Durability and Traction Ribs

Premium PU material is 3-5 times more durable than rubber and resists oils, fuels and chemical degradation across a -20°C to 100°C range. Deep horizontal traction ribs bite into tread to prevent slippage on mud, snow or smooth dock surfaces while the vibrant yellow finish ensures high visibility.

Questions about this item

Will these 90-ton PU chocks work with the rubber chocks I already use for lighter trailers?

Yes, the 14.4 lb polyurethane chocks can supplement existing rubber blocks; their horizontal traction ribs grip 50-inch tires on mud, snow or dock surfaces without marking the floor.

How do I confirm the chocks are seated correctly after positioning them against 50-inch tires?

The deep horizontal ribs should visibly bite into the tread and the bright yellow body stays fully visible; no movement should occur when the 198,400 lb rated load is applied.

Does the package include mounting brackets or ropes, or must I buy them separately?

Only the pair of 11 7/16" H x 14 15/16" L x 11 13/16" W polyurethane chocks is supplied; brackets, ropes or chains are not included.
