Omega Truck Ramps have a 20-ton capacity and support truck tires up to 15-1/2" wide. Specifically designed for heavy-duty tasks, Omega Truck Ramps are designed to safely support rated-capacity vehicles for extended periods but are not to be used to simultaneously support both ends or one side of a vehicle. A heavy-gauge steel frame helps prevent distortion and twisting, and a large-wheel design provides extra durability. A non-skid rubber matting enhances operation safety, and compliance with factory standards ensures safety, strength and stability. A 33-1/2" long, retractable T-handle increases mobile efficiency and allows for easy positioning, and Omega's truck ramps are sold in pairs and to be used only in pairs.
