Description Model 30 Rigid Caster is a step up from the rigid casters shown on Model G15. These Rigid casters have larger wheels, big wheel bearings, a higher weight load capacity rating, and a larger mounting plate than the caster that is shown on G15. It utilizes superior performance on both automated and hand powered equipment. The 30 Rigid Caster frames are plated in zinc for rust prevention. There are grease fittings for the wheel bearings. Rigid plate casters are usually attached to machinery at the opposite end of the push handle and where casters with swivels are attached. This enables the employee pushing the equipment to be able to control the line of travel. It should also be stressed that rigid plate casters have two legs horizontal to the mount plate, preventing sideways movement. Equipment with two rigid casters and two swivel casters must be handled into position. Capacity up to 7,000 pounds per plate caster. Model 30 features a large swivel and wheel bearing which allows for heavy loads and more arduous service. This caster is also available in 304 Stainless Steel as the SS-30 for wet or corrosive applications. For more details and assistance placing an order, contact us at 800-501-3808.
