All measurements indicate the wheel diameter by the tread width.
The below capacity ranges indicate the working (dynamic) load that each caster will support. A safety factor should be included in your formula to determine your required load rating per caster.
W/(C-1)=R W is total weight needed to move. C is total number of casters required. R is ideal load rating, with safety factor built in. Divide the total load weight by one less caster than you will use to safely determine load rating.
Plate dimensions shown are overall mounting plate size.
When replacing existing casters, select the closest plate size and verify bolt-hole compatibility.
BHP = Bolt Hole Pattern, shown under each plate.
The SPWH Series puts a spring suspension into Hamilton's proven Workhorse rigging — up to 1,200 lb per caster. The spring absorbs floor-seam, dock-plate, and tow-bar impact so it isn't transmitted into the load, the equipment, or the operator; the Workhorse base provides the track record underneath.
















































Hamilton's Workhorse line is one of the most-specified industrial caster platforms there is. The SPWH series adds a built-in spring to that rigging: as the caster crosses an impact, the spring compresses and absorbs the shock. You get the suspension benefit — less product damage, less equipment fatigue, less operator strain — on a rig base with a proven service record, not an unfamiliar platform.
Tow-line carts that take start-stop coupling shock, equipment crossing rough floors and expansion joints loaded, and material-handling rigs that carry sensitive loads. At up to 1,200 lb per caster, SPWH covers the medium-duty range where shock absorption matters but the load doesn't require a heavier spring platform.
Spring-Loaded Workhorse — Hamilton's proven Workhorse rigging with a built-in spring suspension, to 1,200 lb per caster.
It compresses over impacts — floor seams, dock plates, tow-bar shock — absorbing the hit instead of transmitting it to the load and equipment.
Both are spring-loaded. SPWH builds on Workhorse rigging (to 1,200 lb); SPCH builds on Champion rigging (to 1,630 lb).
Our US-based caster engineers will match the right build to your load, floor, and application.
