ScaffoldMart.coms Heavy-Duty Caster Wheel
Here’s the lowdown on our caster. We have now sold in excess of 400,000 of these. This wheel is very heavy duty. The steel body is not quite as beefy as the more expensive polycarbonate one, but it’s plenty of wheel for 95% of all applications. Works very nicely in highly demanding rental operations. It loads to 8,100 pounds in load tests which is actually higher than the polycarbonate wheel...
The stem on our caster this caster wheel is 1.375" OD (#6 tube) with a 4 inch length. It has a double safety margin built into the load rating. Our wheel is heavy duty, load tested to handle 500 pounds with an 8-to-1 safety margin. (See our scaffolding load test results here.)
The scaffold caster wheel is an 8" cast-iron wheel with a rubber overlay that is 2 inches wide and over an inch of rubber covering the iron caster wheel. There are ball bearings in the pivot mechanism to handle high loading. Double zirk grease fittings. Double lock to maintain rock solidness. Locks to prevent wheel pivot and locks to prevent the scaffold caster wheel from rolling. Upper steel body is galvanized. Hole location on stem is 2.5 inches from the base. In short… why pay more?
