Heavy Duty
Just Got Much EasierWith Darcor's Multi-Wheel KP Casters

Our unique double and triple-wheel Kingpinless (KP) casters represent an important new solution for a wide variety of heavy duty applications. Reasonably priced multi-wheel KP casters from Darcor widely outdistance their heavy duty single-wheel competition. Darcor delivers higher load capacity, sharply lower starting and swivelling forces, a choice of wheel sizes and superior materials, and many other advantages.

If your heavy duty operations have been compromised by high push-pull forces (and resulting on-the-job injuries), noisy wheels, premature caster failure and more, a better answer is now at hand with Darcor's attractively priced multi-wheel KP casters. In short, heavy duty just got much easier and cost effective.

The Darcor KP dual and triple-wheel caster advantages:

Reduced starting, rolling and swiveling forces.
Much easier movement means fewer workplace injuries and significantly greater productivity.
Greater swivel offset for better swiveling forces.
Better performance under loads up to 6,000 lbs.
Choice of wheel configuration, size and type.
Depending on the operating environment, pick dual or triple wheels in six or eight inch diameter--in Solid Elastomer (SE), for normal conditions, or Neoprene (D) for uneven floor surfaces and debris.
Bigger load capacity. Lower overall height.
In applications where height is an issue, Darcor's KP casters deliver a half-inch height advantage for eight inch-wheels, and 2.5 inches of clearance for six-inch wheels.
Longer lasting under the toughest conditions.
Darcor casters are built and tested to live longer. The result: lower financial and environmental cost.

DARCOR triple KP with Solid Elastomer (SE) wheels: the best overall heavy duty solution.

Overall, testing results establish Darcor's superior heavy duty performance:

Darcor's eight-inch triple PSE wheel KP caster (31-KP3408-PSE) was the best performer when compared to our own single-wheel heavy duty solution (8-808-PSE) and to our closest competitors' heavy duty casters.
Under a 4,000 lb weight load, Darcor's eight-inch triple-wheel KP caster (31-KP3408-PSE) required less than half the starting and swiveling force of our closest competitor's eight inch single-wheel heavy duty casters.
While Darcor's Solid Elastomer (SE) triple wheel KP caster tested as the best overall performer. Darcor's Neoprene (D) triple wheel KP caster also handily outperformed the competition.
Tests at 2,000 and 6,000 lbs. demonstrated similar superior performance using our triple-wheel KP caster.
For loads less than 2,000 lbs., Darcor also offers double-wheel KP casters (with six or eight-inch wheels) offering similar performance advantages.
