Load equalizing dollies use specially formulated, non-marking synthetic wheels for the ultimate in floor protection. In the 14, 28, and 42 ton sets, individual wheel loads are less than 1750 lbs. at rated capacity. Wheels are fitted with shielded ball bearings for low rolling resistance. Steering dollies have oscillating “wheel boxes” to prevent edge loading. The design of the system insures equal load distribution over the multi-wheel arrangement. Steering dolly wheels are located on either side of the swivel, allowing counter -rotation around the swivel when being turned. In many cases the swivel dolly may be turned while stationary . All dollies have fully supported axle ends. This helps prevent axle flex as is common in cantilever style units. Fully enclosed frames help prevent wheel damage. The modular format allows conversion to a four point system when required, or the rear dollies may be used alone without the swivel dolly. The system may be easily disassembled without the use of tools for easy transport.
