摘要： A dolly with a one-step injection molded one-piece plastic frame is provided. The frame includes a pair of substantially parallel longitudinal side members and a pair of substantially parallel transverse side members which form a generally rectangular frame having corners. A bottom of the dolly is at least partially formed in a honeycomb/cellular configuration. A plurality of casters are mounted to the bottom of the frame via a plurality of caster fastening bolts which are received in a corresponding plurality of caster fastening holes disposed at the corners. The dolly may also include a riser block disposed on a top of the frame along a side member and secured to the frame by the caster fastening bolts. A rubber pad may be disposed on the riser block and secured between the riser block and the top of the frame. The dolly may also include a channel in the bottom of one or more side members for receiving a reinforcing member.
