Abstract
A lightweight platform dolly with a one-piece lightweight composite fabricated support platform has a rectangular support platform with at least one bumper block. The bumper blocks can be adjusted to accommodate varying loads and conditions. The adjustable bumper blocks change the length or width of the lightweight platform dolly, raise the load on the lightweight platform dolly for better vertical clearance, and enable the lightweight platform dolly to accommodate uneven bottom items. The bumper blocks are secured with flexible hinges and T-Bar block holders and receivers, which can secure loads.
