The Beta Tools C30S Tool Maxi Tank Tool Storage design has a built-in hydraulic jack to raise the unit when users want to move it, then allowing users to lower the jack for stationary positioning. Lowering the jack causes the unit to sit on its steel legs rather than the casters, providing a more stable foundation. The C30S features a 4,000-lb weight load capacity so technicians can use the top as a workbench for heavy items such as engines and transmissions. Beta Tools designed the worktop as a fluid collection pan for techs working on equipment where fluid may leak onto the worktop surface. To drain the fluid that has collected in the pan, simply raise the hydraulic jack which raises one side, causing the fluid to drain to the opposite side and exit out of the bottom drain plug.
