[0029] Please refer to Figures 1 to 3 for a description of the dump truck battery rack provided by this utility model. A dump truck battery rack includes a base 10, a support bracket 20, and a set of support members 30. The base 10 is a long strip structure used for fixed installation on a dump truck and is arranged along the length of the dump truck. The upper surface of the base 10 has a first mounting area 11 and a second mounting area 12 arranged adjacent to each other. The base 10 has a clearance groove 13 located below the second mounting area 12.
