Abstract
A crawler belt vehicle comprises a chassis, a pair of first wheels mounted on the chassis, a pair of second wheels mounted on the chassis, a pair of crawler belts each trained around the first pair of wheels and the second pair of wheels, and a pair of equalizers each for pressing one of the crawler belts against a ground. Each of the crawler belts has low-friction members spaced-apart from each other in a longitudinal direction of the crawler belt. Each of the equalizers has a leaf spring having a first end connected to the chassis and a second end opposite the first end, and a slider supported on the second end of the leaf spring for undergoing pivotal movement about an axis extending in the longitudinal direction of the crawler belt for pressing the crawler belt against the ground by the resiliency of the leaf spring.
