The pump cart is a 50 ton capacity cart with articulating steering. The axles each have approximately 22 degrees of steering. Steering is controlled by pulling the tongue to the right or left. There is a tongue on each end of the cart so that the load can be pulled and steered in either direction. When steering, a hydraulic cylinder is activated and the axle at the opposing end of the dollie will turn as well. Both axles can be turned by steering only one tongue.
If needed a small 24 volt hydraulic pump can be used to put the cart into a crab steer mode. When done utilizing the crab steering, the pump can be used to time the axles and pressurize the hydraulic system.
