Abstract:
1. A trolley assist-capable mining truck comprising: a frame; a plurality of ground engaging wheels coupled to the frame; a braking system coupled with the plurality of ground engaging wheels, and having a friction braking mechanism including an electrically actuated valve and a regenerative braking mechanism; a line connecting mechanism configured to couple the regenerative braking mechanism with an overhead trolley line of an electrical power grid; and an electronic control unit in control communication with the regenerative braking mechanism and the electrically actuated valve in the braking system, and being configured to receive data indicative of a change in demand for regenerated electrical power in the electrical power grid; the electronic control unit being further configured to command braking the mining truck via outputting a control command to the electrically actuated valve such that application of a retarding torque on the ground engaging wheels is allocated from the friction braking mechanism to the regenerative braking mechanism in a manner which is responsive to the data.
