Abstract: A method of controlling a digging operation of an industrial machine. The industrial machine includes a dipper connected to a dipper handle, a hoist rope attached to the dipper, and a hoist motor moving the hoist rope and the dipper. The method includes determining that the dipper is ready to be unloaded, activating a secondary tipping control operation by controlling a speed of the hoist motor, controlling an acceleration ramp rate of the hoist motor, and controlling a deceleration ramp rate of the hoist motor. The method further includes determining when the dipper is unloaded and deactivating the secondary tipping control operation.

Abstract: A spring assembly for a latch mechanism includes a spring, a first support, and a second support. The spring includes a first end, a second end, and a plurality of coils extending therebetween. The coils define an internal helical surface. The first support is configured to be coupled to a first pivoting member. The first support includes a grooved surface for threadingly engaging at least a portion of the internal helical surface of the spring proximate the first end. The second support is configured to be coupled to a second pivoting member. The second support includes a grooved surface for threadingly engaging at least a portion of the internal helical surface of the spring proximate the second end.
