    摘要: In some implementations, a battery manager may identify a first voltage rating of a first battery pack. The battery manager may configure, based on the first voltage rating, a resistor bank of the battery manager to have a first resistance value. The battery manager may perform, via the resistor bank having the first resistance value, a first discharge operation, associated with the first battery pack, having a first duration. The battery manager may identify a second voltage rating of a second battery pack. The battery manager may configure, based on the second voltage rating, the resistor bank of the battery manager to have a second resistance value. The battery manager may perform, via the resistor bank having the second resistance value, a second discharge operation, associated with the second battery pack, having a second duration, and a difference between the first duration and the second duration satisfying a time threshold.

    摘要: A hydraulically operated breakout (“HOBO”) wrench is disclosed herein. The HOBO wrench comprises: a pedestal, a swing arm pivotably mounted to the pedestal having a first cylinder and a second cylinder, a fixed jaw connected to the swing arm and having a third cylinder, a clamping jaw configured to engage a plurality of fasteners and a plurality of rods, a plurality of proximity sensors, and a HOBO controller in communication with the plurality of proximity sensors. The HOBO controller is configured to actuate the HOBO wrench to and from a parked position, an engaged position, and a clamping position. The plurality of proximity sensors communicate signals to the HOBO controller to maintain a threshold clearance between the HOBO wrench and other components when moving to and from the parked position, the engaged position, and the clamping position.

    摘要: A service vehicle can have a service vehicle battery that can provide energy to, and/or receive energy from, a separate machine that is normally configured to operate based on energy provided by a battery of the machine. If a machine becomes unable to operate using the battery of the machine, the service vehicle can travel to the machine and use an energy transfer arm to transfer energy to the machine. In some situations, the service vehicle and the machine can travel together in a convoy formation, for instance to a maintenance station, while the service vehicle provides the machine with energy for driving operations of the machine.

    摘要: A ground engaging tip of a ground engaging tip assembly includes an adapter configured for attachment to the base edge of the implement and having a forwardly extending adapter nose. The ground engaging tip has a rear edge, a top outer surface, and a bottom outer surface. The top and bottom outer surfaces extend forward from the rear edge and converge at a front edge of the ground engaging tip. The tip has first and second side outer surfaces extending forward from the rear edge of the ground engaging tip to the front edge. The tip has a nose cavity for receiving the adapter nose therein. The tip has a support rib on at least one of the first or second side outer surfaces, the support rib being positioned at the rear edge and extending lengthwise from the bottom outer surface toward the top outer surface.

    摘要: The present invention pertains to a wear pad assembly for adjusting a position of a wear pad in a telescopic boom of a work machine, comprising a threaded boss, a threaded bolt configured for threaded engagement with the threaded boss and a wear pad connectable to the threaded bolt. The wear pad assembly further comprises locking means configured to lock the threaded boss and the threaded bolt in a first engagement position and at least a further engagement position. The present invention further pertains to a method of adjusting such a wear pad assembly, the wear pad assembly being mounted to a first telescopic boom segment such that the wear pad provides a sliding surface for a second telescopic boom segment, the method comprising the steps of unlocking the threaded bolt by disassembling at least a part of the locking means, rotating the threaded bolt from the first engagement position into the further engagement position, and locking the threaded bolt in the further engagement position by reassembling the disassembled locking means when the threaded bolt is in the further engagement position.

    摘要: The top cover defines a first fastener receiving void that is disposed along the direction of material flow between the forward ramp portion and the rear edge. The top male angled surface of the top cover defines a first material flow groove that extends along the direction of material flow, and includes a first flow ramp. The first material flow groove is disposed adjacent along the lateral direction and the direction of material flow to the first fastener receiving void.

    摘要: A diffuser for a return line on a hydraulic tank may include a coupling portion configured for coupling in fluid communication with a return port of the hydraulic tank and for receiving return fluid along an incoming longitudinal direction. The diffuser may also include a dispersion portion in fluid communication with the coupling portion and configured for dispersing the return fluid radially. The diffuser may also include a manifold arranged around the dispersion portion and configured to direct the return fluid circumferentially and axially.

    摘要: Operating a fuel system for an engine includes moving a plunger during a pumping cycle between an advanced position and a retracted position, and pulsing a solenoid actuator in an electrical circuit during at least one off cycle of the plunger where the plunger is neither advancing nor retracting with a plurality of current pulses of varied duration. An electrical property such as a freewheeling response in the electrical circuit induced by moving a valve in response to each respective current pulse is monitored, and a valve timing of the valve determined based on the monitored electrical property. The fuel system including a fuel injector may be electronically trimmed based on the determined valve timing. Related apparatus and control logic is also disclosed.
