摘要： A system for monitoring electrical contacts for an overhead trolley line may include a wear sensor arranged such that an electrical contact on a vehicle or work machine for contacting the overhead trolley line is continually or periodically in its line of sight. The wear sensor may be configured to capture spatial data defining the surface profile of the electrical contact. The system may also include a data processing module configured to receive the spatial data and identify a defect in the electrical contact based on the spatial data.

摘要： A lock assembly for attaching a wear member to a base includes a retaining block with a spring attached to the retaining block that fits into an aperture of the base. A lock pin fits into the aperture of the wear member, and the aperture of the retaining block, retaining the wear member onto the base. The lock pin engages the spring that prevents unintentional rotation of the lock pin so that the lock pin is trapped in the aperture of the wear member, preventing its unintentional removal.

摘要： A lock includes a drive portion and a pin receiving portion. The drive portion includes a polygonal aperture, and the pin receiving portion includes a hole with an internal surface of revolution that defines an axis of rotation, a radial direction, a circumferential direction, and a slot extending at least partially through the pin receiving portion into the hole.

摘要： A work implement for a construction machine includes a collection member, a first side wall, a second side wall, and a plate member coupled to the collection member, the first side wall, and the second side wall. The collection member, the first side wall, the second side wall, and the plate member together define a hollow space. Further, at least one of the first side wall, the second side wall, and the plate member define an opening that communicates with the hollow space. The work implement further includes a sensor mounting system including a cover, a plurality of mechanical fasteners adapted to couple the cover with the work implement, and a sensor mounted on the cover. Upon coupling of the cover with the first side wall, the sensor is partially received within the hollow space.

摘要： A generator set configured to provide an electrical output to an external electrical load. The generator set includes an engine configured to drive an electric generator, the engine including an engine block, where the electric generator is configured to couple to the external electrical load. The generator set includes a heating system in fluid communication with the engine block, the heating system including an electric fluid heater, where the electric jacket fluid includes a resistive load configured to supplement the external electrical load. The generator set includes a control system for: monitoring a first parameter of the engine; generating a first control signal in response to the first parameter being less than a first threshold; and increasing the external electrical load by turning on the electric fluid heater in response to the first control signal.

摘要： A retainer sleeve includes an at least partially annular body defining an axis of rotation, a radial direction, and a circumferential direction. The body may also have a radially inner annular surface defining a radially inner aperture, and a first anti-rotation feature extending radially inwardly from the radially inner annular surface including a sloping ledge having a locking surface, and an outer peripheral surface defining a notch that is at least partially aligned with the first anti-rotation feature or an array of a plurality of external ribs extending outwardly radially from the outer peripheral surface.

摘要： A boom, of a machine, may include a first member; a second member opposite the first member; and a support structure. The support structure may comprise a first support member; a second support member; and a third support member. The first member, the first support member, and the second support member may define a first opening. The second member, the second support member, and the third support member may define a second opening. A first area of the first opening may exceed a second area of the second opening.

摘要： A driving circuit to control/drive a contactor using a high-side driver integrated into the battery pack controller. The driver circuit may electrically isolate the controller pins of the battery pack controller (which interface the contactors) from the low-voltage digital processing core of the battery pack controller. The driver circuit may provide techniques to diagnose a fault by monitoring the voltage at the output of the driver as compared to the reference voltage. The driver circuit may include an electronic switch, such as a field-effect transistor, that is configured on the high side of the contactor to control voltage from an energy source to the contactor.

摘要： A method for asset identification string error detection can include receiving an asset identification string corresponding to an asset and aggregating data associated with the asset from multiple sources. The method can include creating one or more probabilistic tables linking the aggregated data to the asset and determining a likelihood that at least a portion of the asset identification string is correct based on the probabilistic tables. The method can indicate that the asset identification string includes an error when the likelihood is less than a selected threshold and otherwise indicate that the asset identification string is correct when the likelihood is greater than or equal to the selected threshold.
