Abstract: 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.

Abstract: A system includes a support, a sensor coupled to the support and arranged to output signals in a direction towards a haul road on which a machine traverses, an indicator coupled to the support, a first line coupled to the support, and a second line coupled to the support. Sensor data is received from the sensor, and based on the sensor data, a position of the machine on the haul road is determined. An alignment of the machine on the haul road is determined, where the alignment is associated with the machine maintaining contact with the first line and the second line. An indication is displayed for laterally aligning the machine on the haul road.

Abstract: A mounting structure for supporting one or more pantographs in a machine is disclosed. The mounting structure includes a bottom support structure and a middle support structure removably mounted on the bottom support structure. The middle support structure includes a pair of secondary front legs removably coupled to the pair of primary front legs. The middle support structure includes reinforcement members for removably connecting the top portion of one of a secondary front leg and a rear leg with a deck. The mounting structure includes a top platform removably mounted on the middle support structure for supporting the pantographs. The top platform includes a first supporting member and a second supporting member. Each of the first supporting member and the second supporting member is supported along a first side arm and a second side arm of the deck, respectively.

Abstract: A ventilation system for a machine including an engine, an engine compartment having an interior, a secondary compartment having an interior, and a sensor. The ventilation system has a ventilation fan having a fan outlet, and a duct configured to direct air from the fan outlet to at least two of the interior of the engine compartment, the interior of the secondary compartment, and the sensor.

Abstract: An electrical connector has a base with a row of conductor openings through the base and a slotted plug socket in one base side parallel to the row. A plug has conductive surfaces and is insertable into the socket to wedge conductors against the conductive surfaces. Conductor grooves are provided in the socket at positions matching the conductive surfaces.

Abstract: A detonator has a transparent polycarbonate tubular casing, with an electric igniter inserted from one end to abut a constriction in the tube. The conflagration charge is deposited onto the igniter from the other tube end, and primary and secondary explosive charges respectively are added from that other end.
