A process for execution by a processor of an electronic control unit (ECU), comprising: (a) detecting an operator command to align an upper structure of a tracked vehicle relative to a lower structure of the tracked vehicle; (b) in response to detection of the operator command, applying controlled rotation of the upper structure relative to the lower structure about an axis to align the upper structure relative to the lower structure at a predetermined relative angle; (c) in response to the upper structure having been aligned relative to the lower structure at the predetermined relative angle, signaling that alignment has been achieved; and (d) causing rotation of the upper structure to stop when alignment has been achieved and being non-responsive to further detection of the operator command during and for a predetermined period of time after said signaling. Also, a tracked vehicle comprising an ECU that executes the above process.

A hydraulic tank for a machine is disclosed herein. The hydraulic tank includes a casing defining an interior space and having an outer surface, an inner surface opposite the inner surface, and a return hydraulic fluid inlet extending through the casing. A first concave member is connected to the inner surface of the casing to form a passage. The passage is positioned and shaped to transport hydraulic fluid from the return hydraulic fluid inlet to another location within the hydraulic tank.

A trailer system for hauling material. The trailer system including a frame and a container attached to the frame. A lid is operatively associated with a first aperture and adapted to at least move between an open position and a closed position. When in the closed position the lid seals the first aperture such that the seal is watertight. A gate is operatively associated with a second aperture and adapted to at least move between an open position and a closed position. When in the closed position the gate seals the second aperture such that the seal is watertight. A pusher plate assembly is arranged with the container for pushing material contained in the container in a direction towards the second aperture.

A power unit with manual override control for a hydraulic system having an initial state and at least one operational state is provided, comprising: a tank for storing hydraulic fluid that moves between a first chamber and a second chamber of a hydraulic cylinder; a pump that routes the hydraulic fluid in and out of the tank; a first relief valve; a first solenoid valve configured to shift between a plurality of positions based on the at least one operational state of the hydraulic system; a first check valve connected to the first solenoid valve; a manual override control unit comprising: a second check valve; and a second solenoid valve configured to shift between a plurality of positions based on activation of a manual override control, wherein the activation of the manual override control returns the hydraulic system from the at least one operational state to the initial state.

A system includes a trailer frame, a lifting mechanism coupled to the trailer frame, wherein the lifting mechanism is configured to raise or lower a coil of pipe or a reel of pipe, a braking mechanism configured to apply pressure to the pipe while the pipe is being deployed by the system, and a hydraulic power unit configured to hydraulically power the system.

A hoist valve assembly for a work machine cylinder includes a main control valve, a counterbalance valve and a counterbalance shutoff valve. A main control valve raise position connects a head end of the cylinder with a pressurized fluid source and a rod end of the cylinder to a low pressure reservoir to extend the cylinder. The counterbalance valve is between the rod end and the main control valve, is biased to a closed position and has an open position connecting the rod end to the low pressure reservoir. Rod end and head end pressure signals apply force to the counterbalance valve toward the open position. The counterbalance shutoff valve is positioned between the head end and the counterbalance valve, and has a normal position to apply the head end pressure signal to the counterbalance valve and a shutoff position that blocks the head end pressure signal from the counterbalance valve.

A trailer includes a metal frame, a first dump bed coupled to the frame substantially near a forward end of the frame, and a second dump bed coupled to the frame substantially near a rearward end of the frame. In an embodiment, the first dump bed is a side-dumping dump bed and the second dump bed is a rear-dumping dump bed.

A cylinder propping system includes a sleeve and a locking member. The sleeve includes an outer wall that defines an inner cavity and a ledge. The inner cavity is sized to receive at least a portion of a cylinder assembly therein. A first end of the outer wall is configured to hingedly couple to one end of the cylinder assembly. The ledge is spaced apart from the first end. The locking member is sized to engage with the ledge, between the ledge and a cylinder housing of the cylinder assembly, to prevent movement of the cylinder housing in at least one direction along a central axis of the sleeve.

The transport vehicle includes a first assembly that includes a first lifting frame having a portion that at least partially raises from the main frame and a first bin connected to the first lifting frame. The first bin is configured to be raised from the main frame. The transport vehicle includes a second assembly that includes a second lifting frame that has a portion that at least partially raises from the main frame. The second assembly includes a second bin connected to the second lifting frame. The second bin is configured to be raised from the main frame. The transport vehicle includes a hydraulic system in communication with the first and second assemblies. The hydraulic system allows operation of only one of the first and second assemblies at a time.

The vehicle can have an engine and a moveable lift gate, a power unit driving the movement of the lift gate, the power unit including an electric motor and a capacitor pack, the capacitor pack being connected for powering the electrical motor, and being connectable to a DC alternator source of the engine.
