A canopy of a dump body for a truck comprises a deck having a length and a width greater in dimension that the length defined by a front edge, a rear edge opposite the front edge, a first side edge, and a second side edge opposite the first side edge. The deck can define an upper surface and a lower surface opposite the upper surface. In a front view the deck can define a concave shape, with a center portion and stepped portions between the center portion and the first and second side edges.

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 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.

A rotatable tailgate assembly is provided for installation on a dump bed. The tailgate assembly has support members attachable to the side of the dump bed. Each support member has at least one bearing adjacent at a free end extending rearwardly of the dump bed's rear opening. A tailgate has a cylindrical tailgate shaft with a first end rotatably received within the bearing of a first support member and a second end rotatably received within a bearing of a second support member. The tailgate has a closure portion extending radially away from the tailgate shaft. The closure portion engages the rear edges of the dump bed floor and sides to close off the dump bed opening when the tailgate assembly is in a closed rotational position. The tailgate assembly also comprises a rotation actuator operatively connected to the tailgate shaft for selective rotation thereof.

A work implement tilt control system for a tracked vehicle having a frame and a work implement mounted to the frame, the system comprising: a lifting unit configured to controllably raise or lower at least part of the work implement; an input device actionable by a first and second types of external actions associated with raising or lowering of the work implement; and a vehicle computer configured to send a signal to the lifting unit to carry out a lowering cycle of the work implement in case the vehicle computer determines that a set of conditions has been met. In some cases, the set of conditions includes: (i) a movement characteristic of the tracked vehicle exceeds a threshold; and (ii) the input device has been actioned by the first type of external action since carrying out the most recent lowering cycle of the work implement.

A rocker support insert for a support rocker comprises a support plate configured to be removably coupled to a top portion of a rocker body; and a support padding fixedly coupled to a top surface of the support plate such that a portion of the top surface of the support plate remains exposed. A top surface of the support padding can define a concave upward-facing contact surface, and the support padding can be thicker than the support plate.

A material type identifier identifies a type of material loaded into a dump truck. When the dump truck is unloaded, a flow rate identification system identifies a flow rate of material exiting the dump truck. A flow rate controller automatically controls the tailgate actuator based on a desired flow rate of material exiting the dump body of the dump truck.

A trailer is provided with a frame to connect to an off-road vehicle. A body is pivotally connected relative to the frame and includes a bed and a side panel extending transversely from the bed to define a cargo area. A pitch actuator assembly is coupled between the frame and the body to pivot the body between a storage position and an elevated position. A bracket is connected to a rearward end of the side panel. A tailgate is pivotally connected to a lower portion of the bracket about a first horizontal axis to adjust between a closed position and an open-downward position, and pivotally connected to an upper portion of the bracket about a second horizontal axis to adjust between the closed position and an open-upward position.

A unified hinge may comprise a hinge tube that is rigidly attached to a truck frame and a bed section of a truck bed and a tail section of the truck bed, each of the bed section and the tail section having opposing hinge barrels affixed thereto that concentrically align on the hinge tube. Similarly, a unified hinge may comprise one or more mounting barrels that are rigidly attached to a truck frame and a bed section of a truck bed and a tail section of the truck bed, each of the bed section and the tail section having opposing hinge barrels affixed thereto that concentrically align on the one or more mounting barrels; a hinge tube runs through the one or more mounting barrels and the opposing hinge barrels. The unified hinge allows the bed section and the tail section to independently pivot along the hinge tube.
