A slope mower includes a mower body, drive wheels, left and right mower decks and left and right support wheels mounted on support arms pivotally mounted to the mower body with hydraulic actuators acting on the left and right support arms to maintain the mower body vertical. An inclinometer measures the tilt angle of the mower body and a controller reads the angle and controls a leveling valve to supply hydraulic fluid from a supply line to the leveling actuator toward which the inclinometer indicates the mower body is leaning to move the mower body back to vertical. The system can be programmed to actuate a leveling actuator only when the detected tilt angle exceeds a minimum angle. Lockout valves can be actuated by the controller to block the flow of hydraulic fluid to or from both actuators if a maximum allowed tilt angle is exceeded.

A work machine management apparatus includes: a switchback point setting unit configured to set at least one switchback point of a work machine in a work place of a mine; a work point setting unit configured to set a plurality of work points of the work machine; a travel track generating unit configured to generate, based on a position of each of the plurality of work points and a position of the at least one switchback point in a loading place, a plurality of target travel tracks along which the work machine travels in the work place; and a travel track selecting unit configured to select, among the plurality of target travel tracks, a target travel track along which the work machine travels in the work place.

A self-driven modular sandbagging device applicable to a dump-truck with a truck bed that defines a sand carrying volume, comprising: a replacing tailgate for the truck bed, capable of replacing the original regular tailgate of the dump-truck, at the lower inner end of the replacing tailgate an integral elongated housing is included, in free contact with the carrying volume of the truck bed, in the integral elongated housing an auger is rotatably installed; the auger is driven by a hydraulic motor located inside the housing, a hydraulic pump connected to the hydraulic motor is attached to the external side of the replacing tailgate, at one end of the housing a bag-filler nozzle is included.

A convertible trailer system includes a convertible trailer having a segmented lower deck, and a segmented upper deck mounted thereover. The segmented lower deck includes floating forward and rear belly ramps which are independently actuable relative to each other so as to be selectively raised and lowered relative to a pair of side rails which define the belly forward of the trailer wheels. When in a fully lowered position the belly ramps are lowered to a lower extremity between the pair of side rails so as to be substantially entirely below uppermost edges of the pair of side rails. When in an elevated position the belly ramps are elevated so as to be co-planar with or above the uppermost edges of the side rails whereby freight may be loaded laterally onto the belly ramps over the pair of side rails.

A method and system to control movement of a dump bin for a dump vehicle having a frame. The dump bin is configured to move through a range of angular positions with respect to the frame, wherein the range of angular positions includes a bin down position at one end of the range and a bin up position at the other. An angular sensor generates angular position information throughout the range of angular positions. An automatic calibration is made at the bin down position and at the bin up position to account for changes to the system caused by sensor drift or mechanical deformation of the dump vehicle and its various parts. By continuous adjustment of the bin positions using the calibrated positions, false positives of the bin alarm are reduced, bin height restrictions are avoided, engine derating is reduced, and float mode is more accurately controlled.

A hoist system for hoisting an object onto an all-terrain vehicle having a first vehicle end and a second vehicle end includes a winch configured for mounting on the vehicle at the first vehicle end. A cable may be engaged by the winch. The cable may have sufficient length to extend from the winch over the vehicle beyond the second vehicle end. At least one overhead cable guide assembly may be configured for mounting in upward-standing relationship on the vehicle between the first vehicle end and the second vehicle end. The at least one overhead cable guide assembly may support the cable. An all-terrain vehicle having a hoist system is also disclosed.
