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 mobile bin tipper that is configured to receive, lift, and rotate a bin. The mobile bin tipper quickly and efficiently empty the content of bins into larger containers.

A trailer lift that rises to high levels that may tilt for loading and unloading. The trailer lift includes a lift-and-tilt mechanism, a trailer base, and a trailer platform. The lift-and-tilt mechanism includes a lower-strut link, an upper-strut link, a support member, a lower lift cylinder, and an upper cylinder. The lower-strut link and the upper-strut link are pivotably and terminally attached to each other. The support member is positioned offset to the lower-strut link and is pivotably attached to the upper-strut link to guide the upper-strut link. The trailer platform is terminally and pivotably connected to the upper-strut link. Similarly, the trailer base is pivotably and terminally connected to the lower-strut link and the support member. The upper lift cylinder is pivotably mounted in between the upper-strut link and the trailer platform. The lower lift cylinder is pivotably mounted between the upper-strut link and the lower-strut link.

A suspension system for a vehicle includes an extendable and retractable actuator disposed at each side of a frame of the vehicle and pivotally attached at one end to a vehicle bracket and at the other end to a suspension bracket. The suspension bracket includes an actuator portion, an axle portion and a suspension arm, with the actuator portion and the suspension arm pivotable relative to an axis of the axle portion. When the actuator is extended or retracted, the actuator portion pivots about the axis of the axle portion and imparts pivotal movement of a suspension arm about the axis to adjust a height of the frame of the vehicle. The actuator includes an elastomeric element disposed between an outer end of a slide rod and an outer end of a ram rod, with the slide rod movable to absorb sudden movements of the frame or wheel.

There is disclosed a method of determining the mass of a load in a tipper body of a tipper, the tipper includes a tipper body pivotably moveable with respect to a frame with a hydraulic cylinder disposed therebetween and actuatable to pivot the tipper body. The method includes receiving at least one pressure parameter relating to the hydraulic pressure within the hydraulic cylinder at an angular position of the tipper body and at least one angular positional parameter relating to the angular position of the tipper body at the angular position; and determining a mass parameter relating to the mass of a load in the tipper body based on at least the at least one pressure parameter and the at least one angular positional parameter.

A method for paving wherein the paving operator or a person in the vicinity of the paver remotely controls the flow of paving material from a dump truck into the hopper of the paver.

A dumping vehicle includes a vehicle elevation system for elevating a body of a vehicle. The system can use one or more components of a vehicle as a main support against which a vehicle body is elevated. In certain examples, a suspension device of the vehicle can be used as the main support. The system further includes an elevation device arranged between the suspension device and a vehicle frame and configured to elevate the vehicle body by lifting the vehicle frame against the suspension device.

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 conveyance vehicle, and a work machine that loads materials onto the conveyance vehicle. A first processor of a work machine determines a target stop position of a conveyance vehicle based on a position of the work machine, a target offset distance, and the direction of the loading position. A second processor of the conveyance vehicle acquires data indicative of the target stop position of the conveyance vehicle from the work machine. The second processor controls the conveyance vehicle to move the conveyance vehicle to the target stop position.

A haulage vehicle includes a vessel 3, hoist cylinders 10, a control valve device 16 that controls a supply or discharge of pressurized oil to or from the hoist cylinders 10, a controller 35, and a tilt angle detector 31 that detects a tilt angle of the vessel 3. The controller 35 compares a down assist performing angle, which is a tilt angle preset to determine whether negative pressure control processing needs to be performed for offsetting a force applied in a direction that would cause the hoist cylinders 10 to extend, with the detected tilt angle and, if the detected tilt angle is determined to be equal to or greater than the down assist performing angle, outputs a control valve signal to the control valve device 16 so that the valve is opened to forcibly discharge pressurized oil from the hoist cylinders 10.
