Disclosed is a mobile articulated crane having a boom for carrying a load when the crane is stationary and while the crane is mobile. The boom has an end for engaging with a load and an opposed end. The crane further comprises a counterweight attached to the boom at or close to the opposed end of the boom. A rear body of the crane can comprise first and second rear axles, each for supporting the rear body on the ground. The first rear axle can be arranged to be displaced relative to the second rear axle such that wheels of the first rear axle selectively engage or disengage with the ground.

Systems and apparatuses include a tag axle system including an axle assembly, a linkage coupling the axle assembly to a vehicle chassis, and a hydraulic cylinder coupled between the vehicle chassis and the axle assembly. The hydraulic cylinder actuates the axle assembly between a raised position and a lowered position, and acts as a spring damper suspension component.

A crane, in particular a pick and carry crane, may have a front chassis with front wheels and a back chassis with back wheels, the front chassis being articulated relative to the back chassis so that the crane can travel whilst carrying a load suspended from a boom. The back and front wheels have independent suspensions which are capable of connection to one another so that movement of a left wheel influences movement of a right wheel, thereby improving the handing of the crane, particularly over rough terrain.

The disclosure provides an electric utility vehicle with detachable platform. The electric utility vehicle may include a load platform supported on a chassis including at least two electrically driven wheels. The detachable platform may be removeably coupled to the load platform. The detachable platform may include a central hub including a top surface. The detachable platform may include three legs coupled to the central hub, each leg including an actuator configured to extend the respective leg to a ground surface while the detachable platform is coupled to the load platform. The detachable platform may include a controller configured to coordinate the actuators to control an orientation of the top surface.

A suspension system is provided comprising at least one ride height valve, when engaged, that allows an air flow to engage a hydraulic control valve such that it initiates either extension or retraction of a hydraulic piston from a cylinder. Extension or retraction of the hydraulic piston causes a booster frame to be bias downwardly or upwardly, respectively. The ride height valve is engaged when a booster axle is at a predetermined distance from the frame.

Disclosed herein is an adjustable suspension mount system that includes a subframe for attachment to a suspension device of a vehicle. The system further includes a first and second mount link for attaching the subframe to a frame of a vehicle. A positioning device for attaching to the frame of the vehicle and the subframe is also included. The adjustable suspension mount system may also attach to a second suspension device of the vehicle as well as other further suspension devices. Further disclosed is a vehicle having the adjustable suspension mount system, a kit for providing the adjustable suspension mount system, and methods of using the adjustable suspension mount system for raising and lowering a vehicle.

The disclosure provides an electric utility vehicle with detachable platform. The electric utility vehicle may include a load platform supported on a chassis including at least two electrically driven wheels. The detachable platform may be removeably coupled to the load platform. The detachable platform may include a central hub including a top surface. The detachable platform may include three legs coupled to the central hub, each leg including an actuator configured to extend the respective leg to a ground surface while the detachable platform is coupled to the load platform. The detachable platform may include a controller configured to coordinate the actuators to control an orientation of the top surface.

A method and apparatus for lowering the height of a wheeled vehicle for cargo height constraints during transportation. The rear leaf spring shackle on each side of the vehicle is connected to a sliding frame mount. In the transport configuration, fasteners are removed from the sliding frame mount, and the mount slides forward, rotating the rear leaf spring shackle from a near vertical to a near horizontal position, effectively lowering the height of the vehicle. To return the vehicle to the ride configuration, a screw jack member is attached to the sliding frame mount and a rear attachment point on the vehicle, pulling the sliding frame mount back, aligning attachment points of the mount with the frame member in the original position. The fasteners are reinstalled to lock the sliding frame mount into the ride configuration.

Systems and apparatuses include a tag axle system including an axle assembly, a linkage coupling the axle assembly to a vehicle chassis, and a hydraulic cylinder coupled between the vehicle chassis and the axle assembly. The hydraulic cylinder actuates the axle assembly between a raised position and a lowered position, and acts as a spring damper suspension component.

A retractable wheel and/or track drive assembly for an amphibian comprising an actuator, a retraction linkage assembly movable between a protracted position and a retracted position, a suspension assembly at least partially connected to the retraction linkage assembly and movable between a protracted position and a retracted position, and at least one wheel and/or track drive, wherein when the retraction linkage assembly and the suspension assembly are protracted then the retraction linkage and/or suspension assembly supports and/or holds at least one wheel and/or track drive in a ground engaging position for use on land.
