Provided is a work vehicle that can be transported by being loaded onto a trailer without having the outriggers removed. The work vehicle (rough terrain crane) is transported by being loaded onto a low bed trailer including a low bed and a high portion (first high bed, second high bed) higher than the low bed in at least one of the front and the rear of the low bed, and includes: outrigger units (front outrigger unit, rear outrigger unit) that are mounted to the front and rear of a vehicle body; and a lift unit that lifts and lowers the outrigger units (front outrigger unit, rear outrigger unit with respect to the vehicle body.

A wheeled engineering vehicle includes a frame; a first telescopic cylinder disposed on the frame; and a stabilizer assembly connected with the first telescopic cylinder and configured to rotate relative to the frame under drive of the first telescopic cylinder. The stabilizer assembly includes: a first stabilizer leg having a hollow structure; a second telescopic cylinder disposed in the first stabilizer leg; a second stabilizer leg configured to extend or retract relative to the first stabilizer leg under drive of the second telescopic cylinder, and the first stabilizer leg configured to radially limit the second stabilizer leg; and a stabilizer foot connected to the second end of the second stabilizer leg and configured to be in contact with the ground to support the vehicle. The first stabilizer leg, the second stabilizer leg and the stabilizer foot cooperate to support the whole vehicle to improve the stability of the vehicle.

A vehicle jacking assembly includes a plurality of lifting units that is each coupled to a bottom side of a vehicle. Each of the lifting units is actuatable into an extended position to lift a respective tire upwardly from the support surface. A pump is coupled to the vehicle and each of the lifting units is fluidly coupled to the pump. The pump urges a hydraulic fluid into or out of the hydraulic piston of a respective one of the lifting units when the pump is actuated into a lifting condition or a lowering condition. A control is positioned within the vehicle to actuate the pump to urge the hydraulic fluid into a respective one of the lifting units based upon the driver's preference. In this way the respective tire can be lifted from the ground without requiring the driver to manually jack the vehicle.

A trailer system with a modular design is provided for the transport of tiny homes. The system comprises a front hitch assembly to connect to a suitable towing or transport vehicle, and a rear axle assembly designed to carry the weight of a tiny home. The trailer bed portion of the trailer system is the tiny house foundation adapted to connect with the front hitch and rear axle assemblies in a lowboy configuration. Each of the front hitch and rear axle assemblies have pegs that can be secured into channels formed into the end walls (e.g. slots/cavities) or alongside walls (e.g. grooves) of the foundation. Once inserted into the channels, the pegs can be secured to the foundation using a securing means (e.g. locking pins). After transport of the tiny home, the front hitch and rear axle assemblies can be connected to each for transport to another location.

An integrated vehicle jacking assembly includes a plurality of jacks that is each coupled to a bottom side of a vehicle. Each of the jacks is actuatable into an extended position for lifting a respective driver's side or passenger's side of the vehicle upwardly thereby facilitating tires on the respective driver's side or passenger's side of the vehicle to be removed and replaced. A control unit is positioned within the vehicle and the control unit is operationally coupled to each of the jacks. The control unit actuates one or both of the jacks between the extended position and the retracted position. A plurality of wheel chocks is provided for inhibiting the vehicle from rolling when the vehicle is lifted.

A vehicle jacking assembly for raising a vehicle includes a plurality of cylinders, each of which is configured to couple to a frame of a vehicle proximate to a respective wheel of the vehicle. The cylinder comprises a plurality of nested sections so that the cylinder is selectively extensible. An actuator that is coupled to the vehicle is operationally coupled to the plurality of cylinders and an electrical circuit of the vehicle. The actuator is positioned to selectively actuate the plurality of cylinders to extend the cylinders from the frame of the vehicle so that the cylinders contact a surface. The plurality of cylinders thus is configured to raise the vehicle.
