A trailer includes a trailer frame having a hitch. A stationary support base is joined to the trailer frame. Two supports are slidably guided on the support base toward and away from each other. A wheel assembly is mounted to an end of each of the supports remote from the other support such that a distance between the wheel assemblies varies with movement of the supports on the support base. A locking device selectively locks each support to the support base in a first position where the wheel assemblies are furthest from each other and a second position where the wheel assemblies are closer to each other.

A slide-out room system includes a motor-driven sheath with wound cables for extending and retracting the slide-out room. The cables and the sheath are configured such that rotation of the sheath in one direction displaces the cables to extend the room and such that rotation of the sheath in an opposite direction displaces the cables to retract the room.

A mobile generator includes a housing having a top portion, a first side portion, and a second side portion, wherein the first side portion includes an energy-receiving component. The mobile generator also includes an arm pivotally coupled to the housing at a first pivot point and to the first side portion at a second pivot point. A first motion controller is configured to drive rotation of the arm about the first pivot point, and a second motion controller configured to drive rotation of the first side portion about the second pivot point.

The present invention relates to a ramp gate trailer bed extension device capable of expanding the overall length of a trailer bed for transporting larger cargo. The device is designed as a mechanical device and includes two independent flat iron or telescoping rods, each rod is attached to the trailer and the ramp for enabling up and down movement of the gate. In one embodiment, the ramp becomes substantially horizontal and selectively coplanar with trailer bed to expand the overall trailer length to increase cargo carrying capacity to carry longer items. In other embodiments, the ramp is positioned at a 45-degree angle relative to the trailer bed for offering enhanced aerodynamics for reducing drag on the trailer and increasing fuel economy. Each rod has a clip for secured attachment and offers complete utilization of the ramp for carrying long cargo items.

A system to field install solar racking components and torque beams includes a trailer base with structural supports, having independent left and right cantilever axles and a wheel configured to level said base on a horizontal axis a first vertical lift system connected to said base and pivotably connected to a cross brace and a table top rail configured to raise and lower a set of torque beam above beam post to traverse field, and a second vertical lift system connected to said base and connected to said cross brace and top rails position at one end of said cross brace and said table top rail to extract torque beam from said cross brace and a said table top rail to position torque beams relative to beam post.

A housing and trailer system comprising a trailer and a housing. The housing includes a lower housing and an upper housing and may be positioned on friction-reducing members that reduce friction between the housing and trailer. The reduction of friction facilitates the housing to slide more efficiently on the trailer. A safety lever and linkage system operates to safely move roof support structures and raise/lower the upper housing. An adjustable cargo system is attached to a roof on the housing. The adjustable cargo system is adjustable to receive and/or secure different sizes of cargo.

The present invention relates to a transport wagon consisting of a base frame, wherein the base frame comprises a rotatable bogie assembly on its front side for attachment to a powered tow or push truck and comprises one or more front steering wheels placed on the front side of the base frame and one or more rear steering wheels placed on the rear side of the base frame, wherein the one or more front steering wheels and the one or more rear steering wheels are coupled in such a way to the rotatable bogie assembly, that in operation the one or more front steering wheels rotate along with the rotatable bogie assembly and that the one or more rear steering wheels rotate in opposite direction with respect to the rotatable bogie assembly, wherein the base frame comprises at least one longitudinal beam to which a front cross beam, a rear cross beam and at least one intermediate cross beam are arranged with intermediate spaces, wherein at least one intermediate space is arranged for receiving goods, wherein an intermediate wheel suspension with two or more intermediate wheels is arranged under one or more of the intermediate cross beams. The present transport wagon provides a transport wagon that remains well steerable on uneven floors.

A multifunction garden cart, that can carry builders sack, where the cart is comprised of U-shaped chassis built of side rods connected by front rod. The U-shaped chassis is connected to two wheels attached at the center of the side rods. Various types of handles can be connected to the front rod, so it can be moves by a person or attached to a towing vehicle. Two rods pivotally attached to the side rods, can be secured vertically to the plane of the U-shaped chassis. A closed square top frame for use as builders sack support, is removably, pivotally attached at the top of the vertical rods.

A tiltable trailer that can assume a high, or road, position, and a low loading position in which the trailer is tilted with respect to the ground. The trailer includes wheels; a chassis mounted on an axle that pivots with respect to the wheels; an actuator for actuating the pivoting of the axle relative to the wheels to vary the position of the chassis with respect to the ground, the actuator including a flexible element secured to the axle and a tensioner attached to the chassis for adjusting tension of the flexible element; and a lock for locking the trailer in the high position, which is separate from the actuator. The lock includes a sliding locking bar, a first end of which is secured to the axle and a second end of which cooperates with a locking mechanism, mounted on the chassis, when the trailer is in the high position.

Methods, systems, and apparatus, including computer programs encoded on computer storage media, coordinate dynamic adjustments of a trailer based in part on a user profile associated with a user physically present at the trailer and an activity profile associated with an activity selected to be performed at the trailer. A dynamic adjustment may modify a tilt of a lower surface of the trailer. A dynamic adjustment may modify a dimension(s) of the trailer based in part on a detected object(s). Various dynamic adjustments may occur concurrently, individually and/or sequentially. The trailer may be a moveable trailer for temporary attachment with a vehicle.
