A highway towable dock-lift trailer for use in loading and/or unloading trucks, rail cars, containers, etc., for example, in any location and across all industries and applications, and can include a tow bar that allows the trailer be towed to a desirable position or location. When the tow bar is removed from the trailer or repositioned relative to the frame, either a truck can back into position or the trailer lift can be positioned against the truck, etc., and the trailer lift is then ready to load and/or offload the truck. As an operator elevates the loading platform of the trailer, via hydraulic lifting means, for example, the lift can move up to truck height and hydraulically operated lifting arms can operate opposed automatic folding ramps, which simultaneously can open for load distribution and close for safety. The trailer can include a plurality of screw down or hydraulically actuated jacks to level and secure the platform, and the trailer can include bumpers to absorb the forces from a truck accidentally impacting the trailer.

A trailer for raising and lowering a load including a lifting frame and a base frame configured to secure the load, where a rearward portion of the base frame is rotatably connected at a rear hinge point to the lifting frame. The base frame and the load are raised and lowered based on the tension of a cable attached at one end to the base frame. The tension of the cable is adjusted by a winch attached to the lifting frame. The trailer is configured to allow for an individual operator to raise and lower the load without requiring the assistance of other personnel or facilities.

Provided is a mobile body system including a traveling unit having an autonomous traveling function and a trolley unit having a housing portion for loading an object. A detection unit detects an amount of objects placed on the housing portion. A control unit determines an operation of the traveling unit based on the amount of objects detected by the detection unit.

A photovoltaic (PV) module distribution device may include a platform and an installation arm. The platform may be configured to store a plurality of PV modules in a pre-determined orientation. Each of the PV modules may include solar components that are pre-assembled to form a corresponding PV module. The installation arm may be configured to retrieve a PV module of the plurality of PV modules from the platform. The installation arm may also be configured to position the PV module proximate a support column physically located proximate the PV module distribution device to permit a user to attach the PV module to the support column.

The invention relates to a transporter device (3a) for moving and parking modules (2), each module (2) being devoid of its own traction means, the transporter device being moveable and comprising at least one module gripping means configured to be movable between a gripping position wherein the gripping means extends at least partially under or inside the module, preferably in the bottom sector or via the underneath of the module, and a release position wherein the gripping means does not extend into the module, said gripping means being configured to support the weight of the module (2), the device comprising at least one computer associated with sensors, for controlling the movement of the transporter device (3a) and the gripping means. The device comprises at least one column and at least one upright connected to said column, and is configured to be able to straddle the modules. The invention also relates to a robotic system and a corresponding program.

Improved trailers are disclosed having a lowering system comprising lift arms and swing arms that are operable via a plurality of cables and which allow the improved trailers to be oriented in a raised or lowered position.
