A control method for a cleaning system, comprising the following steps: first control step—controlling a transfer robot to move a cleaning robot to a cleaning area; cleaning control step—controlling the cleaning robot to perform a cleaning operation on a upper surface of the cleaning area; second control step—controlling a transfer robot to move the cleaning robot away from the cleaning area.

In one aspect there is provided a trailer having a front end, a rear end and a loading deck for carrying a skidsteer having an implement connector frame. The trailer further comprising a carrier operable to receive the skidsteer's implement connector frame. In a system aspect, there is provided trailer and skidsteer system. The trailer has a front end, a rear end and a loading deck for carrying a skidsteer thereon. The skidsteer has an implement connector frame. The system comprises a carrier operable to receive the skidsteer's implement connector frame and securing means to secure the implement connector to the carrier member. When the implement connector is secured to the carrier member, using the securing means, the skidsteer is placed in a secured transport position on the loading deck.

Vehicle bed loading ramp systems are disclosed. Systems include (a) a first section comprising a rigid framework defining a pair of ramps, the first section having first outer edges extending parallel to the ramps; (b) a second section comprising a rigid framework defining a pair of ramps, the second section having second outer edges extending parallel to the ramps; (c) at least one wheel mounted adjacent each of the first outer edges; and (d) a pair of locking hinge assemblies mounted to extend between one of the first outer edges and an adjacent one of the second outer edges to provide a hinged coupling between the first section and the second section. When the locking hinge assemblies are locked open the ramps of the first and second sections are colinearly arranged and capable of supporting the weight of an off-road vehicle to be loaded without collapsing.

A system for moving a work machine includes a towing vehicle, a trailer arranged to be towed with the towing vehicle, and a towing arrangement for the towing vehicle. The towing vehicle includes a towing vehicle's towing point arranged under its chassis between the front axle and rear axle. The trailer includes a chassis and a towing arm, a deck, and wheels. The towing arrangement includes: a drawbar having a first end pivoted to the towing vehicle's towing point and a second end having a drawbar's towing point for the trailer to be towed, a first pivot under the rear axle and in a transverse direction of the vehicle chassis for pivoting the drawbar to the towing vehicle's towing point, a second pivot having a vertical axis and being fitted to the drawbar's second end to transmit a load of the trailer being towed rigidly to the first pivot, a third pivot, located at one end of the drawbar, to permit the trailer to tilt in a transverse direction of the towing vehicle, a vertical support for the second pivot, an upper drawbar, and a connector arm, wherein the drawbar, the upper drawbar, and the connector arm form a closed structure around the rear axle.

A heavy vehicle and machinery trailer having: (i) a trailer base with wheels and suspension; (ii) a trailer bed supported on the trailer base by the suspension; (iii) loading ramps connected to the trailer bed where the suspension, or other methods such as hydraulically operated landing legs, are adapted to allow an operator to alter the pitch and/or roll angle of the trailer bed relative to the ground surface and wherein where the loading ramps are adapted to have varying lengths such that the ramps can be evenly pitched when they are extended to the ground on a sloped surface. The trailer has a hydraulic system under the control of an electrical controller which is operated by a user. The electrical controller has a preset matrix of safe loading and unloading parameters which it uses to determine whether the sensed state of the trailer is safe for loading or unloading.

A securing system for securing an item of plant machinery to a trailer comprises a retainer disposed in a forward region of the trailer, the retainer comprising a recess for receiving a part of a dozer blade of said plant machinery, and the retainer being configured such that movement of a dozer blade engaged with the recess is restricted in forwards, rearwards and upwards directions relative to a floor of the trailer.

There is provided a first vehicle shaped to be received on a cargo bed of a second vehicle. The first vehicle includes at least one rear light. The first vehicle includes a wiring harness coupled to the rear light of the first vehicle. The wiring harness is connectable to at least one electrically-powered rear light of the second vehicle so as to be powered therefrom and to function in concert therewith.

A shovel includes a lower-traveling structure; an upper turning structure which is turnably mounted to the lower traveling structure; and a processing circuitry provided in the upper turning structure, wherein the processing circuitry is configured to, upon receipt of a predetermined command from a predetermined external device, cause the lower-traveling structure to travel either toward a bed of a trailer or from the bed to a rear area of the trailer. A support device configured to support a shovel in loading or unloading a trailer, the support device includes a transmitter configured to transmit, to the shovel, a command for an automatic traveling of the shovel in response to a user's operation so that a lower-traveling structure of the shovel travels from a rear of the trailer to an upper surface of the trailer, or travels from the upper surface of the trailer to the rear of the trailer.

A transport trailer includes an elongated body having spaced vertical supports for vertical actuators, a lower deck extending along and supported by the elongated body, and an upper deck supported by the vertical actuators. The upper deck is movable along the vertical supports via the vertical actuators. The upper deck can be lowered to a position to be substantially superimposed on top of the lower deck by the vertical actuators.

This specification describes systems for unmanned vehicle carrying and deployment. In some examples, a system includes a deployable robot including at least one rotatable flipper disposed on a surface of the deployable robot. The system includes a base unmanned vehicle configured for carrying and deploying the deployable robot. The base unmanned vehicle includes a base robot chassis, and the base robot chassis includes a platform for securing the deployable robot and at least one retention bracket disposed on the platform. The flipper is configured to rotate in a first rotational direction to lock the deployable robot onto the base robot chassis by engaging with the retention bracket.
