The system may also have a ladder support member adapted to selectively receive a portion of the support flange therein. The system may also have a pivot bracket pivotally connected to the ladder support member. The pivot bracket may be adapted to selectively move the ladder support member.

Abstract: A loading device for incorporation into a vehicle, such as an ambulance, for loading and unloading a stretcher. The loading device has a retracted configuration and an extended configuration. The loading device being predisposed to the extended configuration. The loading device may include a hoist assembly to counteract the predisposition to the extended position and move the loading device to the retracted configuration.

Abstract: In order to save physical power and avoid using manual operative mechanism for unload/reload ladders from/onto a vehicle roof, a electric motor driven ladder rack system has been designed which includes: a fixed guide which is mounted on a vehicle roof; a pivotal guide that is pivotally coupled to the fixed guide; a driving box and a sliding ladder rack which is linked to the driving box by chain and engaged with the pivotal guide. Under acting force of motor and gravity the ladder rack moves sliding backward and pivoting downward from the horizontal position on the vehicle roof to a generally vertical position behind the vehicle at which the ladders can be unloaded/loaded. In an opposite process the ladder rack is pulled back on the vehicle roof. In these processes there is no physical power needed at all.

Abstract: A container handling system and method for a wheeled transport vehicle is disclosed that is capable of loading and unloading containers, particularly in locations where the overhead height is limited. A hinged tail member at the rear end of the elongated body (a/k/a tilt frame member) is rotated to the ground allowing the containers to be loaded and unloaded without rotating the tilt frame to its maximum height. A cable reeving arrangement, such as a dual reeving arrangement, can be utilized to load and unload the container.

Abstract: A ramp stored under the deck of a rail car may be extended using a load-bearing drive system for the loading of freight or equipment onto the rail car. The surface of the ramp may comprise a rail portion or similar structure to allow the loading of rail bound equipment, such as rail maintenance equipment, onto the deck of the rail car.

Abstract: A system has a boat trailer and a mechanical arm coupled to the boat trailer. The system further has logic that actuates the mechanical arm based upon a user input, such that the mechanical arm applies a pressure to the boat when the boat is positioned for loading onto the trailer.

Abstract: The invention concerns a tractor comprising a front frame (1) and a rear frame (5) linked together by a hinge (7) with a vertical pivot and by a power cylinder for the steering of the tractor. In the tractor of the invention, the rear frame (5) consists of an interior body (9) and an exterior body (10) which are telescopically movable relative to each other using a power cylinder (8), the exterior body being provided with a tipping device (11) and a power cylinder (12) for the tipping of a platform placed on the tipping device.

Abstract: A cradle, having positive buoyancy, and wheels, at the stern, is launched and recovered by a push/pull rod assembly pivotally attached to the forward portion of the cradle platform. Cabling, looping a double pulley forward and a single roller assemble pulley aft, oppositely wound on a reversible drum winch, moves the push/pull rod. A folding stabilizer assembly, doubling as a walk-way between the trailer bed and cradle, is attached at the wing ends of a raised cross tee by pivotally conecting near the tops of two vertical members of the cross tee. Upon the trailer bed, two grooved, parallel rails maintain a close tolerance hold upon a sliding platform assembly. The folding stabilizer is also pivotally attached to this sliding platform.

Abstract: A truck dumping and unloading apparatus which is operated by reverse truck motion and is adapted for mounting on a flatbed truck or a pick-up truck. The apparatus includes a single or double-member, open-top sled having at least a primary compartment adapted for containing trash, garbage or refuse, a sled guide mounted on the back of the truck for receiving a cable, one end of which cable is attached to the sled and a traveling block adapted for traveling on the opposite end of the cable and receiving a pair of tire chains or friction mats for deployment beneath the rear wheels of the truck. Operation of the truck rearwardly and traversal of the tire chains or friction mats by the rear truck tires causes the traveling block to traverse the cable and the sled to slide from the truck bed and dump the trash, garbage, bulk materials or refuse, reponsive to tension applied to the cable by the travelling block.

Abstract: A transport vehicle mounted roll-off hoist having a main frame pivotally mounted on the rearward end of a vehicle such as a semi-trailer or trunk, including a pair of hydraulic lift actuators adapted to move the main frame of the hoist between a horizontal position and a rearwardly inclined position. Hydraulic actuator which means are provided for lifting a container onto the main frame of the hoist or setting off the container from the hoist. An extensible and retractable stop carriage is telescopically connected to the forward end portion of the hoist main frame. Hydraulic acutator and locking means are associated with the stop carriage for placing the container in the optimum position for transport on the vehicle. The hoist is capable of handling containers of both the outside rail and the inside rail type.

Abstract: An extendable boat trailer has a wheeled chassis adapted to be secured to a towing vehicle, and a boat supporting cradle movable rearwardly and forwardly on the chassis. The cradle includes a rear section which is engaged by a low friction conveyor in the form of rollers on the chassis for guiding the rearward and forward movement on the chassis, and a forward section extending upwardly and forwardly relative to the rear section. The forward section includes retaining members thereon that are cooperable with rollers on the chassis for engaging the rollers on the chassis when the cradle has been fully extended. A removable towing hitch is separable from the trailer, and the trailer includes only one winch.

Abstract: A method and apparatus for loading of a piece of equipment on a lorry. The apparatus includes an arm pivotally interconnected with the lorry and a first jack interposed the lorry and the arm. A jib is telescopically interconnected with the arm. A movable platform is interconnected with a hook on the jib. A cable passes over a pulley interconnected with the movable platform and is hooked to the chassis at one of its ends and to the piece of equipment at the other of its ends. The method includes the steps of moving the piece of equipment rearwardly along the movable platform, the movement of the piece of equipment therealong acting through the cable and pulley to displace the movable platform rearwardly relative to the lorry until the movable platform and the piece of equipment are displaced to a position wherein they are unbalanced on the lorry. Gravity is then used to permit the lowering, by a tilting action, of the movable platform.

Abstract: A trailer for transporting, launching and retrieving floating box caissons includes a conventional road chassis, a tip-frame pivoted to the rear end of the road chassis and provided with a system for tipping the tip-frame from a normal horizontal position, and a sub-frame slidably mounted in the tip-frame and provided with a system for causing longitudinal translation of the sub-frame in relation to the tip-frame. A hauling carriage is guided for movement within the sliding sub-frame. A system is provided for moving the hauling carriage in translation within the sliding sub-frame. A lock is mounted on the hauling carriage for rigidly coupling a floating box-caisson to the carriage.
