Abstract: There is provided an energy management system for managing a current flow in a machine having a lift element being vertically movable by a motor assembly. The energy management system includes a power supplying bus for supplying the motor assembly, a battery source, an energy storage device and an associated controller, and a main controller for controlling the energy-storage-device controller and thus the powering of the motor assembly, while factoring a height and a movement of the lift element. The system generally seeks to manage the energy flow between the battery, motors and supercapacitors so as to maintain the battery current as low as possible by controlling the motor's speed, to maintain the battery power demand constant over time, and to store the regenerated energy into supercapacitors in order to avoid recharging the battery during operation, as well as to maintain the supercapacitors energy level as high as possible.

Abstract: This invention concerns an aircraft cargo loader comprising a deck platform; a front and a rear wheel assembly units; and a scissor assembly extending under the platform for supporting it and move it between an open and close position. The scissor comprises a first and a second elongated arm pivotally connected by a swivel joint. Each of the first and second elongated members have an upper end pivotally attached to the deck platform and a lower end pivotally connected to the rear and front wheel assembly unit respectively. One of the first and second elongated members is articulated and comprising an upper segment pivotally connected to a lower segment. The loader comprises a first controllable actuator to move the scissor assembly between the open and close positions and a second controllable actuator to actuate the upper segment relative to the lower segment so as to tilt the deck platform longitudinally.

Abstract: This invention concerns an aircraft cargo loader for lifting cargo and freight onto and off an aircraft or plane by the loader comprises a longitudinal deck platform; a supporting assembly extending under the platform for supporting and moving the deck platform between a raised position and a lowered position; and an adjusting mechanism installed in connection with a front transverse shaft of the supporting assembly for transversally tilting the platform between a first tilt angular position where one of the longitudinal side of the platform is tilted with respect to the other longitudinal side; a neutral angular position; and a second tilt position where the other longitudinal side of the platform is tilted with respect to said one longitudinal side. The loader also comprises an actuator to actuate the rotational movement of the front transverse shaft.

Abstract: An aircraft loader including a bridge platform, an elevator platform and a barrier system is provided. The barrier system has first and second guiding elements respectively attached to the bridge platform on each side thereof, and first and second supporting elements respectively mounted on a corresponding side of the elevator platform. The barrier system is provided with an inverted-U-shaped element having first and second legs and a transverse element extending therebetween, each of the legs being slidably mounted inside a corresponding guiding element and cooperating with a corresponding supporting element adapted for supporting the legs and driving the inverted-U-shaped element with the elevator platform.

Abstract: The invention provides an aircraft loader for loading and unloading goods in and out of an aircraft. The aircraft loader is provided with a main chassis and a loading platform mounted thereon. The aircraft loader is also provided with an interface device mounted on the chassis for interfacing the loading platform with the loading level of the aircraft. The interface device has a bridge platform provided with a transfer portion extending between the ends thereof. The bridge platform extends in adjacent alignment along the unloading end of the loading platform when both platforms extend at the upper level for providing a goods path between the loading platform and the loading level of the aircraft through the transfer portion. The interface device also has retractable handrails mounted along a respective one of the ends of the bridge platform.

Abstract: The invention provides an articulated aircraft loader for loading and unloading goods in and out of an aircraft. The articulated aircraft loader is provided with a main chassis having a main loading platform mounted thereon. The main loading platform is moveable between a lower elevation level and an upper elevation level substantially coplanar with the loading level of the aircraft. The articulated aircraft loader also has a rear chassis connectable to the main chassis and provided with a rear loading platform moveable between a lowermost elevation level and a second elevation level comprised between the lower and upper elevation levels for allowing transfer of goods between the main and rear platforms. The articulated aircraft loader also has articulated connecting means operatively connected to each of the main chassis for articularly connecting the rear chassis to the main chassis.
