20130213744 | ENERGY MANAGEMENT SYSTEM - 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. | 08-22-2013 |
20100068018 | Barrier system for an aircraft loader - 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. The inverted-U-shaped element is slidable between a raised position providing a passage for loads thereunder when both platforms interface and a lower position wherein the transverse element extends across the passage for providing a guardrail between the platforms when the elevator platform extends below the bridge platform. | 03-18-2010 |
20090285658 | AIRCRAFT LOADER - 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. The retractable handrails have an extended position wherein the handrails are raised above the upper elevation level across the goods path for blocking passage of the goods between the loading level of the aircraft and the loading platform. The retractable handrails also have a retracted position wherein the handrails are moved away from the goods path when both platforms extend at the upper elevation level for allowing passage of the goods between the loading level of the aircraft and the loading platform. Advantageously, the aircraft loader of the present invention allows to reach lower, main and upper decks of an aircraft while being safely operated. | 11-19-2009 |
20090257852 | Articulated Aircraft Loader - 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. The articulated aircraft loader is also provided with straightening means operatively connected to the rear chassis for straightening the rear chassis in longitudinal alignment with the main chassis. The present aircraft loader advantageously allows to reach lower, main and upper decks of an aircraft while being compact and maneuverable thanks to its articulated design. | 10-15-2009 |
