Abstract:
A lifting structure (20) for a vehicle, such as a car, comprises a support frame (10) that is adapted to contact a lower portion of the car, lifting means (50) associated with the support frame (10) and adapted to turn between an extended, or high, position (B) and a withdrawn position (A), in order to raise/lower completely the support (10) and the vehicle (100) with respect to the ground. The lifting structure (20) comprises moving wheels (31) mounted releasably to the support frame (10) and that are adapted to move it in a substantially horizontal plane. In particular, the lifting means (50) comprises reversible actuating means (51) for returning the lifting means in the withdrawn position (A) substantially in contact with the support frame (10) in order not to hamper a movement of the structure on the castor wheels (31) and achieving a configuration of minimum encumbrance in height. This way, the support (10) with the lifting means (50), in the withdrawn position (A), can be at first arranged under the vehicle without the wheels (31). Then, when the vehicle is raised to the raised position (B), the wheels (31) can be mounted on the support (10) such that the support (10) with the vehicle can be carried exclusively by the wheels (31) while the lifting means (50) can return to the withdrawn position (A).
Abstract:
A loading device (10) for lifting and loading cargo onto aircraft includes a support frame (12) and at least one lift platform (20) that can be raised and lowered relative to the support frame. A retractable barrier (32) is provided between the lift platform and the support frame to provide a physical and visual cue to impede or discourage persons from intruding into dangerous areas of the loading device during raised operation.
Abstract:
The invention provides an aircraft loader for loading and unloading goods in and out of an aircraft. The aircraft loader is provided with an interface device for interfacing the loading platform with the loading level of the aircraft. The interface device has a bridge platform and retractable handrails mounted along one of the ends of the bridge platform for advantageously providing working area for the operator of the loader and the operators inside the aircraft. This protected area advantageously has a secure configuration which provides a good vision of the loader parts and aircraft bay to the loader operator while providing a safe emergency path always accessible to the operators. Advantageously, the aircraft loader allows to reach lower, main and upper decks of an aircraft while being safely operated.
Abstract:
A lift platform, which comprises a working plane (1), a base (2), and at least one scissor-like articulation mechanism (3) interconnecting the working plane (1) and the base (2). The working plane (1) is fitted displaceable substantially vertically relative the base (2) by means of the scissor-like articulation mechanism (3) and at least one hydraulic lifting cylinder (36) connected to same. The first articulated arms (31) of the crosswise articulated arms in the lowermost scissor-like articulation mechanism (3) are attached to the base (2) by the intermediate of a tilting mechanism (3). The tilting mechanism (4), by means of which the working plane (1) is arranged tiltable in the longitudinal direction by tilting the whole scissor-like articulation mechanism (3). The tilting mechanism (4) comprises at least one tilting arm (41) or equivalent, which is by one of its ends attached to the said first articulated arms (31) by means of an articulated joint (35). The tilting arm (41) is fitted so as to be pivoted around the articulation point (42) between the said tilting arm (41) and the base (2) by means of a tilting cylinder (43) or equivalent.
Abstract:
Aparato de elevación de carga, que comprende un cuerpo principal (2), que comprende al menos un elemento rodante trasero (7), localizado en una zona trasera (8) del aparato accionable por el usuario para maniobrar con el aparato; al menos un elemento rodante delantero (10), localizado en una zona delantera (11) del aparato más próxima al aplicador de fuerza (5) que la zona trasera(8); un elemento rodante giratorio intermedio (12), localizado entre la zona trasera (8) y la zona delantera (11) del aparato y conectado elásticamente al cuerpo principal (2), y estando el centro de gravedad del aparato dispuesto detrás del elemento rodante giratorio intermedio (12) deforma que en situación de carga apoyan en el suelo todos los elementos rodantes (7, 10, 12) mientras que en situación descarga los elementos rodantes delanteros (10) no apoyan, aumentándose la maniobrabilidad del aparato.
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:
A vertical lift mechanism (100, 100a, 100b) including: a lift support assembly (102) comprising an upper frame member (104), a lower frame member (106), the upper frame member is movable between a lowered position and a lifted position. The lift support assembly additionally includes a support mechanism (150) that holds and maintains the alignment between the upper frame member and a lower frame member as well as a powering unit to cause movement of the upper frame.
Abstract:
By a procedure for transportation of car wheels (2) mounted with tires, which are demounted from a car, to another place in a garage for treatment, for example, exchange of tires, the car wheels (2) are arranged in a vertical position side by side on a frame (1), which consists of two - in an initial position - horizontally, or approximately horizontally, mutually parallel bottom rails (3) against which the wheels (2) can rest, and of two side rails (4) arranged over the bottom rails (3), which side rails are arranged approximately level with a central section through the wheels (2), and which are mutually parallel and parallel with the bottom rails (3), and which act as side guides for the wheels (2). The frame (1) is mounted on a vehicle (5), and the side rails (4) can be moved from an initial position, in which they are not gripping the wheels, to a position in which the wheels are squeezed in position between the side rails (4). The wheels are then moved to another place, where the frame (1) is tilted over into a vertical position and the side rails (4) are reverted to an initial position, after which the wheels are removed from the frame (1) for treatment, the frame (1) is brought back to its initial position, and the wheels (2) are after finished treatment again placed in the frame (1), after which the wheels (2) are transported to another place. By this procedure manual transportation of the car wheels from one place to another is avoided.
Abstract:
A lift apparatus generally comprising a base unit, wheels rotatably mounted to the base unit, a handle fastened to the base, a scissor lift mounted to the upwardly facing surface of the base unit, and a horizontally extending platform mounted to the upper ends of the lift. The platform is selectively movable along a vertical axis by actuation of the lift by the user. The platform may include extension platforms hingedly associated therewith in order to increase the effective surface area of the apparatus.
