摘要:
Positioning system and method for positioning engine components on an aircraft, the system including a moveable support for the engine component, a laser assembly, and a system controller. First and second lasers of the laser assembly align their respective beams with an engine target position on the aircraft and provide an indication of a first angle of the first laser beam to a reference line, and an indication of a second angle of the second laser beam to the reference line; and the system controller is configured to rotate the moveable support to rotationally position the engine component, determine the vertical distance between the engine component and the target position based at least in part on the first and second angles, and to control a lift mechanism to reduce the vertical distance between the engine component and the engine.
摘要:
Material handling systems for supporting and transferring articles within defined areas from one location to another in which cooperatively spaced support plates (15) are mounted within the defined areas and carriages or shuttles (20) are movably supported by the plates (15) in a manner such that the carriages (20) may be guided along a network of optional routes along open passageways (16) created between the plates (15). The carriages may be mechanized or manually maneuverable and may include load lifting (140) and adjusting (135) components which are selectively operated to raise, support, re-orient and lower the articles so that such articles may be transferred and repositioned as desired.
摘要:
Systems and methods for moving a vehicle component relative to the vehicle, the system including first and second upwardly-extending supports; a lift frame between the first and second supports including a crossbeam, and a pair of cambered truss assemblies secured to the crossbeam and configured to be attached to the vehicle component; movable first and second crossbeam support assemblies on the first and second supports to support the rotation of the crossbeam; a first lift mechanism configured to move the first crossbeam support assembly along the first support in response to a first control signal; a rotational drive mechanism configured to rotate the crossbeam relative to the first and second crossbeam support assemblies in response to a second control signal; and an electronic controller configured to generate the first and second control signals to change the position of the vehicle component relative to the vehicle.
摘要:
Rail-mounted lift systems is disclosed. The lift system includes a rail having at least one conductor positioned on an upper interior surface of the rail. A carriage is slidably disposed in the rail for relative movement to the rail. The carriage generally includes a carriage body, at least one pair of support wheels rotatably coupled to the carriage body and slidably engaged with the rail, and a conductor truck comprising at least one conductive roller rotatably attached to the conductor truck. The conductor truck may be mounted to the carriage body with a biasing member upwardly biasing the conductive roller into rolling engagement with the at least one conductor. A lift unit is coupled to the carriage body and includes a motor paying out and taking up a lifting strap. The lift unit is electrically coupled to the at least one conductive roller.

A rail-mounted lift system includes a rail (102) having at least one conductor (114a,114b) positioned on an upper interior surface (130) of the rail. A carriage (106) may be slidably disposed in the rail for relative movement to the rail. The carriage generally includes a carriage body (140), at least one pair of support wheels (144) rotatably coupled to the carriage body and slidably engaged with the rail, and a conductor truck (146) comprising at least one conductive roller (156) rotatably attached to the conductor truck. The conductor truck may be mounted to the carriage body with a biasing member (168) upwardly biasing the conductive roller into rolling engagement with the at least one conductor. A lift unit (104) may be coupled to the carriage body and includes a motor (133) paying out and taking up a lifting strap (108). The lift unit is electrically coupled to the at least one conductive roller.
摘要:
A mechanism (8) is provided and arranged for temporary stowage of an inactive spreader in the lower side of a crane trolley, by which mechanism the spreader is moved out of the way for crane ropes which operate an active spreader from the same trolley. The mechanism is arranged to be suspended from the trolley and in stowage docking to the stowing spreader, and arranged detachable from the trolley to be supported by the stowing spreader. A method for providing temporary stowage of an inactive spreader in the lower side of a crane trolley is likewise provided, by which method the inactive spreader is moved out of the way for crane ropes which operate an active spreader from the same trolley.
