20110031204OPERATOR'S CABIN FOR A STRADDLE CARRIER - An operator's cabin for a straddle carrier. The straddle carrier includes a portal frame, to which belong essentially vertical supporting pillars, and a top frame connecting them at the top. On each side of the straddle carrier at the bottom end of the supporting pillars there are wheels carrying the portal frame. The straddle carrier's operator's cabin is mounted in the front part of the straddle carrier resting on the top frame on one side of the straddle carrier's center line in the driving direction. The operator's cabin is mounted to rest on the straddle carrier's top frame with the aid of a separate intermediate frame, which in a situation where the straddle carrier is falling over and the portal frame is crashing to the ground is allowed to move in the straddle carrier's transverse direction. The intermediate frame is equipped with a brake device or with corresponding brake devices to receive and absorb the kinetic energy of the operator's cabin and to bring about a controlled movement and a decelerating force for the operator's cabin before the movement stops in a situation where the straddle carrier is falling over. To the straddle carrier's top frame is mounted and attached at least one slide guide bar extending in the horizontal direction and in the straddle carrier's transverse direction, and the intermediate frame is equipped with at least one sliding wagon, which is mounted to move along the slide guide bar.02-10-2011
20100276386Truck mounted telescopic boom structure including a stowable jib boom with a stowable personnel basket - A truck mounted telescopic boom structure including a stowable jib boom having a stowable personnel basket mounted thereon is described. A mounting structure is provided at the outer end of the innermost boom section of the boom structure and includes means for pivotally moving a work platform or basket between operative and stowed positions. When the boom structure and the jib boom are in their stowed positions, the personnel basket is positioned closely adjacent the jib boom at one side thereof so as to be within the highway width restrictions. The instant invention enables the personnel basket to be connected to the outer end of the jib boom at all times without the necessity of removing the personnel basket from the jib boom when the jib boom and the boom structure are in their stowed positions.11-04-2010
20120152879Screw-Driven Vertically-Elevating Cab - A lifting system for a vertically-elevating cab, the lifting system includes a frame assembly having a first and a second support column, first and a second lift screws which are attached to the, respective, first and second support columns, a cab-lifting beam that has a first and a second end attached to the, respective, first and second lift screws. A vertically-elevating cab is mounted on the cab-lifting beam in such a manner that a center of gravity of the cab is not aligned with a center of the cab-lifting beam. A plurality of rollers are located on each end of the lifting beam. Each one of the plurality of rollers is in contact with a guide bar on each of the respective first and second support columns, and a first and a second power system is connected to the, respective, first and second lift screw.06-21-2012

20080277364Multi-reeve handling and hoisting system - An integrated hoisting system includes a base structural component (BSC) assembled on a structural aperture and containing an opening compatible with a structural aperture. The integrated hoisting system further includes a plurality of primary hoisting components affixed to the BSC, wherein each primary hoisting component is disposed in an opposite diagonal corner on said BSC, and further includes a winch drum and at least one lead sheave and a plurality of load path assemblies, each containing a plurality of sheaves. The system further includes a plurality of hoisting lines, a plurality of termination components affixed to said BSC, each termination component including a monitoring unit and a load cell assembly for terminating the hoisting line, and a device configured to control the operation of the integrated hoisting system.11-13-2008
20110049076Method and Apparatus for Vertically Orienting Precast Concrete Wall Panels - An apparatus orients to a vertical position a precast wall panel formed in a horizontal position. The panel has holes formed in opposite sides thereof. The apparatus includes an overhead crane having a pair of suspended hooks and a lifting beam assembly suspended from the crane hooks. The lifting beam assembly includes a pair of oppositely facing pin carriages each having a pin adapted to be received in one of the panel holes. The lifting beam assembly further includes a motorized drive mechanism for displacing the pin carriages toward and away from each other along the length of the lifting beam. Displacing the pin carriages toward each other along the length of the lifting beam allows the pins to align with and engage the panel holes. Raising the crane hooks orients the wall panel in a vertical position.03-03-2011
