Abstract: A hydraulic boom gantry and a method of lifting a load associated therewith. The gantry includes telescoping sections with a hydraulic cylinder mounted therein. A swiveling plate structure allows minor deviation between sets of telescoping sections. A collar structure and a pinning structure lock the telescoping sections together. A cam mechanism prevents accidental section retraction and a powered rigging device traverses a beam connecting the telescoping sections.

Abstract: The present invention is a device for picking out individual rods from an unordered bundle independent of the position of the rods in the bundle and their positions relative to each other. The device makes it possible to handle the rods and the picking out process without displacing the objects along their length. When an object shall be picked out and transferred to the receiving level 15, a lifting device 19 is moved up through the objects which are present in the intermediate storage. At the front end of the lifting device 19 there is a V-shaped recess 20. The object so picked up is lifted over to the receiving level 15 thereby that a conveyor 21 is activated. The conveyor extends along the whole length of the intermediate storage and the receiving level and it carries several supporting wheels 23.

Abstract: A power option is provided for a manually-operated material lift that employs a telescoping mast system which is extended or retracted by a winch. A reversible electric motor is connected to the winch via two-way reduction gearing that remains in the drive train during manual operation and requires no clutches or disconnect means. The power option is initiated by selecting the position of a reversing switch that controls the motor, and closing an on/off switch which energizes the motor for rotation in the selected direction. When the on/off switch is open, the lift may be manually operated in the conventional manner.

The motor secondary fits between the primary winding and the backiron as the moving motor primaries travel across the motor secondary, generating thrust.

Abstract: The present invention is an improved wheeled, light-weight lift which meets standards for airline ground support vertical lift devices, specifically being capable of use on airport tarmacs in winds up to 90 mph. On and off-loading ramps are provided which are rotatable between an upright stored position and a horizontal working position. The ramps comprise a bridge structure supporting a plurality of louvred deck plates. Each louvre is linked to the others so as to remain oriented horizontal regardless of the ramps position for minimizing their aerodynamic profile and overturning moment. Outriggers are extendible from the frame so as to increase its base dimensions and thus the moment needed to overturn the lift. The outriggers retract into the frame to minimize storage. The outriggers are horizontally movable along their longitudinal axis to minimize the deployment space required.

Abstract: A material separator separates non-magnetic particulate material into components having differing electrical conductivities and comprises a support frame, a drum rotatably journaled with respect to the support frame, a magnetic assembly in the drum interior and a drive system. The drum's sidewall is cylindrically shaped and the magnetic assembly incudes longitudinally extending magnetic arrays, each angularly spaced from one another and rotatably journaled on a respective array axis that is radially spaced from the drum axis. The magnetic arrays include opposite magnetic poles located along a rotational surface such that when they rotate, an oscillating magnetic field is induced through the drum's sidewall. The drive system rotates the magnetic arrays and the drum so that particulate material placed on an outer surface of the drum sidewall is subjected to the oscillating magnetic field whereby components having different electrical conductivities are discharged with differing discharge trajectories.

Abstract: A device for isolating stacked flat workpieces includes a driven, web-like supporting framework which rotates in a frame. Rotating rolls are supported at equal intervals on a circle concentric to the turning axis of the framework. Each roll is provided with a row of suction boxes. Driving gears of the rolls are rotated, in a direction opposite to the rotation direction of the supporting framework, by a spider gear fixed to the framework. Intermediate gears, through which the spider gear rotates the driving gears, are supported in the supporting framework. A stacking cartridge is placed at the external cylinder defined by the row of suction boxes in such a way that each row of suction boxes of each roll withdraws an exposed workpiece from the cartridge. A transport device which removes an isolated workpiece and further transports the workpiece is placed at the external cylinder. In order to prevent a stack from being set into vibration by a passing roll, a stacking cartridge completely confines the stack.
