Abstract: The invention relates to a lifting apparatus of a type which can be used to allow movement of goods to and from and between first and second goods storage areas. The apparatus is located in a space between openings into both of said storage areas and includes a platform which can be raised in the vertical plane so as to allow differences in height between floors of the respective goods storage areas to be taken into account such that for example goods can be moved onto the platform of the lifting apparatus from a first floor height on a first goods storage area to a floor of a second goods storage area at a different height. The lifting apparatus can be used to move goods to and from a floor of a goods storage area which is at the similar height to a support surface on which the other of the goods storage areas is located, with the other of the goods storage areas typically being a vehicle trailer.

Abstract: A portable hoist lifting frame kit has a cross beam 12 that can support an electrically, mechanically, hydraulically or pneumatically operated hoist. The cross beam is secured to or supported by cantilever arms 9 which in turn locate into extension arms 4. The cross beam can move laterally along the length of the cantilever arms. The extension arms locate into protrusion blocks which in turn locate into a wall mounted bracket support system designed to support the load to be raised. The bracket support system is of the mild steel channel type with return lip such as “unistrut”. The portable hoist lifting frame kit can be assembled in various configurations i.e. it can be used with or without the protrusion blocks and extension arms.

Abstract: Systems and methods for lifting a wheelchair in non-residential indoor facilities. Guide rails extend from a wheeled-base and include a bearing and transmission system for raising and lowering a platform on which a wheelchair occupant travels. The bearing system is powered by a hydraulic cylinder with a cable or chain connected to the bearing system. The chain or cable traverses over idler pulleys at various positions about the guide rails and connects to the bearing system at one end and to one of the guide rails at another end. As the hydraulic cylinder is operated, the lifting cable translates the bearing system linearly through the guide rails, which in turn lifts the platform to a desired level. The platform may be adjusted to maintain a generally level orientation even as the guide rails are tilted to accommodate inclinations. Additional outriggers and/or supports may be provided to increase balance and stability of the lift.

Abstract: A system for building shaft casing for dumb-waiters in a building structure with prefabricated assemblies that are readily stackable over each other. One lower, middle and top assemblies constitute the minimum combination typically used in going from one floor to the next. However, the middle and upper assemblies can be repeated depending on the structure where the system is installed. The assemblies include each four elongated corner members with respective ends that receive connecting pin members that permit the structurally stable stacking up of the assemblies. A central and continuous passage is defined. The lower assembly includes two apertures with adjacent compartments within the central passage one to have access to the dumbwaiter and the other one to access the motor and control means. The top assembly has an aperture to provide access to the sprocket mechanism used with the chain that suspends the dumbwaiter within the shaft casing.

Abstract: A processor implemented stabilization system for load handling equipment monitors at least a portion of the equipment weight load at an equipment support member. Reduction below or increase above predetermined values signals an approaching tip over condition and triggers alarm condition responses for stabilization of the equipment. In a counterbalanced lift truck, the equipment weight load on a rear steer wheel is carried by an outer bearing race of a spindle and is transferred from the race to a load cell which is positioned between the race and a shoulder of a mounting tube. The load cell output is received at a processor which monitors the cell to determine if there is an approaching longitudinal tip over condition (toward or away from the load) as well as a lateral tip over condition.

Abstract: A hydraulic platform lift for trucks, having hydraulic and electrical circuitry to provide automated, or automated with manual override, platform levelling capability in the event the truck is tilted. Three embodiments are claimed where levelling may be accomplished in three separate ways; a first embodiment where levelling is accomplished by stopping one side of the platform and allowing the other side to "catch up", a second embodiment where levelling is accomplished by reversing the direction of movement of one side relative to the other to allow rapid levelling, and a third embodiment where the rate of movement of one side is slowed relative to the other, to allow the other side to "catch up" and thereby level the platform.

Abstract: An elevator apparatus for providing an elevated support structure. The apparatus is comprised of a base unit, a plurality of tower sections, and an elevating device. The tower sections may be individually inserted into the base unit where the elevating device operates to raise the base unit whereby an additional tower section may be inserted and connected to the previous tower section. The elevating device is then lowered to the just inserted tower section and repetition of the sequence affects an erection of the tower. Outrigger legs with pads extend from the base unit to provide vertical stability. Guy lines extend from the tower to the ends of the outrigger legs to a winch arrangement within the base unit permitting guy lines to remain taught during the raising or lowering of the tower. Further, ballast containers are provided at the base unit intermediate adjacent outrigger legs for providing additional stability against tip-over.

Abstract: A lift platform has a retention ramp whose forward edge is pivotally connected to a rear edge of the platform by a hinge that permits inversion of the retention ramp to a stowed position overlying the platform. A latch member is mounted on a lateral edge of the retention ramp in operative alignment with a detent block secured to the rear edge of the platform, the detent block having a center on the axis of the hinge. The latch member is pivotally mounted and torsionally biased to press the nose portion into engagement with the periphery of the detent block, the latter having detent notches angularly spaced apart relative to its center for defining intermediate and stowed positions of the retention ramp. During movement of the retention ramp between extended and intermediate positions the nose of the latch engages a convex portion of the detent block periphery of a radius to depress the latch against the biasing force of the torsion spring.
