摘要： A performer lift has abase portion (10) and an extension portion (12). The base portion (10) comprises a platform (16) and a lifting mechanism (18). The extension portion (12) is attachable to the base portion (10) to extend the height of the performer lift. The extension portion (12) allows a performer lift to be provided having a desired height. The performer lift can therefore be adapted to be used in different stage sets, by reusing the same base portion (10) and attaching different extension portions (12), having different heights.

摘要： A knockdown, portable lift is relatively compact and lightweight for transport and use where there is no existing means for lifting a load between a lower surface and an upper surface or where the existing means cannot be used. Components of the lift are stored in a base portion of the lift and are assembled on site for forming a lift frame extending between the upper and lower surfaces. A platform and drive assembly are supported on the lift frame and are driven together up and down tracks on each side of the lift frame using a rotary drive, such as a hand crank or electric motor, to power the drive assembly. The drive assembly is operable by a person on or off the platform from either the upper or lower surface or traversing stairs over which the platform is moving. The drive assembly incorporates a unique overspeed braking system and a unique clutch arrangement.

摘要： Apparatus and method for simultaneously lifting and placing weights. The apparatus includes a support with a first arm and a second arm extending from the support. Weight supports are arranged at distal ends of the arms. The arms are movable to position weights supported by the weight supports. The apparatus also includes a lifting apparatus operable to selectively raise and lower the support. An operator can articulate the arms to storage locations of weights. The operator can then operate the lifting apparatus to raise the support and lift the weights. The operator can then articulate the arms to move the lifted weights to weight placement locations. The operator can then operate the lifting apparatus to lower the support and place the weights on the weight placement locations.

摘要： An elevation conveyance system for transporting a payload substantially vertically and transversely to a preselected release location. The system includes a track assembly comprising a substantially vertical track, one or more bin assemblies in which the payload is receivable, and one or more car assemblies configured for movement along the track. The car assembly includes a housing subassembly having a means for engaging the track to permit movement of the car assembly along the track, and a conveyor subassembly for transporting the payload substantially transversely relative to the track. The bin assembly is receivable in the housing subassembly and configured to release the payload onto the conveyor subassembly for substantially transverse transportation of the payload to the preselected release location.

摘要： A portable lift is provided. The portable lift includes a top frame assembly, a carriage frame, a base frame, and a hoist mechanism. The top frame assembly is secures top ends of a pair of stringers together. The base frame assembly secures bottom ends of the pair of stringers together forming the portable lift frame. The carriage frame includes a plurality of wheel assemblies each having a plurality of wheels. The plurality of wheels releasably retain to and slidably engage with a stringer of the pair of stringers. The hoist mechanism includes a motor, a spool rotatable by the motor, a pulley secured to the top frame assembly, and a hoist cable wrapped around the spool and running from the spool through the pulley and secured to the carriage frame.

摘要： Concepts of omnidirectional vehicle transport are described. In one embodiment, an omnidirectional vehicle includes a transportation platform, a drive system, and wheels. At a surface level, the vehicle can maneuver in any direction, including longitudinal and lateral directions. The vehicle can also be positioned to engage the wheels with a track having a rack gear to engage with the wheels. A control system of the vehicle can then drive the wheels in engagement with the track to raise the vehicle to a second level. At the second level, the vehicle can maneuver to transfer items onto the vehicle for transportation of the items back to the surface level. After the items are transferred onto the vehicle, it can be positioned for engagement with the track, and the control system can drive the wheels to lower the vehicle to the surface level and offload the items.
摘要翻译： 描述全方位车辆运输的概念。 在一个实施例中，全方位车辆包括运输平台，驱动系统和车轮。 在表面水平，车辆可以在任何方向上进行操纵，包括纵向和横向。 车辆也可以被定位成将车轮与具有齿条的轨道接合，以与车轮接合。 然后，车辆的控制系统可以驱动车轮与轨道接合，以使车辆升高到第二水平。 在第二级，车辆可以操纵将物品转移到车辆上以将物品运送回到地面水平。 在物品被转移到车辆上之后，它可以被定位成与轨道接合，并且控制系统可以驱动车轮以将车辆降低到表面水平并卸下物品。

摘要： A wheel chair lift device includes a pair of hydraulic cylinders for elevating a lift car above a base resting on the floor. Pivotally-connected floor struts extend between side walls of the lift car to support the lift car floor while allowing the side walls of the lift car to remain vertical to avoid pinching the gates of the lift car.
