    摘要： A conveyor belt lifting device for use on a belt-type conveyor comprising a conveyor belt supported by a support structure includes an inflatable bag and is operable between a retracted condition in which the inflatable bag is deflated and an operative condition in which the inflatable bag is inflated and its operably upper surface adopts a shape generally to conform to an underside of the conveyor belt. The invention extends to a method for providing access to components of a belt-type conveyor comprising a conveyor belt supported by a support structure.

    摘要： This invention provides a safety mechanism for a winch assembly when storing a load, such as a tire under a vehicle or a boat on a trailer, in a raised or stored position. The invention finds particular application to a spare tire, but those skilled in the art will appreciate the broader benefits of such a structure when used with a winch assembly for other uses such as a boat winch for a trailer or any analogous use wherein it is desirable to secure a load in the raised or stored position. A unique actuator is described with an improvement of the invention, which includes a control path therewith to control a rod end and thereby actuates in a preferred embodiment a latch by converting rotary motion to linear motion.

    摘要： A simplified wheel-lift mechanism is disclosed. The components of the wheel-lift mechanism are all formed of a plastic material that is corrosion resistant. Further, the wheel-lift mechanism includes a one-piece flexible coupling which reduces the complexity of the system over prior art systems. The one-piece flexible coupling includes a plurality of integrally molded discs connected by a plurality of circumferentially-spaced integrally molded posts. This results in a strong coupling which allows relative angular motion between the ends of the coupling. In a further feature of this invention, a locking key is operable to lock the wheel hub at a particular location. The locking key is selectively released to allow the wheel to be lowered. A unique drive mechanism is also included.

    摘要： A manual hoist with overload preventer wherein rotation in the winding direction under overload is automatically arrested; however, when an overload develops after hoisting or pinching of a load, unwinding is possible. The apparatus includes an operation ring, and a friction ring and a drive ring both being capable of engaging the operation ring. When the driving ring is turned in the winding direction, the operation ring remains engaged with both the friction ring and the drive ring, enabling the relative rotation of the drive ring and the friction ring. When the drive ring is turned in the unwinding direction, the drive ring and the friction ring are rotated as a unit through the operation ring.

    摘要： A ratchet lever hoist (10) which includes an overload clutch (19) enclosed within the hoist handwheel (16). The handwheel is driven through a spline connection with the input drive hub (24) of the hoist, and carries a plurality of first clutch disks 94. Second clutch disks (100) are carried by a load brake drive member (34) and frictionally engage the clutch disks (94) through friction disks (106) bonded to the second clutch disks (100). The clutch is preloaded to a torque capacity corresponding to the rated load of the hoist or a predetermined value over the rated load, such that the clutch will slip, preventing rotation of the load brake drive member when the torque capacity of the clutch is exceeded.
