    摘要: A lever hoist includes a housing in which a load chain wheel and a driveshaft driving the load chain wheel are mounted, as well as a safety brake. A load chain is movable via the load chain wheel. The safety brake brings about an emergency braking in the event of excessive rotational speed of the driveshaft. The safety brake has a locking disc with teeth and a control disc with control cams. The locking disc and the control disc are rotatable in relation to one another in a limited manner. A catch hook is movable in a swiveling manner and has a latch contour and a sensing contour. The sensing contour rests on the control. In response to exceeding a defined rotational speed, the sensing contour lifts off the control disc. The latch contour rotates towards the locking disc and engages with a locking tooth of the locking disc.

    摘要: A load sensing safety device comprises a pulley shaft carrying a pulley. The pulley, in turn, carries a belt that effectuates movement of the patient lift boom. A biasing element applies a spring force against the pulley shaft to move the pulley shaft in a first direction. A switch that opens and closes responsive to movement of the pulley shaft, whereby the switch opens where the pulley shaft is moved to a first position by movement of the spring in the first direction.

    摘要: An apparatus for lifting and transporting toilets with a wheeled C-shape assembly that has a hoist assembly mounted thereon. The hoist assembly includes a ratcheted spool assembly with an off-centered axle and a central axle that, when they rotate, take in a strap simultaneously from both ends. The strap ends are releasably attached to two separate attachment points in a toilet. One of the attachment points utilizes the openings typically found in the rear portion of a toilet where the toilet seat assembly is typically fastened. The other point uses the inwardly recessed rim found in conventional toilets.

    摘要: A cable winding drum is provided with a ring gear having internal gear teeth and external ratchet teeth, and the drum and gear are supported in a housing for rotation in opposite directions about a drum axis to achieve winding and unwinding of a cable relative to the drum. The drum is rotated in opposite directions by an operating mechanism including a crank actuated crank and pinion assembly, a pawl and a pawl actuating lever. The pinion is supported by the housing and engages the internal gear teeth and, during rotation of the crank in the winding direction, the pinion rotates the drum and the pawl engages the ratchet teeth to preclude rotation of the drum in the unwinding direction. Upon rotation of the crank in the unwinding direction during engagement of the pawl with the ratchet teeth, the cam displaces the pawl actuating lever to release the pawl from engagement with the ratchet teeth to release the drum for rotation in the unwinding direction. Upon subsequent rotation of the crank in the drum winding direction the cam displaces the actuating lever to re-engage the pawl with the ratchet teeth and thus preclude rotation of the drum in the unwinding direction during rotation thereof by the crank in the winding direction.

    摘要: This invention is for a winch having a drum for receiving a line. There are two species of the winch. In the first specie, the winch comprises a drum gear and a drum ratchet. There is a driving means for driving the drum gear and the drum. Also, there is a locking means cooperating with the drum ratchet for preventing the rotation of the drum and the unwinding of the line from the drum. In the second specie, the winch comprises a drum gear and means for driving the drum gear and the drum. Also, there are means for preventing rotation of the drum and the unwinding of the line off of the drum.

    摘要: A portable winch-hoist comprises a main supporting frame, with an anchor hook, and carrying a ratchet-driven cable drum and an actuating frame, or lever, which may in practice be generally U-shaped and may span the main frame and which is pivoted for swinging movements about the axis of the cable drum. Pawls carried by the main frame and by the lever are selectively cooperable with the drum ratchet to rotate, to hold, and to release, the drum, so as to reel, and to control the unreeling of, cable carried by the drum, in response to pivotal swinging of the lever.The cable is releasably retained on the drum, being wrapped thereon and passing through portions of the drum at two axially-spaced points, whereby sufficient turns of cable are retained on the drum to assure a capstan or snubbing effect, under all normal operating conditions, with an end portion of the cable arranged for set-screw securement to the drum, whereby cable replacement is simplified. The lever includes provision for attachment thereto of an operating handle, in any one of several positions, for facility and ease of operation, and to assure ample leverage under all conditions; and the handle has a safety link, bendable when the force applied to the handle exceeds a predetermined amount, and the handle also has within it a space adapted to house spare links. When the hoist is used with the cable looped or passing around a pulley of a pulley-block to form two lines, the cable end remote from the drum is releasably secured, by the cable-end-hook, to the main frame in a position which makes it possible to use a lighter construction for the main frame, for a given load capacity, and substantially reduces the minimum distance achievable between the anchor hook and the pulley-block-hook.

    摘要: A windlass drum drive uses a drum axially and rotatably movable on an axially movable shaft with two-part, rotationally oriented fiber units arranged on each end of a drum. A fiber drive unit engages between the shaft and the drum for winding in the windlass, and a fiber brake unit engages between the drum and a fixed surface for braking the drum in any stopped position. Axial movement of the shaft releases both fiber units to let the windlass pay out, and a spring biases the shaft toward engaging both fiber units for winding in and braking.
