摘要： An elevator with a brake device may be configured to provide a variable brake force, from a minimum brake force up to a maximum brake force (Vmax). The brake device may include a first energy store that provides the maximum brake force and a second energy store that provides an adjustable counterforce. The adjustable counterforce may be directed in an opposed manner with respect to the maximum brake force provided from the first energy store. Further, the variable brake force may amount to a difference between the maximum brake force and the adjustable counterforce. In some cases, the first energy store may comprise a compression spring for providing the maximum brake force.

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.
摘要翻译： 电缆卷绕鼓设置有具有内齿轮齿和外棘齿的齿圈，并且鼓和齿轮被支撑在壳体中，用于围绕鼓轴线以相反的方向旋转，以实现电缆相对于滚筒的卷绕和展开 。 滚筒通过包括曲柄致动的曲柄和小齿轮组件，棘爪和棘爪致动杆的操作机构在相反方向旋转。 小齿轮由壳体支撑并接合内齿轮齿，并且在曲柄沿卷绕方向旋转期间，小齿轮使滚筒旋转并且棘爪接合棘轮齿以防止滚筒沿展开方向旋转。 在棘爪与棘齿接合期间，当曲柄在展开方向上旋转时，凸轮移动棘爪致动杆以释放棘爪以与棘齿接合，以释放滚筒以在展开方向上旋转。 在曲柄沿鼓卷绕方向的随后旋转之后，凸轮使致动杆移位，以使棘爪与棘轮齿重新接合，从而阻止滚筒在卷绕方向上的旋转期间沿卷绕方向旋转。

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.
