摘要： According to some embodiments, a winch tightening apparatus comprises a mounting plate; a first moment arm coupled to the mounting plate and configured to provide leverage for rotating the mounting plate; and a pawl comprising a first end and a second end. The first end is pivotally coupled to the mounting plate such that the second end pivots to engage a ratchet gear when the mounting plate is rotated in a first direction and pivots to disengage the ratchet gear when the mounting plate is rotated in a second direction opposite the first direction. Some embodiments include a second moment arm coupled to the mounting plate and configured to provide leverage for rotating the mounting plate. Some embodiments include a counterweight coupled to the mounting plate and positioned to rotate the mounting plate in the second direction

摘要： A winch wherein a rope or cable is self-feeding onto a sheave by a spring that is biased so as to push a rope into contact with a grooved outer surface of the sheave. One end of the spring is pivotally supported on a frame that supports the sheave for rotation about its central axis, while the opposite end of the spring is freely flexible. A supporting block is provided for the free end of the spring to support and minimize or prevent damage to the spring. The block has an angled surface for urging the rope away from the sheave, thus, together with a stripper member, assisting removal of the rope from the sheave at a point at which the rope exits the sheave.

摘要： A manual marine winch includes a housing, a rotating drum in the housing, a drum rotating and holding mechanism, and a winch line having a lead in end formed by a webbing strap. The webbing strap can include an integral safety indicator such as load indicating indicia, operating indicia indicative of operating extremes for the webbing strap, reflective material, or abrasion resistant material. The drum may include a slot receiving the webbing strap. The winch line may include wire rope, chain or rope coupled to the webbing strap. The method of tensioning the winch line includes feeding a lead in end of the winch line through the drum, manually pulling the lead in end through the rotating drum removing slack, and rotating the drum.

摘要： A hand winch that includes a drum for carrying a strand wound thereon and including gear teeth, a drive gear having teeth thereon mounted in a driving relation to the gear teeth of the drum, and a handle assembly mounted on the drive gear for rotating the drive gear as the handle assembly is rotated. An engagement assembly 8 is positioned intermediate the drive gear and the handle assembly for winding the strand onto or off of the drum by the handle assembly when the strand is under tension and disengaging the handle assembly from the drive gear when tension on the strand is released to allow the drum to rotate while the handle assembly is stationary.

摘要： A safety mechanism for preventing a cable drum to rotate with overspeed has parallel ratchet wheels which encircle a brake drum. At a periphery of the ratchet wheels are stopping slots wherein a latching pawl is inserted when an overspeed is detected. The slots of the adjacent ratchet wheels are staggered. Thus the braking effect of each ratchet wheel starts at a different point of time.

摘要： Winch arrangement primarily intended for withdrawal of hung trees or other objects, comprising a holding unit for fixing the winch to a stationary object, and a winch unit connected to a frame. The holding unit includes an elongated fastening means which at one end is secured to the frame, while its intermediate portion is drawn around the stationary object and its other end is connected to the frame via a tightening mechanism. The winch unit comprises a drum rotatably mounted on a shaft in the frame for unwinding and winding a flat band which at its free end has a fastener for connection to the tree, a control mechanism for the operation of the drum, and an engageable and disengageable ratchet mechanism for selectively preventing unwinding of the band.

摘要： A self-locking windlass for preventing unwinding of the windlass under load when the force turning the windlass is released. The windlass comprises an eccentric spindle coupled to a shaft and rotatable therewith. A cable has one end secured to the spindle and its opposite end securable to the load. Upon rotation of the shaft and spindle, the cable is wound on the spindle pulling the load toward the windlass. Due to the eccentric spindle, a self-locking position of the windlass is attained during each revolution of the shaft and spindle. In this locking position, the load is incapable of unwinding the cable when the force rotating the shaft and spindle is released. This locking position is attained when the spindle is substantially between the shaft and load and the load force is directed toward the load along a line that is substantially tangent to the spindle and passes through the shaft.
摘要翻译： 一种自锁式起锚机，用于在释放卷扬机的力时，防止起重机在负载下展开。 卷扬机包括联接到轴并与其一起旋转的偏心轴。 电缆的一端固定在主轴上，其相对端固定在负载上。 当轴和主轴旋转时，电缆缠绕在主轴上，将负载拉向卷扬机。 由于偏心主轴，在轴和主轴的每转期间都能实现起锚机的自锁位置。 在该锁定位置，当释放轴和主轴时，负载不能退绕电缆。 当主轴基本上在轴和负载之间并且负载力沿着基本上与主轴相切并穿过轴的线指向负载时，达到该锁定位置。

摘要： A portable hand-operated ratchet-type winch including a feed pawl and a stop pawl, the feed pawl being selectively set for rotation of the drum in a forward or reverse direction. A cam is provided which assists in engaging the feed pawl to cause it to act as a stop pawl with the ratchet in a reversing direction and then to disengage the stop pawl to permit the reversing movement of the drum under control of the feed pawl. The cam is adjustable to selectively provide for a minimum reversing movement or a maximum reversing movement.
