Abstract: A cable guide for a winch having a lifting drum over which a cable is wound back and forth between two end flanges. A guide body in the form of a truncated cone is slidably mounted upon a pinion that is located adjacent to one end of the drum, generally perpendicular to the axis of the drum. The guide body contains a groove at its narrow end in which the cable rides as it approaches the end of the drum. The guide smoothly plays the cable onto the drum so that it can reverse its direction without producing multiple wraps at the end of the drum. A spring biases the guide body into a home position to accommodate the cable during the time the first wrap is being wound on the drum. Thereafter, the guide automatically moves back against the spring force to automatically align itself with regard to further wrapped layers.

Abstract: A belt hoist for allowing fixture of a belt to a winding member to be strengthened to improve the reliability, with a simple structure. The winding member around which the belt is wound includes a shaft insertion bore at the center thereof; a belt fixing surface for allowing the belt to be fixed on a winding periphery; and a belt holder fitted on the belt fixing surface to press an end portion of the belt against the belt fixing surface. The belt fixing surface has a width not less than an inner diameter of the shaft insertion bore, and a fixing bore is so bored in the belt fixing surface as to escape from the shaft insertion bore, whereby the end portion of the belt is inserted in and fixed between the belt fixing surface and the belt holder by a fixing member fixed into the fixing bore.

Abstract: A winch drum having a cable wrapped around a cylindrical surface of the drum and clamped to one end plate of the drum is modified by the addition of a member which inhibits reverse winding of the cable onto the drum. The member is attached to the clamped end of the cable and includes a tubular portion which is arcuate so as to follow the curvature of the cylindrical surface of the drum with a part cylindrical plate portion which projects outwardly to one side of the cable so as to lie flat against the cylindrical surface of the drum. When the cable is paid out to the maximum position, the member leaves the drum and impacts the frame of the winch to prevent or inhibit continued rotation of the drum in the payout direction which would otherwise cause winding of the cable in the reverse direction. The device for preventing reverse winding is particularly useful in winches which include a safety brake to restrict and control payout of the cable.

Abstract: A remote controlled winch operable by a hand held remote control. The winch has a single piece drum that is reversibly driven by a drive motor through a planetary gear arrangement for winding cable onto the drum and unwinding cable off the drum. A remote control capable of handling the high amperage draw of the drive motor is provided to control power to and the rotative direction of the drive motor. The remote control has two switch arms that are connected to the motor leads with each of the switch arms normally biased to a ground connection. A manually operated mechanism is provided to selectively and independently switch (move) each of the switch arms from a ground connection to a connection with a power source to supply power to the motor and control the rotative direction of motor.

Abstract: Elevator compensation ropes are attached to the elevator cab frame by means of a wedge block which is mounted on a lower portion of the frame. The wedge block has a plurality of separate wedge-shaped passages thereon through which each of the compensation ropes passes upwardly. The ropes are looped over V-shaped inserts and then passed downwardly through the passages. The inserts are dropped into respective ones of the passages so as to wedge the ropes against the wedge block. The counterweight is connected to the compensation ropes with a plurality of rope deflectors which guide the ropes from a fanned out series of thimble rods to a closely spaced parallel rope array which extends from the counterweight into the hoistway pit.

Abstract: A winch strap anchor for securing the strap of a winch to the winch drum proximate the hub to maintain a low profile and eliminate crank force irregularities. The anchor is secured to the walls of the drum and is configured to lie against the winch hub thereby minimizing the eccentric winding of the strap onto the winch. The anchor includes a longitudinal slot for receiving the strap to secure the strap to the anchor. The anchor with the strap attached can be manually attached to the winch drum securing the strap.

Abstract: A sheave plate and cable assembly for a tire lift/carrier winch comprises a sheave plate having spaced apart side faces defining a plate thickness therebetween and having an outer peripheral edge interconnecting the side faces and including an arcuate cable-wrapping track thereon. The end of a cable extends into the sheave plate between the side faces and is captured therein by the sheave plate which is die cast therearound. A portion of the cable end extends into the sheave plate in arcuate manner about the axis of rotation of the sheave plate and terminates in a flattened head portion. The thickness of the captured cable end is less than the plate thickness whereby the cable end is confined between the side faces of the sheave plate and does not extend beyond the side faces into adjacent side plates of the sheave assembly.

Abstract: In a method and a device for paying out or hauling in a supply line cable of an underwater device from a ship or a suitable platform, the supply line cable is guided from a drum of a winch through a lower guide roller and over the edge of the ship. A pivoting device is rotated from a vertical position into a horizontal position about the axis of the lower guide roller, or about an axis parallel thereto, for lockingly coupling or uncoupling the cable coupling of the supply line cable to a cable coupling of another supply line cable. As a result of the rotation of the pivoting device, it serves as a horizontal working platform for the coupling or uncoupling process. The pivoting device is returned to its vertical position after the coupling or uncoupling has been completed. The pivoting device is dimensioned in such a manner that the cable couplings of the two supply line cables can be aligned with one another at a spatial distance governed by necessary cable connecting lines.

Abstract: The sheave and cable assembly includes a center sheave plate having an arcuate, cable-wrapping track and an exterior shoulder truncating the cable-wrapping track to accommodate a cable end fitting that is supported between adjacent sheave side plates for rotation relative to the sheave. The end fitting includes an outer, arcuate cable-wrapping shoulder which is generally contiguous with the cable-wrapping track on the center sheave plate when the end fitting is in a "cable wrap/unwrap" position in cooperative relation to the sheave center plate. This position of the cable end fitting permits wrapping of the cable on the track by rotation of the sheave in one direction and paying off (unwrapping) of the cable by rotation of the sheave in the opposite direction. When the cable is payed off the track and the sheave is rotated in a "wrong" direction (i.e.

Abstract: An emergency device for the control of the displacement of a conveying carrier for a nuclear fuel assembly, in which the conveying carrier (6) moves under the effect of a push-pull chain (15) actuated by a driving mechanism causing, according to the direction, its winding on itself in spiral so as to pull the carrier, or its unwinding by forming then a carrier rigid pushing element, including a connecting member between the chain and the carrier, formed of two portions (27,38) connected to each other by a pin which can be broken when required in order to disconnect the two portions and to free the carrier from the chain.Breaking of the pin is due to the effect of a traction exerted remotely from the carrier on a control cable (16) such that, after breaking, the cable can apply a traction on the carrier so as to bring it back freely, independently of the chain, to a predetermined position.

Abstract: An end face of the cable drum is provided with a straight groove into which the cable end is clamped either directly by screws or by a screw fastened holding block. The groove merges through curved portions on one or both ends with a cable receiving grooves on the drum's periphery. A two arm cable guide or a cable hold down device is provided.

Abstract: A compact, lightweight, electrically powered hoist with a drum used for hoisting or lowering a payload. A vertically oriented reversible motor is controlled by a control pendant with a momentary switch to drive a helical gear reduction and a worm gear reduction. A worm shaft and a drum shaft wind wire rope on a drum. A one-way clutch and a brake on a driven shaft free-wheel during hoisting operations. A clutch and brake hold the payload in a hoisted position. Lowering of the hoisted payload is accomplished by reversal of the motor, and driving a shaft and clutch against the torque of the engaged brake. A wire rope with a swaged fitting is anchored to the drum by engagement in a keyhole. The hoist may be mounted horizontally, vertically or on a ceiling.
