| 254329000 | With means affixing drum to supporting base and allowing relative movement therebetween | 10 |
| 20100237304 | Kinematic Mount - A cable-wound drum style hoist with a rotating shaft supported by bearings that has both: (i) some freedom of motion in (at least) one of the bearings; and (ii) a pillow block in the shaft to impart some freedom of motion (beyond freedom to rotate about the central axis) in the shaft itself. By allowing some freedom of motion both the bearing(s) and the shaft, the hoist can better accommodate for bent shafts and/or slight misalignment of coaxial bearings. Also, a set of preferred connection hardware for mechanically connecting a hoist reducer box to a hoist backbone with preferred degrees of freedom/constraint. | 09-23-2010 |
| 254330000 | Movement engages or disengages drum from drive | 1 |
| 20100258773 | DRUM WINCH - The invention relates to a drum winch ( | 10-14-2010 |
| 254331000 | Movement occurs along line collinear with rotational axis of drum during pulling of cable | 2 |
| 20130240809 | CABLE WINCH DEVICE - The present invention relates to a cable winch device, particularly to a cable winch device for a crane, having at least one cable winch, with at least one cable, wherein the cable is wound and/or can be wound and/or unwound at least partially on the cable winch, and with at least one shifting means by means of which the cable winch can be shifted and/or moved at least partially substantially along the longitudinal axis of the cable winch. The invention further relates to a crane, particularly to a deep sea crane, having at least one cable winch device. | 09-19-2013 |
| 20140061558 | LEVEL WINDING DRUM WINCH - A level winding drum winch has a frame within which a rotatable drum is mounted. The frame is supported upon a pair of tracks upon which the frame may be slid from side to side. A motor connected to the drum rotates the drum for winding or paying out a cable wrapped around the drum. A feed screw attached within the frame is actuated by the motor to slide the frame from side to side as the cable is wound upon the drum. Thus, the cable is continuously directed at a substantially perpendicular angle, without bending or kinking, towards or away from the drum thereby forming a level winding and avoiding damage to the cable. The winch is particularly useful in handling relatively fragile composite cables useful for simultaneously towing and electronically communicating data with the objects towed by a boat. | 03-06-2014 |
| 254332000 | Including pivotal, rotational, or swivel connection between drum and base | 6 |
| 20090127526 | Automatic coiling machine - The automatic coiling machine is a device for automatically coiling an elongated flexible element, such as a fishing line. The automatic coiling machine includes a housing adapted for mounting to a support surface, such as a wall of a boat. The housing includes at least one sidewall. A drive roller is rotatably mounted to the sidewall by a drive shaft. A drive system, such as a motor, is mounted to the sidewall for selectively and controllably driving rotation of the drive shaft and, thus, the drive roller. An idler roller is rotatably mounted to the sidewall adjacent the drive roller and contacting the drive roller so that rotation of the drive roller drives rotation of the idler roller. The sidewall is angled so that an axis of rotation of the drive roller is angled with respect to the axis of rotation of the idler roller. | 05-21-2009 |
| 20090309080 | Turtle Winch for Stage Use - A “turtle” winch that rotates relative to a non-rotatable base. The rotatable part is held in place relative to the fixed base by v shaped grooves held in cam followers. | 12-17-2009 |
| 20100283020 | CORDLESS HOIST - A portable hoist assembly having a housing. The housing has a recoil spring secured thereto wherein the recoil spring is secured to a cable spool such that constant tension is provided on the cable spool. The cable spool contains a cable that is secured thereto and has a hook member secured at a first end. An actuating member having a self contained power source and connected to the cable is thus operable to feed and retract the cable. | 11-11-2010 |
| 20110291061 | High Tonnage Winch Systems and Methods - In one preferred form of the present invention, shown in FIG. | 12-01-2011 |
| 20130248789 | CABLE WINCH DEVICE - The present invention relates to a cable winch device, in particular a cable winch device of a crane with at least one cable winch, with at least one cable, wherein the cable is at least partly wound up on the cable winch and/or can be wound up and/or unwound, and with at least one tilting means by means of which the cable winch can at least partly be tilted and/or pivoted about an axis which is substantially parallel to the longitudinal axis of the cable winch. Furthermore, the present invention relates to a crane. | 09-26-2013 |
| 20160096710 | Hoist Assembly - A hoist assembly includes a mount. A plurality of hooks is coupled to the mount. The plurality of hooks engages a ladder. The mount may be coupled to the ladder. A plate is provided. The plate engages the mount. The plate may be positioned above a roof access hatch. A winch is coupled to the plate. A cable is wrapped around the winch. The winch may extend or retract the cable. A hook is coupled to the cable. The hook engages an object. The assembly may lift the object upwardly through the roof access hatch. | 04-07-2016 |
