| 254339000 | Having plural, distinct drive sources or discrete drive trains | 9 |
| 20100051889 | PERSONAL LIFT DEVICE - A personal lift device is disclosed having a motor having an output shaft. A gearing system is operatively connected to the output shaft for increasing torque. A strap for suspending a weight is wound onto a spool and rotating the spool extends and retracts the strap. A drive connection is made between the gearing system and the spool to permit said motor to drive said spool. A brake is associated with said spool to prevent unwanted extension of said strap from said spool, when a weight is suspended by said strap. In a preferred embodiment a clutch is provided between the brake and the drive train, and the greater the weight supported by the spool the greater the braking force. An emergency lift and lower device is also provided in the event of a failure of the motor. | 03-04-2010 |
| 20120068131 | Portable Hoist - A portable strap hoist comprises a generally rectangular frame. An upper hook is mounted at a top of the frame for mounting the frame to a structure, in use. A drum includes an insulated strap wound about the drum supporting a lower hook for supporting a load, in use. A spline shaft is operatively associated with the drum to rotatably mount the drum to the frame. A driven gear is mounted to the shaft. A portable housing is mounted to the frame and includes a handle and a drive in the portable housing including a drive gear operatively engaging the driven gear. | 03-22-2012 |
| 20150123056 | TACKLE FOR DISPLACING A LOAD - The disclosed tackle for displacing a load includes a hydraulic motor assembly for displacing a tensile member that is connectable to the load and a hydraulic pump assembly to drive the hydraulic motor, which hydraulic pump assembly is manually operable for driving the pump. | 05-07-2015 |
| 254340000 | Including two or more motors | 6 |
| 20090309082 | Fan Cooled Winch - A winch may include a drum, a winch motor adapted to rotatably drive the drum in a first direction and a second direction, a cable adapted to be wound off of and onto the drum, and a fan including an impeller selectively driven by a fan motor. The fan is adapted to cool the winch motor. | 12-17-2009 |
| 20110303886 | DRIVE ASSEMBLY AND APPARATUS FOR HOIST - An assembly is provided that can include a motor; a planetary transmission coupled to the motor; and a spool coupled to the transmission, and the motor is disposed or disposable partially within the spool. | 12-15-2011 |
| 20120273739 | ROTARY DEVICE AND WINCH PROVIDED WITH ROTARY DEVICE - A bracket of a rotation device of the present invention has a guide mechanism that is configured to guide a first motor and a second motor so as to rotate the same about an axis of a cylindrical rotating body relative to each other. A first gear and a second gear can respectively be meshed with rotating body side gears corresponding thereto while the first motor or the second motor is deviated around the axis of the cylindrical rotating body from a normal attachment position with respect to the bracket. Further, the first motor or the second motor can be guided to the normal attachment position by the guide mechanism in the condition. | 11-01-2012 |
| 20150076427 | ASSEMBLY COMPRISING A SECURITY APPARATUS EQUIPPING A LIFTING DEVICE, IN PARTICULAR A WINCH, AND SYSTEM FOR ACTUATING SAID APPARATUS - This assembly includes a security apparatus equipping a lifting device, in particular a winch, and a system for actuating the apparatus The security apparatus includes a toothed wheel, wedged on the shaft of the lifting device, and a worm meshing with the toothed wheel. The assembly also includes: a splined shaft secured to one end of the worm; a pocketed wheel with inner and outer splines, engaged on the splined shaft; an elastic member between the pocketed wheel and a stop piece; a drive wheel with a splined hub, with which the pocketed wheel is capable of engaging rotationally; and a back-up motor, capable of rotating the drive wheel. | 03-19-2015 |
| 20150083985 | Method and System for Operating Winches and Use Thereof - This publication discloses a method and a winch system for powering a winch handling loads at an end of a line associated with a winch drum, the winch being powered by means of one or more electric motors and one or more hydraulic motors via a gear, in that said one or more hydraulic motors are operated when the load in the line exceeds a predetermined load level for taking care of quick hauling in or paying out the line to compensate for vertical motion of the winch, for example vessel due to waves, and the output shaft(s) of said one or more hydraulic motors are connected to the drum shaft through combination of a sun wheel, planet wheels and parallel wheels. Both a system and use of the invention are disclosed. | 03-26-2015 |
| 20160090279 | CABLE WINCH - The invention relates to a cable winch, preferably a sprocket-type large cable winch for deep-sea applications, having a cable drum, the end faces of which are enclosed by end discs, and having at least one drive unit for driving the cable drum. The drive unit comprises a motor and a gear mechanism which on the output side drives an output wheel, said wheel being in engagement with a drive wheel, preferably in the form of a sprocket, provided on one of the end discs. According to the invention, the output wheel of the drive unit is arranged between motor and gear mechanism, and the motor and the gear mechanism extend towards different sides of the end disc. | 03-31-2016 |
