254335000 | Element repositionable relative to drum | 12 |
20090267038 | HOISTING DEVICE - The invention relates to a hoisting device for use at a wind turbine, in particular for use in a wind turbine nacelle, which hoisting device includes a reel, a drive motor, control mean and a hoisting line. The hoisting line is a rope, which is composed of synthetic fibre material, e.g. a high-tech rope. Hereby it is achieved that the hoisting device can be provided in a compact form, compared with traditionally used hoisting means, since the synthetic rope used as a hoisting line is characterized in having a high tensile strength and a low weight, whereby a rope having a comparable low weight can be used for lifting the same load, for which traditionally a steel wire having a relatively large weight has been used. Further, since the weight of the rope itself is relatively small, a drive motor, gear etc. having reduced capacity, power etc., can be used as compared to a traditional hoist, thereby also aiding in reducing the size, weight, complexity, cost etc. of the hoisting device. | 10-29-2009 |
20100072443 | Mid-span winch with a reel-enclosing support frame - The mid-span winch has a support frame, a reel mounted in this support frame and a handle affixed to the support frame. The mid-span winch has a longitudinal axis extending horizontally from the reel and a vertical axis intersecting the longitudinal axis at a point on the reel. The handle is mounted to the support frame at a location on the support frame which is coincidental with the vertical axis. Wobbling and twisting motions in the winch body are thereby readily perceived with a true amplitude. A corrective action can then be applied to the winch body without using an excessive or a shy force. In another aspect of the present invention, the handle has a hand grip which extends obliquely from the longitudinal axis, whereby both a wobbling motion and a twisting motion on the winch body can be stabilized at once in a same grasp. | 03-25-2010 |

20110193037 | Windlass System and Method - A compact windlass and a method of operating the windlass are disclosed for exerting a force upon a load along a selected direction of force. A drum is extended along a longitudinal axis of rotation and a line is engaged with a surface on the drum. The line is aligned with a line spooling direction transverse to the longitudinal axis of rotation for being spooled onto the drum by a line spooling mechanism located in close proximity with the surface of the drum and engaging the line at a line engagement location juxtaposed with the drum, in response to rotation of the drum in a spooling direction of rotation, and off of the drum in response to rotation of the drum in an unspooling direction of rotation. A load is coupled with the line, and the line is directed between the line spooling direction and a selected direction of force aligned along a load path extending essentially parallel with the longitudinal axis of rotation and placed closely adjacent the drum, as the line is spooled onto and off of the drum, so as to exert a force upon the load along the selected direction of force. The windlass can be oriented in substantially any selected direction so as to orient the direction of force in a corresponding direction, for exerting a force along the corresponding direction, such as a lifting force or a pulling force, upon the load. | 08-11-2011 |
20120175576 | LEVEL WIND ARM FOR A WINCH ASSEMBLY - The present invention relates to an improved level wind arm for a winch drum assembly, and a winch drum assembly incorporating such a level wind arm. The level wind arm includes a cross member adapted to bias against an outwardly extending portion of rope, the cross member being concave so that more force is required for the rope spindle associated with the cross member to “climb” the slope of the cross member, causing a momentary pause in motion of the spindle after it reaches the end of wind stroke. This momentary pause allows for rope being wound onto the drum to rise up the end wall of the drum to create a new layer which is aligned and consistent with the layer below, without causing gaps in the rope or other circumstances which could lead to the rope accumulating at any one point, or becoming tangled. The present invention also includes means of ensuring that tension is maintained in the rope, and that the rope does not jump off the reel and, for example, into the clutch mechanism. | 07-12-2012 |
