level wind arm for a winch assembly

Номер: US20120175576A1
Автор: Harry Xydias
Принадлежит: Individual

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.

Level winding drum winch

Номер: US20140061558A1
Автор: Michael T. Einhorn
Принадлежит: Individual

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.

Systems and methods for preventing improper lifting of tubular members are described, in which sensing devices are used to detect when a tubular reaches a selected position within a lifting device suitable for engagement, and/or to detect when a lifting operation is initiated that would exceed the capacity of a lifting device. Operators are engaged with the tubular member and provided with a preselected force corresponding to the weight of one or more tubular members, such that when the weight of a lifting operation exceeds the preselected force, an audible device may be actuated responsive to sensor output, to immediately alert individuals, such that the improper lifting operation may be halted. Similarly, an audible device may be actuated responsive to sensor output when a tubular member reaches a selected position within the lifting device, such that additional movement may be ceased.

The present invention provides a cable winch system with a cable guide bar handle and a cable guide clip for evenly distributing cable along a winch spool. 1. A winch system comprising:a cable guide handle constructed and arranged for use with an existing vehicle mounted winch, said existing vehicle mounted winch having cable and a cable winch spool;a base constructed and arranged to secure a cable guide bar pitovably attached to said cable guide bar;a cable guide clip operatively associated with said cable guide handle whereby said cable guide clip threads and directs cable during spooling onto said cable winch spool.2. The system of wherein said cable guide handle is telescopically extendable and retractable.3. The system of wherein said cable guide handle is constructed and arranged to move cable horizontally in relation to said cable winch spool. A winch mounted to the front of the vehicle is a fairly common site. Numerous persons and professions have found a very helpful device in this type of configuration. However, the helpfulness comes with one very significant difficulty. In winding up cable onto a winch it is very important to guide the cable such that the resulting spool on the winch has some level of uniformity. Most often, persons hold the cable and guide it on to the spool with their hand in order to wind the cable uniformly. Very often, persons scratch or cut their hands on the cable during the spooling process. There is a need for a simple device to assist in the spooling while protecting the hands of the user.The present invention addresses this issue.The present invention is a system that will enable a person to safely wind a winch cable without having to hold the cable in their hand.The system guides and steers cable onto winch spool as it is common that winch cables always end up full of jiggers that catch and tear up hands of the user.In one embodiment, the present invention is a winch system comprising:In one embodiment, the cable guide handle ...

DRUM ASSEMBLY AND METHOD OF LAYING A LINE ON A DRUM

Номер: US20150076266A1
Автор: Crawford Alexander Charles, Crawford Andrew, Crawford Patrick John
Принадлежит:

A drum assembly and a method of laying a line (L) onto a drum (D) uses an oscillator device to apply vibrations to the line as it is being wound onto the drum. The oscillator device () sequentially increases and decreases the load on the rope as it is being wound onto the drum, causing differential fluctuations in the tension of the line as the line is diverted away in opposite directions from a straight line path to the drum. The vibrations typically cause a rapidly alternating load on the line, which is additional to any load applied to the line during laying of the line onto the drum. This alternating load typically reduces the available stretch in the line, and therefore assists in compaction of the line on the drum. 1. A drum assembly having a drum arranged to receive a line , wherein the assembly has an oscillator head comprising an oscillator device adapted to generate vibrations , wherein the oscillator head is adapted to engage the line and to apply vibrations generated by the oscillator device to the line as the line is being received onto the drum.2. A drum assembly as claimed in claim 2 , including a tensioning device arranged to apply tension to the line as the vibrations are being applied to the line.3. (canceled)4. A drum assembly as claimed in wherein the oscillator head comprises a guide device that is adapted to divert a path of the line before the line is laid on the drum claim 1 , and wherein the line is at least partially wound around the guide device.5.
