Abstract

A gas powered self-contained winch includes a combustion engine, a transmission assembly, a gear assembly and a clutch assembly connect to a spool capable of winding and unwinding a cable wire using forward and reverse drives. A hand controller communicates with the clutch assembly through a cable wire sufficient to control the winding and unwinding of the cable. Securing the winch for operation includes placing its center of gravity below the force line. A field changeable capstan option and remote control handle with throttle, power out lever, and kill switch are built in. A field installable hook float is provided for water rescue operations.

Claims

8. The winch of claim 1, wherein:

the first connecting gear, middle connecting gear and end drive gear are protected through use of a rigid casing.

9. The winch of claim 1, wherein:

the gear assembly includes at least one planetary gear and at least one threaded ring.

10. The winch of claim 9, wherein:

each of said at least one planetary gear has a plurality of planet gears able to fit into a recess within each respective of said at least one threaded ring and receiving an end of the transmission drive.

11. The winch of claim 10, wherein:

the gear assembly also includes a first mounting plate and a second mounting plate to help maintain the planetary gear and threaded ring.

12. A self-contained gas powered winch, comprising:

a combustion engine;

a transmission assembly connected to the combustion engine;

a gear assembly connected to transmission drive;

a clutch assembly connected to the transmission drive though the gear assembly, the clutch assembly having a first connecting gear which fits within a threaded clutch ring which in turn is contacted by a pivoting threaded arm member;

a spool positioned between a first side wall and second side wall that is connected to the clutch assembly, the spool capable of winding and unwinding a cable;

a hand controller connects to the clutch assembly, the hand controller having at least one clutch cable in communication with the pivoting threaded arm member capable of applying pressure to the threaded clutch ring to regulate the rate of release of the cable;

an external casing having a first side wall, a corresponding second side wall, and a top wall, the external casing capable of housing and maintaining the combustion engine, transmission assembly, gear assembly and spool;

the external casing further includes a fairlead which helps support the cable when released and retrieved from the spool; and

a drum having a drum groove located thereon that allows a user to use the winch as a capstan.

13. The winch of claim 12, wherein:

the clutch assembly includes a clutch enclosure capable of protecting components of the clutch assembly.

14. The winch of claim 12, wherein:

the external casing including a stabilizing bar placed between ends of the first side wall and second side wall.

15. The winch of claim 12, further comprising:
