This invention relates to a load bearing; Removable devices, namely, to winch winches, and can be used for installation of floating bridges in pontoons for measles,; The aim of the invention is to increase the reliability of operation and simplify I service.

I FIG. 1 shows a manual box I on a winch, a longitudinal section; in fig. 2 shows section A-A in FIG. one; in: FIG. 3 shows a section BB in FIG. 2.; The manual core winch contains a drum 1, an irreversible 2 and a reversible 15 3 drive, a mechanism for switching the drives and a brake. All the mechanisms of the winch-1 ki are mounted on a common frame 4. The non-I reversible drive 2 is filled in the form of a self-contained motor gear reducer. SE I Reversible actuator 3 is a gear reducer. The drive switching mechanism includes a planetary gear and a ratchet. The planetary gear is placed inside the drum 1.25, its carrier 5 is made fully with the low-speed shaft of the gear reducer, and the sun wheel 6 is connected to the low-speed shaft of the worm gear reducer th 7 and with the drum 1 satellite 8. 30 The ratchet wheel has a pawl 9 and a ratchet wheel 10, placed on a gear shaft 11 connected to a gear wheel 12. The brake is made in the form of an impeller 13 mounted on a shaft 14 together jj with gear 5 connected to a gear wheel 12. A cable 16 is wound on a drum 1. The impeller 13 is lowered into bath 17 gear gear.3.

The winch works as follows. Before the cable 16 is slowly selected with considerable effort during removal of the core, the drum 1 is rotated from the worm gear through traction 7, the solar wheel .6 and 45 satellites 8, while the dog 9 rests on ratchet wheel 10 and prevents conduit drove 5.

When the cable 16 is quickly selected with little effort during the lifting of the core, the rotation of the drum I is carried out from the gear reducer by means of the gear shaft 11, the gear wheel 12 through the carrier 5 and the satellites 8 or during lifting of the unloaded ij cable directly from drove

.) through the satellites 8, while the dog 9 slides on the ratchet wheel 10.

When the cable 16 is etched at idle during the fall of the core or the cable is pulled out, the rotating drum 1 through the satellites 8, the carrier 5, the gear wheel 12, the gear 15 and the shaft 14 rotates the impeller 13, which interacts with the gear lubricant and creates a braking torque In this case, the pack 9 is disengaged from the ratchet wheel 10.

When the drum I rotates from the gear reducer or directly from the carrier 5 or when the cable 16 is etched at idle, the sun wheel 6 remains stationary. Thus, due to the planetary gear and the ratchet, the rotation of the drum 1 can be carried out from any gearbox at any time without performing any preliminary manipulations, and thanks to the rim 13, dipped into the gearbox oil bath, the overlap of the cable 16 is prevented due to the drum running out 1 during measles and when the cable 16 is etched at idle, however, the impeller 13 does not prevent the rotation of the drum 1 from the gear reducer and directly from the carrier 5, since the rotation speed of the impeller and 13 and the generated braking torque is negligible. In addition, due to the outflow of the carrier 5, the rotation of the drum 1 can be carried out at a higher speed.
