CABLE ASSEMBLY FOR WORKING MOVEMENTS OF SUCTION DREDGE IN CONSTRUCTION AND CLEANING OF CANAL FROM SEDIMENTS Russian patent published in 2013 - IPC E02B5/02 E02B3/02 E02D17/16 E02F3/88 

FIELD: construction.

SUBSTANCE: cable assembly includes a frame-lifting and swing winches with programmable winding of ropes onto drums rotated with angular speed, which is directly proportional to lengths of wound cables, blocks on the frame-lifting boom of the suction dredge and life ropes with roller carriages arranged on canal shores in parallel to its longitudinal axis. The device is also equipped with a follower cable, branches of which via blocks on the frame of the snapper and the frame-lifting boom of the suction dredge are connected to the frame-lifting winch arranged in the form of two drums arranged on one shaft synchronised with a reversible programmable drive, and are fixed to life cables perpendicularly to the longitudinal axis of the canal with the help of roller carriages. Roller carriages are equipped with fixators, with which roller carriages of swing winches are also equipped.

EFFECT: by control of snapper position in a canal section in connection with suction dredge displacement along the canal axis, the specified curvilinear underwater cross section of the canal is formed, which corresponds to the stable bed of the canal, and production of works is simplified.
