Abstract

A hydraulic system for two cooperating winches, especially two winches for sweeping nets, to automatically exert similar tensile forces on, and consequently an automatic parallel control of, the cables of the two winches, said system comprising for each of said winches a hydraulic circuit that includes a hydraulic pump, a control valve and a hydrostatic rotary motor to drive an associated winch drum, and said system further comprising control means that ensure a force large enough in the two cables to maintain the network stretched sweeper, so that any curvature of the sweeping net results in a difference in traction in said cables, the difference controlling the winch drums, thus automatically rectifying said curvature.
