Abstract

PURPOSE: To make possible accurate measuring as well as safe working by controlling the measuring of length of suspension cable in the delivery and the winding and stopping thereof through a guide pulley.
CONSTITUTION: When a suspension cable 2 is delivered in a sonar hoisting cable for helicopters designed to suspended a transmitter/receiver 3 for searching objects under the sea with the driving of a drive section 1b of a winch 1 from a winding reel 1c through a guide pulley 1a, the revolutions fo the guide pulley 1a is measured with a detector 16, and the output is memorized with a memory circuit 13 as a value of delivery length though an integrator 14. Then, as the transmitter/receiver 3 approaches the bottom of a helicoptor with the hoisting of the cable 2, a control device 12 sends a speed reducing and a stop signal to the drive section. Here, the set value of the cable length is corrected according to the detection signal of the intended objects 17 with a detector 15.
