Title:
BWS SYSTEM USING WINCH-COMPENSATING TRACTION DEVICE, AND OPERATING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/002661
Kind Code:
A1
Abstract:
In a BWS system (1) of the present invention, a winch-compensating traction device (10-2), provided in a support frame (10) from which a winch wire (21-1) connected to a harness (50) so as to receive a harness-added weight is withdrawn to the outside, performs weight compensation on the harness-added weight by using a weight balance effect of a weight (27) connected to a winch (21) for winding and unwinding the winch wire (21-1), so that manufacturing costs of the BWS system (1) can be less than that of an actuator-compensating traction device and, particularly, user convenience of the BWS system (1) is also provided through minimization of manual operations by using a combination of a weight detection sensor (40-3) and winch upper/lower position sensors (40-1, 40-2).
