DESIGN AND DEVELOPMENT OF BRAKE BAND LOAD TEST FACILITY FOR TESTING BRAKE BANDS OF VARIOUS DRAW WORKS MODELS

摘要

The subject matter disclosed herein relates to a brake band test facility structure (200) to test brake band of drawworks. The brake band test facility structure (200) has a base structure (8) which is made of steel and a circular mounting flange (9) is mounted on the base structure to receive a circular brake flange. Further, a hydraulic jack housing structure (15) is mounted on the base structure (8) to house a hydraulic jack (4) and a brake band fixing structure (12) is mounted on the base structure in front of the hydraulic jack housing structure to fix a brake band. The brake band is fixed from one end with the band fixing structure and other end is connected with hydraulic jack via boomerang shaped link. The hydraulic jack applies test load on the one end of the brake band to test the brake band.
