FIELD: transportation. ^ SUBSTANCE: drawworks comprises the following components: drum, drive, drum brake, drum rotation switching brake, control systems of brakes, control panel. Control panel comprises base, stand, plank (9) of control panel and levers (10), (11) of brake control systems. Plank (9) of control panel is arranged with the possibility of horizontal displacement relative to stand (8) and is equipped with guides inclined relative to axis of panel symmetry. Levers (10, 11) of control systems interact with guides (13). In order to provide for possibility of horizontal displacement of control panel plank (9) relative to base (7), groove (14) is arranged in plank (9). Bolt (15) arranged in groove (14) is fixed to stand (8), at that groove (14) walls serve as guides for bolt (15) during horizontal displacement of plank (9). ^ EFFECT: increased reliability of design. ^ 4 dwg |
