Mine shaft sinking winch Safety: head of fixed rope on the production of dual-speed winch drum, due to special design capacity of two-speed winch rope or Kasheng device, not tied to the spool shaft; rope hole can not have sharp edge dual-speed winch manufacturer, rope bent not form an acute angle. Winch total stop switch should be set to prevent the risk of emergencies caused. Mine shaft sinking winch brake performance: winch (except JZA) should have a separate working brake and safety brake. Safety brake force should be used to hammer or spring brake force, JZA type winch brake in case of power outages should be able to manually lift the brake. Working winch brake and safety brake braking torque should not be less than twice the maximum static torque.
