摘要：PROBLEM TO BE SOLVED: To achieve settings of a limiter of force in a tower crane, and setting a limiter of torque without requiring a calibrated load for limiting the operation of handling such loads and the time and cost for the settings. SOLUTION: The purpose of the method is to set a limiter of force of the lift equipment having a winch-type lift mechanism 8. The method comprises: mounting a balance 23 between a lift hook 5 and a fixed point 27, making the lift mechanism in the 'setting' mode by adjusting the drive torque, and displaying a requested value related to the limitation of the drive torque, commanding the lift function by a control means for controlling the electric motor 10 in the upward direction, and reading the value of tension force F produced by the balance 23.
