A method for fixing the angular position of a crane boom displaceable during lifting and lowering by means of a winch (3) integrated with a motor (30) driving a drum (31) on which a rope is wound and which is fixed to a pressure plate (40) provided with an arcuate elliptical locking hole (41), the method comprises:-measuring a velocity parameter (PM) representative of the angular velocity of the boom; -controlling the motor to displace the cantilever by limiting the speed parameter to a first maximum value (V1) and limiting the motor torque to a first limit value (C1) until an angular position in which the lock (42) is aligned with the locking hole and then locked into the locking hole is reached; -controlling the motor to displace the boom upon lowering by limiting the speed parameter to a second maximum value (V2) and limiting the motor torque to a second limit value (C2) until the speed parameter remains at zero for a predetermined period of time to stop the motor.

    一种用于固定起重机悬臂的角度位置的方法,该起重机悬臂通过绞盘(3)在提升和下降时可移位,所述绞盘集成有驱动卷筒(31)的马达(30),所述卷筒上卷绕有绳索并固定到设置有弧形椭圆锁定孔(41)的压板(40)上,该方法包括:‑测量代表悬臂的角速度的速度参数(PM);‑通过将速度参数限制到第一最大值(V1)和将马达扭矩限制到第一极限值(C1)来控制马达以移置悬臂,直到达到锁(42)与锁定孔对准并且然后锁定到锁定孔中的角度位置;‑通过将速度参数限制到第二最大值(V2)和将马达扭矩限制到第二极限值(C2)来控制马达以在下降时移置悬臂,直到速度参数在零处保持预定时间段以停止马达。
