The invention provides an external suspension type lifting appliance for a cargo boom of a pinch roll. The external suspension type lifting appliance comprises a lifting beam, a counterweight pulley, a lifted object receiving hole block for locking a lifted heavy object, a sensor, a driving mechanism for driving the counterweight pulley and a control cabinet. The control cabinet is arranged on one side of the lifting beam of a cargo boom body, the counterweight pulley and the driving mechanism for driving the counterweight pulley to move along the lifting beam are arranged in the middle of the lifting beam, a lifted object receiving hole block is arranged on the other side of the lifting beam to lock the lifted heavy object, the sensor is arranged in an inner cavity of the lifted object receiving hole block to transmit weight data of the lifted heavy object to the control cabinet, and the control cabinet controls the driving mechanism and drives the counterweight pulley to move on the lifting beam to obtain torque balanced with the lifted heavy object, so that the lifting beam and the lifted heavy object horizontally run. According to the external suspension type lifting appliance for the cargo boom of the pinch roll, the counterweight pulley is arranged on the lifting beam, the sensor detects the weight of the pinch roll, a gear motor controls a lead screw to drive the counterweight pulley to horizontally move on the lifting beam, and the balance torque with a sling as the center point is obtained. The external suspension type lifting appliance is suitable for being used as a cargo boom external suspension type lifting appliance.

    本发明提出的是一种用于夹送辊的起重臂外悬挂式吊具。包括吊梁、配重滑车、锁紧吊运重物的吊物接孔块、传感器、驱动配重滑车的驱动机构和控制柜;在起重臂主体的吊梁一侧设有控制柜,吊梁的中部设置有配重滑车和驱使配重滑车沿吊梁移动的驱动机构,吊梁的另一侧设置有吊物接孔块锁紧吊运的重物,吊物接孔块内腔设置有传感器将吊运重物的重量数据输送至控制柜,控制柜控制驱动机构并驱动配重滑车在吊梁上移动,获得与吊运重物平衡的力矩,使吊梁与吊运重物水平运行。本发明采用在吊梁上设置配重滑车,传感器检测夹送辊重量,减速电机控制丝杠驱动配重滑车在吊梁上平移,取得以吊索为中心点的平衡力矩。适宜作为起重臂外悬挂式吊具应用。
