In order to prevent the turntable from sliding when driving, a turntable locking device is provided. The rotary mechanism is driven by a quantitative motor. The output gear of the slewing mechanism is engaged with the slewing support gear. Realize the crane turntable to make 360° rotation along the center of rotation. The amplitude of the lifting arm is controlled by a single or double hydraulic cylinder through oil. The lifting mechanism is driven by an oil-controlled variable or quantitative motor through a reducer. Because of the use of hydraulic torque converter, the motion energy of the crane's various institutions is infinitely variable, which can make the load drop by dynamic control under the freting speed. In order to prevent over-winding, a three-lap wire rope protection device and an alarm device are provided. Medium and large tonnage truck crane can be configured according to the market needs of the auxiliary hoisting mechanism, for double hook operation.
