For the following 16T crane requirements set up lifting display, 16T and more than 16T crane set torque limiter, and an alarm device. The lifting arm of the hydraulic truck crane is composed of several sections, which can be designed according to the different requirements of the lifting height. One is sequential expansion, and the other is synchronous expansion. Large tonnage cranes in order to improve the lifting capacity of most of the use of synchronous telescopic. The expansion of each arm segment is controlled by oil pressure, and it can be expanded freely. Crane with auxiliary arm, in the running state, the auxiliary arm is generally arranged in the main arm side or below. The turntable is mainly used to arrange the lower fulcrum and control device of the lifting mechanism, rotary mechanism, lifting arm and variable amplitude oil cylinder. For medium and large tonnage cranes, some are still installed on the turntable engine. The turntable and the bottom frame are connected by slewing bearings which can bear vertical load, horizontal load and overturning moment.
