The invention relates to the technical field of cranes, and particularly discloses a crane boom which comprises a bottom plate, a base is fixedly mounted on the upper surface of the bottom plate, a supporting rod is fixedly connected to the upper surface of the base, a connecting block is fixedly connected to the upper surface of the supporting rod, a driving assembly is arranged on one side of the connecting block, and the driving assembly is arranged on the other side of the connecting block. A first groove is formed in the upper surface of the connecting block, a large lifting arm is arranged in the first groove and comprises a left large arm body and a right large arm body, and the left large arm body is arranged on one side of the right large arm body. According to the lifting device, the torque of an object can be reduced when the object is lifted, meanwhile, the influence of wind power and gravity on the lifting device is reduced, so that the lifting device is smaller and more convenient to use, the rotating joint of the large lifting arm and the small lifting arm is smoother in the rotating process, and the loss of energy and substances in the rotating process is reduced.
本发明涉及起重机技术领域,具体公开了一种起重机臂架,包括:底板,所述底板的上表面固定安装有底座,所述底座的上表面固定连接有支撑杆,所述支撑杆的上表面固定连接有连接块,所述连接块的一侧设置有驱动组件,所述连接块的上表面开设有第一凹槽,所述第一凹槽的内设置有起重大臂,所述起重大臂分为左侧大臂和右侧大臂,所述左侧大臂设置在右侧大臂的一侧,有益效果:有效的使得当需要吊运近处物品时不需要将起重小臂完全展开,可以减小起吊物体时物体的力矩,同时减小了受到的风力和重力的影响,使得此装置使用起来更加小巧方便,使起重大臂和起重小臂转动连接处转动过程更加丝滑,减小了转动过程中能量和物质的损耗。
