The invention relates to the technical field of cranes, and discloses a double-beam cantilever crane which comprises a bottom plate, a control plate is fixedly connected to the surface of the bottom plate, a balance block is fixedly connected to the surface of the side, close to the control plate, of the bottom plate, a motor is fixedly connected to the top of the balance block, and a lifting rod is fixedly connected to the inner wall of the bottom plate; a hook is arranged on the side, away from the balance block, of the bottom plate, the four lifting rods are divided into two sets, the number of the lifting rods in each set is two, and the two sets of lifting rods are symmetrically distributed relative to the surface of the bottom plate. When the device is used, after the control panel controls the lifting rod to ascend and descend to the needed position, if the height is still not enough at the moment, the motor is started in the moving part at the moment, the transmission rod can be driven to rotate, the transmission rod can drive the threaded rotating rod to operate, and the threaded rotating rod drives the internal threaded sliding block to operate along the threaded rotating rod through threaded connection of the inner wall.
本发明涉及起重机技术领域,且公开了一种双梁悬臂起重机,包括底板,所述底板的表面固定连接有控制板,所述底板靠近控制板一侧的表面固定连接有平衡块,所述平衡块的顶部固定连接有马达,所述底板的内壁固定连接有升降杆,所述底板远离平衡块一侧设置有挂钩,所述升降杆的数量设置有四个,四个所述升降杆分为两组,且每组的数量设置有两个,两组所述升降杆以底板的表面对称分布。本发明当使用时,控制板控制升降杆升降运行到所需位置后,若此时的高度仍不够,此时运动部件内,启动马达,会带动传动杆进行旋转运行,传动杆便会带动螺纹转杆运行,螺纹转杆通过内壁的螺纹连接,带动内螺纹滑块沿着螺纹转杆运行。
