The invention discloses an extended suspension arm for a hoisting transformer of a crane. The extended suspension arm comprises a pedestal, an extended arm, a hook and an induction system, the extension arm is tripod-shaped, and one end of the extension arm is mounted on the pedestal; the hook is fixedly mounted at the other end of the extension arm; the pedestal is used for being connected with a crane suspension arm. The sensing system comprises a controller, a distance sensor and a vibration sensor; the distance sensor and the vibration sensor are both arranged on the hook and electrically connected with the controller. By arranging the extension arm and the hook, direct contact between a crane suspension arm and a transformer can be avoided, enough safety distance between a crane and an electrified body is ensured, meanwhile, the hook is fixed to the extension arm, shaking of the hook can be reduced, and the problems that an existing crane hook is large in control difficulty, poor in precision and large in load swing are solved. And the control precision of the crane jib on the transformer is improved.

    本申请公开了一种吊车起吊变压器延长吊臂,括:台座、延长臂、挂钩与感应系统;所述延长臂为三脚架状,且一端安装于所述台座上;所述挂钩固定安装于所述延长臂的另一端;所述台座用于连接吊车吊臂;所述感应系统包括:控制器、距离感应器与振动感应器;所述距离感应器与振动感应器均设置于所述挂钩上,且与所述控制器均电连接。通过设置延长臂与挂钩,可以避免吊车吊臂与变压器直接接触,确保吊车对带电体有足够的安全距离,同时,挂钩固定于延长臂上,可以减少挂钩晃动,解决目前吊车吊钩控制难度大,精度差与负载摆动大的问题,提高吊车吊臂对变压器的控制精度。
