Bridge overhead bridge type high-altitude crane

The invention relates to the technical field of bridge cranes, and discloses a bridge overhead bridge type high-altitude crane. When the top frame shakes, the top frame pushes the clamping arm to move, so that the clamping arm shrinks into the transfer cylinder to push hydraulic oil in the transfer cylinder, the hydraulic oil in the transfer cylinder is pushed into the straight cylinder, and energy transmitted by the hydraulic oil is guided to the ground through the straight cylinder, so that the shaking force of the top frame is reduced, and the stability of the crane is kept; and the closing arm is driven by the rotation of the adapter cylinder to move downwards to push the friction ring, so that the friction ring is attached to the shaft of the bottom wheel, and the bottom wheel is subjected to friction speed reduction, so that the bottom wheel is prevented from continuously rotating, the crane is prevented from sliding, and the safety of the crane is effectively improved. 本发明涉及桥式起重机技术领域，公开了一种桥梁架空桥式高空起重机。通
