Anti-skid self-locking type electric single-beam bridge crane

The invention discloses an anti-skid self-locking type electric single-beam bridge crane which comprises a single steel bridge, a crane body sliding on the single steel bridge and a winch arranged at the bottom of the crane body, and the crane body is provided with a plurality of walking wheels sliding on the single steel bridge. Each walking wheel is provided with a locking device, and the locking devices are used for stopping rotating along with the walking wheels so that the upper portions and the lower portions of the locking devices can abut against the transverse strips and the single steel bridge correspondingly and generate the braking effect. When the walking wheels stop rotating, the single steel bridge and the cross bar can be locked through the friction locking block, two-step operation can be completed only through rotation of the walking wheels, the later maintenance frequency and time are reduced, the equipment cooperation is good, assistance of other equipment is not needed, and the equipment
