The invention relates to a C-shaped lifting appliance, in particular to the C-shaped lifting appliance with rapid positioning. The C-shaped lifting appliance comprises a C-shaped lifting appliance body and a positioning device. The side face of a vertical beam of the C-shaped lifting appliance body is provided with a sliding track. The positioning device is provided with a sliding block matched with the sliding track. The positioning device is provided with two electromotors. Output shafts of the two electromotors are each provided with a gear. One of the gears is engaged with a vertical rack on the side face of the C-shaped lifting appliance body. The second gear of the positioning device is engaged with a horizontal rack so that frontward and backward telescopic motions of an electromagnet arranged at the front end of the horizontal rack can be achieved. The upper face, the front face and the lower face of the electromagnet are each provided with a touch-control switch. The upper position, the middle position and the lower position of the side face of the sliding track of the vertical beam of the C-shaped lifting appliance body are each provided with a travel switch used for detecting the position of the positioning device. According to the C-shaped lifting appliance with rapid positioning, based on the difference in the positions of coil steel relative to the C-shaped lifting appliance, by adopting different motion modes, the automatic adjustment is carried out on the position of the coil steel relative to the C-shaped lifting appliance, and clamping and lifting are completed. The working efficiency is improved, the manual auxiliary bundling operation is canceled, the potential risks of the manual operation are avoided, and the labor cost and the time cost are lowered.
