15 tons single girder gantry crane

I need a set of 15 ton single girder gantry cranes with a span of 18 meters, a height of 10 meters, and an overhang of 6 meters each. It is required that the product quality is excellent, the after-sales service can keep up with the demand, the price can be negotiated. You can send design drawing, gantry crane parameter list and quotation to email: aleksanders.vays@bk.ru
