A double-girder bridge crane is usually a mechanical, electrical and metal structure, similar to a single-span slab bridge, supported at both ends on two parallel elevated rails. Double-girder bridge crane equipment is an important tool and equipment to realize the mechanization and automation of modern industrial production and lifting and transportation production process. Therefore, double-girder bridge crane equipment is widely used in industrial and mining enterprises, iron and steel chemical industry, railway transportation, port terminals, logistics turnover departments and places.
Our products have passed CE (ECM) and ISO Certifications, and you can also specify a third-party agency for quality testing. Fees of third-party testing are not included in this offer.
