Product Description
Double girder grab bucket gantry crane is usually used in open-air warehouses or along railways. His control method is usually the driver's cab or ground control. It looks in the shape of "A" in appearance, The span of double beam mobile rail grab gantry crane is usually 18-35 meters. Double girder grab bucket gantry cranes are suitable for open-air warehouses and workshops of metallurgical, cement, chemical and other enterprises to carry ore, limestone, ore powder, coke, coal, sand and other bulk particles indoors or in the open air and between fixed spans. Grab buckets are more suitable for bulk materials under natural accumulation. When grabbing underwater materials or special materials, they must be specifically mentioned in the order. When used in the open air, they must be equipped with waterproof equipment.
