European-spec Double Girder Overhead Crane has advanced technology and is designed in accordance with international standards: DIN (Germany
), FEM (Europe), ISO (International). It has the advantages of strong rigidity, light weight and outstanding structural design, which can effectively save plant space and Investment cost, unique walking structure characteristics, is your best choice.
European-spec Double Girder Overhead Crane is widely used in workshops, warehouses and other material handling occasions in machinery manufacturing, metallurgy, petroleum, petrochemical, ports, railways, civil aviation, electric power, food, paper, building materials, electronics and other industries. It is especially suitable for material handling, precision assembly of large parts and other occasions that require precise positioning, and the working environment temperature is -25-40 ℃.
European-style double-girder bridge cranes are intelligent equipment, and a variety of functional interfaces are reserved to make function expansion easier;
The European-style double-girder bridge crane has more reliable performance and lower failure rate, which can reduce the cost of use and post-maintenance, and the service cycle can be as long as go years, without worries. Single girder cranes usually refer to single girder overhead cranes. The main beam of the single-girder crane bridge is mostly made of I-shaped steel or a combined section of steel and steel plates. Lifting trolleys are often assembled with chain hoists, electric hoists or hoists as lifting mechanism components.
The European-style double-girder overhead crane has advanced control technology and high-quality key components, which can ensure that the overall performance of the crane is more reliable, the crane starts and runs smoothly, without impact, and has a good mute effect, which can reduce the harm of noise.
