High transmission Efficiency Single Girder overhead Crane 15 ton span 1-15m high safety and saving space
Introduction:
European single-girder cranes features: light weight, compact structure and low energy consumption. With unique design concept, it has the characteristics of small size, light weight and small wheel pressure.
Compared with traditional cranes, the limit distance from the hook to the wall is the smallest, and the clearance height is the lowest. The European crane can work closer to the front and has a higher lifting height, which actually increases the effective working space of the existing workshop. Due to the characteristics of light weight and small wheel pressure of European cranes, the new workshop can be designed with smaller space and more complete functions. Smaller plants mean considerable savings in initial construction investment, as well as long-term heating, air conditioning and other maintenance costs.

Components:
The main girder
The main girder is a welded box structure, and the lower flange plate is the hoist running track. The main beam is manufactured in strict accordance with the process flow. The welding adopts a fully automatic CO2 shielded welding production line, which has small welding deformation, high welding seam strength and low residual stress. The welds are inspected according to the national standard GB3323. It has better strength, stiffness and stability.
End carriages
The crane end carriages adopts a rectangular tube integral end beam structure to avoid deformation caused by welding. The large-scale floor boring machine is used for processing and shaping at one time to ensure that the two deflection values of the wheel are within the tolerance range. The improved design of the crane end beam reduces the vertical rigidity and increases the horizontal rigidity, which can overcome the phenomenon that the three wheels of the crane wheel touch the ground and greatly increase the life of the wheel. The end beam structure for installing the wheels incorporates international advanced technology, and adopts an integral boring structure, which has higher installation accuracy.
Lifting Mechanism
The lifting mechanism adopts European type hoist or European type trolley.The hoist lifting mechanism adopts planetary gear, which is compact and light, and is installed in the reel, effectively reducing the size of the electric hoist. Its design adopts modular design to the greatest extent, and its parts are highly versatile. The design standard adopts the European FEM standard, and the selection of parameters such as lifting speed and running speed is more humane. The design has a slow speed and accurate positioning, suitable for installation and maintenance; the design has a fast speed, which makes the lifting mechanism more efficient and more convenient.

Application:
Single-girder bridge cranes have many uses and are widely used in real life. In many factories, many product manufacturers choose cranes for easy handling, and single-girder overhead cranes are more prominent in terms of assisting and transportation.
In addition to general machinery workshops, single-girder overhead cranes are widely used in petroleum and petrochemical, railway construction, civil aviation airports, hydropower plants, ports, papermaking, building materials, metallurgy and other workshops, warehouses, and material yards.
At Bestaro Cranes, we design and make the cranes strictly according to China or international Safety Standard, all our products comply with CE ISO9001:2015 certificates, guaranteed for 12 months, no matter you're at home or aboard,our professional engineers and technical team will offer you their best technology and wisdom.
