Difference between single beam bridge crane and Double beam bridge crane

Difference between Single beam bridge crane and Double beam bridge crane, Single beam bridge crane are also called single girder bridge crane, Double beam bridge crane are also called double girder bridge crane. Please check difference in the following:
 1,  Crane working lever difference
 The staff must have certain professional knowledge to repair and install the double girder crane well except for the double girder bridge crane. At the lowest working level of A5, there is A6/A7/A8. The single girder bridge crane has the light weight bearing and the lifting capacity is mostly small tonnage (0.5 ton-20 tons). However, the installation, maintenance and repair of the single girder bridge crane is very simple compared with the double girder crane. When the working level reaches A3, the single beam crane can be repaired and used, but the working level of the European single beam crane is up to A4/A5, but the cost of the European single beam crane is higher.
 2,  Price difference
 The production costs of the two kinds of cranes are completely different. The single beam bridge crane has low cost and low cost. Because it has a lifting beam, less weight lifting, shorter span, less production materials, fewer accessories and so on. Double beam bridge crane has higher price and higher production cost. Because it has two lifting beams, large hoisting capacity, large span, many materials and accessories, high technology content, and tedious production.
 3,  Operation difference
 Another difference is the operation of the two cranes. In the operating mode, the single beam bridge crane is usually operated on the ground, mainly using the wired handle and wireless remote control (only a small number of cabin), and the operation of the double beam bridge crane mainly uses the cab in the air. Occupies more operators (many of them are currently modifying the operation of remote control).
 4,  Performance difference
 The stability of the single girder bridge crane is relatively low, the rated lifting capacity is relatively small, and the working level is relatively low. On the other hand, the double girder bridge crane has relatively high stability, high gravity and high working level. This is the difference in mechanical properties between single beam crane and double beam crane.
 5,  Structuredifference
 Single beam bridge crane (single girder bridge crane) and Double beam bridge crane (double girder bridge  crane), both are bridge cranes.Sometimes they are called "single beam crane" or "double beam crane". the structure (shape) of them is different, In structure, the double girder crane has two bearing bodies. Its tonnage is relatively large, usually between 20 tons and 600 tons.
 So, how to choose a crane is completely unnecessary for customers. It depends mainly on the environment. If it is a small starting weight, the span is short and the use is very small, then a single beam bridge crane is chosen. If the  goods need to be lifted, the span is long, and the use is frequent, the double beam bridge crane must be chosen.

Five Characteristics of Bridge Crane
The series of products manufactured according to international advanced standards is called bridge cranes. The crane has a novel structure, beautiful shape and good technological properties. It has the following advantages: its operation is flexible, stable, safe and reliable.

 Bridge Crane Main Features:
 Box girder bridge, automatic submerged arc welding.
 The new type of conductive steel rail and cable conductance is adopted for tram conduction, which is safe and reliable.
 The lifting mechanism can also set up second sets of safety devices according to the requirements. Improve reliability.
 Standardization, serialization and generalization of crane spare parts
 The control room has a wide range of vision. All the agencies operate indoors and work comfortably and flexibly.
