Product Description

Double Girder Gantry Crane for Shipyard

Brief introduction of double girder gantry crane

The double main girder gantry crane has strong bearing capacity, large span, good overall stability and many varieties, but its own quality is larger than that of the single main girder with the same lifting weight, and the cost is also higher.According to the main beam structure, it can be divided into two types:Box beam and truss.Generally, a box-shaped structure is used.


Features and Advantages:
1) Reasonable structure
2) Favorable performance
3) Smooth starting and stopping
4) Safe and reliable traveling
5) Low noise, commodious cabin and good view
6) Convenient maintenance, excellent exchangeability for parts and components
7) Energy saving,reduce energy consumption
8) Using transducer for travelling or traversing crane to realize step speed or stepless speed change
9)Primer and finishing paint
10)Crane structure:Steel box type
