1. Different Production Cost:


Single-beam ( girder ) bridge cranes are short on span and consume less construction material, so its cost is lower. But double-beam ( girder ) cranes have bigger span and consume more, also technical content is higher, so production cost is more higher than single-beam bridge crane.


2. Different Structure:


Generally speaking, single beam ( girder ) bridge crane has relatively simple construction and light own weight. It is also relatively simple in installation, tear and daily maintenance. But for double beam ( girder ) bridge crane, its construction is relatively complicated and own weight is big, also relatively complicated in installation, tear and daily maintenance.
