What kind of machinery is the bridge? Is the bridge crane or bridge crane? What is the difference between the three?
From the beam car handle, through the longitudinal shift, shifting, etc. will step off the beam erection of precast beams to piers. Hope to help you.
And there is walking on the beam, or called the longitudinal displacement. The biggest difference between the bridge erecting machine and the general overhead traveling crane is that it needs to go through the hole itself
Bridge crane is a bridge crane, bridge crane is also a crane, but not a bridge crane, the harsh conditions of its requirements
