Lifting Capacity 50 Ton Double Dirder Bridge Crane

Lifting Capacity 50 Ton Double Dirder Bridge Crane
Part 1: Description and Application
 
Double Girder Overhead Cranes give a better height of lift in given headroom as the hook travels between the beams. With open winch trolley as its lifting mechanism, they are available in higher capacities than single girder and for heavy duty applications.
Overhead Cranes are available with a huge range of custom options in capacities up to 700t and span up to 60m, helping with all dependable material handling solutions. Our crane provides an excellent overall value.
They are also cab be Custom Designed for severe applications and harsh environments.
