DH height is determined considering crane space specified the crane rule in JIS
Current design is based on 250 ton crane
If crane capacity is 40 ton, Cavern height will can be reduced. 2 – 3m
Code Number
JIS B 8820:2004
Title
Rated capacity, rated speeds and slewing radius of cranes
Scope of Application
Overhead traveling crane
Bridge crane including unloader
Jib cranes including unloader
