What it is
A monorail carries a trolley hoist along a single beam – straight, curved or with switches – to move loads along a fixed path: between process stations, into a store or over machines. The beam is hung from the roof steel or from its own frames, which World Steel designs and fabricates with the building.
Duty group
Vietnam: cranes are designed, manufactured and inspected to TCVN 4244:2005 and the lifting-equipment safety regulation QCVN 07:2012/BLĐTBXH, with technical inspection before use.
