What it is

A semi-gantry combines a gantry leg on one side with an overhead runway on the other – usually the column line of a building. It serves a strip along the wall inside or outside the building without a second runway, a common solution for loading areas and lean-to bays.

Duty group

FEM and ISO duty groups for cranes and hoists
Duty groups – FEM 9.511 and ISO 4301.

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.
