In the whole hoisting process, observe following rules:
•
Hoist the MV Station in a vertical manner. Do not drag or drop the MV Station on any
surface.
•
When the MV Station has been hoisted for about 300mm from the ground, stop to
check if all the connections are still firm. After confirmation, continue hoisting the MV
Station.
•
When transported to the final location, the MV Station should be put down slowly and
steadily.
•
The final location should be firm, level, and well-drained. The MV Station is supported
by four bottom fittings on the ground.
5.2.3 Fastening of Connectors
Use slings with hooks or U-hooks to hoist the MV Station.
The lifting devices should be connected correctly to the MV Station.
