Packaging & Shipping
Packing, Transportation, Storage
The package should be placed on sleeper by normal position and fastened by bolt;
The cabinet should be covered with foam to be protected against dust and vapor during the transportation;
Keep the equipment in its original package when deliver to installation field, so as to prevent it from possible damage during the transportation;
Fix it with fastener to prevent it from resistor looseness during the transportation;
Seal the box with lath;
Indicate delivery place, equipment name, weight etc on the packing box clearly;
All the boxes can be lifted to the common container by forklift;
Unload the goods with forklift or crane after its arrival;
Inspect the goods after unloading to make sure that the goods is in good condition.
