2.2 Storage
The packs must be kept in a covered and protected area in a temperature range 0f -10℃to +40℃. They must not be exposed to direct
sunlight, rain or water.
Stacking the packs
We advise against stacking because the packs are not designed for this type of storage. The narrow base, heavy weight and large size of
the packs make stacking difficult and potentially dangerous.
If stacking is unavoidable, use all appropriate precautions:
-never stack to more than 2 meters in height.
-never make stacks of single packs. Always stack pairs of packs in a cross pattern so that the base is bigger and the resulting stack is more
stable. Once the stack is complete, restrain it using straps, ropes or other suitable methods.
A maximum of two packs can be stacked on lorries, in containers, and in railway wagons, on condition that the packs are strapped
together and restrained to stop them falling.
2.3 Lifting and handling
The packs can be lifted and transported only by using lift trucks. The center of gravity and lashing points are marked on the packaging.
Never attempt to hoist or transport the unit using lifting slings.
Opening the packs
When the lift is delivered make sure that it has not been damaged during transportation and that all the parts specified on the packing
list are present.
Packs must be opened adopting all the precautions required to avoid injury to persons (keep at a safe distance when cutting the straps)
or damage to parts of the machine (be careful that no parts are dropped while you are opening the packing)
Take special care with the hydraulic power unit, the control panel and the platform cylinder.
