1. PACKAGING.

Cast resin dry-type transformers are not sensitive to natural humidity. Local transportation over short distances on covered vehicles, generally don’t require packaging.

When transporting over long distances or overseas, transformers must be wrapped with protective covering. Furthermore, it must be placed in containers or wooden crates.

2. REQUIREMENTS FOR HEAVY GOODS VEHICLES.

The transportation vehicle must be in pristine condition and obey the country’s highway code. Furthermore, it must adhere to all general statutory instructions (necessary permits etc.)

It is important to furnish the loading area of the vehicle with a heavy-duty weatherproof cover. Because transporting cast resin transformers without a cover is not permitted.

The transportation vehicle must have appropriate tie down loops, to which the transformers can be secured.

Road transport is only to take place with a pneumatic (air-filled) suspension vehicle. If there are differing transport modes or conditions, please consult with your transformer manufacturer.

3. LOADING TRANSFORMERS WITH AN INDOOR CRANE.

First, pull the transport vehicle into the loading area where the crane is. Then remove the weatherproof cover for loading. With the indoor crane, start loading the transformers from the back area of the vehicle.

To lift the cast resin transformer, USE ALL 4 LIFTING LOOPS SIMULTANEOUSLY. Lifting directly by the yoke is not allowed. For crates and containers, only use the indicated lifting points when loading.

Place the transformer in a vertical line on the vehicle’s loading bed, chassis on the floor. If possible, load the transformers side-by-side and aligned in the center of the floor (as in the image above).

You may also load the transformers horizontally to the direction of travel. But only if there’s enough room for the secure attachment of the transformers.

4. SECURING THE TRANSFORMERS ON THE TRANSPORT VEHICLE.

Attach each transformer with 4 ratchet straps, to the peaks of the 4 tie down loops on the vehicle. Do this with a tension bracket of approximately 30° downwards to the loops.

5. LOADING A TRANSFORMER WITH PALLET USING A FORKLIFT TRUCK.

If the transformer is bolted to a suitable transport pallet, load the transformer together with the pallet. As described above, continue to attach the transformer and pallet with 4 ratchet straps.

A forklift truck without a pallet is not permitted, as it only leads to the damage of transformers.

6. LOAD-SECURING DEVICES.

During transportation, strains occur on the load:
1. Length-ways: Forces from start and braking actions.
2. Cross-ways: Forces when going around bends.
3. Vertically: Forces when going over bumps.

It’s important to secure the load and safeguard any forces that occur during transport. Load-securing devices must include these forces into the vehicle’s loading bed. Be sure to use approved load-securing devices. Especially in terms of load-securing devices and tie down forces. Also bear in mind the load balancing.

These are basic guidelines, and you should take care to follow your manufacturer’s instructions at all times.
