Lifting transformers by crane or hoist
Lifting lugs, welded to all transformer tanks, are designed and provided for lifting the complete unit as
shipped.Daelim recommends lifting by these lugs as the primary means of movement. Care should be taken
toensurestraps,chains,andcablesusedtolifttheunitsareinspectedpriortouse. Allstraps,chains,cables,
and lifting devices should be in good working order with sufficient capacity to perform the job intended.
Straps, chains, and cables should NEVER be looped from one lug to another to form a continuous loop around
the unit or even on one side of the unit. Each chain, strap, or cable should be run only to one lifting lug at a
time to prevent loss of control of the unit in the event of a failure with one of the lifting devices.
Cable pull angles should NEVER exceed 30° from vertical or damage to the lifting lugs may occur. Spreader
beams/bars should be used to hold the cables apart and as close to vertical as possible to minimize the forces
on the lifting lugs and lifting devices.
Skidding/Rolling Transformers

overhead lifting device is limited or not available. If the unit must be rolled, insure that the area is level, free
from obstructions and debris, and is of sufficient strength and thickness to support the load. When rollers are
used, use as many as necessary to distribute the weight uniformly.
Using Jacks to move transformers

radiators, valves, cabinets or sheet metal components. ALWAYS use at least two jacks per side and raise
evenly to prevent warping of the base.
3. Storage
3.1 Storage for 90 days or less
AllDael i munits have been thoroughly dried at the factory and shipped with oil at the correct level. Transformers
should always be stored with oil in place to prevent possible contamination and absorption of moisture.
Transformers should be stored in a dry location with no rapid or radical temperature changes. If possible, the
transformer should be stored in its permanent location on the foundation which hasbeen prepared for it. If
the permanent foundation is not available, it should be stored in its correct upright position on a level
foundation capable of withstanding the weight of the unit without deformation.
CAUTION:
Never store a transformer solely under the jacking steps, on jacks, or on temporary blocking.
Never store the transformer on rollers.
Neverstoretheunitinornearstandingwaterorinareaswith highmoisture,saltlevels, orcorrosive
