TP-5700 7/934 Section 2 Load and Transport

D A four-point lifting method is necessary to lift the

generator set. To maintain generator balance during

lifting, the lifting apparatus must utilize the four skid

lifting holes mentioned in the previous paragraph.

One method of lifting standby generators uses an

apparatus of hooks and cables joined at a single

rigging point. See Figure 2-2. The use of spreader

bars is necessary with this method to avoid damage

to the set during the lifting procedure. The spreader

bars should be slightly wider than the generator skid

so the set is not damaged by lifting cables and only

vertical force is applied to the skid while lifting. The

generators may also be lifted by placing bars through

the skid lifting holes and attaching hooks to the ends

of the bars. See Figure 2-1. Be s ure the bars are

properly sized for the weight of the generator set.

Precautions must be taken to prevent the lifting hooks

from sliding off the ends of the bars. Spreader bars

may be necessary with this arrangement if lifting

cables are in contact with the set. A specially

designed lifting fixture is often used to lift the larger

standby generators. The fixture usually includes

adjustable cables to adapt to different size generators

and to compensate for unit imbalance. See

Figure 2-3. In all cases, be sure the components of

the lifting device (cables, chains, bars) are properly

sized for the weight of the generator set.
