Warning!
This screw compressor unit may be top-heavy. Use caution when rigging and handling to prevent
the unit from tipping.
When unpacked, the unit can be lifted with a crane. The unit must be lifted in the lifting eyes on
the unit. Never lift in the lifting eyes on the compressor or the motor separately.
If a motor is mounted, appropriate adjustment must be made in the lifting point to compensate
for the added motor weight. Adjustment of the lifting point must also be made for any extra
weight added to the standard unit such as an external oil cooler. The extra weight will affect the
centre of balance.
Fig. 89
As a minimum the lifting capacity of the crane and the loading capacity of the chains, straps, lift-
ing eyes and shackles must correspond to the weight of the unit + the weight of the electric
motor.
14.6 Preparations before lifting
Before lifting the unit, make sure that straps/chains are properly secured to lifting eyes/shackles
and that the lifting equipment is in good condition.
14.7 Loading
Be very careful not to damage the unit when loading it. Note in particular that the instrumentation
of the unit is very vulnerable to impacts.
