Safety during transport and
installation
To lift a unit, all loose or pivoting parts, e.g. doors and
towbar, shall first be securely fastened.
Do not attach cables, chains or ropes directly to the
lifting eye; apply a crane hook or lifting shackle meeting
local safety regulations. Never allow sharp bends in
lifting cables, chains or ropes.
Helicopter lifting is not allowed.
It is strictly forbidden to dwell or stay in the risk zone
under a lifted load. Never lift the unit over people or
residential areas. Lifting acceleration and retardation
shall be kept within safe limits.
1 Before towing the unit:
- check the towbar, the brake system and the
towing eye. Also check the coupling of the
towing vehicle,
- check the towing and brake capability of the
towing vehicle,
- check that the towbar, jockey wheel or stand leg
is safely locked in the raised position,
- ascertain that the towing eye can swivel freely on
the hook,
- check that the wheels are secure and that the
tyres are in good condition and inflated correctly,
- connect the signalisation cable, check all lights
and connect the pneumatic brake couplers,
- attach the safety break-away cable or safety
chain to the towing vehicle,
- remove wheel chocks, if applied, and disengage
the parking brake.
2 To tow a unit use a towing vehicle of ample
capacity. Refer to the documentation of the towing
vehicle.
3 If the unit is to be backed up by the towing vehicle,
disengage the overrun brake mechanism (if it is not
an automatic mechanism).
4 Never exceed the maximum towing speed of the
unit (mind the local regulations).
5 Place the unit on level ground and apply the parking
brake before disconnecting the unit from the towing
vehicle. Unclip the safety break-away cable or
safety chain. If the unit has no parking brake or
jockey wheel, immobilize the unit by placing
chocks in front of and/or behind the wheels. When
the towbar can be positioned vertically, the locking
device must be applied and kept in good order.
6 To lift heavy parts, a hoist of ample capacity, tested
and approved according to local safety regulations,
shall be used.
7 Lifting hooks, eyes, shackles, etc., shall never be
bent and shall only have stress in line with their
design load axis. The capacity of a lifting device
diminishes when the lifting force is applied at an
angle to its load axis.
8 For maximum safety and efficiency of the lifting
apparatus all lifting members shall be applied as
near to perpendicular as possible. If required, a
lifting beam shall be applied between hoist and
load.
9 Never leave a load hanging on a hoist.
- 8 -
10 A hoist has to be installed in such a way that the
object will be lifted perpendicular. If that is not
possible, the necessary precautions must be taken to
prevent load-swinging, e.g. by using two hoists,
each at approximately the same angle not exceeding
30° from the vertical.
11 Locate the unit away from walls. Take all
precautions to ensure that hot air exhausted from the
engine and driven machine cooling systems cannot
be recirculated. If such hot air is taken in by the
engine or driven machine cooling fan, this may
cause overheating of the unit; if taken in for
combustion, the engine power will be reduced.
12 Generators shall be stalled on an even, solid floor,
in a clean location with sufficient ventilation. If the
floor is not level or can vary in inclination, consult
Atlas Copco.
13 The electrical connections shall correspond to local
codes. The machines shall be earthed and protected
against short circuits by fuses or circuit breakers.
14 Never connect the generator outlets to an
installation which is also connected to a public
mains.
15 Before connecting a load,
corresponding circuit breaker, and check whether
frequency, voltage, current and power factor
comply with the ratings of the generator.
16 Before transportation of the unit, switch off all the
circuit breakers.
