Pneumatic chain hoist CPA ATEX
6. Loosely replace the second side plate (item 6) on the beams (item 1).
The washers (item 3), hex nuts (item 2) and lock nuts (item 9) can be
fi tted loosely.
7. Placing the entire pre-assembled unit onto the track beam.
8. Placement of the second side plate:
Here, the locking sleeves punched into the side plate must meet up with
one of the existing four holes in the round nuts. To achieve this it may
be necessary to rotate/adjust the round nuts slightly.
9. Tighten the hex nuts on the second side plate:
Then tighten the lock nuts by hand and then a further ¼ to ½ turn.
Attention:
The lock nuts must always be fi tted!
10. The following should be checked by moving the entire assembled unit:
• that a clearance of 2 mm is maintained on each side between the
plain roller fl anges and the beam outer edge.
• that the centre beam and consequently the lifting device is centred
below the beam.
• that all 4 lock nuts are fi tted.
• that the side plates are parallel.
• that all plain rollers roll freely and make good contact with the
beam flange.
• that there are no obstacles on the beam flange.
Assembly of the trolley 7.5-10t (see Fig. 12 and 13)
1. Measure the fl ange width of the beam.
2. Evenly distribute the spacer sleeves and spacer washers on both sides
of the beam.
A clearance of 2 mm between the wheel fl ange and the beam fl ange
must be maintained (inner dimension = fl ange width + 4 mm).
Attention:
When installing the beam ensure that the spacer sleeve
for the supporting frame is present (Fig. 11 and 12).
3. After adjustment of the inner dimension, evenly distribute the remain-
ing spacer washers on the outside of the side plates on the beam.
There must be at least 3 small washers (3 mm) and 1 large washer
(3 mm) between the side plate and the crown nut.
Tip:
For easier mounting, screw one side plate tightly.
Pay attention to the desired position of the drive side. The other side
plate is attached loosely.
4. Then lift the entire unit to the beam and tighten all crown nuts.
5. Secure all crown nuts with cotter pins.
6. The following should be checked by moving the entire assembled unit:
• that a clearance of 2 mm (“dimension A”) is maintained on each side
between the plain roller flanges and the beam’s outer edge.
• that the centre beam and consequently the lifting device is centred
below the beam.
• that both lock nuts are fitted and secured with cotter pins.
• There must be at least 3 small washers (3 mm) and 1 large washer
(3 mm) between the side plate and the crown nut.
• that the side plates are parallel.
• that all plain rollers roll freely and make good contact with the beam
flange.
• that there are no obstacles on the beam flange.
Assembly of the hand chain (VTG trolleys with geared trolley only)
To fi t the hand chain position the slot on the outer edge of the hand
chain wheel below the hand chain guide.
Place any one link of the endless hand chain vertically into the slot and
turn the hand chain wheel until the link has passed the chain guides
on both sides.
Fig. 13
Attention:
Do not twist the hand chain when fi tting!
Geared trolleys are moved by pulling the hand chain.
Shortening or extending the hand chain (CPA Models with geared
trolley only)
The length of the hand chain should be adjusted so that the distance to
the fl oor is 500 - 1000 mm.
1. Look for the open link in the hand chain and open it by bending.
