4.3 PNEUMATIC CHAIN HOIST WITH TROLLEY
The devices are delivered as pre-installed and are designed for the beam
range A or B specifi ed on the ratings plate. Before installing the chain
hoist, make sure that the track beam is within the desired adjustment
range (see Tab. 1).
In 1-strand configuration the top hook is to be installed centred on the
marking “1/1” on the mainframe assy, in 2-strand configuration centred
on the marking “2/1”. In 3- and 4-strand configurations, the top hook is to
be installed centred on the marking “1/1” on the main frame assembly.
Attention:
Screw the locking plate back on after installation.
The supporting structure must be dimensioned in such a way that the
total operating forces can be safely absorbed.
Assembly of the trolley 2-6 t (compare Fig. 11)
1. Unscrew the locking nuts (item 9) and hex nuts (item 2) from the
beams (item 1) and remove both side plates (item 6) from the trolley.
2. Measure the fl ange width of the beam (measure b).
Fig. 10
3. Adjust measure “B” between the shoulders of the round nuts (item
5) on the threaded beams (item 1).
Ensure that the 4 holes in the roundnuts face towards the outside. The
distance “B” between the shoulders of the round nuts on the beams
should be selected so that it corresponds to the dimension “B” of the
fl ange width “b” plus 4 mm lateral clearance (dimension “A” on each side
is 2 mm). Ensure that the centre beam is centred between the round nuts.
4. Replace one side plate (item 6):
Replace one side plate ensuring that the locking sleeves (item 8) engage
into one of the 4 holes in the round nuts (item 5). To achieve this it may
be necessary to rotate/adjust the round nuts slightly.
5. Replace the washers (item 3) and tighten the hex nuts (item 2).
Finally, screw on the lock nuts (item 9) by hand and tighten by 1/4 to
1/2 rotation.
Attention:
The lock nuts must always be fi tted!
