7.2 Maintenance
7.2.1 TIRAK
®
Hoist
(1) Daily check the primary and BSO secondary
brake.
(2) Daily check for visible part damage.
(3) Keep wire ropes clean and lightly lubricated to
prevent abnormal wear of the wire rope driving
mechanism.
(4) Store the TIRAK hoist at safe and dry places.
(5) If hoist will be rerigged from longer storage, clean
it and oil up all parts.
7.2.2 Wire Ropes
(1) Use only wire ropes, which meet the
manufacturer´s specifications. For details see
pages 7 and 13.
This will ensure the reliable function of the hoist.
(2) To warrant maximum lifetime we recommend:
– The wire rope must be unreeled and reeled in
a straight line (Fig. 40).
– Keep wire ropes clean.
– Lubricate wire ropes regularly with a rag
soaked with oil.
– Never let the wire ropes rub against sharp
edges.
– Always see that the wire rope outlet is not
obstructed.
– Let the free wire rope end untwist to prevent
wire rope from making loops.
– If the wire rope changes direction, it should
be guided by sheaves or rollers to avoid dam-
age.
7.2.3 Motor
a)
The air motor must be continuously greased
by an oiler.
Adjust the oiler set screw so that the air is fed
with approx. 10 drops of oil per minute.
Take care that the oiler is always well filled.

b)
After longer rest periods pour some 30 cm
3
of
rock oil into the supply hose and let the motor run
for 10 to 15 seconds.
Shut off the air supply and bleed all air pres-
sure from the suplly line:
Then pour some 10 cm
3
of oil into the hose and let
he motor run for two seconds to let the oil be well
distributed in the motor, which guarantees for a
better performance and the longevity of the motor.
c)
Before longer rest periods prepare the motor the
same way to prevent rust formation.
Important:
Use hydraulic oils, free of resin or acid, accord-
ing to HLP/HVLP 32.
For damp compressed air, oilers are to be used
that take up water without loosing the lubricant
effect, and that contain anticorrosive additives.
At lower temperatures, especially for outside
works, it may be necessary to use anti-freeze lu-
bricant, according to ISO VG 32 (e. g. ARAL VITAN
DE 32, BP Energol HLP 32, DEA Arcus DLP 32).
7.2.4 BLOCSTOP BSO Secondary Brake
Besides the daily checks, keep all wire rope clean and
lightly lubricated.
