2.3 Secondary Brakes
The blocstop
™
BSO overspeed locking device
(D) – hereafter called BSO secondary brake
– stops the descent immediately in case of
accelerating overspeed.
The blocstop
™ BS/BSO overspeed and slack
wire rope locking device (E) – here-after
called BS/BSO secondary brake – additionally
provides protection against slack wire rope or
primary wire rope failure, when using second-
ary wire ropes.
SECONDARY BRAKES MUST ALWAYS BE
ATTACHED AND USED.
2.4 Emergency Descent
without
power
tirak ™ hoists are equipped with a mechanical
centrifugal braking system, permitting a descent
at moderate speed in case of emergency. No
handcranking is needed.
2.5 Wire Rope Driving Mechanism
The wire rope enters the hoist from the top,
is led through by the patented driving system,
and exits opposite its entry. As the wire rope is
not stored inside the hoist, its length (i. e. the
possible rope travel) is unlimited on principle.
The driving system is independent of the load
applied to the wire rope. The whole mechanism
is housed in an aluminum casing.
2.6 Wire Rope
tirak
™
hoists use a Special tirak
™
Wire Rope
(see chapter 4). Unless speci fi cly speci fi ed in
writing by the manufacturer, only this special
tirak ™ Wire Rope may be used.
NOTE: The manufacturer declines all re-
sponsibility for machines used with
a wire rope other than speci fi ed by
them in writing.
1) For all hoists pendant control and pushbutton control are available
on request.
