blocstop™ BSO - O. Rosinski GmbH

the rope runs through a secondary brake mounted on-site,
for example.
The independent secondary brake must be mounted in such a
way that the direction (A) in which the rope runs through the
independent secondary brake at the time of the malfunction is
opposite to the braking direction (B).
This protects the hoisting gear / load lifting equipment against the
following damage:
Suspension rope break
Hoist malfunctions (broken gears)
Press the EMERGENCY-STOP button to manually trigger the
independent secondary brake in an emergency situation.
4.2 Components / Modules
See Fig. 1.
Item Name Function
1 Safety rope
2 Hand-lever Independent secondary brake release
3 EMERGENCY-
STOP button
Manually activates the independent
secondary brake
4 Inspection window Enables visual inspection of the function
of the centrifugal force mechanism during
operation
5 Centrifugal force
weight
Permanently monitors wire rope speed
during the run. The clamping jaw mechanism
will be activated if the speed setting
is exceeded.
6 Clamping jaws Mechanical connection to the wire rope in
emergency-stop and activation situations.
The greater the tractive force, the tighter
the clamping effect will be.
7 Limit switches Optional
8 Securing holes Holds the bolts / screws used for securing
the independent secondary brake to the
anchoring devices
9 Control pin BSO 2050/2360 only: Visible when the
safety rope is running in correctly.

4.5 Circuit diagram
The hoist's circuit diagram is located in the terminal box of the
motor.
See '10.3 Assembly, Independent secondary brakes with limit
switch: Electrical connection' on page 10.
4.6 Safety equipment
Press the EMERGENCY-STOP button to manually trigger the
independent secondary brake in an emergency situation.
Optional for independent secondary brake with electrical deactivation:
The limit switch will ensure that the control voltage for the downward
movement will be disconnected if an emergency-stop is
activated.
4.7 Anchoring
DANGER!
Danger of severe injuries caused by incorrect anchoring!
High-strength, galvanised bolts and screws can become brittle
and break. Risk of falling and of being injured by falling objects!
– High-strength galvanised bolts / screws (10.9 or 12.9)
may not be utilised for anchoring.
– Utilise bolts / screws with the specified strength.
Specifications detailing the strength of the bolts / screws are
listed in Table 1 on page II.
Observe the details in 'Structural requirements' on page 6.
The independent secondary brake must be secured in place so
that the rope runs vertically into the independent secondary
brake from above. The independent secondary brake must be
aligned so that it does not touch the rope. The rope must be
tensioned using a tensioning weight or a relevant winding device.
The required load bearing capability rating of the suspension and
securing modules depends on the independent secondary brake
model.
