Installation and operating manual
ATTENTION!
Incorrect assembly!
Damage to the rope may occur!
–
The rope must never run over an edge!
–
The loose rope end must hang free.
Note
Do not mix up the safety rope and the suspension rope: Observe
the correct rope diameter (see also Fig. 4).
–
Roll-off the rope correctly so that no loops in the rope occur.
–
Secure the rope to the suspended assembly. The rope must
hang free.
–
Open the independent secondary brake by pressing down
on the manual lever.
–
Feed the rope in from the top.
BSO 2050/2360: The control pin will spring out if the rope
has been fed in correctly.
–
Manually pull the rope until it is taut.
–
Clamp two tension weights (weighing approx. 11.5 kg) in
place about 20 cm above the ground (see Fig. 6).
–
Place the loose end of the rope down correctly to prevent
any loops or knots from being created.
Independent secondary brakes with limit
switch: Electrical connection
The limit switch will ensure that the control voltage for the down-
ward movement will be disconnected if an emergency-stop is
activated.
See Fig. 11.
Connection diagram for independent secondary brakes with limit
switch.
The switch must be connected as a break contact in order to
realise forced opening.
–
Utilise the colours BK (black) and BKWH (black-white) for
the connection.
Limit switch cable with plug connection
–
Connect the limit switch cable plug to the hoist's control box.
Hard-wired connection
Only a qualified electrician is permitted to undertake this work.
–
Connect the limit switch cable inside the hoist's control box
as shown in the circuit diagram.
EN-10
10.4 Commissioning
Determine operational readiness
–
Check the rope anchoring.
–
Inspect the connection between the independent secondary
brake and the load lifting equipment.
–
Check whether the rope enters the independent secondary
brake vertically.
–
Check whether the independent secondary brake can freely
align with the rope.
–
Record the inspection results in the logbook.
Functional test
See Fig. 10 (example).
General function test:
–
Inspect the housing for signs of damage.
–
Press the EMERGENCY-STOP (1) button while moving
downward.
The independent secondary brake must close and hold the
rope.
Optional for independent secondary brakes equipped with a
limit switch:
The hoisting gear may not move downwards.
–
Open the independent secondary brake: Turn the manual
lever (2) clockwise until it latches into place.
Check the function of the centrifugal force weight:
–
Check the inspection window (4) during every run to see
whether the centrifugal force weight is turning.
Check the activation of the independent secondary brake:
The function of the speed limitation can be checked using two
different tests. The testing method depends on how the inde-
pendent secondary brake is installed.
Method 1: The independent secondary brake is removed,
raised approx. 30 cm and allowed to fall on the (vertical)
rope. The falling path may not be obstructed by any on-site
components which could collide with the independent sec-
ondary brake.
Method 2: The safety rope is abruptly jerked through the
independent secondary brake by hand.
Method 1 (Checking the speed limitation):
DANGER!
Danger of being injured by falling objects! Danger of
crushing and cutting!
When performing the following test there is a risk of being
crushed between and cut by the falling independent secon-
dary brake and the on-site components.
–
Do not reach into the falling path of the independent
secondary brake.
