Attaching the anti-two block switch weight
• Attach the anti-two block switch weight (1, Figure 6-60).
This anti-two block switch must not be locked, refer to
Removing the lock, page 6-40.
If two hoist ropes are reeved, you must attach a anti-two
block switch weight to each of the two anti-two block
switches.
Placing a anti-two block switch weight around the hoist
rope
• (A, Figure 6-61) – Pull the safety pin (1) out and fold the
two halves of the weight apart.
• (B) – Place the two halves of the weight around the last
rope line leading upwards.
• Pull the safety pin (1) out and fold the two halves of the
weight back together.
• Make sure the safety pin locks into place and the two
halves of the weight are securely attached to each other.
If two hoist ropes are reeved, you must also place a anti-two
block switch weight around the second hoist rope.
NOTE: If you place the anti-two block switch weight around
the last rope line leading upwards, less rope will
run through the anti-two block switch weight,
especially if there is a high number of reevings per
lifting operation. This rope line will even be at a
standstill if the number of rope lines is even.
This allows you to reduce the wear of the hoist rope
and anti-two block switch weight and prevent
unintentional deactivation procedures that may be
caused by the running hoist rope lifting the anti-two
block switch weight.
Removing the anti-two block switch
This section describes complete removal.
If the hook block is to be attached to the bumper at a later
point, you will need to detach the anti-two block switch
weight from the hoist rope, so that you can unreeve or reeve
when unrigging the hoist rope. You can place the anti-two
block switch weight around the hoist rope again before
driving.
