2.6.1.2 Load table - indirect tension
2.6.2 Two-button actuation
The fact that two buttons always need to be pushed in the correct
sequence means that, as far as possible, inadvertent actuation of the
remote control is excluded (see chapter 5 “Releasing the load by radio”
on page 5 - 22).
2.6.3 Opening safety device
Opening safety device with (residual) loads over 55 lbs by spring force.
If, nevertheless, actuation of the release mechanism on the LUDWIG
HOOK occurs, and the locking pin moves upwards, the special
geometry of the LUDWIG HOOK ensures that the hook does not open
far enough, with loads in excess of 55 lbs, to release the load. The load
will remain hanging from the unlocked LUDWIG HOOK.
2.6.4 Power failure
Power failure with (residual) loads over approx. 55 lbs. Actuation of the
remote control at this point in time has no effect. The load continues to
hang safely from the locked LUDWIG HOOK (see chapter 5 “Carry out
a function test over 55 lbs” on page 5 - 17).
