Twist locks
A spring loaded contact pin and an inductive sensor at each twist
lock are used to control and check the alignment. An electrical
locking system prevents twisting of the twist locks before they
have fully entered the container locking holes. When all four con-
tact pins are depressed, the ALIGNMENT lamp lights up on the
boom. Only then is it permissible to lock the twist-locks.
Locking and indicating the twist-lock position
On each side of the top-lift there is a locking cylinder that, via a
rod, turns the front and rear 90° in the containers locking hole.
Two inductive sensors on each side monitor whether the twist-
locks are locked or released. See illustration below. The activator,
3, activates the sensor at respective end positions. The distance
between activator and sensor at the end position should be 2-3
mm. Sensor 7205 activates the green TWIST-LOCKS LOCKED
lamp which indicates that both sides of the top-lift are locked onto
the container which is thereby ready to be lifted. When lifting, the
ALIGNMENT lamp is extinguished, i.e., the alignment signal
ceases which prevents accidental release of the twist-locks dur-
ing lifting. The electrical locking device also prevents lifting if the
twist-locks are not released or turned 90° in the container’s lock-
ing hole.
Sensor 7204 activates the red TWIST-LOCKS RELEASED lamp.
The attachment can then be lifted from the container.
