5.4 Shortening the lift tube
The lift tube can easily be shortened at the location of use The lift tube must be shortened due to low
ceiling heights or when using different grippers. The length of the lift tube has to be adjusted so that
the vacuum tube lifter

cannot apply suction to the floor, but is able to safely deposit the load on
the floor at any time.
Tools required:
Knife
Bolt cutter
Insulating tape (approx. 30 mm wide, not permeable to air)
Size 13 open-ended wrench
Multipurpose grease
Procedure for shortening the lift tube:
Tube lifter must be suspended (Figure 1)
Remove the adhesive tape from the lift tube.
Twist the lift tube off of the tube holder.
Cut the lift tube at the desired position using a box
cutter; cut off the wire spiral using the bolt cutter.
To facilitate the mounting of the lift tube, spread the
multipurpose grease on the inside of the operator
handle (Figure 2).
Twist the lift tube completely onto the winding of the
operator handle. Twist on the lift tube until it
completely covers the threads of the operator
handle (Figure 3, 4)
Wrap the lift tube using adhesive tape (Coroplast)
so that the cover of the operator handle is sealed
(wrap adhesive tape around the entire lift tube
approx. 2x) (Figure 5)

Due to the lift tube reinforcement on the underside of the lift tube, the lift tube
may only be shortened at the rotary union (top).
Tube lifter stroke = approx. 0.7 x length of the lift tube (unloaded). The tube lifter
must be disconnected before the lift tube can be shortened at the rotary union.
Attention: When the lift tube is shortened, the lifting distance is also shortened.
