Layher Uni Light Tower
Dismantling
To remove the different parts open the snap-on
claws by depressing the locking clips. The red claws
of the decks enable a single person to assemble or
dismantle them easily; open them at one end and
rest the base of the clips on the rung. Now open the
opposite clips and remove the deck.
Dismantling is carried out in the reverse order of
assembly.

elements only after having taken down the
ladder frames

situated above.
During assembly and dismantling, system decks or scaffold planks according to DIN 4420-3 (minimum measurement: 28 x 4.5 x 220 cm long) must be built in as
auxiliary decks at maximum height intervals of 2.0 m. These auxiliary decks, providing a safe footing for assembly and dismantling, are removed after the erection.
Each platform must be completely boarded.

Operating the castors
During assembly and while working, the castors
9
must be kept locked by pressing down the brake
lever labelled STOP.
When the brake is locked, the lever labelled STOP
is in the down position. For movement, the castors
are unlocked by pushing the other lever down.
Wall support
under load
For work performed on a load-bearing wall,
ballasting can be reduced in accordance with
the ballasting table (see page 5). In this case,
wall supports must be installed on both sides of
the tower. Use a Uni-distance-tube
14
and fix it
to the ladder frame
1
,
1a
with the couplers
15
.
The mobile beams are to be mounted so that the
extension arms project from the side opposite to the
wall. The wall supports must be attached at the
height of the top working platform or at most 1 m
below that.
