L
1
= depth in concrete of TR8 – please refer to section 6 INSTALLATION – CEILING UNIT or
height of the wooden beam
L
C
= depth in concrete of lifting mechanism – please refer to section 6 INSTALLATION –
CEILING UNIT
L

=L – 55mm
L

= distance above wooden beam. Due to security buffer minimum 40mm.
Practical example CONCRETE:
Lower ceiling is 150mm below the main concrete. Concrete type is C25/30. (see
concrete types and strengths
in 6 INSTALLATION – CEILING UNIT).

Maximum length of the 4 threaded bars is 135mm.
Practical example WOODEN BEAM:
Lower ceiling is 150mm below the main wooden beam. Wooden beam is
100x100mm.
