4.0 Structure and function
4.3 Brief description
The Telemag is an electric telescopic pillar with guiding
tubes.
The pillar is used in a complete system and is used exclu-
sively for dynamic centric compression- or eccentric com-
pression-loaded lifting movements.
The telescopic pillar consists of two or three nested guide
tubes which are extended and retracted by an integrated drive.
The guide slide bearings ensure extension and retraction
evenwitho-centeredloads.
Direct current motor with a worm gear drives a threaded
spindle. A threaded nut, which is permanently connected to
the actuator, runs up and down on the spindle and gener-
ates the feed motion. The slide tube is connected on the
front side via the base plate to the guide tubes.
Extension or retraction of the telescopic tube occurs by
changing the rotational direction of the motor. The thrust
speed is dependant on the load.

element
The Telemag telescopic pillar requires an external control to
power the motor unit. It is connected to the THG/TLG via a
connecting cable and to the TLT via two connecting cables.
THG/TLG
ThemaindierencebetweentheTHG/TLGandTLTtele-
scopicpillarsisofthedierentsizesoftheguidetubeand
the number of spindles (refer to chapter 3 Technical data).
The magnitude of the load speed and transverse force de-
termines the choice of drive motors and their power. This ul-
timately results in the deviations in the values for compres-
sive forces and thrust speed as well as additional functions
such as cable feedthroughs.
TLT1
Compared to the Telemag THG and TLG telescopic pillars,
two spindle systems in the TLT telescopic pillar produce
double the thrust speed. There are two connection cables
for two DC motors permanently installed on the TLT tele-
scopic pillar.
NOTE
Additional differences between the THG, TLG and TLT telescopic
pillars are found in the sections on connections and data
sheets in the Appendix.
TLT2
Compared to TLT1, the TLT2 has placed the 2 DC Motors
and Electronic connection outside of the tube to support a
reduced Built in Dimension.
