4.2 Brief description
The functional principle of the telescopic pillar CPMT is based on a
push or pull force for the movement of centric and eccentric loads.
The CPMT requires an external controller for it to be operational.
A DC gear motor attached to the middle tube drives two spindle
nuts simultaneously via a spur gear. The rotation of the nuts induces
a linear motion of the two ballscrews in opposing directions. The
ballscrews are attached to the base plates and cause an extension or
retraction of the telescopic tubes depending on the direction of
motion. A built-in brake holds the position at a standstill or during
power cut.

Structure and function
Outer tube base plate (a1)
The outer tube base plate has four holes to access attachment bores
in the outer tube (b1) for the mounting screws. This enables the pil-
lar to be fastened to one side of the application. The outer tube base
plate must be attached permanently with fastenings screws M10 to
a metal plate in the application, which has to support the areas of
force distribution (c1, c2).
Motor cable (a2)
The cable (a2) exits to one side at the outer tube base plate (a1) and
has to be connected to an external control unit via the DIN-8 plug or
the flying leads cable attached.
Outer tube (a3)
The outer tube is the tube with the largest outside dimensions. The
CPMT pillar can be mounted in any orientation to place the outer
tube (a3) at the top or bottom of the application.
Middle tube (a4)
The middle tube is the tube between the outer and inner tubes.
Inner tube (a5)
The inner tube is the tube with the smallest outside dimensions. The
CPMT pillar can be mounted in any orientation to place the inner
tube (a5) at the top or bottom of the application.
Rim covers (a6)
The purpose of the rim covers for the outer and middle tube is to
protect the tube guiding system from dust and to prevent the
ingress of foreign matter. The rim covers must not be removed
under any circumstances.
Glide pads (a7)
The purpose of the glide pads (a7) is to provide a stiff, virtually play-
free guiding of the tube sets.
Inner tube base plate (a8)
The inner tube base plate has four holes to access attachment bores
in the inner tube (b1) for the mounting screws. Its purpose is to fas-
ten the pillar to one side of the application. The inner tube base plate
