e) Press the bridges to the pipe by rotating the M12x3 feed screw left to the
recommended value of ‘M’ on the pitch. If the rail is not mounted tight,
increase the ‘M’ value.
f) Place the carriage onto the rail with the rotational rollers set according to
information from the point “Preparing to operation on the orbital rail”.
g) Manually or mechanically rotate the carriage by one full turn to check whether
the torch is in a constant distance from the pipe that will enable proper
operation. If the distance is not constant, correct the value of ‘M’ on
appropriate bridges.
1.14 Mounting flexible rail onto pipe (two persons required)
a) Set one bridge to the ‘M’ value of 2 mm lower than Table 1 recommends,
which will allow the rail to be mounted onto the pipe. Length and number of
rails are also specified in Table 1.
b) Place the rail segment in open configuration (with magnetic bridges in position
OFF and two M6 set screws loosened) onto the pipe in required position and
by pressing the guide to the pipe, toggle the magnetic bridge levers to ON.
c) Place the next rail segment in open configuration (with magnetic bridges in
position OFF and two M6 set screws loosened) onto the pipe in a way to
contact the faces of both rail guides.
d) Tighten two M6 screws.
e) Press the guide to the pipe and toggle the magnetic bridge levers to ON.
f) Assemble consecutive segments in the same way.
g) Press the bridges to the pipe by rotating the M12x3 feed screw left to the
recommended value of ‘M’ on the pitch. If the rail is not mounted tight,
increase the ‘M’ value.
h) Place the carriage onto the rail with the rotational rollers set according to
information from the point “Preparing to operation on the orbital rail”.
i) Manually or mechanically rotate the carriage by one full turn to check whether
the torch is in a constant distance from the pipe that will enable proper
operation. If the distance is not constant, correct the value of ‘M’ on
appropriate bridges.
