22. Mounting rail onto the pipe
Before positioning a rail onto the pipe, position the magnetic or resistive bridges in a
proper distance from the rail guide according to Table 1.
To change the value of ‘M’ on the pitch, rotate the M12x3 feed screw on the fixing
mechanism using 5 mm hex wrench.
IMPORTANT! Right rotation increases the distance from the pipe (dismounting),
while left rotation decreases the distance and mounts the rail on the pipe.
1.12 Mounting ring rail
a) Set one or two bridges to the ‘M’ value of 2 mm lower than Table 1
recommends, which will allow the rail to be mounted onto the pipe.
b) Place the ring rail in open configuration (with mounting catch unlocked and two
M6 screws loosened) onto the pipe.
c) Mount the catch and tighten two M6 screws.
d) Press the bridges to the pipe by rotating the M12x3 feed screw left to achieve
the recommended ‘M’ value on the pitch. If the rail is not mounted tight,
increase the ‘M’ value.
e) Place the carriage onto the rail with the rotational rollers set according to
information from the point “Preparing to operation on the orbital rail”.
f) 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.
1.13 Mounting sectional rail (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.
b) Place the rail segment in open configuration (with magnetic bridges in position
OFF and two M6 set screws loosened) in required position and toggle the
magnetic bridge levers to ON.
c) Place the next rail segment in open configuration (with levers of 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. Then, mount the catch, tighten
two M6 screws, and toggle the magnetic bridge levers to ON.
d) Assemble consecutive segments in the same way.
