2.9b Line riding tensiometer
installation on a swing arm
1. Verify that the line riding tensiometer size fits
with the wire rope diameter.
Table: Line riding tensiometer part number and rope diamater.
2. Identify the hoist rope and choose a proper
place, normally as far up the butt section as
practical, to install the swing arm.
3. Install the swing arm by welding, bolting or
strapping it to the boom. It should be located to
be as centered as possible with the boom end
sheave and positioned such that neither the
swing arm nor the line riding tensiometer
interfere with the hoist rope or other objects.
4. Remove top sheaves and top bolts & spacers
from the line riding tensiometer*. Place the line
riding tensiometer on the unloaded hoist rope,
oriented such that the transmitter antenna is on
the cab side and the swing arm holes are
directed to the boom top. Re-install bolts and
sheaves.
5. Attach the swing arm end to the line riding
tensiometer.
6. Verify that the angle the swing arm forms with
the boom is not too large and that nothing limits
free displacement of the swing arm and line
riding tensiometer assembly at any boom angle
or configuration. Extend the swing arm as
needed.
7. If the line riding tensiometer has been supplied
with rope payout, ensure that both proximity
switches (led) operate as the appropriate
sheave turns.
8. Verify that the sensor antenna is not curved.
9. Verify that all bolts are tight.
10.Operate the hoist to verify correct line riding
tensiometer function.
11. Proceed to load pin / Line riding tensiometer
calibration of the display/receiver (see Line
Riding tensiometer Calibration section).

* The hoist rope can also be installed by passing
the wire rope around the pulleys when the hook
does not interfere.
