BOLT On Line Tensiometer
PLEASE NOTE THAT CROSBY|STRAIGHTPOINT ACCEPT NO RESPONSIBILITY FOR ANY ERRORS OR OMISSIONS WITHIN THIS MANUAL.
Introduction
‘BOLT’ is used to measure the tension on a wire rope by clamping the device on
to a wire rope using the two bolts.
Unless specified while ordering, the BOLTs are calibrated as a standard with
32mm wire rope to 10te WLL.
BOLT can only be used on specific wire rope diameter with which it is
calibrated for; this info will be provided on the calibration certificate.
Every BOLT is supplied with a USB dongle for the user to perform an onsite
calibration for better accuracy.
For detailed calibration procedure contact SP distributor.
It is recommended to perform an onsite calibration to achieve an accuracy
level of 2-3% FS or if the wire rope diameter is different to the one
calibrated from factory.
NOTE: It is the responsibility of the end user to ensure the BOLT is
calibrated to the correct wire rope diameter to achieve the required accuracy.
Fitting the batteries
IN A SAFE AREA ONLY, remove the side cover of the BOLT using a flat blade
screwdriver.
Fit batteries and refit cover.
The BOLT may be connected to the Straightpoint SW-HHP ATEX handheld, in
hazardous areas, or to our range of load monitoring software that is not
covered in this manual.
Warning: Make sure batteries are fitted correctly and that the polarity is
correct.
To Clamp a BOLT
BOLT can be used on a range of wire rope of diameters from 16-32mm.
Remove the two M10 bolts of the device place the device under the rope being measured attach the top clamp and tighten the bolts.
To Clamp a BOLT (contd.)
Make sure the bolts are torqued up equally, the torque rating is provided on
the calibration certificate.
Note: It is important that the two bolts are tightened equally, if not it
could show incorrect readings
Wire Rope Diameters
| Wire rope diameter (mm) | Torque setting (Nm) |
|---|---|
| 32 | 30 |
| 26 | 20 |
| 16 | 10 |
In case using a wire rope diameter different to the calibrated one, torque it
until the rope is in contact with BOLT body and use a torque wrench to measure
the torque value.
After calibration make sure the BOLT is tightened to the same torque value.
It is recommended to perform periodic checks on the BOLT including visual
inspection and making sure the bolts are torqued correctly.
NOTE: Care to be taken not to drop the sheave or bolts while working at a
height
