Crosby SU6674 BOLT Bolt On Line Tensiometer
Product Information
Product Name: BOLT Bolt On-Line Tensiometer
Manufacturer: Crosby|Straightpoint
Part Number: SU6674
Version: v1.00
Product Usage Instructions
Fitting the batteries:
- Make sure you are in a safe area.
- Using a flat blade screwdriver, remove the side cover of the BOLT.
- Insert the batteries correctly.
- Refit the side cover.
- Warning: Ensure the batteries are fitted correctly with the correct polarity.
To Clamp a BOLT:
- BOLT can be used on wire ropes with diameters ranging from 16mm to 32mm.
- Remove the two M10 bolts of the device.
- Place the device under the wire rope being measured.
- Attach the top clamp and tighten the bolts.
Note:
It is important to tighten the two bolts equally to avoid incorrect readings.
Wire Rope Diameters:
| Wire Rope Diameter (mm) | Torque Setting (Nm) |
|---|---|
| 32 | 30 |
| 26 | 20 |
| 16 | 10 |
If you are using a wire rope diameter different from the calibrated one,
torque it until the rope is in contact with the 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 ensuring the bolts are torqued correctly.
NOTE: Take care not to drop the sheave or bolts while working at a height.

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.
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
