‘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.

To Clamp a BOLT (contd.)
Note: It is important that the two bolts are tightened equally, if not it could show incorrect readings

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
