Crosby Su6674 Bolt Bolt On Line Tensiometer User Manual (+ PDF)

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

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.

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

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.

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.
