Straightpoint BOLT – on line tensiometer for permanent fixture to wire rope and cable

Manufactured, using an integral, high-accuracy, wireless module the BOLT can also be paired with and transmit load data to a Crosby SP Handheld plus (SW-HHP), which will enable you to read up to four simultaneously.

Constructed from aerospace-grade aluminium, the BOLT digital tensiometer is lightweight and easy to handle and operates on wires that are already under tension. Once installed it enables the operator to quickly check tension on cables or wire ropes set at any angle.

Multiple drop tested from 3 metres or 10 feet.

Inclusive of an SW-D dongle, to make on-the-spot calibrations to achieve greater accuracy of 2-3%; standard factory accuracy is 3-5%.

In combination with a Crosby BaseStation, loads can be monitored remotely. The BaseStation transmits data to a cloud software solution, LoadConnect. This software solution has a dashboard that facilitates a user to see live loads, monitor errors, access historical readings, and view analytics and asset management. Added to this, you have the option of SMS alerts sent directly to your mobile device. This combination will provide reduced site visits, improve decision making and safely monitor line tensions from any distance from anywhere in the world.
