Straightpoint Cablesafe Rope Tension Meters

Rope Tension Meter from Straightpoint

The CableSafe is the continued evolution of Crosby Straightpoint’s running line tensiometers. When used in the field, it will allow the user to monitor tension with exceedingly high levels of accuracy, which ensures rope/cables do not become overstretched or break.

When using a capstan winch to unwind electrical cable from a reel/spool, you will be able to integrate the CableSafe within this setup to ensure that it is being pulled at a safe tension level. This helps the line maintain its transmission capability, prevents it from becoming a fire hazard risk, and also stops the need for further work in order to remove and replace it. The contractor is gifted with decreased liability, dramatically increasing peace of mind.

Using CableSafe on cable pulls reduces liabilities on cable installations, making it ideal for the following applications:

• Measure tension when pulling electrical cables – protect against fractures or elongation
• Measuring tension on a synthetic rope when erecting delicate structures using gin poles and a capstan winch

Another example of best use is during the installation of cell phone towers or similar delicate structures. The product helps ensure structure-to-ground ropes which are connected to a gin pole and pully system. Do not exceed maximum tension whilst lifting sections of the tower to the top because there is the possibility of the rope becoming snagged, causing greater tension to be loaded upon the system. With heavy materials being lifted to great heights, this would create a major safety hazard, leading to a catastrophic failure, endangering lives. Avoid the unknown through accurate monitoring, especially when risks are high.

What distinguishes it, apart from previous versions of this type, is the developed lightweight design, allowing easy transportation and usage. Providing up to 500 hours battery life, you can be assured there will not be any loss of power before your work day has ended. High-level IP67 or NEMA6 ingress protection allows it to be used in a variety of heavy weather conditions and dusty environments.

These features, as a collective, mean that it will be an invaluable and reliable tool in your work-related armoury.

The five-wheel design and gravity catches, with top sheave pins, allow for fast and simple rope attachment set-up. The accuracy is further improved over three-wheel alternatives.

When used with a cable/rope pulling device, you can remotely monitor the tension on the line using your smart handheld device via a Bluetooth connection*. With the operator locating themselves up to 100m or 328ft away from the CableSafe, it will allow them to survey job progress at a safe distance.

*The ‘HHP’ app is available to download for free (Android/iOS) and is compatible with all SP Bluetooth Products.
