Petzl Avao Wind Turbine Harness?

Following a move to the use of triple action connectors in the wind turbine industry, Petzl will soon be offering a couple of their Avao Full Body harnesses with triple action (triact) karabiners. Two new Avao Bod harnesses are due to be released in February 2014 which will appeal for those looking for a Wind Turbine harness, but these will also appeal to Riggers and the black version to Military:

Petzl Avao Bod (International ANSI) harness with Triact Karabiner

Petzl Avao Bod ANSI International Wind Turbine Harness

Petzl Avao Bod Fast in Black (International ANSI) harness with Triact Karabiner

Black Petzl C71AFN Avao Bod Fast Military Harness

Both harnesses are based on the standard Petzl Avao Bod harness but are the international version so feature fall indicators (as well as the triple action karabiner connecting the top harness to the sit harness). The Avaos are suitable for all types of work: work positioning, work restraint and fall arrest.

New product review – ISC D4 Descender

We have been lucky to get our hands on a new descender which has been developed by ISC for the rope access market, the D4 Descender.

The device is made from a high grade aluminium and has a stainless steel cam which should ensure a good degree of longevity.  The device ‘fails to safe’ (the device locks if the handle is released) and also has a panic feature (if the handle is pulled down in panic then it locks the device – we found this panic feature is not a hyper-sensitive as some others on competitor products).

ISC D4 Descender

The D4’s other selling points are that it is rated to 240kg and does not require extra friction to operate at the top end of its range. Operationally the D4 has a smooth rope run through the device and when the user is not in full suspension, such as if working on an incline (like an embankment), the design allows the cam to be squeezed open using your thumb to allow rope to feed through gently (no need to operate the handle). Finally, the D4 works well in a belay mode as well as when put into a system such as a Z rig.

New Petzl Zigzag for 2014

Petzl have just released detailed information about the new Zigzag mechanical prusik. Based on the very popular first version but with slight design changes, it is likely to be very popular with arborists.

Petzl Zigzag

The main changes include strengthened side plates and resigned attachment holes to help keep the karabiners loaded correctly on their major axis. The attachment hole at the rope end also now has a flexible elastomer ring that helps keep the karabiner orientated to its optimal working position (reducing the risk of poor positioning and the cantilever effect that occurred with the previous Zigzag). The harness end attachment ring has also been enlarged to reduce the risk of poor karabiner positioning and prevent the karabiner sleeves from snagging. Even with these changes, as with most devices, it is imperative that the user is vigilant about the karabiner positioning. Other minor changes includes extended side plates to help guide the rope in the sheave. They are also now flared to ensure smooth operation even if the rope rubs on the side plates.


– The changes above were tested and approved using the Petzl OK Triact (Triple action) and Am’D Triact Ball-Lock karabiners. Other karabiner models of similar shape may be used, but their compatibility must be verified by the

Petzl ASAP Lock – Available 2014

Further to our post last week about a new Petzl ASAP which has just been shown at the IRATA meeting in Las Vegas, we are pleased to give you the first glimpse of the Petzl ASAP Lock Fall Arrester:

Petzl ASAP Lock Fall Arrester

The ASAP Lock is based around the very popular Petzl ASAP fall arrest device featuring a toothed wheel which allows the device to run up and down the rope without manual interference. If the device is shockloaded or gains too much inertia (such as during a mainline failure), the wheel locks on the rope arresting the fall of the user. The ASAP can be used with or without a tear out lanyard and has a connection arm offering a semi-permanent connection, helping minimise the risk of dropping the device when putting it on / removing it from the rope.

The locking function of the ASAP LOCK immobilizes the fall arrester on the rope, reducing the length of the fall

The connection arm of the ASAP LOCK makes the system drop-proof when passing intermediate anchors.
