Ladders > Triple Extension Ladders
The ARION7TX-RO is a 7 metre Aluminium Triple Extension Fire/Rescue Ladder comprising of
three ladder sections operated by a single rope hauling line. The ladder is tested & certified to
BS-EN1147, Ladders for Fire Service Use as a 3-Person Fire/Rescue Ladder.
Pawling of the ladder is achieved with ‘fully automatic pawls’, both of which are located on
each side of the ladder top section & mid section near the base of the ladder. These pawls
interact audibly with each rung to enable rung counting to assist with ladder extension height in low light conditions. They are simply actuated by allowing the pawls to pass the rung of choice, bring them back down past the rung & then up to have them click into place. The mid section of the ladder follows the lead of the top or ‘fly’ section so pawling will take place at the same time. The Automatic Pawls allow for maximum foot area, (no additional pawl axle) & negate the need for double rope pawling. The ladder rungs are fully ribbed for maximum boot grip.
The ladder is equipped with a rope safety device or ‘Automatic Arrest Device’, (AAD). This
sprung cam arrangement is located on the top of the base section where the rope passes
through the top pulley. In the case of a sudden unintentional rope release while deploying or
stowing the ladder, the sprung cam interacts with the rope locking it into place.
The top or ‘fly’ section & mid section of the ladder extends from the front of the ladder & all
rope work is carried out from the back of the ladder. The ladder is equipped with solid rubber
feet with swivel feet available.
