The L27A-XS 3.0 is the latest product in the successful Rosenbauer XS series and, with a working height of exactly 27.6 m, rounds off the range of articulated turntable ladders from Karlsruhe.

The abbreviation XS (for ‘extra small’) refers to the special construction of these turntable ladders with a tiltable cage arm and an inwardly offset swivel joint, which means that they can be used to their full extent even in very tight spaces. In addition, generation 3.0 of XS technology stands for maximum performance, security and connectivity.

Restricted space conditions

The large radius of action is one of the many advantages of the L27A-XS. It can be brought up to 5.90 m from an instructor object and still offers full performance with maximum payload (five people in the basket). This makes it easier to compensate for a set-up error in the case of a low rescue height or in a horizontal escape and the smaller distance can also be used tactically to ensure the success of the mission under restricted space conditions.

Like all Rosenbauer turntable ladders in the XS series, the new L27A-XS is also equipped with a 3.0 generation control

In addition, the L27A-XS covers wide building fronts with its projection. This makes it easier to set up and position, because it does not have to be relocated or repositioned if several deployment sites are to be approached at different heights. Like all Rosenbauer turntable ladders in the XS series, the new L27A-XS is also equipped with a 3.0 generation control.

Additional assistance systems

This provides around ten times more computing power than its predecessor and meets both the safety integrity level "SIL 2, Category 3, Performance Level D" according to IEC 61508 (functional safety of programmable, electronic systems) and the machine directive EN 13849. In addition, the new control system with up to five can buses offers sufficient connectivity to equip XS ladders with the latest headlight and camera systems, additional assistance systems and extensive automatic functions.

The L27A-XS is built on a 2-axle chassis from Mercedes Benz (Atego 1527 F) with a gross vehicle weight of 15 t. The ladder set consists of a five-part main arm with a tiltable cage arm (4.35 m), a horizontal-vertical support with a width of up to 4.80 m ensures a solid stand.

Basket water duct

The first vehicle goes to the La Rochelle fire brigade in France and has a compact bogie

With a permanently mounted aluminum tube in the upper ladder, a water duct integrated into the basket structure, man protection nozzles in the basket floor and two turrets, which are held in the equipment rooms and, if necessary, attached to the basket water duct, it has basic fire-fighting equipment.

The first vehicle goes to the La Rochelle fire brigade in France and has a compact bogie. Even with a 360 ° rotation, this does not protrude beyond the vehicle contour, which means that the turntable ladder can be positioned very close to a building or other obstacle. The L27A-XS 3.0 thus combines a multitude of functionalities and tactical advantages in one device. Together with the L27A-XS, Rosenbauer presents a new system for fall protection and height rescue.

Personal fall arrest device

All components come from a single source and are optimally matched to one another. It consists of up to 18 attachment points in accordance with EN 795, which are attached to the cage, to its underside, to the top of the ladder, to the articulation of the ladder set and to the bogie. The eyelets on the ladder set and on the bogie can also be retrofitted in older vehicles.

It also includes a personal fall arrest device, in which the seat belt retractor is on the man and not, as usual, on the anchor point. This has the advantage that the safety belt is not pulled over edges, but only lies over it when it is moved, because it is unwound directly on the person.

Complete modular package

The rope system (main rope and backup with rope brake) can of course also be used for height safety

In addition, there is a complete modular package available for rescue operations at heights, the individual components of which can be combined as required.

This includes, among other things, a manual cable winch (module winch) and a pulley block (module pulley) for support when rappelling up and down, a backup module for backing up the pulley system, the bridle module, consisting of a rescue triangle and lanyards to support a basket stretcher or to additionally secure a person inside, as well as the Static Line module (two bundled steel ropes with fixed lengths and carabiners) if the person is not to be rescued by abseiling but by moving the ladder set or the telescopic arm.

The rope system (main rope and backup with rope brake) can of course also be used for height safety, for example, when emergency services on a roof have to move further than two meters from the rescue cage. In addition, the system is designed in such a way that it can be used and applied correctly immediately and intuitively by any fire brigade who has been trained in ‘Simple rescue from heights and depths’.
