Firefighting technology

Whether it is used for firefighting or on builder’s yards, this Klaas multifunctional appliance is impressive all round. The ways that the AluFiver can be used are as varied as the cases dealt with every day by the fire brigade and technical support services. It is designed so that firefighters can work quickly and efficiently with the appliance even under extreme conditions. The automatic set-up and dismounting system enables a simple and safe procedure especially in precarious situations. Its compact dimensions make even places that are difficult to reach accessible.


Telescopic winch

  • quick telescoping under load thanks to patented Klaas rope technology
  • integrated electronic length measurement records current extension length of the mast and calculates maximum possible payload
  • low net weight of the ropes increases range of action and payload
  • low-maintenance and very easy to reach rope technology

Energy supply

  • protected routing of all moving electrical and hydraulic leads in or on the mast
  • no hose or cable reels on the mast
  • low-maintenance hydraulic pipework made of galvanised steel used in the substructure, meaning there is no need to change hydraulic hoses

Double derricking cylinders

  • boom raised with low torsion thanks to two luffing cylinders
  • double safety due to two cylinders
  • better absorption of lateral guide forces, making the boom more stable and still

Drive concept

  • separate powerful diesel engine for the crane operation
  • low fuel consumption meaning enormous cost saving and reduction of environmental impact
  • the truck engine is not put under strain by the crane operation
  • electronic tank monitoring on the crane and display via the remote control unit

Twin luffing cylinders

  • folding jib joint is milled "from the solid" and thus enables higher load bearing capacity
  • electronic monitoring in the joint guarantees optimal lifting of loads in any angular position
  • twin luffing cylinders for even more security and protection against lateral forces

Radio remote control

  • precise starting thanks to sensitive joysticks
  • large display provides a clear indication of all the crane’s key operating statuses
  • power supplied by standard batteries or cable
  • equipment with memory function possible
  • this learns two target points (e.g. where material is on the ground and unloading point on the roof), during which the crane moves in safe hold-to-run mode

Automatic levelling

  • the crane is completely set up quickly and easily using the radio remote control
  • each individual support infinitely extends laterally
  • automatic levelling of the support cylinders for optimal set-up even on uneven surfaces
  • constant pressure monitoring reacts to changing outside conditions

Boom system

  • extremely strong and weather-resistant aluminium special alloy with low net weight
  • no strength loss in the welding seam due to stir welding process, joints are as strong as the solid material
  • typical Klaas hole pattern ensures smaller wind-exposed areas, low net weight and high dent resistance

Crane control system

  • complex control system according to EN 280 and EN 13000
  • ultra-modern safety PLC for the crane operation
  • CAN BUS control block for particularly sensitive and accurate work
  • soft start/stop for low-vibration work
  • extension with additional remote control possible

Full panelling

  • spacious, lockable storage compartments
  • safe storage of tools and accessories
  • large storage space on the crane
  • the aluminium chequer plate design gives the crane a high-quality and clean look


  • fully hydraulic support in conjunction with the ASC support monitoring system enables infinitely variable support widths, also in the direction of the range of action
  • no fixed increments that restrict the operator
  • l-shaped support ensure best possible safety against overturning
  • support without underpinning thanks to long, vertical cylinder

Five good reasons

1. Elevating rescue platform

The three-person aluminium basket retains its balance at all times and can be pivoted horizontally in both directions by 25°. Even with a fully loaded basket of 300 kg, the elevating rescue platform reaches a height of 30 m and an 18 m range of action. The automatic set-up and dismounting system enables a simple and safe procedure especially in stressful situations. The basket is equipped with several 24 V LED headlights, meaning that work can be performed safely from the basket even under adverse lighting conditions. Using the dual controls, the platform can be operated both at a distance of up to 100 m and from the platform itself. The possible basket load capacity is permanently queried and shown on the display.

2. Extinguishing arm

The water supply integrated in the telescopic boom and the ability to control the monitor using the remote control unit make it possible to extinguish fires from great heights. The extinguishing monitor can be precisely operated with the remote control without having to take persons up in the basket. The monitor is also designed for tackling fires with foam, with other connection options provided.

3. Crane function

The crane function of the AluFiver is based on the easy operability of a mobile crane and has been specially adapted for firefighting and use in builder’s yards. The high strength, lightweight aluminium mast allows great heights and ranges even with medium-heavy loads. The remote control unit’s display can be used to constantly retrieve all the essential information, such as the load picked up.

4. Light tower

Six xenon headlights (230 V) integrated in the work platform, which can be vertically directed using the remote control unit, illuminate the deployment sites perfectly – there is no need to spend time laying cables. Additional 230 V (AC) or 24 V (DC) light sources can be installed if required.

5. Power supply station

The basket is supplied with power coming from a 230 V generator in the upper structure via the tower. The elevating rescue platform is equipped with two shockproof sockets, meaning that electrical appliances can be connected without any problem. Furthermore, voice communication to the upper structure helps procedures to run smoothly.
