Mobile cranes

The K2500 is the new “big one” from Klaas with record-breaking performance values. Thanks to an innovative mast system with triple hydraulically telescoping folding jib and a small footprint of max. 7 m width, the K2500 is the ideal crane for city centres with limited space. The all-rounder is also predestined for covering huge roof areas thanks to its lateral outreach of 45 m with a 500 kg load. The K2500 is particularly impressive with its enormous outreach values in combination with large hook heights in the load range up to three tonnes. The new Klaas top model also achieves impressive heights and reaches as an aerial work platform.


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

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

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

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

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

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

XL Radio remote control

  • precise starting thanks to sensitive joysticks
  • memory function 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
  • second display ensures all the crane’s key operating statuses are clearly displayed, such as angle of inclination and rotation, max. lifting capacity, hoisting cable speed
  • power supplied by standard batteries or cable

Hybrid drive

  • equipped with 400 volt electric motor and separate Diesel engine
  • quiet operation without polluting exhaust gases with electric motor
  • use of the separate diesel engine on construction sites without power access

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

Personal safety mode

  • personal safety mode in accordance with BG guidelines
  • for working at great heights without stationary securing options such as scaffolding or safety eyes
  • securing of persons by crane boom allows free working at exposed places

Endlessly rotatable

  • high-quality turntable from German brand manufacture
  • well thought-out rotary guide enables endless rotation of the upper carriage in both directions

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


  • 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
  • horizontal outriggers are double telescopic and offer optimal stability due to the large overlap
