Trailer cranes

The K280 is a reliable all-rounder for roofers and carpenters, most of whom work in the private construction sector. Its hook height is 25.5 m, the reach with a load of 250 kg is a proud 18.50 m. Since its buckling edge height is around 22 m, the K280 can also reach the rear sides of multi-storey residential buildings without having to move the crane. A hydraulic folding joint, which is operated by remote control, ensures comfortable and quick erection. Thanks to its self-propelled drive and a small footprint, the Klaas lightweight is the ideal crane for narrow construction sites.

K280 E – self-sufficient work without compromise

The K280 can be optionally equipped with an electric motor and a powerful battery. This allows the K280 E battery crane to be used not only in an environmentally friendly way, but also completely self-sufficiently. The energy storage can be charged at any standard 230-volt socket. Thanks to consumption-oriented settings and stop-and-go automatic, the crane can be operated for several days with a full battery charge.


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

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

Endlessly rotatable

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

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

Drive concept

  • equipped with an economic gasoline engine for the crane operation
  • low fuel consumption meaning enormous cost saving and reduction of environmental impact
  • electronic tank monitoring on the crane and via the remote control unit

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

Fly jib joint

  • hydraulic fly jib joint ensures quick and easy set-up
  • higher loads lifted on integrated extensions thanks to strong fly jib joint
  • dual fly jib cylinders for even more security and protection against lateral forces


  • after manual extension of the support cylinders, a hydraulic system ensures variable height levelling
  • ASC support monitoring system permanently checks the stability of the crane, also taking into account wind and ground conditions
  • l-shaped support ensure best possible safety against overturning
  • support without underpinning possible thanks to long, vertical cylinder

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

Self-drive mechanism

  • hydraulic self-drive mechanism operated by standard remote control
  • easy manoeuvring in tight spaces

Optional equipment

Battery-powered electric motor (K280 E)

  • charging of the energy storage via 230-volt socket
  • when fully charged, set-up and operation are possible for a complete working day
  • optimum utilisation of stored energy through automatic stop-and-go system

Accessory fix system

  • accessories are securely stored and immediately within reach
  • no cumbersome lashing necessary
  • custom-fit holders ensure safety on the road
  • crane equipped with fitting brackets
