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 26.0 m, the reach with a load of 250 kg is a proud 19.00 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.


Equipment

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

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

Doppelte Wippzylinder

  • verwindungsarmes Anheben des Auslegers dank zweier Wippzylinder
  • doppelte Sicherheit durch zwei Zylinder
  • bessere Aufnahme seitlicher Führungskräfte, dadurch stabiler und ruhiger Stand des Auslegers

H-Outriggers

  • 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

Drive concept

  • powerful diesel engine for the crane operation
  • low fuel consumption meaning enormous cost saving and reduction of environmental impact
  • electronic tank monitoring on the crane and display via the remote control unit

Teleskopierwinde

  • zügiges Teleskopieren unter Last dank patentierter Klaas Seiltechnik
  • integrierte elektronische Längenmessung erfasst aktuelle Ausfahrlänge des Mastes und berechnet maximal mögliche Traglast
  • geringes Eigengewicht der Seile erhöht Ausladung und Tragkraft
  • wartungsarme und sehr gut zugängliche Seiltechnik

Kransteuerung

  • komplexes Steuerungssystem nach EN 280 und EN 13000
  • hochmoderne Sicherheits-SPS für den Kranbetrieb
  • CAN-BUS Steuerblock für besonders feinfühliges und genaues Arbeiten
  • sanfter Start-Stopp für schwingungsarmes Arbeiten
  • Erweiterung um zusätzliche Fernsteuerung möglich

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

Endlos drehbar

  • hochwertiger Drehkranz aus deutscher Markenfabrikation
  • durchdachte Drehführung ermöglicht endlose Drehbarkeit des Oberwagens in beide Richtungen

Self-drive mechanism

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

Optional equipment

Battery-powered electric motor

  • high-capacity battery combined with energy-efficient crane settings for extended operating times
  • efficient energy use thanks to automatic stop-and-go functionality
  • can be charged via a 230-volt socket
  • The battery can be charged even whilst the crane is in operation.

Zubehör-Fix-System

  • Zubehör ist sicher verstaut und sofort griffbereit
  • kein lästiges Verzurren notwendig
  • passgenaue Halterungen gewährleisten Sicherheit im Straßenverkehr
  • Ausstattung des Krans mit gewünschten Halterungen
