Mobile cranes

The K900 RSX – set up on a 13.5 t truck – is impressive due to its hook height of over 38 m as well as due to its enormous strength. With a maximum load capacity of 5,000 kg, it can even reach work areas 6.50 m away and 8.20 m high. Equipped with a double hydraulic telescopic fly jib, the crane can also be set up where there is not much room – also when operating as a work platform. Thanks to its modern radio remote control with integrated memory function, it is able to recognise two target points and moves between these automatically and in a safe hold-to-run handling mode.

Equipment

Telescoping 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

Dual 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

  • higher loads lifted on integrated extensions thanks to newly designed folding jib joint
  • pressure monitoring in the folding jib cylinders guarantees optimal lifting of loads in any angular position
  • twin luffing cylinders for even more security and protection against lateral forces

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 new 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

V-Outriggers

  • 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

Crane control system

  • 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
  • radio remote control with LCD display (can also be operated with cable, e.g. in case of wireless network interference)

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

XL Radio remote control

  • 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
  • difficult-to-see places moved to with pinpoint accuracy
  • 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

Hydraulic, telescopic fly jib

  • hydraulic telescoping of the first and second folding top elements
  • simultaneous extension of both drawers ensures optimum load distribution
  • utilization of the folding tip even in narrow body situations thanks to variability and "extending in the air"
  • hydraulic telescoping also in stage operation

Endlessly rotatable

  • upper structure with the boom can be rotated 360°

Personal safety mode according to BG guidelines

  • models are prepared for 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

Optional equipment

Hybrid drive

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

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

Working platform

  • The crane can be converted to a fully-fledged working platform in less than 5 minutes.
  • 230 V socket provides power for electric tools in the working platform.
  • The working platform can be swivelled left and right by 45° to either side.

Mounting-/glass hook

  • every Klaas mobile crane can be equipped with an optional mountinghook function
  • assembly hook enables precise material transport
  • application area: e. g. glass mounting with vacuum lifter
