Mobile cranes

The new K2350 with a hook height of 51 m combines the enormous power of the K2300 with the innovative, triple hydraulically telescopic folding jib of the K2500.

Thanks to its solid aluminium rails and a particularly strong folding jib, this powerhouse can transport materials weighing up to 2,000 kg an impressive 26 m. Even with a hook load of three tonnes, it still achieves a lateral reach of 19 m. In single-rope operation, the powerful hoist can lift loads of up to 4,500 kg.

On request, the K2350 is available with a newly developed two-strand operation. This allows it to effortlessly lift up to 9 tonnes to a height of 18 m. Particularly practical: the change from single to double strand operation is automatic, tool-free and simply at the touch of a button on the remote control. As the second crane hook is already integrated into the mast, no additional assembly is required.

Solid support cylinders, double telescopic horizontal support beams and a maximum support width of only 7.34 m make the K2350 the perfect partner even in narrow city centres.


Equipment

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

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

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

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

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

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

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

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
  • high-quality and clean overall appearance thanks to powder-coated smooth aluminium sheet
  • Spacious storage compartments with lockable latches offer plenty of space for crane equipment and tools.

Double hydraulic, telescopic fly jib

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

Optional equipment

Two-string operation
  • tool-free changeover from single to two-string operation
  • automatic crane positioning for two-string operation via remote control
  • integration of a second crane hook in the mast eliminates the need for additional installation

Battery-powered electric motor

  • silent and flexible thanks to modern battery technology
  • energy-efficient crane control and large 70 kWh battery system for long operating times
  • charging of the energy storage system via 230-volt socket, high-voltage current or via a wallbox for electric cars
  • working platform operation via battery possible

Mounting-/glass hook

  • assembly hook enables precise material transport
  • application area: e. g. glass mounting with vacuum lifter
  • flexibility in length and tilt angle facilitates difficult installations

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.
  • with 230 V socket and standardised lashing points for securing persons
  • The working platform can be swivelled left and right by 45° to either side.
