Trailer cranes

The K350 E is a trailer crane in the 3.5-tonne class with state-of-the-art equipment, high driving comfort and excellent performance values. Its maximum load is 1,600 kg, and its lateral reach with a load of 250 kg is an impressive 22 metres. Another plus point is its battery-powered electric motor, which allows it to be operated completely self-sufficiently and sustainably. A large lithium battery is used to store energy and can be charged at any conventional 230-volt socket. Charging can also be carried out while the crane is in operation, although this is not necessary due to a consumption-oriented setting and the strong battery power. The K350 E can easily be used for a whole working day without recharging.

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

Battery-powered electric motor (K350 E)

  • powerful lithium battery with 22 kWh enables self-sufficient crane operation for over 12 hours
  • charging of the energy storage via 230-volt socket
  • permanent charging also possible during crane operation

Self-drive mechanism

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

Hydraulic, telescopic fly jib

  • fly jib equipped with patented Klaas telescope technology
  • hydraulic telescoping of the first folding tip element via radio remote control
  • use of the folding tip even in tight assembly situations by "extending in the air
  • hydraulic telescoping also possible in stage operation

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

H-Outriggers

  • fully hydraulic support in conjunction with the ASC support monitoring system enables infinitely variable outrigger 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 possible thanks to long, vertical cylinder

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

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

Endlessly rotatable

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

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

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
  • equipment with memory function possible
  • this 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

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

Retractable drawbar

  • reducing the total length from 9.25 m to 7.00 m enables set-up even where there is not much room

Full panelling

  • roomy, lockable storage compartments
  • secure storage of tools and accessories
  • large storage surface on the crane
  • high-quality, neat overall appearance thanks to aluminium full checker plate panelling

Optional equipment

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.
