Trailer cranes

K23-33 TSR City

With a hook height of nearly 33 m, the K23-33 TSR City is the largest trailer crane produced by Klaas. With its lateral range of 23 m with a load of 250 kg, it features an enormous radius of action. The aluminium crane can be converted into a work platform in a few minutes without tools, thus enabling varied, safe work on the building site. Thanks to its self-drive mechanism it is able to manoeuvre into suitable gap with pinpoint accuracy and be shortened to 7 m due to its retractable drawbar. As a single axle model with a low net weight of 3.5 t, it is also easy to handle in tight spaces.

Equipment

Mast 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
Automatic set-up
  • 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-support
  • 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 possible thanks to long, vertical cylinder
Fly jib joint
  • higher loads lifted on integrated extensions thanks to newly designed fly jib joint
  • pressure monitoring in the fly jib cylinders guarantees optimal lifting of loads in any angular position
  • dual fly jib cylinders for even more security and protection against lateral forces
Dual luffing 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
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

einschiebbare Deichsel

  • reducing the total length from 9.25 m to 7.00 m enables set-up even where there is not much room
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)
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
  • all the crane’s key operating statuses shown on the display
  • power supplied by standard batteries or cable
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

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
  • upper structure with the boom can be rotated 360°

Optional equipment

Self-drive mechanism
  • hydraulic self-drive mechanism operated by standard remote control
  • two-axle models equipped with a lift axle
  • easy manoeuvring in tight spaces

Elevating work platform

  • crane quickly converted into a fully fledged elevating work platform without tools
  • 230 V socket for drill etc. directly in the work platform
  • platform can be swivelled to each side by 45°

Accessory fix system

  • accessories are securely stored and immediately ready to hand
  • no cumbersome lashing necessary
  • custom-fit holders ensure safety on the road
  • crane equipped with required holders

Mounting-/glass hook

  • assembly hook enables precise material transport
  • application area: e. g. glass mounting with vacuum lifter
