Despite its low dead weight of 3.5 tonnes, the K21-30 RS is a powerful all-rounder. With its exceptionally strong boom, it can lift loads of up to 1,500 kg, and its lateral reach with a 250 kg load is an impressive 21 m. Thanks to its single-axle design, the trailer offers great maneuverability, optimal weight distribution, and increased ground clearance. The self-drive system allows for convenient maneuvering on the construction site. A retractable drawbar enables the total length to be reduced to 7 m, making it easy to set up the crane even in city centers.

Equipment

  • Extremely strong, weather-resistant, and very lightweight special aluminum alloy.
  • No loss of strength at the weld thanks to friction stir welding; the joints are as strong as the solid material.
  • The characteristic Klaas perforation reduces the wind-exposed surface area and weight while maintaining high resistance to deformation.

  • The fully hydraulic discharge system, combined with the ASC outrigger control, enables variable widths, including in the transverse direction.
  • Unlimited lateral extension.
  • L-shaped outriggers ensure maximum stability against tipping.
  • Long vertical cylinders allow for shoring without the need for struts.

  • the flange is machined from solid stock, enabling it to withstand higher loads
  • electronic pressure monitoring within the connection ensures optimal load-bearing capacity at any angular position
  • dual toggle cylinders provide enhanced safety and stability against lateral movement

  • torsion-free mast lifting thanks to these two lift cylinders
  • dual safety thanks to two cylinders
  • improved absorption of lateral forces, resulting in a stable and rigid mast position

  • rapid telescoping under load thanks to the patented Klaas cable technology
  • integrated electronic measurement records the mast extension length and calculates the maximum permissible load
  • the low weight of the cables increases reach and load capacity
  • easily accessible, low-maintenance cable technology

  • protected routing of all electrical and hydraulic cables integrated into the mast
  • no hose reels or cables on the mast
  • use of low-maintenance galvanized steel hydraulic hoses, preventing costly hose replacements

  • Complex control system compliant with EN 280 and EN 13000
  • State-of-the-art safety PLC for crane operation
  • CAN-bus control unit for highly sensitive and precise operation
  • Soft start/stop for low-impact operation
  • Expandable with an additional remote control

  • Large display for a clear view of all key crane operating states
  • Precise starting via proportional joysticks
  • Power supply via AA batteries or cable

  • powerful diesel engine for crane operation
  • low fuel consumption – resulting in huge savings and reduced environmental impact
  • electronic fuel level monitoring on the crane with remote control display

  • high-quality, German-made slewing ring
  • thanks to a well-engineered slewing bearing, the load can rotate continuously in both directions

  • Reduction of the total length from 9.25 m to 7.00 m, enabling installation in small spaces as well.

  • Self-propelled hydraulic drive with standard remote control
  • Easy maneuvering in tight spaces

  • The crane can be fully set up quickly and easily using the radio remote control.
  • Each individual outrigger can be extended laterally in a continuous motion.
  • Automatic leveling of the outrigger cylinders ensures optimal setup, even on uneven surfaces.
  • Constant pressure monitoring responds to changing external conditions.
