HYDRAULIC TRACTOR CRANE 

HYDRAULIC TRACTOR CRANE DOT 50ZK

  • Off-road tractor crane with self-contained hydraulic system
  • Oil reservoir, integrated into the base
  • With a link drive and three-point coupling of category II or III
  • The possibility of fixed mounting to a forestry trailer
  • Two stage telescope with integrated hydraulic hoses in cranes arm
  • Patented ZK mechanism
  • 29´of reach
  • Option: oil cooler
  • Brake BR1/80/4
  • More control opitions: 
    • electro-proportional control (only guide),
    • mechanical control,
    • mechanical control with 2 electric ON-OFF valves,
    • electro-proportional control with 2 joysticks,
    • Scanreco radio remote control.

A special version of the two stage telescoping arm for increased reach.

  • Patented ZK mechanism on the restraint between the lifting and the swinging arm provides for excellent work characteristics of the crane.

  • Hydraulic pump

    Based on hydraulic crane mounting we can choose between two hydraulic pumps couplings. The pump with female coupling enables three point hitch tractor mounting. The pump with male coupling enables fixed forestry trailer mounting. Both pumps come with 119 ccm displacement (recommended RPM of PTO 750 min-1 or 1000 min-1).

  • Pressure and return filter for ensuring the required purity of oil in the hydraulic system.

  • Robust stabilizer legs ensure a stable setting even on an uneven work terrain.

  • Stabilizer cylinders with integrated brake valves.

  • Lifting cylinder protection.

  • Excellent kinematics of the crankshaft mechanism.
