RL250-12 Topless Hydraulic Luffing Jib Crane

RL250-12 Topless Hydraulic Luffing Jib Crane

The ZOOMLION RL250-12 high-rise tower crane offers greater lifting reach and faster hoisting for construction projects where space is at a premium. This topless hydraulic luffing jib tower crane is ready to handle material lifting at height, even on crowded urban jobsites. Its jib can rise to an angle of 87°, with an out-of-service parking radius as small as 15 m. Its compact arrangement gives contractors more flexibility on lifting coverage when working for high-rise construction around neighbouring buildings and other site restrictions.

  • Max. lifting capacity: 12 t
  • Max. jib length: 60 m
  • Jib tip load (60 m Jib): 2.4 t
  • Max. hoisting speed: 190 m/min

Features
  • Faster Installation and Easier Maintenance
    Major components like the jib root section with its luffing cylinder and the hydraulic pump unit with the counter-jib come pre-assembled for lifting and transport. Dismantling process is also easier as individual jib sections can be removed at height using auxiliary equipment without lowering the entire jib.
  • Greater Flexibility in Tight Spaces
    The jib can rise to an angle of 87° for lifting close to surrounding structures. An out-of-service parking radius of just 15 m and an ultra-short counter-jib make it easier to work around obstacles on crowded construction sites.
  • Enhanced Safety and Reliability
    The hydraulic luffing cylinder features a dual-locking mechanism and three layers of protection against internal oil leakage and hydraulic hose failure. The ETI digital control system provides real-time feedback and control for safer crane operation.
