The 670SJ Self-Leveling Boom allows the boom lift to traverse uneven ground up to 10-degrees while keeping the chassis level. This results in decreased platform movement during travel and full functionality while driving at height. 

  • Increases a lift's capability on slopes 0° to 10° in any direction with the boom elevated
  • Improved ability to traverse uneven surfaces while keeping the chassis level and improve traction capability on sloped ground
  • Jlg Self Leveling Technology 167-ft. platform height boom lift with 550-lb. unrestricted, 750-lb. restricted capacity
  • Offers 45% gradeability
  • 57-ft. 1-in. horizontal reach
  • Elevates to full height or back to ground level from full height in just 101 seconds
  • Automatically levels on grades up to 10° when in self-leveling mode
  • Standard mode enables driving with the boom down at faster speeds; shipping mode allows the suspension to be lowered during transport
  • Smart suspension results in a foot more platform height
  • Reduces or eliminates manual labor and time required to set up cribbing and/or grade the work area
  • Allows lift to get closer to the work area, maximizing its reach capabilities and minimizing the need for larger,  higher reaching backup lifts 
  • Decreases platform movement during travel improving operator comfort and reducing the risk associated with movement of objects within and/or falling from the platform

The seed idea for the self-leveling boom lift came as the result of identifying and understanding customer needs. After seeing how challenging select boom lift applications could be, JLG engineers realized that the industry as a whole had designed current lifts for the near ideal conditions of firm, flat surfaces with a grade of 5° or less. This was the root cause of many customer pain points, because the world is neither flat, nor does it come with improved surfaces.
