Tiny Engine, Tall Reach: New Skyjack SJ9664 RT Lift Reaches a Steep 7 Stories

The new Skyjack SJ9664 RT is a 70-foot working height rough-terrain model with the ability to reach seven stories.

“We looked at products that were offered within a traditional range and products that are more specialized with higher platform heights but with much higher acquisition costs,” says Corey Connolly, Skyjack product manager. “We aim to find a middle ground with the SJ9664 RT.”

The model has an axle-based four-wheel drive system, Smartorque technology and an expansive workspace, says Skyjack, a division of Linamar.

Using Smartorque, Skyjack says it was able to power the SJ9664 RT with a smaller Kubota engine while delivering the same performance of higher horsepower units. By adjusting axle gear ratios and maximizing hydraulic output, the scissor provides additional performance with less engine horsepower, says Skyjack.

With a 6-foot-wide by 14.5-foot-long work platform, the unit has an option of single or dual 5-foot extension decks, providing a large working space for personnel, tools and material.

The SJ9664 RT has a commonality of parts shared with Skyjack’s other full-size RT scissors. The unit also features an impact-resistant control box, increased leveling capability and better protected components, says the company. 

Other key features include:

  • A reinforced scissor stack that promotes increased rigidity
  • Simplified e-lowering
  • Onboard diagnostic display
  • Self-centering scissor design, which supports the optional dual extension decks
  • Compatible with the company’s Accessoryzers line of accessories, including a pipe rack and material handling stand

The SJ9664 RT is supported by the optional Elevate telematics solution, which allows operators to see engine faults and other machine health metrics through a QR code system.
