There are several design differences between the SL and ISL Models, but one of the main differences in our SL Model is the absence of a traversing hook. We intentionally designed the SL Model without the ability to traverse a load in order to add stability to a narrower structural frame. Quite simply, because the SL cannot traverse, we are able to design it to fit into a tighter space all while maintaining consistent load stability.
The SL Model has all the benefits that come with our 50 years of engineering expertise, but without the additional options available on the ISL. An SL Model from Shuttlelift will perform almost any task that an ISL will, but will do so more slowly (longer cycle times), with less maneuverability (due to the non-traverse capability).
The SL Models from Shuttlelift are engineered to lift from fifteen to five hundred tons. Our main frame is high strength, low alloy steel with box section design. We bend our plate steel and fasten it together using two welds instead of the four box welds that most companies use. The Pivot Trunnion joint in our cranes permits side frames to oscillate, neutralizing frame stress under load on uneven terrain. The SL’s hydraulic system is simple with a single gear pump containing four mains and one auxiliary section driven off the engine flywheel.
