Kobelco SL4500

​The Kobelco SL4500 is a crawler crane with a maximum lifting capacity of 400 metric tons (440 U.S. tons). Its boom has a maximum length of 96m (315 ft.), and a maximum luffing jib combination that is: 78m (256 ft.) + 66m (217 ft.). It has 3 different operating modes, standard, heavy lift and super heavy lift. The booms and jib attachments consist of welded lattice construction using tubular, high-tensile steel chords with pin connections between sections. The boom hoisting system is powered by a hydraulic motor through a planetary reducer, and comes standard with boom backstops. The SL4500G Optional inserts and extensions are available as well.

The SL4500 is equipped with a Hino diesel engine E13C-UV that produces 429 HP and comes with a 158 gal fuel tank. The hydraulic system uses a full-flow hydraulic control system for infinitely variable pressure to all winches, propel and swing. Controls respond instantly to the touch, delivering smooth function operation. Kobelco crawler assemblies are also designed with quick disconnect feature for individual removal as a unit from axles. The crawler belt tension is maintained by hydraulic jack force on the track-adjusting bearing block.

The upper structure of the crawler is a torsion-free precision machined upper frame. All components are located clearly and service friendly. The cab is totally enclosed and has full vision with safety glass. There are five adjustable levers for all winches and swing controls. The swing unit of the crane is powered by a hydraulic motor driving spur gears through planetary reducers, and provides 360° rotation.

For specific lengths and lifting capacity of the booms and jibs while in different operating modes, please reference the crane chart. To find out more about the Kobelco SL4500, please contact us.
