Kobelco SL4500G

​The Kobelco SL4500G crawler crane has a maximum lifting capacity of 400 metric tons (440 U.S. tons), a maximum boom length of 96m (315 ft.), and a maximum luffing jib combination that is: 78m (256 ft.) + 77m (255 ft.). It has three lift 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. Optional inserts and extensions are available as well.

The SL4500G is equipped with a Hino diesel engine E13C-VV that produces 442hp 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 which provides smooth operation of the crane. There are five adjustable levers for all winches and swing controls. Different pump systems are used for different parts of the crane. The swing unit is powered by a hydraulic motor driving spur gears through planetary reducers (4 sets), and provides 360° rotation

Also, the swing parking brakes has a spring-set, which uses a hydraulically released multiple-disc brake that is mounted on the swing motor. Kobelco crawler assemblies are designed with quick disconnect feature for individual removal as a unit from axles making it easier to assemble and disassemble. The steering mechanism uses a hydraulic propel system which provides both skid steering and counter-rotating steering, allowing it to move up to 20% grade terrain.

The cab is totally enclosed and has full vision with safety glass. The upper structure of the crawler is comprised of a torsion-free precision machined upper frame. All components are located clearly and service friendly.

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 SL4500G, please contact us.
