Sumitomo SC400

Sumitomo’s SC400 crawler crane is a robust lifting machine engineered for medium-scale construction projects. It comes with a powerful Mitsubishi 6DCT Turbo Intercooler engine, producing 150 horsepower at 2100 rpm, and a gradeability of 40%, allowing it to navigate steep inclines with ease.

The crane offers a significant maximum lifting capacity of 40 tons at a 3.7-meter radius and can reach up to a 49-meter height with its main boom. For tasks requiring extended reach, the jib extends from 6.10 meters to 15.25 meters, with the combined length of the boom and jib topping at over 55 meters.

A notable feature of the SC400 is its substantial load moment, capable of handling a maximum load at a 46-meter radius, underpinned by a robust and stable design, with a total machine weight of 40.9 tons including base counterweights. Despite its weight, the ground pressure exerted is a modest 0.57kg/cm² when equipped with 760mm wide shoes, minimizing impact on the work site.

The crawler crane also offers a slewing speed of 3.4 revolutions per minute and variable travel speeds for operational efficiency. With such features, the Sumitomo SC400 is tailored for a range of construction environments, from bridge building to steel structure erection, offering reliability and performance in its class.
