While the SK550DLC-11 is a common base machine, the Next system attachments means that the machine can be adapted for multiple applications on the jobsite. The machine has four ultra-long attachment configurations and can work to a maximum height of 27.5m. The separate boom configuration is suited for tackling lower floors of tall buildings and has a maximum working depth of 6.2m. The reinforced attachments can be changed on site. An important benefit of the Next system is the low storage height of the ultra-high attachment when collapsed. The height of the attachment in its stored position is approximately 2m, which means that it can be transported between projects on a standard trailer. Other factors contributing to transportation include a hydraulic extension/retraction mechanism, which can reduce the width of the crawlers to 2.98m in compliance with some European transport regulations, and the two-part counterweight, which can be separated more easily than an integrated counterweight, according to Kobelco.

The SK550DLC-11 also benefits from the use of an electronically controlled environmental engine, which is compliant with the European Stage V emission regulations. Engine output is 10% or more higher than the previous model, according to Kobelco. The Auto Idle Stop function enhances efficiency by avoiding unnecessary fuel consumption. Like Kobelco’s conventional Generation 11 excavators, the SK550DLC-11 follows Kobelco’s Performance X Design concept for operator-based operability and wellbeing. The Kobelco-branded Grammer air suspended seat offers shock absorption. It also includes a wide four-inch arm rest that allows the operator to take a comfortable position, and a seat heater. The cabin’s large 10-inch colour monitor offers a menu screen which facilitates reading of important information. The screen also provides birds-eye and eagle-eye views from the machine’s cameras. The demolition-specification cabin is fitted with security glass and radial grid guards across the front and top windows and can tilt up to 30-degrees. If the attachment comes within a certain distance of the cab, an alarm and warning on the screen alert the operator, and the attachment stops. The working radius and stability of the machine are calculated from the position of the attachment, and the operator is warned with an alarm when stability is compromised. The reversible cooling fan helps to keep the machine’s cooling system clean by blowing out dust automatically. The urea lines, which are electrically heated, help to avoid issues at low ambient temperatures.
