The CCS features a full-color graphic display and dual-axis electronic joysticks that simplify the entire lifting process and is common with Manitowoc’s MLC range and Grove mobile hydraulic cranes. The 999’s EPIC system is replaced with the more user-friendly Manitowoc Crane Control System (CCS).
The crawler drive motor is relocated from the carbody to the tumbler to provide better performance. The crawler tracks are offered in standard 48-in shoe width and new optional 60-inch width for greater stability and reduced ground pressure. The upper platform is easily reached via new steps mounted onto the undercarriage.
The carbody counterweights now double as part of the upper deck and serve as a more stable walking platform, replacing the 999’s walkways that pivoted over the counterweights. With fewer pumps constantly requiring power, operators will see a more robust overall hydraulic performance, along with faster engine starting in cold weather. Now, every main function (aside from swing) is powered by the same two main pumps, reducing parasitic load. One key change is the switch to open-loop hydraulics, versus the closed-loop system on the 999. Key specifications largely remain unchanged, with the new MLC250 using the same #82 boom sections that provide a max boom length of 290 ft (88.4 meters) and class-leading load charts. Boom strength is affected the most when the wind acts on the side of the boom. “Fleet owners benefit from the extra flexibility and cost savings offered by this crane as it shares parts with many of Manitowoc’s legacy and current models.” speeds and load (see appropriate table for recommended capacity reductions). “The improvements are designed to make operators and service technicians work more efficiently - and in greater comfort,” Manitowoc said.
