Manitowoc 4100W Series 2

Introduced in the late 1970s, the Manitowoc 4100W Series 2 is an evolution of the original 4100W model, incorporating enhancements in lifting capacity, boom configurations, and operational efficiency. This crane has become a staple in heavy-duty lifting operations across various sectors, including infrastructure development, industrial construction, and marine projects.

At its core, the 4100W Series 2 boasts a maximum lifting capacity of 230 tons (208 metric tons). The crane’s main boom, designated as Boom No. 22C with an open throat top, can extend up to 220 feet (67 meters), providing substantial reach for diverse lifting scenarios. For additional versatility, it can be outfitted with a 40-foot (12-meter) fixed jib, allowing for extended reach and improved load placement in complex job sites .

The crane is powered by a robust Cummins NTA-855-C360 diesel engine, delivering reliable performance and ensuring efficient operation under heavy loads. Optional engine configurations include the Caterpillar D-343TA, Caterpillar 3406 PCTA, and GM 12V-71N, offering flexibility based on operational requirements .

Stability and balance are critical in heavy lifting, and the 4100W Series 2 addresses this with a comprehensive counterweight system. It includes a 146,400-pound (66,400 kg) crane counterweight and a 60,000-pound (27,200 kg) carbody counterweight, ensuring optimal stability during operations .

The crane’s undercarriage features 26’6″ (8.08 meters) extendable crawlers with 48-inch (1.22 meters) treads, providing a stable base and excellent maneuverability on various terrains. The 17-foot (5.18 meters) retractable gantry and 12-part boom hoist reeving system facilitate efficient boom assembly and disassembly, enhancing operational efficiency .

Operational safety and precision are paramount, and the 4100W Series 2 is equipped with features such as an automatic boom stop, which utilizes a push rod to contact the boom actuating valve, automatically halting the air supply to the independent boom hoist hydraulic pump positioner .

In summary, the Manitowoc 4100W Series 2 combines robust lifting capabilities, versatile configurations, and reliable performance, making it a preferred choice for heavy lifting tasks in various industrial applications. Its enduring design and adaptability continue to meet the demands of modern construction and industrial projects.
