Manitowoc M-250 Series 3

The Manitowoc M-250 Series 3 crawler crane delivers a maximum rated lifting capacity of 250 US tons (226.8 metric tons). It is built for critical and high-reach heavy lifts, and is designed around a 360-degree lifting platform. With an engineered main boom reaching up to 300 feet, and jib extensions up to 120 feet when paired with a 250 ft boom, the M-250 provides remarkable vertical and horizontal reach.

The crane includes 30’9″ wide crawler tracks and 48″ treads, which offer stability on uneven ground and reduce ground bearing pressure. It features a 28-foot retractable gantry, 12-part hoist reeving, and 1.5-inch wire rope, which accommodates high-capacity lifting with minimal flex. The lifting configuration includes four 1.5-inch boom pendants or boom support straps, maximizing boom stability under load.

To maintain balance and enhance lifting performance, the M-250 employs a comprehensive counterweight system consisting of:

• 248,700 lbs of crane counterweight
• Two 30,000 lb units
• Four 15,000 lb carbody counterweights

The M-250’s upper boom point capacity supports 30,000 lbs with a single whip line, or 60,000 lbs with a two-part whip line, but only when not using a jib. In configurations where jibs are attached (using Jib No. 132), the boom point cannot be used, and lifting capacity deductions apply—for example:

• 40 ft jib: subtract 6,400 lbs
• 80 ft jib: subtract 10,300 lbs
• 120 ft jib: subtract 15,300 lbs

The machine is compliant with ANSI B30.5 requirements, and its rated capacities do not exceed 75% of tipping load for freely suspended loads. Lifting capacities vary based on boom length, radius, and rigging, and are strictly limited to structural or stability constraints.

The M-250’s structure and rated performance are best suited for large-scale infrastructure work, such as bridges, petrochemical facilities, offshore modules, and power plant construction. With its long reach, stable lifting geometry, and heavy-duty crawler base, the Manitowoc M-250 remains a trusted machine for high-capacity crawler operations.
