Manitowoc MLC165-1

The Manitowoc MLC165 was introduced at Bauma 2013 in Germany, showcasing enhanced transportability, ease of setup, and improved performance in the 165-ton class. Designed as a replacement for the successful Manitowoc 777 and 555 crawler cranes, the MLC165 comes equipped with high-strength structural components and modular systems that simplify assembly and reduce mobilization time.

The crane’s main boom is 84 meters in length, constructed using No. 74 tubular chord boom sections. When paired with the No. 134 fixed jib, it can achieve a boom-and-jib combination of 93.4 meters (69 m + 24.4 m). For heavier and more demanding applications, it can be configured with a luffing jib (No. 135), reaching a total length of 102.8 meters (51 m + 51.8 m). These configurations provide versatile options for varying job site needs.

Powering the crane is a choice between two 6-cylinder Cummins diesel engines — the QSL9-300 Tier III rated at 300 hp and the QSL9-320 Tier IVi rated at 320 hp. Both options offer reliability and fuel efficiency, with provisions for cold-weather starting and emissions control systems. The hydraulic system is driven by three high-pressure pumps, offering simultaneous multi-function operation with closed-loop swing control and a fourth pump for free fall.

The counterweight system includes both upper and carbody weights, totaling up to 156,750 lbs (71,085 kg), improving stability across various configurations. The operator’s cab is fully enclosed, air-conditioned, and equipped with large safety glass windows for excellent visibility. Optional features include a tilt cab and nylon window covers for added operator comfort and safety.

Its swing system allows 360-degree rotation with a 2.5 rpm maximum swing speed, while the wide crawler assemblies ensure solid traction even on challenging terrain. The crane also supports Manitowoc’s FACT™ system, which simplifies crawler removal and installation, further enhancing job site efficiency.

The MLC165 also comes standard with Manitowoc’s CANBUS control system and Rated Capacity Limiter (RCL), offering precise control, diagnostics, and safety monitoring. Optional self-erect systems and block configurations up to 165 USt further expand its operational flexibility.

This crane is ideal for heavy lifting in confined job sites and is well-suited for industrial construction, infrastructure, and petrochemical applications — as proven in its deployment for Mexico’s Ethylene XXI project by Gruas Villarreal, the first unit sold in Mexico.
