Manitowoc cranes vary widely in specifications depending on the model; typical parameters include:
- Operating Weight: From around 50,000 lbs for smaller models like the Igo M 14 to over 250,000 lbs for heavy-duty cranes such as the 3900 series.
- Maximum Lifting Capacity: Ranges from 10 tons in smaller mobile cranes to 300+ tons in lattice boom crawler cranes.
- Boom Length: Main boom assemblies commonly range from about 100 feet to over 200 feet, often expandable with jib attachments.
- Transport Dimensions: Designed for modularity, many models can be disassembled into transportable sections conforming to road regulations.
- Drive and Maneuverability: Equipped with powerful diesel engines paired with advanced hydraulic drives supporting smooth and precise machine movement even in rugged terrain.
- Versatility in Applications: Manitowoc cranes are used for high-rise construction, industrial plant assembly, bridge building, wind turbine erection, and port operations.
- Stability and Safety: Outriggers and counterweight systems are optimized to ensure safe lifts, with some models featuring variable positioning to adjust to site conditions.
- Advanced Controls: Modern Manitowoc cranes employ electronic load-moment indicators (LMI), anti-two-block systems, and remote monitoring to enhance operational safety and productivity.
- Transport Flexibility: Designed for field assembly and disassembly to navigate tight urban or remote sites effectively.
- Lattice Boom: A boom made of a crisscrossed metal framework, providing strength while minimizing weight.
- Crawler Crane: A crane mounted on a set of tracks (crawlers) allowing movement on rough terrain with stability.
- Counterweights: Heavy weights placed opposite the load to balance the crane during lifting.
- Variable Positioning Counterweights: Counterweights that can be adjusted in position to optimize balance and stability during operations.
- Jib: An extension attached to the boom to increase the crane’s reach and lifting height.
- Load-Moment Indicator (LMI): Electronic system that monitors load weight and boom angle to prevent overloads.
