About Manitowoc MLC300 Crawler Crane
The Manitowoc MLC300 is a 300-tonne capacity model with a maximum load moment of 1,992 tonne-meters, increasing to 4,119 tonne-meters with the optional VPC-Max capacity enhancement system. The maximum boom length is 96 m, and the maximum luffing jib length is 96 m. The maximum boom and jib combination length is 144 m.
The MLC300 is designed to be easily transported anywhere in the world with its optimized component weights and dimensions. It has a removable live mast shipping module, and its boom inserts are designed to allow luffing jib inserts to ship within them, which reduces shipping costs. It also uses Manitowoc's patented FACT connection technology and is operated via Manitowoc's Crane Control System (CCS), a standard operating system across several crane models in different product ranges.
This 330 USt crawler crane made its debut at CONEXPO 2014 in March and features the groundbreaking Variable Position Counterweight (VPC) technology. and has since gained acceptance from many users.
Revolutionary VPC™ Technology
The MLC300's standout feature is Manitowoc's proprietary Variable Position Counterweight™ system. Unlike conventional cranes that rely on a fixed passive counterweight, the VPC™ system automatically positions the upperworks counterweight along the rotating bed based on:
Lifted load
Boom length
Load radius
This real-time adjustment optimizes crane stability and lifting capacity while eliminating the need for carbody counterweight. The result? Better center of gravity distribution, reduced ground bearing pressure, and simplified transport.
About the undercarriage of the MLC300 Crawler Crane
Connects rotating bed and crawler frames. Each frame is mounted to the carbody with the FACT connection system and hydraulic power-actuated pins. Crawler assemblies are 32 ft long with 48 in wide cast steel crawler pads and automatically lubricated intermediate rollers. Left and right side crawlers are interchangeable to provide assembly/disassembly flexibility on jobsites. Each crawler is powered independently by a variable displacement hydraulic motor connected via screw together hydraulic quick disconnects. Crawlers provide ample tractive effort for travel and counterrotating with full rated load. Maximum ground speed of .8 mph. Optional: 60 in wide treads.
Now we can supply the 48 in wide track shoes for the MLC300 crawler crane.
Except these track treads, we can also supply parts for other Manitowoc crawler cranes, such as Manitowoc 2250, 16000, 4100, 222, 10000, 888, 3900, etc., so, for more details, please contact us freely.
