Manitowoc Heavy Lifters

摘要

New from Manitowoc are the 330-ton MLC300 and 716-ton MLC650 crawler cranes featuring the company's Variable Position Counterweight (VPC) system. The VPC system automatically positions the counterweight to accommodate the required lift, moving the counterweight along the rotating bed and positioning it based on changes in boom angle. According to Manitowoc, benefits include reduced ground preparation, lower ground-bearing pressure, and less counterweight (to buy, transport, and install)-all without sacrificing capacity.
