VPC® (Variable Position Counterweight)
The VPC® system automatically positions the counterweight to fit the required lift.
The VPC® system automatically positions the counterweight to fit the required lift. The counterweight moves along the rotating bed and is automatically positioned based on changes in boom angle.
The VPC-MAX® attachment for the MLC650 raises the crane’s capacity to 700 t (770 USt) an increase of 50 t (55 USt) over its standard configuration. The attachment provides capacities similar to wagon- or tray-mounted attachments but requires significantly fewer components and assembly steps reducing setup time and transportation costs.
The VPC is game-changing technology
VPC® advantages for customers
Advantages for customers include reduced ground preparation lower ground-bearing pressure and less counterweight without sacrificing capacity. Customers will not have to buy transport or install as much counterweight compared with a traditional configuration. The counterweight boxes are also designed to be common across multiple crane platforms.

MLC300 VPC-MAX
Manitowoc’s new Model MLC300 utilizes Variable Position Counterweight®(VPC®) proprietary technology to “actively” engage all counterweight and eliminate the need for “passive” carbody weights. The design results in a dramatically reduced transport configuration and better center of gravity for reduced ground bearing pressures. The Model MLC300 is available in VPC® and VPC-MAX® configurations for additional capacity.

MLC650 VPC-MAX
The new Manitowoc MLC650 features a Variable Position Counterweight® (VPC®) that allows the crane’s counterweight to be positioned automatically while still offering an unmatched level of versatility and capability. In addition to the VPC® the optional VPC-MAX® attachments increase the capacity boom and jib combination lengths while utilizing all of the standard VPC® components. The Crane Control System is also a newly-added feature that aids the operator in a quick and easy set-up.
