Variable Position Counterweight™ (VPC™): The Manitowoc MLC300 features a counterweight system which automatically positions the crane’s counterweight as required to match lifting demands. Crane lifting capability is optimized by automatic positioning of the counterweight, eliminating the need for carbody counterweight. Additionally, counterweight boxes are designed to be common across multiple crane platforms and are utilized on Manitowoc Model MLC650 as well as future models.

VPC-MAX™: Capacity and boom and jib combination lengths can be increased through addition of the exclusive VPCMAX™ attachment. The VPC-MAX™ attachment, configured with 98.4 ft fixed mast counterweight beam and standard VPC™ components, increases the max load moment of the MLC300. The position of the VPC-MAX™ counterweight is automatically positioned based on lifted load, boom length or boom and jib length and load radius.
