MLC300 Manitowoc crane - load chart, specs & dimensions (2015 - 2026)

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 new models.

Variable Position Counterweight

The Variable Position Counterweight system, with only rotating bed counterweight, maintains optimum crane stability by automatically positioning crane counterweight based on boom length and load radius. No carbody counterweight is required. The crane can be equipped with 175 200 kg of upperworks counterweight made up of a single piece counterweight tray and sixteen 10 t counterweight boxes or with 215 200 kg of upperworks counterweight with 2010 t counterweight boxes. Left and right side counterweights are interchangeable and common with the Model MLC650 counterweight.

Vision operator’s cab

The Vision Cab™ is a fully enclosed and insulated galvanized steel module mounted to the left front corner of the rotating bed. The module is equipped with power tilt, a sliding door, large safety glass windows, front and roof windshield wipers, a dome light, a sun visor and shade, a fire extinguisher, air conditioning, swing and travel alarms, and a radio/CD player. The operator’s station swings over the front of the rotating bed for transport. Optional features include nylon protective window covers.

Vpc-max

Capacity and boom and jib combination lengths can be increased through addition of the exclusive VPC-MAX attachment. The VPC-MAX attachment, utilizing all of the standard VPC components, increases the max load moment of the MLC300 when a 30 m fixed mast, VPC-MAX counterweight beam. The position of the VPC-MAX counterweight is automatically positioned based on lifted load, boom length or boom and jib length and load radius.

Jobsite benefits
