Product Description

Comparing to conventional crawler crane which requires bogey for superlift, 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 advantages are customers would reduce work and cost for ground preparation, lower ground-bearing pressure, and lesser counterweight.

Technical Specifications

The MLC300 features 96 m (315 ft) of boom and has the option of a fixed jib attachment of 30 m (98 ft). A 96 m (315 ft) luffing jib can be added to extend its reach to 144 m (473 ft). The VPC-MAX attachment increases capacity and boom and jib combination lengths. The MLC300 can raise 120 m (394 ft) of the boom with the VPC-MAX attachment and a boom and luffing jib combination of 168 m (551 ft).

Other features include:

Strongest load charts in its class
Common counterweight with MLC650
Upperworks and car body shipped deck (reduced set up time)
Raise full boom and luffing jib combinations without an assist (no outriggers)
Self-erect mast cylinder (reduced setup time)
Designed to be transported globally by optimizing component weights and dimensions.

Manitowoc release fixed-position for MLC300

Manitowoc has release news in February 2017 that they will be introducing a fixed-position counterweight on the MLC300. The crane will remain to have the same features as the original MLC300, just without the VPC.

The selling point was to market the compact footprint of the 300-ton crawler, without clients having to put in additional investment in the VPC. For this configuration, the VPC trolley and tray have been replaced by a two-position, stationary counterweight tray.

To simplify the MLC300’s design, the VPC system, and VPC-MAX preparation package are not included. Instead, all fixed-position counterweight will be retrofitted on the base crane. However, Manitowoc does have an aftermarket package available from Manitowoc Crane Care to update to a VPC system.

MLC300 will be available in the second quarter of 2017.
