MLC650 Manitowoc crane - load chart, specs & dimensions (2015 - 2026)

Crane Control System

The Crane Control System offers a user-friendly interface, two full graphic displays mounted horizontally for better visibility, a jog dial for easier data input and ergonomic joysticks.

Ease of use

The Crane Control System (CCS) features a user-friendly interface with all necessary crane control information within easy view on two display screens. A fully enclosed and insulated galvanized steel cab features power tilt and full-view glass for unmatched visibility.

Variable Position Counterweight (VPC)

The Manitowoc MLC650 features a counterweight system that 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 will be utilized on Manitowoc Model MLC300 as well as future new models.

Vpc-max

Capacity and boom and jib combination lengths can be increased through addition of the exclusive VPC-MAX attachment. The VPC-MAX attachment utilizes all of the standard VPC components, and only requires the addition of a 36 m fixed mast and the VPC-MAX beam. With the VPC-MAX attachment, the load moment of the MLC650 more than doubles its load. The position of the VPC-MAX counterweight is automatically positioned based on lifted load, boom length, or boom and jib length and load radius. The VPC-MAX components include: 36 m of No. 684 mast consisting of a 6 m butt, (2) 12 m inserts and a 6 m top. One additional swing drive (for a total of three) mounted on the adapter frame. Each swing drive is powered by a fixed-displacement hydraulic motor coupled to a planetary reduction gearbox and internal brake. The VPC-MAX system maintains optimum crane stability by automatically positioning crane counterweight behind the crane’s centerline of rotation based on lifted load, boom length and load radius.

MLC650 benefits

The MLC650 is designed to be transported globally with optimized component weights and dimensions. The MLC650 features a removable live mast shipping module and boom inserts designed to allow luffing jib inserts to ship within the boom inserts for cost-effective transport.

Productivity

Revolutionary Variable Position Counterweight (VPC) helps deliver class-leading lift capacities with less counterweight. The system works by automatically moving the counterweight into a maximized position for the given configuration and load case. No commands are necessary, so the operator is free to focus on the load and jobsite.

Engine

Cummins Model QSX15 Tier 4 Final diesel, 447 kW at 1800 rpm or Cummins QSX15 Tier 3 diesel, rated 447 kW at 1800 rpm. Includes pump drive disconnect for easier starting, engine block heater (240V), high silencing muffler or emissions compliant Tier 4 Final aftertreatment, hydraulic oil cooler, radiator and variable speed hydraulic controlled fan. The variable speed fan provides increased fuel efficiency, decreased engine loading, and reduced noise emission. Additionally, the multiple hydraulic pump drive transmission provides power for all machine functions. The system includes two 12 volt, 1375 CCA at -18° C batteries, a 24 volt system, and a 110 amp alternator. It features an 1117 L fuel tank, with a level indicator in the operator's cab. An optional cold-weather package with a heater for fluids is also available.

Hydraulic system

High-pressure piston pumps, driven by a multi-pump transmission, provide independent closed-loop hydraulic power for the hoisting drums, boom hoist, swing, left crawler and right crawler. A 946 L hydraulic reservoir is equipped with a breather, clean-out access, and an internal diffuser. Each function is equipped with relief valves to protect the hydraulic circuit from overload or shock. The system includes an oil cooler and replaceable, full flow return filters. All oil is filtered before entering the hydraulic reservoir.

Drums

Basic machine is equipped with two 1248 mm wide and 660 mm diameter main hoist drums, located in the boom butt and 4 m insert, and an 822 mm wide and 641 mm diameter whip drum, mounted in the rotating bed. Each drum is driven by a variable-displacement hydraulic motor through a planetary reduction system. The main hoist drum is grooved for 32 mm rope, while the whip drum is grooved for 28 mm rope. Powered hoisting and lowering operation is standard, featuring automatic (spring applied, hydraulically released) multi-disc brakes and drum rotation indicators.
