Manitou MT 6642T

September 28, 2010

Manitou’s MT 6642T is what Manitou North America considers the heart of the construction lift-and-place product line. The MT 6642T is a bare-bones utilitarian telehandler aimed at contractors and rental operators. Based on the notion that the machine has been designed to lift palletized materials to increased heights, the boom features a smaller gooseneck and a different attachment system than Manitou’s ground-engaging products.

The high-pivot boom on the MT 6642T is mounted close to cab height to provide improved visibility to the rear of the machine. The boom is a four-plate box design. Boom strength comes from the thicker specked top and bottom plates and is elevated by dual lift cylinders. Although the extension cylinder is internal, which Manitou says provides better protection, the hydraulic hoses are housed in a fully enclosed external carrier. Everything is located within the beefy frame of the machine. “On jobsites, people occasionally back or bump into things, so we try to minimize any potential for damage,” says Ryan Ford, product specialist for Manitou North America.

A Tier 2-compliant 99-hp John Deere 4045T diesel engine (Tier 3 coming soon) is currently standard on the MT 6642T; a Tier 3-compliant 115-hp John Deere 4045T is optional. The machine features Dana Spicer axles and a Dana T12000 powershift transmission with three speeds forward and reverse. The rear axle stabilization system and 10° frame leveling are standard. On the RAS system, any time the boom is elevated above 60°, the axle locks, the brake is set, and the transmission shifts into neutral.

The engine on the MT 6642T is located mid-frame and inline. It can be accessed through two sliding panels, or the cover can be removed for full access. The hydraulic tank can be found hidden within the frame, which negates the potential risk of mixing it up with the fuel fill point located along the side of the frame opposite the cab. Also on the side of the frame is the battery box and a small tool storage area. Outriggers are available as an option, which provide additional stability and allow for the maximum forward reach capacity to be doubled in some reach configurations. The frame comes ready for outriggers to be field-installed.

The MT 6642T’s cab has everything you need and nothing more. A suspension seat is optional, and a fully enclosed cab with heater is also available. Boom functions are controlled by twin pilot-operated fully proportional joysticks.

Although it is manual, the quick-attach system only requires the operator to climb out of the cab once to change attachments. Once manually released, the locking plate automatically secures the attachment in place. Auxiliary hydraulics is an option, as well as attachments, such as tilt and swing carriages and an auger. Other options include a fully enclosed cab, work platform safety system, and a radio remote control option for fully proportional movements of the boom to operate up/down and telescope in/out, as well as to start and stop the machine.
