The Potain MDT 109 is part of the CCS City Range line cranes that have been redesigned using the latest technology and machinery to ensure better performance. This crane has a maximum lifting capacity of 6 metric tons (6.6 U.S. tons). The jib can extend to 55 m (180.4 ft.) and the height of the mast reaches up to 55.1 m (180.8 ft.). The MDT 109 can lift up to 1.35 metric tons (1.5 U.S. tons) while at its maximum length. The bases, mast, and climbing equipment are interchangeable with some other top-slewing tower crane models.

The MDT 109 features the new Manitowoc Crane Control System (CCS) which helps the operator get more work done faster and with greater precision. For instance, the CCS provides increased load chart with the maximum speed potential, the operator can configure the crane in 15 minutes, calibrate sensors for crane movement, set the trolley limit switch, and set jib length. There are a handful of features which make operating the crane easy such as a power control limiter, top zone tracing, and a crane configuration optimizer to help maximize productivity and save time.

This model comes equipped with Potain’s exclusive Ultra View which has a complete new driver control unit for enhanced ergonomics and comfort. The MDT 109 is designed to simplify installation to reduce the time needed to put the crane in service. Crane sections are compact and can be folded for easy transport to the jobsite.
