Potain MR 150

The Potain MR 150, introduced as part of Potain’s MR series of luffing jib tower cranes, is tailored for projects in dense urban areas where over-slewing is restricted and lifting precision is essential. It features a maximum lifting capacity of 10 tonnes at reduced radius and can handle 2 tonnes at the full 50-meter jib extension. The crane is capable of operating with jib lengths ranging from 30 meters to 50 meters, with intermediate configurations at 35, 40, and 45 meters. The lifting capacity varies accordingly—4.6 tonnes at 30 meters, 3.6 tonnes at 35 meters, 2.65 tonnes at 40 meters, and 2 tonnes at 50 meters.

Its luffing jib reaches a maximum angle of 75° and is supported by a 55 RCS 20 or 25 hoisting winch, offering speeds up to 104 m/min for lighter loads with a 40 kW motor output. The luffing motion is driven by the 75 VTV 50 winch with a cycle time of approximately 1 minute and 36 seconds, delivering fast and controlled movements. Slewing is facilitated by the RCV 145 motor with a speed up to 0.8 rpm, ensuring smooth and precise operations in tight environments.

The MR 150 mounts on either 1.6 x 1.6 meter or 2 x 2 meter mast sections and can be installed on different base systems including the 4.5 m and 6 m cross base configurations. Maximum free-standing heights depend on the tower type used, with K407 and K607 series allowing a range of heights from approximately 12.7 meters up to 57.7 meters. Electrical supply requirements are 400V at 50 Hz, consuming about 150 kVA, making it suitable for most construction site power standards.

This crane’s compact slewing radius and variable jib positioning make it ideal for inner-city construction or jobsites surrounded by other high-rise structures. It incorporates Potain’s precision hoisting, slewing, and luffing mechanisms for reliable, operator-friendly performance in demanding conditions.
