Potain MC 205B

The Potain MC 205B is a versatile tower crane from Potain’s City Crane range, combining strong lifting performance with flexibility and efficient transport. It offers a maximum lifting capacity of 10 tonnes and a maximum jib length of 60 meters, delivering a tip load of 2.4 tonnes at full radius. This makes it well-suited for a broad range of construction projects, from commercial buildings to infrastructure works.

The crane supports multiple jib configurations between 30 and 60 meters. For instance, at 40 meters it can lift 5.1 tonnes, and at 50 meters it handles up to 3 tonnes. At 55 meters, its capacity is 2.7 tonnes, and at maximum reach (60 meters), it lifts 2.4 tonnes—providing consistent performance across a broad working radius.

Mounted on a 2 m x 2 m mast system (VB 20 A), the MC 205B offers freestanding heights over 64 meters, and it supports internal climbing configurations for high-rise applications. It can be anchored using climbing devices such as the BA 66A and can reach climbing heights of over 200 meters when properly supported.

Mechanically, the crane is powered by the 55 RCS 25 hoisting winch, which provides speeds from 20 to 80 m/min depending on load. The winch is rated at 55 hp (40.5 kW) with a rope capacity of 557 meters. Trolley movement is handled by a 5 D3 V4 system offering speeds of 15, 30, and 58 m/min, and slewing is managed by dual RCV 145 motors, providing rotation speeds up to 0.8 rpm. The rail-travel mechanism is the RT 544 A1 2V, powered by 4 x 5.2 kW motors, capable of speeds between 13.5 and 27 m/min.

The base ballast requirements vary based on height and configuration but typically use modular concrete slabs of 4800 kg, 4200 kg, and 3400 kg. The counter-jib remains compact at 14.5 meters, allowing for tight jobsite maneuverability. The electrical system operates on 400 V, 50 Hz, with a power demand of 75 kVA.

Certified to FEM 1.001-A3 and ISO 9001, the Potain MC 205B meets modern performance and safety standards, making it a dependable choice for contractors requiring a balance of lifting power, compact footprint, and configuration versatility. It is particularly effective in dense city construction and projects with limited crane headroom or interference constraints.
