Manitowoc Launches Potain MCT 805

Manitowoc has launched a new high-capacity topless tower crane, targeting customers in Asia, Australia and New Zealand, the Middle East, Africa, and Latin America.

The Potain MCT 805, manufactured at Manitowoc’s Zhangjiagang, China factory, is similar to the MDT 809 and is available in 32t and 40t capacity configurations, with an 80m jib and a height under hook of 84m.

This high working height is achieved by the reinforced K-mast system with newly developed installation bases. An 8m cross-shaped base offers performance characteristics more commonly associated with a 10 m chassis.

The counter-jib no longer than 27.3m enables 7.5t capacity at 80m reach and the tip load of the M32 and M40 configurations is suited to meet the growing need for lifting heavier loads within confined job sites. The maximum 32t load capacity of the M32 version is available to distances of over 22m, while on the M40 version the 40t maximum load can be handled out beyond 18.5m.

Frequency-controlled hoists are available in a number of variations; the 150HPL80 on the M32, which can lift 1.8t at 151 m/s, and the 270LVF100 Optima on the M40, which can raise 3.5t at 162 m/s. For both the M32 and M40, a maximum drum capacity of 1,063m of rope is available if fitted with the larger hoist option. Customers can choose from a two-fall configuration on the trolley for faster lifting, or four-falls for heavy lifting.

The rotating section of the MCT 805 can be moved in either 10 or 11 loads depending on how the crane is being transported. All jib sections fit inside a standard container, making it a compact transport solution. This is possible due to the jib design measuring just 1.55 m wide and under 2.5m high. With its full 80m jib, the crane can be assembled to a 50m working height in less than three days.

The 8m cross-shaped base is also easier to set up than its 10m alternative. It consists of a main girder and two half cross-girders that connect with pins. Mast and jib section lengths have also been designed to match customer requirements, including the 10m mast for rapid erection, 5m mast for telescoping, and 3.33m mast for fine-tuning height.

The jib can be built up in 5m increments from 30m to 80m, either on the ground or in the air, depending on site conditions and available space. Its modular design without tie bars enables several configurations in addition to the lighter package weights.

The rotating cab and easy-connect points for the folding counter-jib further simplify erection. Once the wired towerhead/cab assembly has been fitted, there is no need to dismantle it between jobsites.

Thibaut Le Besnerais, vice president, brand, and product management for tower cranes at Potain Manitowoc said: “The advantages of fast assembly and compact design is really driving the growth in demand for topless cranes, but the growing popularity of modular construction methods is also creating greater need for higher-capacity models,”

“So the early success of the MDT 809 made it apparent that other regions served by our Zhangjiagang factory would also enjoy the benefits of its innovations, making the decision to launch the MCT 805 relatively easy. But those innovations don’t stop at performance, transport, and assembly – for instance, there are several new features that simplify servicing, such as the jib design that aids access to key crane components.”
