The new Potain MCT 275 is the latest launch from Manitowoc, expanding the company’s popular MCT range of topless cranes built in China. This new model has been designed for easier transport and assembly, plus high efficiency and reliability on construction projects.
The crane was launched yesterday (29 July) during a virtual launch event at Manitowoc’s Chinese factory in Zhangjiagang, where the 10 t version of the MCT 275 was displayed with its full 70 m jib. This model has taken advantage of the advances and innovation Manitowoc made with the introduction of the MCT 325 and was largely been inspired by it.
“With the increasing popularity of precast concrete construction, topless cranes like the MCT 275 are becoming the go-to solution for the speed and simplicity they bring to jobsites,” said Kwong-Joon Leong, regional product manager for tower cranes at Manitowoc. “The topless design allows multiple units to overlap on site and with the MCT 275 we’re giving customers a new choice in the 10 t and 12 t range. With its standout 70 m jib, we believe this crane will appeal to a wide range of companies and projects.”
Available in two versions, the MCT 275 features jib length configurations from 30 m up to 70 m, in increments of 5 m. At its 70 m jib end, the MCT 275 can handle 2.3 t for the 10 t version and 2.2 t for the 12 t version, making it an excellent performer for long-distance lifting.
According to Manitowoc, the MCT 275 can be set up within 1.5 days on a well-prepared site, with the full jib and counter-jib erected in four lifts. The complete upper part of the crane can be transported in six containers.
The MCT 275 is designed to work with the 2 m x 2 m L68 mast systems and can be utilised with fixing angles on a regular high-rise construction project. Users can also assemble the crane in an internal climbing configuration or mounted on a chassis, for maximum versatility.
In addition, customers have a variety of options for the hoisting, slewing and trolley mechanisms. The 10 t version offers the 60 LVF25 as standard and the 75 HPL25 as option, while the 12 t version offers the 75 LVFC30 as standard and the 75 HPL30 as options.
The 60 LVF 25 is a 45 kW-rated hoist that has a rope capacity of 500 m and can lift 2.5 t at up to 88 m/min. The 75 HPL25 is a 55 kW-rated hoist that features a rope capacity of 834 m and can lift 0.35 t at up to 215 m/min. The 75 LVFC30 is a 55 kW-rated hoist that provides a rope capacity of 766 m and can lift 1.5 t at up to 114 m/min. The 75 HPL30 is a 55 kW-rated hoist that has a rope capacity of 845 m and can lift 0.2 t at up to 220 m/min.
In 2014, Manitowoc launched its first Potain topless crane from the Zhangjiagang factory, the MCT 385. Over the years, the company has continued to innovate and added the MCT 205, MCT 85, MCT 325, MCT 565 and now the MCT 275 to complement the range. Manitowoc said the MCT 275 will ultimately replace its popular hammerhead top-slewing crane model, the MC 235.
