Manitowoc has expanded its range of topless cranes with the launch of the Potain MCT 275 to deliver easier transport and assembly, high efficiency and reliability.
To respect social distancing, the company unveiled the crane during a virtual launch event at Manitowoc’s factory in Zhangjiagang, China on July 29, where the 10 t version of the MCT 275 was displayed with its full 70 m jib.
The new 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.
Manitowoc Regional Product Manager – Tower Cranes Kwong-Joon Leong said 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 job sites.
“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,” Leong said.

“With its standout 70 m jib, we believe this crane will appeal to a wide range of companies and projects.”
On a well-prepared site, the MCT 275 can be setup within one and a half days, with the full jib and counter-jib erected in four lifts. The complete upper part of the crane can be transported in six containers.
It is designed to work with a 2 m by 2 m L68 mast systems and can be used 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.
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 offers 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 offers 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 offers a rope capacity of 766 m and can lift 1.5 t at up to 114 m/min. The 75 HPL30 is a55 kW-rated hoist that offers a rope capacity of 845 m and can lift 0.2 t at up to 220 m/min.
The MCT 275 will ultimately replace the MC 235 model, a long-serving hammerhead top-slewing crane with a proven history of customer satisfaction.
