Potain unveiled the MCT 325 flat top tower crane at an event held at the Manitowoc group production facility in Zhangjiagang, China yesterday.
The MCT 325 comes in two basic versions with 12 and 16 tonne maximum lift capacities and jib lengths from 40 to 75 metres. As with other MCT cranes the 325 has been designed for easier transport and assembly, and more efficient operation.
The new crane is designed to work with the company’s two metre square L68 and L69 tower systems and can be used as a tied in external crane, in an internal climbing configuration or mounted on a chassis in order to provide maximum versatility. The MCT 325 will eventually replace the traditional MC 310 hammerhead tower crane. Shipments are due to begin in September and will be sold across the Asia Pacific region, the Middle East, Africa, South and Central America as well as Russia and CIS countries.
The new crane also features a new square design counter jib concept, which is said to simplify assembly on site, the complete jib and counter-jib can be erected in two lifts each and include dedicated slinging points on the counter jib and transport brackets on the jib to facilitate easier loading and installation. The jib can be extended from 40 metres to the maximum 75 metres in increments of five metres. Capacity at the 75 metre jib tip is 2.5 tonnes on the 12 tonne model, and 2.3 tonnes on the 16 tonner.
A variety of hoist, slew and trolley mechanisms are available, the 12 tonne version comes with the standard 75 LVFC 30 winch with a rope capacity of 766 metres and can lift 1.5 t at speeds of up to 114 metres a minute, there is also an option to upgrade to the 75 HPL 30 hoist.
The 16 tonne crane comes with the 75 LVFC 40 winch as standard, with the option to upgrade to the 75 HPL 40 or 100 LVF 40 which offers a rope capacity of 637 metres, and speed of up to 90 metres a minute with a two tonne load. A safety brake option is available for all of the winches.
The company says that on a well prepared site, the MCT 325 can be erected within a day and a half.
Potain regional product manager Kwong-Joon Leong said: “We are delighted to add the MCT 325 to our range, just 18 months after we launched the MCT 565, the largest topless crane in Potain’s Asia range.”
“Topless cranes like the MCT 325 are becoming the go to solution for projects utilising precast concrete, which is an increasingly popular choice for the speed and simplicity it brings to job sites. Topless cranes also bring speed and simplicity to projects thanks to their design which allows multiple units to overlap on site. The MCT 325 gives our customers a new choice in the 12 and 16 tonne range. And with its standout 75 metre jib, we believe this new model will appeal to a wide range of companies and projects.”
The first Potain topless crane from the Chinese plant was the MCT 385, which was launched in 2014, since then the company has added the MCT 205, MCT 85, MCT 565 and now the MCT 325 to the range.
