colour display. It can also
run the Terex T-link telematics function, which sends remote crane data over the web, giving instant diagnostics, operating data, machine status, and other key metrics to the owner. Maintenance and service needs can therefore accurately be based on factory recommended usage rates and wear: users can be sent automated maintenance notices, reducing downtime and keeping the machine in prime running condition and extending lifespan.
SIZE MATTERS We mentioned sheer size in our introduction. In April, Manitowoc announced the launch of the Potain MCT 1005 M50, the largest topless tower crane ever to be manufactured at its Zhangjiagang facility in China. It follows hard on the heels of
its MCT 1005, which itself was the company's largest model at its launch. It is designed for emerging markets and Southeast Asia and, boasting a huge 50 t capacity, the crane is available with three counterjib options that will further enhance its seamless integration into confined jobsites. The MCT 1005 M50 allows for the handling of eight tonnes at the end of its 80-metre-maximum jib, which is configured from 11 sections of either 5 m or 10 m in length. Only three sections are required to deliver its shortest configuration of 20 m, at which distance it can lift its full 50 t. The same maximum capacity is also available between 3.5 – 16.8 m when the jib is built to 80 m, or from 3.5 – 25.2 m when the jib is 30 m in length. There is also the option of configuring the crane with the 45 m jib, which delivers a hefty 24.8 t maximum capacity at the jib end. These heavy payloads are
supported with counterjib options 38 CRANES TODAY
Potain’s MCT 1005 M50 is its largest-ever topless tower crane from its Zhangjiagang plant
of 15 m for jib configurations of up to 45 m; 17.5 m for configurations of up to 55 m; and 20 m when working with jibs from 60 to 80 m. This versatility aids the crane’s ability to work in proximity to other cranes or nearby structures. Over 1,070 m of rope is available on the drum; smooth and precise frequency drives on Potain’s 25 DVFC 25 trolley efficiently transport the crane’s payload horizontally. Slewing speeds are set at between 0 and 0.7 rpm via the RVF 174 Optima+ system.
The K850 mast, of 2.45
m x 2.45 m sections, gives a freestanding height under hook of up to 69.7 m. At the top is the V140S Vision cabin. The entire top-slewing section can be delivered to the jobsite in as few as 11 trucks, offering a surprising ease of transportability for such a large crane. “As topless tower cranes
continue to increase in popularity, we are quickly responding to the demands of our customers in Asia-Pacific for higher- capacity models,” said
