High Performance Lifting for tower cranes debuts

Manitowoc is launching an innovative new technology for its Potain tower cranes at bauma 2010 that that will introduce unprecedented levels of productivity for the industry. The first of Potain’s new High Performance Lifting winches will be introduced at the show. The new winches are designed for ultra-high-speed lifting, even when working in a higher number of rope falls.
Rémi Deporte, global product manager for mechanisms at Manitowoc, said the new winches offer substantial benefits for customers.
“This is a unique and patented technology that offers contractors significant time savings on general construction sites,” he said. “It is designed to work on cranes, in capacity classes that cover a broad range of projects. At bauma 2010, we will present the first model in a line of new winches. We see strong global appeal for these new winches, especially when contractors see the competitive advantages over other options.”
On display at bauma 2010 is the 75 HPL 30™, which can reach speeds of up to 225 m/min when working with two falls (or lines) of rope. The winch is the first in its class to break the 200 m/min barrier. It has a power rating of 75 hp (56 kW) and lifts 3 t per rope line. The 75 HPL 30 will replace Potain’s existing 75 LVF 30 Optima, which reaches a maximum speed of 116 m/min, only about 50 percent of the speed of the new 75 HPL 30™ winch.
Other winches will roll out in the coming months. Most will be 56 kW, but others will be offered in the 100 hp (75 kW) and 50 hp (37 kW) classes.
The new HPL Technology ™ winches have such high speeds because they use a double-winding motor controlled via a frequency converter. The technology is patented and exclusive to Potain cranes, and Manitowoc is the only manufacturer able to offer it.
Even when working with a greater number of falls (four instead of two, for example) the 75 HPL 30™ is faster than the majority of other winches on the market. And when working with more falls, it also has greater capacity.
The new winch will be offered with a range of tower cranes in the Potain line. It is best suited to cranes with 12 t capacity.
