A new range of High Performance Lifting (HPL) winches for Potain tower cranes are available from Manitowoc. The company claims the winches bring new levels of speed, control and efficiency to the industry. The winches have what Manitowoc describes as ”the latest in frequency-controlled technology”, offering optimised energy consumption combined with a greater choice of hoisting speeds.
Manitowoc said productivity is increased with the HPL winches, as lifting speeds are up to twice that of the older 75 LVF winch. It also said control is improved with creep speeds that are two times slower than the 75 LVF. These features, in combination with new motor brake management and new architecture that facilitates maintenance operations, mean the HPL winches not only speed up construction times, but also improve overall driving comfort, build quality and precision load placement, Manitowoc claims.
This improved performance comes with optimised operational costs, as power consumption is reduced and maintenance made easier, the company states. Additionally, with Power Control functionality, it is possible to limit the maximum amount of electric power required for operating a crane without impacting low-load and no-load working speeds.
The models in the new winch range are: the 75 HPL 25; the 75 HPL 30; the 75 HPL 35; and the 75 HPL 40. Rope capacities range from 539 metres to 956 metres, and they can be used with a wide range of Potain cranes, including the latest topless and luffing jib models from the company. Compatible models include: the MDT 349 L16; the MDT 389 L16; the MR 295 H16; the MR 225A; the MDT 249 J12; and the MDT 269 J10.
