HF Series

Helical Parallel-Shaft Gearbox

HF series - Hoist drives are the new range of drive solutions dedicated for hoist and EOT cranes. The design of HF series has been framed by our synergetic R&D team after performing detailed data analysis of real operating conditions and conducting several interactions with many crane manufacturers to understand operating challenges faced by them to define needs for special design features which were incorporated in the products. The products are designed for higher FEM & ISO classes to have higher safety, high reliability also ensuring higher performances with precise operations for hoists. Additionally, the higher input to output offset and higher space between motor and drum installation provide an advantage to the crane manufacturers to choose from a wide range of drum sizes available in the market.
