EPNMRV075 Aluminium Worm Gearbox \u2014 Overview<\/h2>\n

The EPNMRV075 aluminium worm gearbox is engineered for the challenging demands of material handling, elevator mechanisms, and construction machinery where a balance of compact weight (9 kg) and high radial load capacity (up to 7,380 N) is essential. Producing output torques as high as 261 Nm from inputs up to 3.0 kW, this model sees widespread deployment on scissor-lift platforms, overhead material transfer systems, and construction hoists across the Asia-Pacific region. The EPNMRV075 extends the IEC and NEMA flange compatibility range beyond the EPNMRV063 by adding 180TC acceptance, and its 28 mm output shaft directly fits standard lifting drum coupling bores without adaptors.<\/p>\n
