Lx2000

Useful Documents

The Lx2000 is designed specifically to add power to elevator performance. Built to L&T’s stringent quality standards, the Lx2000 is tested and certified to meet global benchmarks, thus giving you the assurance of total reliability.

It handles loads up to 22kW, and is engineered to keep your elevator operating at optimum efficiency, even in the hot, humid and dusty conditions that characterise India’s industrial environment.
