Alimak SL 500 / SL 1000 Hoist
Permanent Rack-and-Pinion Service Elevators for Industrial Structures
The Alimak SL series is a compact, robust, and permanently installed industrial service elevator designed to improve plant access, uptime, and operational safety. Built using Alimak’s proven rack-and-pinion technology, the SL 500 and SL 1000 are ideal for vertical access on chimneys, silos, bridges, tunnels, towers, and other demanding industrial structures.
Available in two configurations with payloads of 500 kg and 1,000 kg, both models operate without the need for a shaft or machine room — making them highly versatile and easy to install even in retrofit applications.
