The feasibility of installing a lift is often thwarted by the depth required of the pit. With the Hiro 700 passenger lifts, an exceptionally shallow pit measuring as little as 30 cm is all that is required. Due to the unique patented counter weight drive system a simple single roller is mounted in the shaft head to enable smooth efficient 1:1 suspension of the lift car. Rope wear and electrical power consumption are both appreciably reduced.
