The Sleeper Layer SL550 allows up to 5 adjacent sleepers to be placed simultaneously. Lifted into position, their correct placement is ensured by a precision gauging hydraulic system that spreads the sleepers to the desired distance up to a maximum of 765 mm (30 in). The system has been extensively tested and provides excellent results in sleeper alignment, spacing, and positioning.
A major benefit of the SL550 is that the sleepers do not move sideways when the grab is released, ensuring precision placement and minimising risk. It has also been engineered to support the lifting of sleepers straight up from the ground without preparation.
