Abstract
A height safety trolley and modular rigid rail system for construction and maintenance personnel working at height is designed to allow continuous, smooth and fail-safe operation, for fall restraint and fall arrest, rope access and abseil. The height safety trolley has a connection arm, a clip body and a main chassis operably interfacing a rail engagement mechanism, movable between a rail engagement position to engage a rigid rail, and a disengagement position to disengage the rigid rail. The rail engagement mechanism may comprise integral pivot arms which close simultaneously inwards to engage the rigid rail and outwards to disengage the rail. As such, the trolley is easily and safely attachable and detachable at any position along the rigid rail.
