摘要:
Example drive systems for handrails of walkways and moving stairs may comprise a plurality of carriages. In some examples, each carriage may comprise a body with several leading rollers that roll along a guide that defines a handrail path. The carriage may further comprise a locking/release mechanism for selectively coupling the carriage to a drive chain of the handrail. The locking/release mechanism may comprise a hook configured to move between an engagement position wherein the carriage is coupled to the drive chain and a disengagement position wherein the carriage is uncoupled from the drive chain. In some cases, a position of the hook may be controlled by a wheel that travels along a cam profile.

摘要:
A drive system for a transport system which has: actuation devices (400) for transmitting an actuation motion from at least one motor (410); first pulling devices (300) configured to transmit a pulling motion from actuation devices (400) to the transport system in a transition speed section situated between an embarking/disembarking zone and a middle zone; second pulling devices (300) configured to transmit a pulling motion from the first pulling devices (300) to the transport system in a high-speed section situated in a middle zone of the transport system.
