A safety chain for conveyor pallets may comprise bent links arranged in alternating fashion with straight links. Each of the bent links may have two ends with a wheel disposed at each end. Each consecutive bent link and straight link may be joined at an articulation point. The safety chain may also comprise arms extending from each articulation point, wherein a conveyor pallet may be coupled to each arm. Further, roller guides that follow a trajectory of the safety chain may be arranged on one of two sides of the safety chain. The roller guides may rotate the wheels of the bent links. The articulation points enable rotation and position change of the bent links and the straight links so as to increase or decrease a distance between consecutive conveyor pallets according to a change of speed of a conveyor.

A moving walkway transit system having a moving walkway and a beltway control system for monitoring and controlling various operational aspects of the moving walkway. A method of using the beltway control system to operate and monitor the moving walkway.

An example drive system for a transportation system may include an actuator for transmitting an actuation motion from a motor, a first pulling device configured to transmit a pulling motion from the actuator to moving parts of the transportation system in a transition speed section situated between an embarking/disembarking zone and a middle zone, a second pulling device configured to transmit a pulling motion from the first pulling device to the moving parts of the transportation system in a high-speed section in a middle zone of the transportation system. In some examples, the first pulling device may be a carriage.

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.

A pitless and modular belt-type accelerating moving walkway transit system including at least three substantially identical walkway modules that are leveled and positioned atop a surface such as the ground, floor, road or deck. Each module has an endless belt moving at a different or the same speed wherein the at least three walkway modules are positioned linearly adjacent. Each module having one or more electric motors operably connected to an electrical source and handrails on opposing sides that move in synchrony with the endless belt of the same module.
