Abstract: 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.

Abstract: A braking system for escalators and moving walkways, includes a braking device (3) with a main brake (30) of the type which is released when there is no voltage in its electric activator, and an auxiliary brake (31) of the type which is closed when there is no voltage in its electric activator. A controller (1) controls the braking device (3), prepared for obtaining the load of the escalator or moving walkway, and calculates the braking torque required for each braking device (3) depending on the load and activating the braking device (3) for obtaining the corresponding torque while braking when a braking command is received. The auxiliary brake is activated (32) for taking the escalators or moving walkway to a safe position when there is a system failure.
