Electromagnetic brakes are typically engaged promptly before speeds exceed 1.4 times the rated speed, after unintended reversal, or if the drive chain breaks, to engage the drive pedal (foot pedal) or chain and sprocket. Mechanical friction brakes. Using the load's inertia to decelerate and stop the escalator (moving walkway), maintaining stillness, while simultaneously or preemptively disconnecting the safety circuit.

　　 Electromagnetic brake Typically installed on escalators and inclined moving walkways with a lift height exceeding 6m, or equipped with public transport escalators and inclined moving walkways, or equipped with dedicated supplies for popular escalators and inclined moving walkways provided according to the contract.

　　Electromagnetic brakes are usually implemented in time before the speed exceeds 1.4 times the rated speed, after non-operating reversal, or when the drive chain breaks, to drive the tread (tread) or chain and sprocket. Mechanical friction brake. Use the inertia of the load to force the escalator (walkway) to decelerate and stop, maintain stillness, while or before disconnecting the safety circuit.

Electromagnetic brake

　　Electromagnetic brakes typically have block, disc and claw, tile, and tooth structures. Their commonality is to stop the rotating sprocket of the tread (tread).

　　As is well known, Electromagnetic brake The system is the lifeline of safe vehicle driving. With the updating and upgrading of automobiles, people's requirements for the safety, comfort, and economy of automobiles are getting higher and higher. The braking device that protects the safe driving of automobiles has gradually developed from the initial simple mechanical braking to the current ABS (Anti-lock Braking System) anti-lock braking system. However, ABS still has some problems, such as the difficulty in accurately measuring the speed of the vehicle body and wheels, and the difficulty in accurately controlling the braking force. These shortcomings make it possible for cars equipped with ABS to accurately meet the braking requirements under ideal road conditions, but it is difficult to meet the requirements on muddy mountain roads with poor road conditions. At this time, another auxiliary braking system is urgently needed to ensure the safe driving of vehicles. Electromagnetic brake technology, with its characteristics of no wear, fast response, stable braking, and good compatibility with the ABS system, has quickly established its position in the automotive auxiliary braking system.
