Conveyor travelator moving walkway reversal causes and operating speed
1. Electrical risk source
The wrong phase of power grid, phase breakage, loss of voltage, etc. cause the motor to reverse or drive force is insufficient, resulting in the reversal of the moving escalator, especially under the working condition of heavy load moving; the low-voltage components or devices occur short circuit, adhesion, breakage and other faults, or the safety circuit, brake to Michael control the telephone circuit and other faults, so that they fail and cannot play the role of protection, control, stopping, etc., so that the escalator reverses.
2. Mechanical risk source
The driving chain between the driving device and the step sprocket breaks and causes reversal; the chain driving the step breaks and causes reversal, the escalator is seriously overloaded and causes the motor torque to be insufficient and causes reversal, the belt used for driving between the driving device and the step sprocket slips and causes reversal, the escalator and the moving walkway suddenly fail in operation and cause an emergency stop, and the working brake cannot provide sufficient braking torque and causes reversal.
Step speed of conveyor travelator moving walkway.
The speed range of the conveyor travelator moving walkway is from 27 m/min to 55 m/min. An escalator moving at 44 m/min can carry more than 10,000 people in one hour, which is much more than the number of people carried by a standard elevator.
