Speed protection (patent number: ZL201310487786. X)

When the operating speed of the overhead passenger device is lower than 20% of the design speed or higher than 20% of the design operating speed, that is, when there is underspeed or overspeed phenomenon
The system will automatically protect parking.

Slipping protection

After the operation of the overhead passenger device, when the speed detection of the driving wheel is inconsistent with the speed detection of the supporting wheel, the electronic control device will control the equipment to stop due to a malfunction, and the voice will broadcast "slip protection", and the touch screen will display "slip protection action".

Oil temperature detection protection

When the oil temperature of the gearbox or oil tank exceeds the set maximum value, the equipment will automatically stop running.

Full line emergency stop protection

During the operation of the overhead passenger device, emergency stop devices for sudden events are installed throughout the entire tunnel, and alarms are issued by segment numbers to ensure passenger safety. It can also serve as an on/off device for debugging and maintenance of overhead passenger devices.

Patent number for tension reduction protection: (ZL201620632668.2)

When the tensioning hammer lands due to reasons such as traction steel wire rope or loose tensioning steel wire rope, the traction steel wire rope will lose its constant tension. At this time, the protection switch will act and the system will automatically protect the parking.

Anti detachment rope protection (patent numbers: ZL201721035024.6, ZL201720709012.0)

1. Body anti detachment rope protection
Install anti detachment rope barriers along the line to prevent the steel wire rope from falling off the supporting pulley. At the same time, set up a rope detachment protection device. After the steel wire rope detaches from the groove of the supporting pulley, the protection switch will be triggered, and the system will automatically stop. At the same time, a rope catcher will hold the traction steel wire rope to prevent it from continuing to fall.

2. Head and tail anti detachment rope protection

There are three forms of protection:
① Design of widened edges for drive wheels and roundabout wheels;
② Install anti slip rope protectors below the driving wheel and the detour wheel;
③ Install anti detachment rope pillars below the driving wheel and the detour wheel.
The width of the widened wheel edge is greater than the diameter of the steel wire rope, which can prevent the steel wire rope from continuing to fall. When there is a situation where the steel wire rope enters a large object between the wheel body or the swing amplitude of the suspension chair is large, the steel wire rope falls out from the edge of the driving wheel and falls into the anti slip rope protection ring, which prevents the steel wire rope from continuing to fall. When the protective ring is not working, the anti slip rope column below can prevent the steel wire rope from moving rapidly towards the middle of the monkey cart, thereby minimizing personnel injury.

Slope change point anti fall rope protection (patent number: ZL201320509226.5)

Using a multi support rope wheel set (double or four support wheels), the force is evenly distributed, and the positioning is automatically adjusted, suitable for different slope changing points. The slope change point is equipped with a rope fall protection device (i.e. rope catcher and rope fall sensor). Once the steel wire rope falls off the track, the overhead passenger device will automatically stop after the rope catcher catches the rope, ensuring personal safety.

Broken axis protection (patent number: ZL201520241556. X)

When the drive shaft breaks, the drive wheel can be kept in its original position, that is, it will not fall off, the traction wire rope will not loosen, and the sensor will send a stop signal to stop the machine. At this time, passengers will not fall and will not endanger personal safety.
Drive pressure high and low pressure protection
When the driving pressure exceeds the maximum (factory set value of 20MPa) or is lower than the minimum (factory set value of 2MPa) set value, the electronic control system will sound and light an alarm "Drive pressure too high protection" or "Drive pressure too low protection", and the system will stop running.
G-type offside protection (sensor form)
If the passenger fails to get off the aircraft in a timely manner at the nose or tail exit points, and crosses the over limit protection point, under the action of gravity, the steel wire rope touches the signal wheel, and the system detects the signal and automatically protects the parking.

H-type offside protection

If the passenger fails to get off the plane in a timely manner when they reach the exit points at the front and rear of the plane, and when they cross the offside protection point, the protection switch will be triggered, and the system will automatically protect the parking.

Anti swing device

1. Roller anti sway device
This device can effectively prevent the suspension chair from swinging left and right (especially when the suspension chair swings towards the center of the tunnel), and the supporting rope wheel blocks the suspension chair, instantly flipping it upwards and causing personal injury accidents. This device is only suitable for G-type and HK type slings, and HM type slings cannot be used.

2. Full line anti swing device

Install a steel wire rope on the entire road below the support wheel. When the suspension chair experiences excessive sway, the anti sway steel wire rope will block the suspension chair back and restore it to its normal position.

Passenger distance control device

In the past, incidents of flying and injuring people in "monkey cars" mostly occurred in overhead passenger devices with detachable suspension cables, where passengers did not ride according to the designed distance between passengers, resulting in serious overloading. This device can effectively control the distance between passengers of the detachable suspension cable and avoid overloading during operation.
