10.Direction reversal protection
When it comes the unintentional reversal of the direction of travel, the escalator (auto-walk) will automatically stop the operation.
11.Security line
The yellow synthetic resin security line is located in the front position and two sides of the escalator tread so that the passengers will not need in-between the edge of the adjacent step. The security line on both sides of the step is higher than tread surface. (The auto-walk offers the selective yellow spray-painted security line.)
12.Emergency button
When the button has been pressed down, the escalator (auto-walk) will stop the operation.
Additional safety devices
13.Upper and lower protection plates in the machine room
During inspection and maintenance, it could prevent operators from being involved in stairs or foot boards.
14.Brake protection
When the electric brake function fails after being tested, the brake function goes into effect by the safety device through the spring resilience action. In this way, the escalator (auto-walk) stops the operation.
15.Safety inspection switch
It is a safety device to prevent from the escalator starting during the inspection and maintenance.
16.Illumination
Illumination exists in the upper and lower ends of the escalator, in the lower part of the step in order to remind passengers of the security matters.
17.Alarm bell starting device
The alarm bell rings when it starts the escalator in order to remind the passengers of the security matters.
18.Cutoff device for handrail breakage
When the handrail is broken, the escalator will automatically stop the operation.

Rational Civil Engineering Layout · Precise Integration with Building Structures
To ensure efficient integration between equipment and building structures, we provide complete public escalator civil engineering layout drawings and technical support, including:
Scientific coordination between civil works and equipment design effectively reduces on-site construction difficulty while improving installation efficiency and overall aesthetics.
Diverse and Feasible Layout Solutions
To accommodate different passenger flow organization requirements, a variety of proven and practical layout solutions are available:
Single unit arrangement
particularly suitable for transporting passengers between two floor levels,where passenger flow is in one direction,althoughon-demand starting can be utilized to allow travel in both two directions,(e,g,up in the morning and down in the evening).
Continuous arrangement(one travel direction)
Mainly suitable for small department stores,between three sales floor levels,More space required than the interrupted arrangement.
Interrupted arrangement(one trauel direction)
Passengers have to make a short detour to the next escaletor, strategically placed displays alongside the route of this detour can help to increase sales by encouraging impulse buying.
Multi-level parallel arrangement(interrupted traffic,two travel directions)
Mainly used in department stores and public buildings with a heavy traffic flow,When there are three or more escalators,the possibility to reverse the direction of travelof both escalators depending on the usage or traffic flow,this arrangement is economical,since no decorative truss cladding required.
Multi-level criss -cross arrangement(continuous traffic flow,two travel dirctions)
Mainly used in major department stores,public buildings and public transportbuildings,reduce congestion at the landing area by separating upwards and downwardstravelling passengers.
These solutions can be flexibly applied to various spatial structures and traffic demands, ensuring efficient, safe, and orderly passenger movement.
From product technology and functional configuration to safety systems, civil engineering layouts, and overall planning, our escalators and moving walks are not merely transportation devices, but reliable, long-term system solutions for public spaces.
Through professional design and high-standard manufacturing, we provide safer, more efficient, and more durable vertical and horizontal transportation support for modern public transportation systems and architectural environments.
