The design of the walkwayapplied depends on the installation position.
·Different installation positions are divided into groups numbered 1 to 2.
·Figure 1 determines the installation positions of these groups in the railway line.
·The walkway has a locking system and shifting/sliding-prevent retractionunit.
Installation method Group 1 applies to the scenario without wind tunnel.
This installation does not be affected by the wind and wind caused by the passing train.
Installation method Group 2 applies to the scenario with wind tunnel.
This installation will be adjusted with ventilation (wind go through) rates of 30%, 20%, and 10% based on local requirement regarding to wind force level of wind environment in different region.
The loading class of walkway can be designed to A15、A50、B125(EN124-2015).
Flame retardant, antistatic, high strength
Non rusting, non discoloration, anti-aging
Convenient construction and maintenance
The cable can be controlled and communicated according to electric power
Layered laying of communications, anti-coupling
High temperature press SMC sheet molding compounds
Acid and alkali resistance, corrosion resistance
Avatar SMC Performance index
Anti slip pattern
Avatar cover of composite access covers achieved a market leading Skid Resistance Value of 89
The table below has been developed from data collected by County
Surveyors Society and illustrates the acceptabable parameters when tested using the TRRL Pendulum Test in general accordance with BS667:part 1:1986
This test provides a slip resistance value(SRV) for each surface tested The higher value the greater slip resistance.
TRRL Pengulum Value | Condition Of Surface |
19 and below | Dangerous |
20-39 | Marginal |
40-74 | Satisfactory |
Adove75 | Excelient |

ASTM G154a(Cycle 1) | UVA:340nm | 2,160hours |
ASTM G154b(Cycle 1) | Xenon Arc:340nm | 1,000hours |
ASTM G154(Cycle 3)c | UVB:Type313 | 2,160hours |
Results summary | ||
Average Flexural Strength Before UV aging (MPa) | Average Flexural Strength After UV aging (MPa) | Average Flexural Strength due to UV aging(%) (MPa) |
910 | 820 | 10 |
The loss of flexural strength was measured to be approximately 10%
Flame retardant grade
The flame retardant grade is FV0,(the highest grade of non-metallic mateials），and the smoke emission level is 15 when burned at high temperatures.The smoke is non-toxic,and the ttoxicity level is ZA1,which is considered safe ievel one.
