Therefore its potential safety hazard can not be ignored.
GB 16899-1997-7.1 specify manufacture and the installation safety standard requirements handrail of escalator or moving sidewalk
The speed of service of band is 0 ± 2% Machine Design franchise relative to the speed franchise of step, pedal or adhesive tape, is considered
The factor such as friction system and driving error, general actual error are likely to be breached ± 15%.General design is, handrail tests the speed dress
Put detection handrail tape running speed, control system receives the rate signal of hand strap velocity measurement device transmission, at the same with step or step on
The speed of plate is contrasted, once contrast after error information not certain numerical value scope (below all as a example by ± 15%) with
It is interior, then make escalator or moving sidewalk out of service immediately, it is to avoid handrail is too advanced or lags behind step, pedal
The speed of service makes the handss of people and foot speed asynchronous, so as to passenger is placed in dangerous circumstances.
Accurately tachometric survey can lift the safe operation coefficient of escalator or moving sidewalk, and handrail is run
Speed and step or the error amount of the pedal speed of service, and escalator and moving sidewalk should be made after reaching error amount
Response, GB is not distinctly claimed, and the design of each manufacturer is also slightly different.
The handrail speed measuring device that the country is usually used at present mainly has two kinds, and hand strap velocity measurement device is directly welded by one kind
It is fixed on truss, another kind is the Weight type handrail speed measuring device using lever principle, by the gravity of lever one end weight
