Escalator machine, High efficiency, 15kw -33kw, for metro
escalator, indoor application
The operation of the escalator is powered by the escalator machine
which make the step band system and handrail system operate and
transport passengers.The machine is the core part of the escalator,
mainly composed of motor, reducer, brake, safety switch, electrical
interface, etc. As the core and safety component in escalator, it's
strong required the product quality and safety. After long-term
operation of the escalator, the worm gears have been worn out, the
motor and other parts were reached their service life, the machine
must be replaced properly and timely to restore its quality, safety
and effective use of the product.
Normally, metro customers are required to have high efficiency
machine to save energy. The hypoid-helical gear machine with high
efficiency to meet customer special requirement. Also, there are
some special features request from metro customers are as option
cover by this type of machines, like brake lining worn sensor, oil
temperature, etc.
The teeth no of machine sprocket is base on escalator system design
to specify per contract.
