Main control system

Advanced 32-bit microprocessor is introduced to serve as the core

and the other three new type 8-bit microprocessors are used to

serve as the standby controllers.They cooperate with the monitor

each other,ensured accurate and reliable system control,and

stability and comfort during highly safe running.

Driving System(40% Resource reduced)

Its using permanent magnet synchronous gearless electric motor

driving which needs no lubrication and costs less power and tech-

nique of changing frequency by converter.Compared with the

previous worm-and-gear driven lift,it improves its transmission

efficiency from 55% to 95% reducing 40% of resource.

There is built in group controlling system directed by in the

controller,which is able to control four system and 45 building at

the same time witout requiring adding any equipment.

Directed by operation of tree structure in chinese interface,the

controlling system which has a sound fault monitoring and recor-

ding functions can largerly shorten the time for trouble shooting.

Compared with traditional lift,METIS series cansave the mainte-

-nance cost as it needs no maintenance and adding of oil.

A new type of high speed and high efficiency products in METIS

series is developed by Royal Lifts company ,which vacates 50%

of engine roomacre-age,reduce customer's constructional cost

and perfectly matches appearance of the building by adopting

advanced technique.
