Angle is less than between 15 ° of rigid guideway.Car size is easy to passenger to come in and go out or handling goods with structure type.Though traditionally its
Type of drive is how, using elevator as vertical transportation means of transport in building general name.By speed can divide slower elevators (1 meter/
It is second following), express lift (1 ~ 2 meter per second) and express elevator (more than 2 meter per seconds).19th century mid-term start occurHydraulic elevator,
So far still applied on low-rise building.1852, the E.G. Otis in the U.S. developed the safety cage of rope hoisting.
The eighties, drive device has further improvement, and such as motor drives winding reel, using balance weight by worm-drive.19
In the end of the century, frictional wheel drive is employed, greatly increase the hoisting depth of elevator.With the development of society, the utilization of elevator is more next
More popularize, even two or three layer of floor is fitted with elevator.For family, it is that can be achieved to install one motor
It is quickly upper to go downstairs, it is convenient for carrying article or people with disabilities.Vertical lift at present on the market is electric
Ladder is one motor of installation at the top of floor mostly, is lifted by belt or chain-driving motor, this elevator stability is bad,
Easily break down.
