Elevator gearbox raises performance
stakes
The revolutionary two-stage planetary design of Ecolift elevator gearboxes offers higher efficiency, reduced size and weight and lower noise than conventional worm gear drives.
The revolutionary two-stage planetary design of ZF Industrial's new Ecolift elevator gearboxes offers the advantages of higher efficiency (96%), reduced size and weight and low noise, compared with conventional worm gear drives These advantages enable smaller electric motors to be used with the gearboxes, reducing initial equipment costs and also energy costs over the lifetime of the elevator system

Hydrostatic transmissions provide efficiency boost
The HC range of hydrostatic transmission systems provides improved fuel economy, reduced levels of noise and increased vehicle speeds.
The ZF-Ecolift RME 310 and 410 planetary drives are designed for cable type passenger and service elevators, and fulfil the technical regulations (TRA200) TRA220-229 and the European elevator standard DIN EN81.
Their revolutionary design, using two-stage planetary gears rather than worm gears, means that they are inherently more efficient in the way they transmit power.
Designed with an optimised gear tooth profile that ensures long lasting, wear resistant performance, the Ecolift units accept high input speeds of up to 3000rev/min, enabling them to deliver cabin speeds of up to 4m/s.
In addition, the Ecolift can be used in conjunction with frequency inverter drives enabling cabin speeds to be increased and decreased at will.
This type of system makes the traditional arrangement of using multiple sheaf sizes to achieve different speeds obsolete.
The Ecolift elevator drives are designed for ease of installation with large well-proportioned foot mountings and facilities which greatly simplify motor mounting.
The design also ensures ease of maintenance, which reduces downtime, and also optimised running with low oil temperatures under full load and maximum speed.
As an added benefit to users, the gearboxes can also be used with environmentally friendly organic oils, making the process of fluid disposal that much easier.
"The addition of Ecolift units to the ZF range enables us to extend the benefits of our planetary technology beyond the industrial automation marketplace", says Rob Pearson, Product Manager for ZF Industrial.
"The same advantages of high efficiency, size, and weight saving that are revolutionising industrial power transmission processes are equally relevant in the elevator sector, where traditional gearing technology is not providing the cost saving efficiencies demanded in the globalised market of the 21st century".
