Two-stage planetary gearboxes up drive
efficiency
Two-stage planetary design of elevator gearboxes offers the advantages of higher efficiency (96%), reduced size and weight and low noise, when compared with 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 to 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

The ability of ZF's unique hysteresis brakes and clutches to perform precise tension control operations on larger systems has been enhanced with the introduction of new high power brakes.
Gearboxes speed machining centre assembly
The key to fast deliveries on AB Marwin machining centres is ZF's two speed gearboxes, which are an essential component in this approach.
The ZF-Ecolift RME 310 and 410 planetary drives are designed for cable type passenger and service elevators, and fulfil the technical regulations (TRA 200) TRA 220-229 and the European elevator standard DIN EN81.
Their revolutionary design, using two-stage planetary gears rather than wormgears, 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 3000 rpm enabling them to deliver cabin speeds of up to 4m/sec.

ZF appoints Home Counties distributor
ZF Industrial's unique range of hysteresis tension control products is now being supplied through DJ Automation, over an area centred on Bedfordshire.
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." ZF's Ecolift elevator drives are backed-up by the resources of one of the most respected manufacturers of driveline technology in the world.
ZF Industrial is part of the worldwide ZF Group of companies with production centres, partners and representatives on every continent.
In the industrial sector, ZF is at the forefront of developments, from individual units to complete systems solutions for all types of machinery and production units, including those used in robotic systems and the fast growing factory automation sector.
