Precision in movement

The ZF Friedrichshafen division Special

Driveline Technology is able to offer you a

wide range of machine drives, brakes and

clutches for applications in engineering as

well as customer specif ic drive solutions.

Our development and production activities are

focused on servo-assisted drives for automa-

tion engineering, two-speed drive gearboxes

for machine tools as well as customer-speci-

f ic drives, such as for printing machines,

robot applications and elevator gearboxes.

Our innovative standard products range from

low backlash servogearboxes (ZF-Servoplan),

and robust two-speed gearboxes (ZF-

Duoplan) to hysteresis clutches and brakes

for non-contact web control (ZF-Tiratron).

The ZF-Ecolift types RME 310 and 410 are designed for passenger and service elevators. The revolutionary design

for use in rope elevators, has distinct advantages over previously used gearboxes. Instead of using a worm gear,

ZF-Ecolift benefits from the inherent advantages of two-stage planetary gears to transmit motor power to the sheave.

ZF-Ecolift fulf ils the technical regulation for elevators (TRA 200) TRA 220-229 and the European elevator standard

DIN EN 81.

ZF-Ecolift is suitable for motor speeds of 1000 rpm, 1500 rpm (standard speed) and 3000 rpm. In frequency inverter

applications, speed can be increased or decreased referencing the standard speed .

This makes using multiple sheave sizes to achieve different speeds obsolete. Optimized gear tooth shape ensures

long-lasting, wear-resistant performance. Extensive lifetime durability tests prove the consistent load capacity of

ZF-Ecolift.

Low running noise thanks to helical planetary gearing.

High efficiency (96%) allows you to use smaller electric motors, reduced switch-on electrical power

ensures energy and cost savings.

Compact design.

High input speeds of up to 3000 rpm.

Cabin speeds up to 4 m/sec.

Allows cable double looping without additional support bearing.

Simple motor mounting.

Ease of maintenance means less downtime.

Low oil temperatures under full load and maximum speed.

Use of environmentally friendly organic oils possible.
