Opencast mining

Opencast mining

In the field of opencast mining, we provide drive solutions including:

cylindrical – planetary gearboxes and drive units for belt conveyors
gearboxes to drive bucket wheels of bucket wheel excavators and stacker-reclaimers
planetary-worm gearboxes to drive the slewing boom of bucket wheel excavators and stacker-reclaimers
planetary-worm gearboxes for tracked (crawler) drives as well as other technological vehicles

Our FBWG250, FBWG500, FBWG1000 and FBWG2x500 bucket wheel drive gearboxes have a power range from 250kW to 1000kW and gear ratios from i=147 to i=231. These gearboxes are equipped with forced lubrication systems and oil heaters. The weight of the largest one is 36 tons, and the torque on the output shaft reaches 2.23 MNm. All gearboxes in this group are highly specialized, proven solutions and have been equipped with an advanced diagnostic system monitoring their operation (with the option of offering remote supervision to the customer).

Your advantages:

compact size and favorable power density factor
FBWG250, FBWG1000 and FBWG2x500 gearboxes in the construction of the excavator provide the function of the support bearing of the bucket wheel,
forced lubrication system equipped with a duplex oil filter,
the FBWG2x500 gearbox is equipped with a reliable system of protection against overload through blocking the bucket wheel
high durability and reliability
possible operation in a dusty environment
possible operation at sub-zero temperatures
possible replacing the angular stage without dismantling the gearbox and unscrewing the body
system for monitoring the condition of the gearbox and the systems installed on it (also a remote monitoring option)
toothed gears made of MQ class material according to ISO 6336-5
rolling bearings from reputable manufacturers only

The FSP700, FSP860, FSP950, FSP1200 planetary-worm gearboxes feature very high ratios reaching i=840. Despite the fact that torques reach up to 2MNm, they have compact dimensions. This is possible due to the use of a worm stage and two epicyclic stages in their design/construction. Depending on the application, they can be equipped with forced lubrication systems and parking brake systems.

Your advantages:

compact dimensions and low weight in relation to the transferred torque
wide range of ratios
silent running
high durability and reliability
possible operation in a dusty environment
possible operation at sub-zero temperatures
possible operation in reversible motion
toothed gears made of MQ class material according to ISO 6336-5
high efficiency/performance
rolling bearings from reputable manufacturers only
