We offer a wide range of gearboxes intended for driving the armoured and belt conveyors. They are adapted to work in underground mines in the Ex I M2 explosion hazard zones.

We supply gearboxes for driving face conveyors in a coaxial version (FP series) and in an angular version (FKP series) in the power range from 160kW to 1000kW. The ratios of these gearboxes comply with the recommendations of the “RAG N 335 000” standard. This gives the user considerable scope and great freedom to diversify the drives based on the reliability index and price. Our solutions are provided with efficient cooling systems that have been tested in difficult conditions and whose possible replacement or other service activities do not require the gearbox to be dismantled (removed). Lubrication of the gearbox key nodes based on the splash system ensures high reliability and fulfills its tasks in the full range of loads, while in the case of specific customer requirements, it is possible to reinstall the gearbox into a forced system – equipped with an oil pump. The gearbox version with the forced lubrication circulation system is characterized by the fact that changing the direction of rotation does not require the pump system to be reinstalled/reconstructed (oil flow is always in the same direction).

The FP and FKP series gearboxes provide a high level of standardization. This gives us the opportunity to offer possible reinstallation (retrofitting) of an existing solution provided by the customer to change the gear ratio at a much lower cost compared to purchasing a new gearbox.

 

Your advantages:

  • compliance with the RAG N 335 000 standard
  • the highest quality of the product confirmed by high reliability
  • toothed gears made of MQ class material according to ISO 6336-5
  • high-quality cooling systems, ensuring the possibility of continuous operation on the rated parameters of the gearbox
  • rolling bearings from reputable manufacturers only
  • low weight facilitating the transport of the gearbox
  • small dimensions do not limit the width of the personnel walkways
  • each gearbox is tested under rated load to confirm the product quality

Our Gw1000, PD250, W500 cylindrical gearboxes and KB109M, KB250, KB315 angular gearboxes are proven and appreciated by customers all over the world. Powers ranging from 55kW to 500kW and a wide range of gear ratios ensure that they can be used for most drive solutions for armoured conveyors. Gearboxes can be equipped with back stops. Lubrication is provided by a forced oil circulation or splashing systems. Depending on the series of types, gearbox cooling system can be free (convection) or forced with the use of water heat exchangers.

We offer a gearbox of the DPG315 series, which together with the motor is installed inside the belt conveyor pulley  (the so-called drive drum). It is designed on the basis of 2 epicyclic stages, which is a significant advantage in terms of oil distribution, and cooling is provided by efficient water heat exchangers embedded inside the gearbox.
