WILDCAT JAE42 CONTINUOUS MINER
Local Engineering
JA Engineering is proud to be a mining supplier which engineers and manufactures world class mining technology products.
Criteria for the new Wildcat CM:
- Ergonomic considerations
- Safety and best operating practices considered at the start to identify and mitigate safety risks.
- Some existing continuous miner limitations have been reduced.
- Increased reliability / life of components.
- Cutter drive engineered for improved control and to reduce stalling tendency.
- Some basic machine mining specifications can be altered by the changing of some components.
- Advanced technologies have been used in the manufacture.
- Newer advanced technologies relating to personnel proximity location are also being implemented.
- A lower risk approach has been used aiming for Zero Harm.
Specification of Machine
The Wildcat JAE42 CM is a remote controlled mid-high seam double pass continuous miner. The machine is capable of transforming a high installed cutting power through the machine weight into real production and cutting performance. The Wildcat JAE42 CM is engineered to be used in a room and pillar coal mining operation, where a high cutting force is required.
