JAE42 Continuous Miner - Wildcat

In 2014, JAE was approached to find a solution to reduce the running cost of continuous miners, in particular, the usage of torque shafts, clutches and planetary assemblies.  After extensive testing and discussion with customers, JAE was able to offer a new solution, designed in 2015: a new continuous miner customised for hard cutting conditions.  The Wildcat was designed and built from the ground up.  The prototype was displayed at the end of 2016 at Electra Mining. In 2017, the JAE42 Wildcat went into operation for a 6 month trial period to prove the design philosophy and cutting system was sound. After the successful trial, the Wildcat was adapted for a higher seam and the JAE42H was sold in 2019 to a mining customer.  Based on the success of the JAE42 Wildcat, the mining customer has since ordered of a smaller continuous miner namely the JAE38 Wildcub, which will be delivered in January 2021.

In addition, the customised JAE42A has recently been supplied for a punch-mining solution in Australia.
