It is simple, without supporting the roof you just cannot go on. Our proposal: safe and reliable roof supporting products based on proven technologies. This is what we offer: the simple but reliable GSA, GS link bars (forming together with the hydraulic props a flexible roof supporting system) and for longwalls, the powered roof supports SMA range.
