03.02.2016Hydraulic props were introduced in the 1940s, followed by the Eastern European concept of a shield support comprised of a rigid, half-arch, frame to protect the face from goaf flushing. These early support systems provided the basis for the first longwall powered supports, so-called because they were connected to a hydraulic power supply and capable of self
