摘要： A longwall mining shield base lift. The base lift includes a hydraulic cylinder having an apparatus for coupling the hydraulic cylinder to the longwall mining shield, a cylinder rod having a first end extending into the hydraulic cylinder and a second end for extending toward ground beneath the longwall mining shield, the second end being threaded axially, and a threaded wear pad threaded onto the cylinder rod. The wear pad includes a plurality of spanner holes for rotating the wear pad with a lever, at least one threaded retaining hole extending axially through the wear pad, and a retaining bolt threaded through the retaining hole until it contacts the cylinder rod.

摘要： Apparatuses and methods for a trailer that hangs when not in use and on which material may be transported. The apparatuses include a trailer having a single wheel bracket attached to at least one wheel and a trailer body. The trailer body has a first end and a second end and is attached to the single wheel bracket near the first end. The trailer body has a first coupler at the first end and a second coupler at the second end, the first coupler to attach the trailer to a second trailer and the second coupler to attach the trailer to a third trailer such that the trailer hangs by only the single wheel bracket from the first rolling surface of the beam-type rail when the trailer is not attached to the third trailer.
