Hydraulically operated lining jack system with servicing platforms is meant for mechanization of operations, connected with installation of arched lining from the П110 roadheader in working. Lining jack system is made as separate module, which can be installed to the roadheader with small labor costs (or dismantled, if necessary).
Hydraulic equipment of the lining jack system is powered by the hydraulic system of the roadheader. Servicing platforms, “arm” for lifting the upper part of fasteners, hydraulic block of lining jack system control, lines of working fluid supply to hydraulic cylinders are installed in module. If necessary, technical parameters of the lining jack system can be adapted to the mine working section.
