Крепь относится к горной промышленности, в частности к щитовым крепям для отработки крутых и наклонных пластов столбами по падению. Щитовая механизированная крепь для пластов крутонаклонного залегания состоит из отдельных секций, соединенных в единую конструкцию. Каждая секция состоит из основания, перекрытия, которое задней частью свободно опирается на секторную опору основания, а передней шарнирно связано с ним через стойку и снабжено домкратами передвижки. Щитовое перекрытие выполнено из продольных поперечных несущих балок и ограждения в виде рамы и гибкого перекрытия, уложенных на поперечные балки секции крепи, при этом продольные балки выполнены телескопическими, а поперечные прикреплены к ним посредством быстроразъемных эксцентриковых захватов. Передняя поперечная балка выполнена клинообразной формы, образуя скалывающий козырек.The support refers to the mining industry, in particular, to shield fixings for working steep and inclined seams with pillars in the fall. Shield mechanized lining for steeply inclined seams consists of separate sections, connected in a single structure. Each section consists of a base, an overlap, which, with its rear part, freely rests on the sector support of the base, and the front part is hinged to it through a rack and is equipped with shifting jacks. Shield overlap is made of longitudinal transverse carrier beams and fencing in the form of a frame and flexible overlap, laid on the transverse beams of the lining section, with the longitudinal beams made telescopic, and transverse attached to them by means of quick-release eccentric grippers. The front transverse beam is made wedge-shaped, forming a chipping visor.
