Warner Mechanical and Electrical Equipment Co., Ltd. Tai'an City (www.tahnjd.com) is located in Tai'an City, Shandong Province, Taian Mountain Avenue, No. A66, Contact: Lee LBY-2 roof separation Monitor (measurement points: 2 points) from roof Monitor also known as tray-layer roof separation indicator is a monitor roof strata movement dedicated monitoring instruments Shandong roof separation instrument, mainly for the use of the tunnel roof bolting and the need to measure the displacement of the face plate from the roof layer instrument manufacturers, engineers and technicians for the mine and monitoring personnel to determine the length of the bolt, 2014 tensile tester latest roof separation counseling, understand the rational use of anchors, economy and the need for scientific evidence. Thus effectively preventing accidents slump roof roof separation instrument to ensure safety in coal mines. The main technical indicators: ① Maximum Scale: 15cm; ② installation point: two little; ③ Resolution: 1mm; ④ maximum distribution distance: 4 m / 8 m. ZKBY-1 type Drift separation instrument ZKBY-1 type instrument is a separation lane to help detect roof strata movement dedicated monitoring instruments. It can display the range of ionospheric conditions within and outside the anchor bolt length with the range of roof strata, respectively. To mine engineering and technical personnel and monitoring personnel to determine the length of the bolt, tensile strength, understand the rational use of anchors, economy and the need for scientific evidence. Thus effectively preventing accidents slump roof to ensure safety in coal mines. There bps roof separation instrument anchors, strand, sleeves, cursors, tighten the screw components.
