Bolt tension meter in front of the steps to prepare anchor pulling force test have? ? ① According to the test purpose, in the coal mine (tunnel) to develop parts of the rock drill bolt holes. Deep hole depth on the basis of normal minor adjustments to the length of the exposed bolt bigger ensure Rally jack bolt installation; or using a normal hole depth will be tested bolt lengthened, so as to jack bolt tension meter installation provide space. ② according to the normal installation process to install the test bolt, the bolt with mortar smooth mouth to put pressure support plate. ③ determined according to the type and drawing time test purposes bolt. ④ bolt tail plus the plate, put a hollow jack, anchor the outer end of the inner cylinder jack fastened together, and the installation of displacement measuring equipment and instruments. ⑤ by manual hydraulic pump pressurized oil from the oil pressure gauge reading, according to the translation of the piston area anchor withstand the pulling force, depending on the amount required to read from the dial gauge ending displacement bolt, bolt drawing draw force-displacement curves for research and analysis. Prestressed anchor supporting quality Electrical Equipment Co., Ltd. Tai'an City of Warner special production of prestressed detection tensioning equipment, bolting construction, testing equipment: bolt tension meter, anchor dynamometer, Bolt Cutter MJ60-type pneumatic bolt installation machine manufacturers, measuring anchor bolt installation machine where the production, bolt installation machine, bolt preload detector, mine gas trigger, bolt pneumatic wrenches, bolt torque wrench , special elongated sleeve head, the angle detector bolt nut off, bolt load sensor, the load detector anchor bolt installation machine brand pneumatic, bolt torque amplifiers, hydraulic bolt wrench, auxiliary equipment : Mine track gas drilling, pneumatic orbital drilling machines. Bolt preload torque wrench is the main product of Warner Mechanical and Electrical Equipment Co., Ltd. Tai'an City, the following is a brief introduction: "Warner" brand voice alarm bolt torque wrench, extension socket head, adjustable wrench, bolt preload force detector for shotcrete tunnel roadway predetermined torque fastening bolt nut, bolt tension can be detected and used as tools. Separation and collapse accident in shotcrete tunnel, mostly due to the installation of the anchor bolt anchor nut after tightening the fastening indicators did not meet the requirements due; degree of tightening the fastening bolt Luo cap is played a full role in the key in the key, MC3 twist bolt preload torque wrench is an important tool for the completion of this work. MC3 bolt preload torque wrench technical parameters: Torque Detection range: 60-300N.m ,100-500N m; 280-760 Nm; 200-1000 Nm; 700-2000 Nm; 1500-3000N.m; 2500. -4000N.m bolt installation machine, Warner electromechanical pneumatic bolt installation machine, bolt installation machine where the production is provided by Warner electromechanical. Warner Mechanical and Electrical Equipment Co., Ltd. Tai'an City (www.tahnjd.com) in the roof dynamic instrument, mining intrinsically safe pressure detector, under reduced pressure hydraulic support industry self-recording instrument, such as a higher visibility, integrity management, quality of service both welcome to inquire or consult our "Business League call" it!
