双头机械扳手,是我厂拧紧柴油机主轴承盖螺母的专用工具,以前靠人力,用一米长的扳把拧,又费劲,效率又低。革新后,不但大大减轻了劳动强度,而且能保证两螺母受力均匀,提高了装配质量。技术参数同时拧紧的螺母直径:2个 M 22;单头最大扭矩:45公斤-米;工作转速:45转/分; Double-headed mechanical wrench, is our factory tighten the main bearing nut of diesel engine special tools, previously by manpower, with a meter-long pull the handle, and hard, low efficiency. After innovation, not only greatly reduce the labor intensity, but also to ensure that the two nuts evenly stress, improve the assembly quality. Technical parameters At the same time tighten the nut diameter: 2 M 22; single head maximum torque: 45 kg - m; working speed: 45 rev / min;
