    QSM-4-22-BKJ is aimed at solving the case of obstructing rescue roads due to the collapse of sealing walls, transformed air gates and rocks that may happen during the rescue in a high-gas inflammable and explosive environment, and sparing valuable time for emergent rescue.

  • qsm-5-15-b-sh waterjet cutting machine

    QSM-5-15-B-SH waterjet cutting machine as hard rock cutting machine is a new type of portable cutting equipment functioning by front-mix abradant water jet flow; it adopts cold cutting technologies.This waterjet cutting machine has passed spark test, static electricity test and temperature test, and met the anti-explosion requirements.Note: QSM-5-15-B-SH waterjet cutting machine is an integral part of the main machine system and provides high-pressure water jet flows for cutting operations; it needs to assist cutters (for example pipe cutter), cutting gun assembly and high/low-pressure hose to complete cutting operations.

  • cutter-bits

    Cutting bit as hard rock cutting machine is a kind of wearable part in roadway excavation machinery, roadheaders. It is the main tool for cutting rock and mineral. Common raw material from the majority of domestic and imported suppliers is : 42Cr, 35CrMnSi and other steel, hardness of up to 40-45HRC, impact toughness of not less than 49J / cm2. Now with the ONE BELT ONE ROAD construction of China along the way, the ROADHEADER machinery has been used more and more in the roadway works apart from the mines due to its better flexibility and lower working cost. Moreover, the cutting-bits at the same time also need to withstand high periodic compressive stress, shear stress and impact load, which requires the cutter body parts to have very good impact resistance and withstand wear and tear.

  • hydraulic-nuts

    The Hydraulic Nut as hard rock cutting machine is a permanent fixture, replacing the conventional nut and retaining the high bolt load and extension in small space envelopes where there may not be sufficient space to use tensioners. The nut can be retrofitted to existing plant and is a simple and accurate solution to mechanical jointing problems.
