Scope

NB/T 11530-2024 is the English-translated version of 矿用液压混凝土喷射机械手通用技术条件.

NB/T 11530-2024 is the general specification for hydraulic concrete spraying manipulators used in coal mines, the mechanisms on shotcrete machines that move the spray gun forward and back, left and right, up and down and change its angle.

It lays down model designation, requirements, test methods, inspection rules, and marking, packaging, transportation and storage, and defines terms such as spray gun and maximum spraying width.

The references indicate the checks involved: noise by sound power level, friction spark safety of metals, flame retardancy and antistatic properties of polymer parts, hoses, lighting and signal lamps, and hydraulic components and systems for coal mining machinery. Issued on 24 May 2024, it has applied since 24 November 2024.
