This standard is a revision of the 2BJ831 rail-type rock drill. This standard has the following major technical changes compared with ZB.184C15-89: 170 specification has been added to the "rotatable" column of the product series; two indicators, "idling speed" and "torque", have been added to the basic parameters of the standard; the "noise value" has been converted from rated noise to production efficiency numbers, which can replace 2B184016-8. This standard was issued by the National Technical Committee for Standardization of Rock Drilling Machinery and Pneumatic Tools Proposed and attributed to: This standard was drafted by: Shangjing Engineering Machinery. This standard was drafted by: Yisheng Xie, Xu Wenliang, Zhang Hong, the standard was first issued in 1952 and revised for the second time in 1989. 1 Standard
