JB/T 8296.1-1999 This standard is a revision of JB/T 8296.1-95 "Open wheelsets for narrow gauge vehicles in mines". The bearing models in the basic parameters of open wheelsets were cancelled during the revision, and other major technical contents remained unchanged. This standard specifies the basic parameters, dimensions and technical requirements of open wheelsets for narrow gauge vehicles in mines. This standard is mainly applicable to narrow gauge vehicles used in mines whose wheel treads comply with Type A in GB/T 4695-1984 "Shape and dimensions of wheel treads for narrow gauge vehicles". This standard was first issued as GB 4786.1-84 in November 1984 and was adjusted to JB/T 8296.1-95 in April 1996.
