Obsolete and outdated equipment is gradually being replaced. As far as the Jinan City Construction Management Bureau system is concerned, in the 1980s, old-fashioned winches that were used in the past were eliminated and the mining winch (hereinafter called winch) produced in Shanghai, Xuzhou, etc. was used.
