Features: This book focuses on enhancing the safety technology training of special operation personnel in mines, based on the requirements for main hoist operators outlined in the "Safety Operation Qualification Assessment Standards for Mine Special Operation Personnel." It comprehensively introduces the fundamental theories, safe operation, and maintenance management techniques of main hoists. The aim is to improve the safety awareness, sense of responsibility, practical operation skills, and accident-handling capabilities of main hoist operators, thereby the quality of special operation personnel in mines. The book covers the basic principles and structures of various main hoists, including single-rope winding hoists, multi-rope friction hoists, and explosion-proof hydraulic winches. It also discusses the motor rotor circuit resistance speed regulation system, G-M DC speed regulation system, V-M DC reversible speed regulation system, and AC motor AC-AC frequency conversion speed regulation system of hoisting electromotors. Additionally, the book includes operational methods, management, maintenance, and repair techniques for main hoists, case studies and preventive measures for accidents, and basic knowledge of mine safety. This book primarily serves as a training textbook for the safety operation qualification of main hoist operators and can also be referenced by maintenance, management, and related engineering technicians.
