FOREWORD

• The purpose of this manual is to provide information concerning the electrical maintenance of the 45-R and 47-R rotary blast hole drills. The drill consists of three major units; the lower works, the mainframe and the mast.
• The lower works provides a foundation for the mainframe and contains a portion of the equipment necessary to propel the drill. The mainframe includes the hydraulic, main air and auxiliary air systems, the hoist-propel transmission and the machinery house.
• The machinery house encloses the majority of the mechanical equipment necessary for the main and auxiliary air systems, the hydraulic systems and electrical control systems.
• The machinery house is pressurized with filtered air to minimize dirt and heat build-up. The operator’s cab, mounted to the mainframe, provides the operator’s station, and encloses the majority ofthe controls necessary to operate the drill. This manual consists of three chapters, each divided into sections. A table of contents is located in the front of the manual.
