FOREWORD

• The purpose of this manual is to provide information concerning the mechanical maintenance of the 1370W Walking Dragline.
• The Model 1370W consists of three major units, the lower works, the rotating deck and the front end equipment. The lower works provides a foundation for the revolving frame and contains the base, swing rack and roller circle. The rotating deck includes the revolving frame and machinery house.
• The machinery house encloses all of the hoist, swing, drag and propel machinery, and the electrical systems required to control machine functions. It also contains an air filtration system to minimize heat and dirt build-up in the machinery house.
• An elevated cab mounted on the house provides the machinery operator’s station. The cab contains all machine operating controls. The front end equipment is comprised of the A-frame, fairlead, mast, boom, running ropes, boom structural strands, and dragline bucket.
• This manual consists of four chapters, each divided into sections. A table of contents is located in the front of the manual.
