DRAGLINES

CONTENTS DRAGLINES

INTRODUCTION Draglines are an important excavating tool used inmany surface mining operations worldwide. These highly pro- ductive machines operate 24 hours a day, seven days a week and are able to reach depths of 79.8 m (262 ft) with capacities up to 116.2 m3 (152 yd3). Offering the lowest material removal cost per tonne (ton) and an average operating life of 40 years, draglines are the most produc- tive and versatile machine in the industry. Caterpillar offers an extensive variety of dragline specifications and on-staff application engineers who will help determine the solution that best addresses specific needs. With over 100 years of dragline experience and the largest operating fleet of draglines with buckets of 40 m3 (52.3 yd3) and above, coupled with an active installed base of over 300 machines, Cat draglines are the most effi- cient and proven overburden removal solution. SAFETY AND SERVICEABILITY Safety plays an integral role in everything we do at Caterpillar, from our factory floors to our service centers to our clients’ mine sites. Caterpillar’s commitment to safety is apparent in our product designs, which undergo risk assessments and are designed to meet strict codes and regulations. Stairways, walkways, platforms and access points are incorporated throughout Cat ® draglines to ensure safe and convenient access for maintenance per- sonnel. With safety and serviceability enhancing features incorporated into the operator cab, structures, surfaces and electrical equipment, among others, Cat draglines were designed with safety in mind.
