Cat® 8000 Dragline Range (Imperial Weights/Measurements)

Product catalog summary

Specifications:
The Cat® 8000 Dragline Range features two typical boom lengths of 250 ft and 275 ft. The net weight with bucket and ballast is approximately 3,200,000 lbs for the 250 ft boom and 3,250,000 lbs for the 275 ft boom. The working weight with the bucket is approximately 3,860,000 lbs and 3,950,000 lbs, respectively. Ballast weight provided by the customer ranges from 660,000 lbs to 700,000 lbs. Variations in ballast requirements and net weight depend on boom length and rated suspension load, with a variance of ±5%.

Performance Parameters:
For a 250 ft boom, the operating boom angle is 32°, with a suspension load of 210,000 lbs. The boom point height is 146 ft, dumping height is 96 ft, and digging depth is 145 ft. For a 275 ft boom, the operating boom angle is 38°, with a suspension load of 207,000 lbs. The boom point height is 183 ft, dumping height is 134 ft, and digging depth is 128 ft. Both configurations use drag and hoist drums with a rope diameter of 2.75 inches.

Dimensions and Working Ranges:
The clearance radius is 53 ft 6 in, and the boom foot radius is 20 ft 3 in. The boom foot height is 13 ft 6 in. The electrical system includes two hoist motors and two drag motors, each with 1,650 hp, two swing motors with 640 hp, and one walking motor with 1,650 hp.

Base and Frame:
The base has an outside diameter of 50 ft, with a bearing area of 1,963 ft². The circle rail diameter is 50 ft, and the swing gear pitch diameter is 42 ft 6 in. The walking mounting features a shoe width and length of 9 ft x 48 ft, with a combined bearing area of 864 ft². The overall width over shoes is 71 ft, and the length of step is approximately 7 ft, with a walking speed of approximately 0.15 mph. The revolving frame has an upper machinery frame width x length of 43 ft x 75 ft, and a girder depth of 6 ft 8 in.
