However, these machines were built to last indefinitely under continuous heavy use and strip mining is now less popular, so there is little demand for new machines. [2] In 1995, it was itself superseded by the slightly heavier Bagger 293 (14,200 tons). The bucket-wheel itself can be over 21 m (70 ft) in diameter with as many as 20 buckets, each of which can hold over 15 m3 (20 cu yd) of material. In early cell-type bucket wheels, the material was transferred through a chute leading from each bucket, while newer cell-less and semi-cell designs use a stationary chute through which all of the buckets discharge.[4]. The bucket wheel from which the machines get their name is a large, round wheel with a configuration of scoops which is fixed to a boom and is capable of rotating. Mobile Aggregate Processing Plant with boom retracted measures over 8” high, 34” long and 8” wide, and … A bucket wheel excavator (BWE) consists of a superstructure to which several more components are fixed.

Whether you are for group or individual sourcing, we will provide you with the latest technology and the comprehensive data of Chinese suppliers like Bucket Wheel Excavator factory list to enhance your sourcing performance in the business line of manufacturing & processing machinery. They are continuous digging machines in large-scale open cast mining operations. The overburden is then delivered to the discharge boom, which transfers the cut earth to another machine for transfer to a spreader. [4] The BWEs used in the United States tend to be smaller than those constructed in Germany.[5]. On older models these would be rails for the machine to travel along, but newer BWEs are frequently equipped with crawlers, which grant them increased flexibility of motion. While the overall concepts that go into a BWE have not changed much, their size has grown drast… All of these … It has a minimum turning radius of approximately 50 metres, and can climb a maximum gradient of 1:18 (5° incline). Few companies are willing or able to manufacture the massive, expensive gears required for BWEs. This highly detailed 2-in-1 model has been designed to provide an … Bucket Wheel Excavator measures over 16” high, 28” long and 11” wide. Bucket wheel reclaimers are used to pick up material that has been positioned by a stacker for transport to a processing plant. [4] The overburden can also be transferred directly to a cross-pit Spreader, which reaches across the pit and scatters overburden at the dumping ground. BWEs are used for continuous overburden removal in surface mining applications. What sets BWEs apart from other large-scale mining equipment is their large wheel with a continuous pattern of buckets to scoop material as the wheel turns.. They rank among the largest vehicles (land or sea) ever produced, and the largest of the bucket-wheel excavators (the 14,200 ton Bagger 293) still holds the Guinness World Record for the heaviest land-based vehicle ever constructed. Moving Bagger 288 in one piece was more economical than disassembling the excavator and moving it piece by piece. Bucket-Wheel Excavators (BWEs) are continuous mining machines for overburden (semi-hard material such as clay, sand, gravel, marl, etc. The Bucket-wheel excavator is a heavy-duty excavator, primarily used for large-scale surface mining, which works by scooping out massive amounts of earth with its giant wheel, rimmed with excavator buckets. In shipyards, bucket wheels are used for the continuous loading and unloading of ships, where they pick up material from the yard for transfer to the delivery system. The large surface area of the tracks means the ground pressure of the Bagger 288 is very small (1.71 bar or 24.8 psi); this allows the excavator to travel over gravel, earth and even grass without leaving a significant track. Just lay out your lift, curl in the bucket … Because of the great demand for lignite, lignite mining has also been one of the areas of greatest development for BWEs. To allow it to complete its duties, the superstructure of a BWE is capable of rotating about a vertical axis (slewing). Cat® wheeled excavators have the mobility, speed, power, and reliability to be the most versatile machine in your fleet. Chironis, N. (1984).

The construction and removal of the heaps are an obvious application of stacking and reclaiming technology. This may be a fixed belt conveyor system or a mobile conveyor with crawlers similar to those found on the BWE. By slewing, the excavator can reach through a horizontal range. By February 2001, the excavator had completely exposed the coal source at the Tagebau Hambach mine and was no longer needed there. They use their cutting wheels to strip away a section of earth (the working block) dictated by the size of the excavator. Through hoisting, the working block can include area both above and below the level of the machine (the bench level).
