Are draglines still used?
Giant draglines have long since been made obsolete, but dragline excavators are still very much in use. The largest available dragline on the market today is Joy Global’s P&H 9020XPC.
How much is a dragline worth?
A large dragline system used in the open pit mining industry costs approximately US$50–100 million.
Where is the biggest dragline in the world?
The Cat 8750 is equipped with the world’s longest boom measuring up to 132.5m (435ft) and has a suspended load capacity of up to 383,286kg. The dragline is AC-powered and has been operational at TransAlta’s Highvale coal mine in Alberta, Canada, since 2010.

Where is Big Muskie now?
Miners Memorial Park
Shut down in 1991, “Big Muskie” was finally dismantled for scrap in 1999. The only component saved was the bucket, which was later incorporated into a display about the machine and surface mining and reclamation in Miners Memorial Park in McConnelsville, Ohio.

How big was the bucket on Big Muskie?
220-cubic-yard
Big Muskie was the largest dragline ever built. The 220-cubic-yard, 240-ton bucket is a true engineering marvel. Due to the massive size of the machine, Big Muskie had to be built on site. Starting in 1967, more than 300 railcars and 250 trucks hauled the necessary pieces to Muskingum Mine.
Is the Big Muskie bucket still there?
There were efforts to have Big Muskie preserved and relocated, but the money could not be raised and in May 1999 Big Muskie was disassembled and recycled. All that remains is the bucket. Today visitors can climb inside the bucket and imagine what it took to make such an enormous thing move.
How fast does a dragline walk?
Draglines are not designed to cover such a great distance, but are fitted with a propulsion mechanism that allows them to ‘walk’ slowly. So slowly, however, that travelling to the new site at a speed of just 0.1 to 0.2 kilometers per hour would mean the dragline would be out of operation for months.
