"Regolith" is the industry term for loose mineral material covering bedrock.Įxcavators become more technically advanced each year. The Regolith Advanced Surface Systems Operations Robot (RASSOR) Excavator is a mini-mover that works in low-gravity environments such as those on the Moon, Mars, asteroids and comets. Some excavators are designed with the future in mind. The Cat 300.9D has a 13 horsepower engine running its tracks, bucket and blade. Don’t think that small size means low power, though. It can sneak through a doorway to take on interior demolition challenges. It measures 28 inches wide and has a retractable undercarriage. On the small-scale end, there's the Cat 300.9D. The machine is big enough to see in satellite photos. It has a bucket wheel feature that handles 8.5 million cubic feet per working day. It’s the Bagger 293 mining machine, which tips the scale at 14,200 tons. The world’s largest land vehicle title also goes to an excavator. Its twin 4,500 horsepower engines drive a 65-yard bucket that moves 9,000 tons of material per hour. The behemoth Bucyrus is 32 feet tall, 24 feet wide and weighs 980 tons. The world record for the largest excavator goes to the Bucyrus RH400. Over the years, some excavators have set world records. It wasn’t long before Cat engineers put tracks under their hydraulic excavators, revolutionizing the earthmoving world. Cat® machines were the first to use steel-linked tracks, which propelled their first bulldozers. The Caterpillar Tractor Company entered the heavy equipment scene in 1925. It was the first truly hydraulic excavator without chains or cables. By 1897, the Kilgore Machine Company introduced the Direct Acting Excavator. featured steam-driven cylinders moving cables. Hydraulic excavators, which also use steam power, date to 1882. A team of men with picks and shovels could only dig 12. It could move 300 yards of material per day. By the mid-1800s, his steam shovel invention was the backbone of railway construction. William Otis assembled a highly functional system of gears, chains, pulleys and cables to excavate dry earth. Mechanized excavators have been around for over two hundred years. If you're considering renting or using an excavator, get the full story on these dependable digging tools. Excavators also have complex parts and a surprising array of attachments available. You’ll find several the different types of excavators available, such as mini-excavators, backhoe excavators, extended-reach excavators and even excavators built to use suction rather than teeth. It’s easy to get confused when researching excavators. There’s no such thing as a one-size-fits-all application when it comes to excavators. It’s additional questions like what excavator types, what sizes, what power and what attachments you’ll find around excavation jobs. It’s not just a question of using an excavator to dig, load or spread. If there’s material to move, no doubt you’ll find an excavator nearby. They’re also invaluable for general construction and utility work, demolition and scrap businesses, quarry and aggregate operations as well as handling waste and recycling products. Excavators are indispensable equipment pieces in the earthmoving business.
