Silver Spade had only a few hundred feet of coal left to strip. But in April 2006, Silver Spade broke down. Its owner, CONSOL Energy, decided not to repair it. Instead, CONSOL announced that Silver Spade would be sold for scrap.
The grandfather of the hydraulic excavator was no doubt the man who invented the world's first steam shovel. This engineering innovation was developed by American inventor William Otis in the 1830s.
Not a crazy statement, considering the 750 sells for around $500,000. Brennan couldn't even begin to hide his excitement when he jumped into the chair and exclaimed, "This thing is pimp!"
Excavators can reach up to nearly 80 tons; these behemoths fall into the large category.

At this starting point, the machine has 34,210 pounds of lift capacity, so the 3,600-pound pipe on the hook isn't much of a challenge. But, as you ease the load 5 feet off the ground, thus raising the bucket's lift point to 10 feet, capacity diminishes to 29,630 pounds.

A 315 Cat or 160 size excavator would work good for what you want to do. If you were going to be clearing good-sized hardwood stumps you would want a 200 size machine. An excavator works great clearing stumps because after you dig the stump out you can shake it to help get most of the dirt out of it.
The body or cab of a zero swing excavator (sometimes called a zero tail swing excavator) will never go over the tracks of the machine as you rotate it. This means you can operate in tight, enclosed spaces without fear of damaging buildings or the excavator.
Inspection tips: 5 things to look for when buying a used
- Play or movement.
- Cracks, bends and dents.
- Leaks.
- Inaccurate/broken hours meter.
- Scalloping.
Excavators (hydraulic) are heavy construction equipment consisting of a boom, dipper (or stick), bucket and cab on a rotating platform known as the "house". The house sits atop an undercarriage with tracks or wheels. They are a natural progression from the steam shovels and often mistakenly called power shovels.
At a 10-foot radius, lift-over-end capacities of these machines range from 430 to about 10,000 pounds, and lift-over-side capacities go from 210 to 6,700 pounds. 3.
CAT Excavator Average Costs
CAT excavators range in price from about $100,000 to more than $850,000. The price depends on the size of the excavator, its weight, horsepower, and other features. Small CAT excavators range in price from $100,000 to about $230,000.In production since 1998, the 797 series represents
Caterpillar's largest,

Purchased new, a full-sized excavator costs anywhere from $100,000 to $500,000. Small excavators weighing 10 to 15 tons usually cost anywhere from $80,000 to $150,000. Mid-sized excavators weighing 15 to 20 tons (the most common size) generally range in price from $100,000 to $200,000.
CAT Excavator Average Costs
Small CAT excavators range in price from $100,000 to about $230,000. These models weigh about 26,000 to 55,000 pounds and have horsepower ranging from 79 to 188. Medium-sized CAT excavators cost $230,000 to $270,000.Medium-Sized CAT 320 Excavator Cost
Just like the CAT 320, the various medium-sized excavator models by this provider are priced between $230,000 and $270,000. Such models weigh between 65,000 and 80,000 pounds and have a power rating of 204 to 268 horsepower.That wide range, however, can be narrowed as soon as you know what type of excavator you want to rent. Mini-excavators usually rent between $200 and $500 a day, while heavy-duty excavators that are meant for mining work can rent for up to $3000 a day. Mid-range models go for $400 to $1200 a day.

Small CAT excavators range in price from $100,000 to about $230,000. These models weigh about 26,000 to 55,000 pounds and have horsepower ranging from 79 to 188. Medium-sized CAT excavators cost $230,000 to $270,000.So the 797 carries a nominal load rating of 360 tons, but it's capable of accepting 400 tons. And 400 tons is roughly the weight of 120 Ford Excursions. When shovels grow again, so will the trucks. Beyond the 797's cost of $3.4 million, mine operators need to make serious infrastructure changes to accommodate it.

The main difference between the two machines is size — excavators are larger and heavier, while backhoes are slightly smaller. The excavator is typically a better fit for demolition projects, mining, driving piles, drilling shafts for rock blasting, and overall large-scale industrial projects.
Backhoe loaders are one of the most versatile pieces of equipment you can rent. As an excellent multipurpose machine, a backhoe loader can tackle a variety of jobs in construction, agriculture, and landscaping. The flexible rental periods let you complete your job in time at an affordable price.
So sit back and enjoy our list of the best backhoe loaders.

Horsepower. Backhoes fall into two unofficial categories, those that run 14 to 15 feet and offer horsepower that ranges from 68 to 107 hp, and those that are 15 feet in length (or more) and provide output of 127 hp or more.
The smallest machines capable of digging just six feet deep can be purchased for $12,000 to $20,000. Backhoe loaders with a dig depth of 9 to 10 feet usually cost $25,000 to $35,000. Machines with a 14-foot dig depth - the industry standard - and horsepower between 70 and 90 cost anywhere from $50,000 to $90,000.
JCB backhoe loaders are versatile machines that combine excellent trenching, excavating, loading, lifting and material handling capabilities with the benefits of a single machine that is easy to maintain and simple to operate.
A backhoe, also known a rear actor or back actor, is a section of excavating equipment or digger consisting of a digging bucket on the end of a two-part articulated arm. They are typically mounted on the back of a tractor or front loader. Modern backhoes are powered by hydraulics.
