Bucket-wheel excavators were first used in the late 1800’s to excavate ditches for hydroelectric power plants. These early models were powered by steam or water pressure from behind the engine. This type of excavator had a bucket on the front and a roller with sprockets on each end. There was a drum under the bucket that turned to move the excavator forward. The bucket used was typically either made out of steel or rubber.
Bucket-wheel excavators are still used today in excavation sites for mining, construction, and other commercial activities. This vehicle is commonly set up for a continuous operation to dig over the ground quickly with a large wheeled bucket of smaller buckets. A conveyor belt then lifts the debris to be transported away. The conveyor system is controlled through hydraulic lines and can sense any changing ground conditions such as vibrations or weight. The crawler is under the wheel that moves the bucket along and accesses the desired area.
An alternative to bucket wheel excavators is the construction car and wheelbarrow combo. These equipment combinations consist of a front-wheel digging truck and a front-end loader. The vehicle usually has a bucket attached to the front of the cab and a crane and boom that allows it to dig shallow wells, install fencing, and remove solid materials such as timber. With the addition of a wheelbarrow, the car can be used to scoop up pans, soil, and other objects to make masonry work. It also has sufficient lifting capacity to haul heavy dump trucks.
Uses of Wheel Excavators
The use of wheel excavators is more versatile than other types of construction equipment. The construction worker does not have to stop work to check on the status of the machine periodically. There are no constraints to the distance the machine can be operated from the job site since it can easily go to places that require excavation, such as an open pit. There are also no limits to how deep the digger can go, which makes it a great option for jobs that need to extend the depth of a trench or dune.
For companies that cannot afford to own one of these machines, there are several options available for rental. Many companies have a wheel excavator rentals division in their facilities, where a rental will be made available on a temporary basis, usually, until the job is completed. This can be an attractive option for companies that need to get the job done quickly but cannot afford to buy a machine outright. On a long-term basis, many rental companies will make all equipment and components available to their customers, allowing them to continue with their production at their current job site.
When it comes to buying a used wheel excavator, there are several factors that must be considered before making a purchase. Because of their size and weight, most wheel excavators have a limited practical lifespan, depending on the conditions in which they will be used. They are most useful when performing short tasks that do not take a great deal of time to complete. This includes digging up the earth on a small scale, such as setting up a tent, and for tasks such as clearing debris from a sidewalk. Because these machines are not built to handle large loads, it is important to hire a company that can provide maintenance and service for a reasonable price.
