They are equipped with wheels and can turn in their own tracks, making them extremely valuable for applications that require a compact, agile loader. They have light weight and so, they can be towed behind a pickup truck. The skid steel loader has four wheels and its characteristic is that the left-side drive wheels are independent of the right-side drive wheels. This way, wheel speed and direction of rotation of the wheels will determine the direction the machine will turn. The skid steel loaders have a simple operating system. Inside the cabin there are two joysticks: a left hand joystick and a right hand joystick. The left hand one is made for controlling the direction. The right hand one is for controlling the loader arms and bucket. By pulling the joystick back, the arms of the machine will raise; by pushing the joystick forward, the arms will be lowered. In order to tilt the bucket up the joystick must be moved to the left. By moving it to the right the bucket will dump. All the system is powered by hydraulic pumps, meaning that there is no mechanical transmission.



The Skid steel loader is suitable for digging and moving landscaping and other building materials. Due to its numerous tools it can also grade, jackhammer cement and load trucks. Some of the special tools of the skid steer loaders are: a dirt bucket, utility grapple bucket, pallet forks, utility fork, angle blade, auger, broom, cold planer, hydraulic hammer, landscape rake and tillers, material handling arm, stump grinder trencher and a vibratory compactor. These tools make skid steel loaders quite useful because there will not be necessary 10 machines any more to complete all these functions.

Another useful machine in the construction field is the backhoes. They are generally used for many different jobs and can replace many other types of heavy equipment at the construction site.

They are designed in a unique way; they have tools sticking out from every way of the machine. The backhoes can be considered to have three pieces of construction equipment combined into one unit: a tractor, a loader and a classical backhoe. Because the backhoes can use all these three functions at a construction site they are considered to be quite valuable and replace other machines.

The backhoe's core structure is the tractor. Its design allows the machine to move easily over different type of rough terrain. It is equipped with a turbocharged diesel engine, with tires and a cabin for the pilot.

The loader is another part of the backhoe. It is attached in the front, while the backhoe is situated in the back. The loader is used as a spoon that picks up and carries a lot of loose material. It can also be used for smoothing things over, or for pushing dirt.

The backhoe loader also has a backhoe in the back of the tractor. Its function is to dig earth, or to lift heavy loads and then drop them in a pile at the side of the hole. All kinds of holes can be digged with a backhoe but most of all is suitable for ditches. In order not to fall inside the hole, the backhoes are equipped with stabilizer legs.

The backhoes are used mostly for digging ditches with the backhoe, and then for carrying out the dirt with the loader. After the work is done in that are, the loader will fill back the ditch with the extracted dirt.

These machines, the skid steer loader and the backhoe are very useful nowadays because they are very efficient and they save a lot of time because the operator doesn't have to switch between two different pieces of equipment any more.
