The Fundamentals Of Hydraulic Cranes

 

Cranes play an important role in today’s society. Hydraulic cranes give power and mobility that is unparalleled.

Hydraulics Explained

Hydraulics uses force applied at one location to transfer force to another area using an incompressible liquid such as oil. Hydraulic systems are almost always created to increase force, so the amount of force applied to the end location is higher than the force needed to be generated begin the system. A common hydraulic example is in a car?s brake system. When you lower the brake pedal, a pump moves fluid through the line, which squeezes the brake pads against the wheels of the car. Hydraulics are also commonly used in lifting.

Hydraulic Crane Trucks

Crane trucks take advantage of the principle of hydraulics to lift and move a many heavy loads. The trucks differvary in size and specialty. Some trucks are more suited for the heaviest lifting, others for jobs that need a great deal of height, and some even have all-terrain capabilities. The trucks are named according to the amount of weight they are able to lift, for example, a 20 ton crane is able to lift 20 tons.

Boom

A boom is an extending arm that extends for a longer reach, or to raise the pulley. A boom is often separated into sections and a hydraulic pump will fill each section with fluid, which causes the boom arm to become firm. Fire ladder trucks, crane trucks, and some utility trucks have a boom arm. Some boom arms are long enough to require a jib, a latticework structure that maintains support and length to the boom arm.

Rotex Gear

While the boom arm is used for raising and lowering the crane, the rotex gear, generally found underneath the cab, moves the crane from side to side. The rotex gear appears like a giant clock gear, and works in much the same way to operate the crane from side to side efficiently.

Outriggers

Tires alone will not provide the support necessary to stabilize the crane truck. Without more support, the trucks would tip or just be unable to perform. Outriggers give the crane truck more/additional strength by extending several feet in both directions from the truck. Hydraulics are used in the outrigger system also, the whole truck is lifted and all weight is moved to the legs of the outriggers. Counterweights are also used to also balance the truck during the lift.

Now when you see a crane working in the future, you will have a better appreciation of the technology that make a crane work and how important they are to our cities and lifestyle.
