The hydraulic crane functions on the simple principle of hydraulics – the transmission of force by fluid. Most hydraulic cranes use an incompressible fluid (a fluid that is as dense as it can be), most commonly oil. In a most basic hydraulic system, a piston pushes the liquid down, and the liquid transmits this force to another piston, which is driven up. There is a hydraulic pump which is responsible for creating pressure to move the pistons. Most hydraulic cranes use a two-gear pump, so that when the pressure needs to be bigger for more power, the operator pushes a throttle to run the pump at a greater speed.
It is fairly easy to rent a hydraulic crane for your personal needs. Modern mobile hydraulic cranes can lift and move hundreds of tons to a height of over forty stories. There are lots of companies dealing in crane rentals which offer both hydraulic crane rentals and hydraulic truck cranes. When renting a hydraulic crane many companies will also offer the service of a crane operator, seeing as operating a crane without qualifications can result in loss or injury.
