What are the advantages of a hydraulic crane?
From powering large industrial machinery to small water guns, hydraulics operate by adding pressure to a liquid to generate force. For the water gun, the liquid is forced out by squeezing the trigger. In heavy machinery, the liquid - usually oil - is contained and under constant pressure during use.
That constant pressure allows cranes to lift and move an incredible amount of weight. Hydraulic systems allow cranes to be lightweight and easy to operate. Hydraulics are used in a wide variety of machinery outside of cranes, including garbage trucks, bulldozers, and excavators.
How does a hydraulic crane work?
By forcing oil through a system of pistons, hoses, and pumps, hydraulic cranes are able to produce an immense amount of power. The larger the force, the larger the lifting capacity. Once the system has been fully pressurized, the pistons move the oil back and forth to generate the power.
The system is completely sealed, helping maintain the pressure. If there are leaks in the system, the pressure is lost, and performance is affected. There are some planned leaks to allow the oil to keep the moving parts lubricated, although it is still contained within the system.
Compact, easy to use
An incredible amount of power is generated through hydraulics, allowing hydraulic truck cranes to operate more nimbly than conventional cranes. Eliminating the need for cumbersome pulleys and gears, hydraulic cranes are also easier to maintain because of fewer moving parts. Because the system is under constant pressure, the controls are more responsive as well.
Invaluable for its combination of efficiency and power, hydraulic cranes are ideal for construction sites, manufacturing facilities, and other industrial uses. The versatility of these cranes is invaluable at work sites where continual heavy lifting is required. Have an upcoming job where having a mobile hydraulic crane could be useful?
