Diagram Of Hydraulic Crane. The main pump is able to generate 3 500. A 70 ton hydraulic truck crane uses a 12 7 l diesel engine that generates up to 365 horsepower.
Figure 28 line diagram of simple hydraulic power system. Flow expressed in gallons per minute gpm determines the speed at which a hydraulic cylinder extends or a hydraulic motor turns. This diagram will show the boom length needed to pick up and lift a load.
Flow is produced by the pump.
Pressure expressed in pounds per square inch psi determines the amount of force exerted. A 70 ton hydraulic truck crane uses a 12 7 l diesel engine that generates up to 365 horsepower. Main pump this pump operates the piston rod that raises and lowers the boom as well as the hydraulic telescoping sections that extend the boom. You can operate crane by electric power or water also.
