1. A crane control system for controlling and/or for the hydraulic supply of hydraulic loads of a crane comprising: at least one first pump and at least one second pump, at least one first split control block and at least one second split control block, by which at least one hydraulic load of the crane is respectively supplied with hydraulic medium, wherein the first pump is connected to the first split control block and is driven by a first hydraulic pressure, and wherein the second pump is connected to the second split control block and is driven by a second hydraulic pressure, whereinduring certain engine operating conditions, the first or the second hydraulic pressure is equalized by a crane controller, wherein a respective lower hydraulic pressure is equalized to a higher hydraulic pressure and thereby increased. 2. The crane control system according to claim 1, wherein between the first split control block and the second split control block at least one valve is arranged by which the first split control block and the second split control block are hydraulically connected and disconnected, wherein at least one switch is provided by which the valve is actuated. 3. The crane control system according to claim 2, wherein at least one third pump and at least one third split control block is provided by which at least one hydraulic load of the crane is supplied with hydraulic medium, wherein the third pump is connected to the third split control block and is driven by a third hydraulic pressure. 4. The crane control system according to claim 3, wherein between the third split control block and the first split control block or the second split control block, at least one second valve is arranged, by which its third split control block is hydraulically connected and disconnected to the first split control block or the second split control block. 5. The crane control system according to claim 4, wherein at least one additional switch is provided by which the second valve is actuated. 6. The crane control system according to claim 3, wherein at least one crane controller is provided by which at least one first hydraulic pressure and at least one second hydraulic pressure is adjusted, wherein it is furthermore provided that the third hydraulic pressure is adjusted by the crane controller. 7. The crane control system according to claim 6, further comprising a revolving superstructure whose rotation is accomplished by the third pump. 8. The crane control system according to claim 1, wherein at least one hydraulic load of the crane is a crane actuator. 9. The crane control system according to claim 8, wherein the crane actuator is one or more of a rotating mechanism, a luffing cylinder, a winch, a telescoping drive mechanism, and a caterpillar drive. 10. The crane control system according to claim 1, further comprising an economy switch, wherein the crane controller does not equalize the first or the second hydraulic pressure when the economy switch is activated. 11. A crane, comprising: a hydraulic supply of hydraulic loads;a control system for controlling the hydraulic supply including at least one first pump and at least one second pump, at least one first split control block and at least one second split control block, by which at least one hydraulic load of the crane is supplied with hydraulic medium, wherein the first pump is connected to the first split control block and is driven by a first hydraulic pressure, and wherein the second pump is connected to the second split control block and is driven by a second hydraulic pressure, whereinduring certain engine operating conditions, the first or the second hydraulic pressure is equalized by a crane controller, wherein a respective lower hydraulic pressure is equalized to a higher hydraulic pressure and thereby increased. 12. The crane according to claim 11, wherein between the first split control block and the second split control block at least one valve is arranged by which the first split control block and the second split control block are hydraulically connected and disconnected. 13. The crane according to claim 12, wherein the crane controller is provided by which at least one first hydraulic pressure and at least one second hydraulic pressure are adjusted. 14. The crane according to claim 12, wherein if the crane controller determines that a load requires a higher volumetric flow rate than the first and second pumps are able to produce, then the crane controller first starts one of the first and second pumps that already has lower hydraulic pressure to match one pump's pressure to another of the first and second pumps and then opens the valve. 15. The crane according to claim 12 wherein the hydraulic load of the crane includes a crane actuator. 16. The crane according to claim 15, wherein the crane actuator is a rotating mechanism. 17. The crane according to claim 15, wherein the crane actuator is a luffing cylinder. 18. The crane according to claim 15, wherein the crane actuator is a winch. 19. The crane according to claim 15, wherein the crane actuator is a telescoping drive mechanism. 20. The crane according to claim 15, wherein the crane actuator is a caterpillar drive.
