Why is my HYVA Amco Veba 812 crane slow?
The slow movement of your HYVA Construction Equipment crane could be due to a crushed suction pipe. Replace the suction pipe to resolve this. Alternatively, it might be caused by air being drawn in. Check the tightness of the fittings on the suction pipe.
What to do if HYVA Amco Veba 812 Construction Equipment crane doesn't complete movements?
If your HYVA Construction Equipment crane isn't completing its movements, it might be due to a low oil level. Restore the oil level in the tank.
Why does HYVA Construction Equipment crane performance decrease and oil temperature increase?
The decrease in performance and increase in oil temperature in your HYVA Construction Equipment crane, requiring higher engine RPM to lift the specified load, is likely due to pump wear. Check the pressure on the pump outlet. If needed, have it replaced at an authorized service center.
What to do if HYVA Amco Veba 812 crane vibrates with hot oil during all movements?
If your HYVA Construction Equipment crane vibrates with hot oil during all movements, it could be due to a lack of oil in the tank. Add hydraulic oil to resolve this. It may also be caused by air in the hydraulic circuit. Operate the controls to bring the cylinders to the end of their stroke in both directions repeatedly.
What to do if HYVA Amco Veba 812 Construction Equipment crane doesn't lift load with all movements?
If your HYVA Construction Equipment crane doesn't lift the load with all movements, it could be due to oil leaks in the hydraulic system. Alternatively, it could be caused by wear, poor sealing, or internal dirt in the general overpressure valve. In both cases, it is suggested to visit an authorized service center.
What to do if HYVA Amco Veba 812 Construction Equipment crane lifts load but cannot sustain it?
If your HYVA Construction Equipment crane lifts the load but cannot sustain it, it might be because the boom valves are out of calibration. Calibrate the valves. Alternatively, it could be due to worn cylinder seals. Replace the seals.
What to do if HYVA Amco Veba 812 crane rotation movement is not regular?
If the rotation movement of your HYVA Construction Equipment crane is not regular, it could be because the vehicle is beyond the maximum inclination. Stabilize the vehicle within the maximum permissible inclination. It may also be due to the rotation flow control valve and/or shockproof valve on the distribution element being uncalibrated or dirty. Calibrate or clean the valves. Finally, it could be caused by a worn rotation cylinder seal. Replace the seals.
Why do HYVA Amco Veba 812 crane cylinders vibrate during first maneuvers?
Vibrations in the HYVA Construction Equipment crane cylinders, or jerky operation of the telescopic element cylinders during initial maneuvers, can occur if the oil temperature is too low. Perform empty maneuvers for a few minutes to warm up the oil.
What to do if HYVA Amco Veba 812 stabilizer cylinder retracts during operation?
If the stabilizer cylinder of your HYVA Construction Equipment retracts during operation, it could be due to wear of the locking valve on the cylinder or a lack of hydraulic seal. It may also be caused by wear of the internal seals. In both cases, it is suggested to visit an authorized service center.
What to do if HYVA Construction Equipment control levers do not result in any crane movement?
If operating the control levers on your HYVA Construction Equipment does not result in any crane movement, verify the presence of driving force. Also, check that the ignition key is inserted and the green light is on. Ensure the emergency stop button is disengaged after verifying there are no dangerous conditions. For a damaged emergency solenoid valve, it is suggested to visit an authorized service center.
