ABSTRACT:
A fluid supply line13connects the hydraulic fluid supply pump11to the hydraulic balancing pipe9, and this line13is fitted with a solenoid valve15. Position detectors17, 18are installed on the auxiliary arm4and on the main arm3close to the articulation of the counterweight balancing beam5. If the main arm4is detected to be in its pendular position before the counterweight balancing beam5is detected to be in its vertical position, the logic controller16controls activation of the solenoid valve15in order to add hydraulic fluid to the jack8in order to bring the balancing beam5in vertical position.
