3.3.3.3 - Evaluation of leaks on hydraulic cylinders
These measures must be taken each time an anomaly has been detected in the hydraulic
cylinder during daily inspection and periodic maintenance checks.
Generic Control :
• Position a load equal to the rated capacity on the cage (or platform).
• Raise the cage (or the platform) using the ground control box. To activate the cylinder to be tested,
proceed as follows :
• Lift Arm hydraulic cylinder : Lift the arm to approximately half full height. The telescopic boom should
be fully extended and in the horizontal position. (For machines fitted with).
• Boom lifting cylinder or Jib cylinder : Lift the concerned equipment (boom or jib) of approximately half
way. Extend the telescope to its maximum.
• Telescoping cylinder : Lift the boom to its maximum angle and telescope approximately 50 cm.
• Measure the distance between the floor of the cage (or of the platform) and the ground.
• Leave the machine in this condition for 15 mn (minutes).
• Measure the distance between the floor of the cage (or of the platform) and the ground.
• If the difference between two measurements does not exceed 4 cm : the test validates correct
operation.
• If the difference between two measurements exceeds 4 cm, contact HAULOTTE Services® or carry
out the additional tests described below.
