Control cylinder by cylinder :
• Position a load equal to the rated capacity on the cage (or platform).
• Perform the movement of the concern cylinder to half of its stroke.
• Fix the cylinder with a comparator :
• Attach the body of the comparator on the cylinder rod.
• The needle of the comparator must be in contact with the end of the casing of the cylinder.
• The target is to measure the creep of the cylinder rod.
• If the creep of the cylinder rod is higher than the values indicated in the table below, replace the
cylinder.
3.3.4 - Electric
3.3.4.1 - Replacing damaged cables
• Locate the faulty wire/s and its/their points of connection to ensure continuity of machine operation
after the wire is replaced.
• Note the cable path to facilitate reassembly.
• Respect the order (configuration) of origin during the reassembly.
