D5.1 Overview
Malfunction
Cause
Remedial measure
Cylinder sinks
Air in the hydraulic system
Vent the system, see D5.2.
Load safety valve is defect
Replace climbing device.
Repairs carried out by PERI.
Sealing is defect
Replace climbing device.
Repairs carried out by PERI.
Uneven cylinder
extension and
retraction
Air in the hydraulic system
Vent the system, see D5.2.
Dirt in the hydraulic
system
Replace hydraulic oil, see C3.4 and, if
necessary, clean hydraulic tank and oil filter,
and replace, see C3.5.
Synchronisation deviation
Carry out a reference run, see D5.3.
Leakage between pump
and cylinder
Retract all cylinders in order to lower the
climbing unit on the climbing pawls. Identify
leakage point and seal; replace if necessary.
Flow divider defect
Carry out a reference run, see D5.3.
Repairs carried out by PERI.
Climbing rail does not
insert into the shoe
or climbing is not
straight
Lateral offset through
synchronisation deviation
Extend cylinder to the same height,
see D5.4.
Climbed too far
Retract all cylinders in order to lower the
climbing unit onto the climbing pawls.
Contact PERI.
Hydraulic oil leaks
Hydraulic hose is broken
or leaks
Immediately stop the climbing procedure
and replace the hydraulic hose.
Check all hydraulic hoses.
Leaking hose connections
Switch off the hydraulic pump = pressure
relief. Tighten hose connections.
