Service
Barrier units are not maintenance free and therefore need regular inspection. Hereby the number
and extent of the inspections depend on the frequency of use (number of cycles) and where the
unit is placed and less on the time span since the previous inspection. The operator must keep
an inspection record of all risks which describes and confirms the extent of the inspection.
An inspection record should contain:
• Visual inspection:
apparent deficiencies, damages through vehicles, environmental influences
or vandalism. Visual inspection of safety installations and signposting. Frequency: depends on
where unit is placed and vehicle frequency: daily ? monthly to be carried out by a qualified /
experienced person (janitor, technician)
• Inspection / service:
in addition to visual inspection. Complete inspection of unit regarding
mechanical signs of wear. If necessary exchange parts and repair.
• In order to make use of the guarantee it is necessary to conclude a maintenance contract with
the operator of the unit and to have regular maintenance / inspections of unit carried out.
