If due to exceptional circumstances the truck crane needs be put into
operation for certain types of maintenance work, great care must be taken
where there are moving parts (superstructure, outriggers, Cardan shafts,
slewing bearing, engines, tiltable crane cab). There is a risk of injury.
• Ensure that all hydraulic components are returned to their initial positions
(e.g. the main boom) or locked (e. g. the outriggers) before starting
maintenance work.
Escaping hydraulic fluid or compressed air can cause severe injury.
Remember that the
hydraulic and compressed air systems of the truck
crane are pressurised even when the crane is not in operation. Tighten
loose screw connections only when the systems are depressurised.
Always depressurise the hydraulic and compressed air systems before
opening them.
• Do not allow hot fluids to escape in an uncontrolled manner. Risk
of scalding.
• Observe the applicable safety regulations when working with flammable
fluids.
• Observe the applicable safety regulations when working with process
materials.
• Switch off all electrical consumers and first disconnect the earthing
terminal before removing any electrical batteries.
• Keep in mind the corrosive effect of battery acid.
• Note the fire alarm and fire-fighting facilities on site.
• Return the truck crane to proper working order once maintenance work
is completed. Inform the crane operator accordingly.
