Foreword:
General:
This crane was built according to the state of technology and recognized safety technical regulations.
Despite that, dangers to body and life for the user and / or third persons or damage to the crane and /
or other material assets can occur.
This crane may only be used:
– in impeccable technical condition.
– for destined use.
– by trained personnel, which acts in a safety and danger conscious way.
– when no safety relevant problems are present.
– when no modifications were made on the crane.
Any problems, which could affect safety must be fixed immediately.
Modifications on the crane may only be made with written approval by Liebherr-Werk Ehingen GmbH.
Data recording device
This crane is equipped with a data recording device. Among others, the following data is recorded:
– Date and time of day
– Entered configuration of the crane
– Actual load
– Percentage of utilization of the crane
– Working radius
– Main boom angle, luffing jib angle
