Intended use:
The GMK7450 truck crane is constructed in accordance with the latest tech- nology and the
recognised safety regulations. Nevertheless, the operator or third parties can still be endangered
and the crane or other property put at risk while using it.
- The truck crane may be modified only with the consent of Manitowoc Crane Group Germany GmbH.
- The GMK7450 truck crane may be used only when it is in perfect technical condition and for its
intended purpose and with due attention paid to safe operation and possible hazards.
Any malfunctions that could impair safety must be eliminated immediately. - The GMK7450 truck crane may only be operated without the corre- sponding special equipment within
the permitted temperature range;
à Technical data, p. 1 – 7. - The GMK7450 truck crane is designed solely for lifting loads which are within the permitted GMK7450
lifting capacities. The load must be slung as prescribed to a hook block which is positioned
vertically over the load prior to lifting.
Intended use also includes
– observing the entire crane documentation, consisting of the operating manual(s), the lifting
capacity table, the outrigger pressure table and the safety manual
– adhering to the inspection and maintenance requirements specified in the maintenance manual.
The GMK7450 may only be operated with parts of equipment that have been approved by Manitowoc Crane
Group Germany GmbH and which are labelled with the serial number of the GMK7450.
The manufacturer is not liable for any damage caused by improper or unau-
thorized use of the GMK7450 truck crane. The user alone bears the risk.
