Intended use:
The truck crane GMK 7450 is constructed in accordance with the latest technology and the recognized safety regulations. Nevertheless, personal injury to the operator or a third party as well as damage to the crane and other property may occur during use.
The truck crane may only be modified with the consent of the manufacturer.
The truck crane GMK 7450 may only be used when in excellent working condition and for its intended purpose, and with due attention to safe operation and any possible hazards. Malfunctions that may affect the safe operation of the unit are to be corrected immediately.
The GMK 7450 truck crane may only be operated at temperatures of between –25 to +40 °C (–13 to +104 °F) unless fitted with the appropriate special equipment.
The GMK 7450 truck crane may only be used to vertically lift loads in the authorized rigging modes using a hook block that is reeved to the hoist rope. The weight and centre of gravity of the loads must be known. Any other use of the crane is not considered to represent intended use.
The manufacturer is not liable for damage resulting from the improper or unauthorized use of the truck crane GMK 7450. The user shall take full responsibility for any such use.
Intended use also entails
– Following the complete crane documentation consisting of the operating
instructions, the lifting capacity table, the outrigger pressure table and the
safety manual
– Adhering to the inspection and maintenance requirements specified in
the maintenance manual.
Improper use includes:
– Transporting loads on the carrier
– Pushing, pulling or lifting loads with the level adjustment system, the
beams or the outrigger cylinders
– Pushing, pulling or lifting loads off the ground using the slewing gear, the
derricking gear or the telescoping mechanism
– Pulling off fixed objects using the crane
– Two-hook operation with the boom extension and two-hook operation on
the main boom head without additional equipment
– Operation when crane is not on outriggers (free on wheels)
– Defining SLI codes that do not correspond to the actual rigging mode
– Working with an overridden SLI or overridden lifting limit switch
– After SLI deactivation, increasing the radius by pulling the raised load at
an angle (e.g. with a chain hoist)
– Misuse of the outrigger pressure indicator as a safety function to prevent
overturning after an SLI shutdown (outrigger pressure greater than 0 t)
– Road driving in an unauthorized driving mode (axle load, dimension)
– Moving the rigged crane in an unauthorized driving mode
– Use of equipment that is not authorized for use with the crane
– Transporting people in any way with the lifting tackle, upon the load, or in
the crane cab while driving
– Carrying passengers outside the driver’s cab
– Loading and unloading work, i.e. continuous operation without a sufficiently
long break
– Usage for any kind of sport or recreation event, especially for bungee
jumping
– Operation of the truck crane with erected and non-braced MWL with
rigged lattice extension.
