Information on
the axle loads
The GMK5250L truck crane is designed for driving with maximum axle
loads of 12 t (26,500 lbs).
Manitowoc Crane Group Germany GmbH notes that
driving with an axle load exceeding 12 t (26,500 lbs) the brake system can
overheat and the braking deceleration required by the EU partial type-
approval cannot be ensured.
If country-specific regulations allow the truck crane to be driven with axle
loads greater that 12 t (26,500 lbs), the crane driver/crane operator bears the
sole responsibility for driving in this condition and for any subsequent dam-
age. This also applies to damage due to premature wear.
G
Risk of accidents from increased braking distance
When driving with axle loads in excess of 12 t (26,500 lbs), the braking
deceleration required by the EU partial type-approval cannot be met. Please
bear in mind that the braking distance of the truck crane will be increased.
S
Risk of damage from premature wear
Premature wear of parts under particular strain (brake system, steering,
tyres, wheels, suspension, drive shafts) cannot be ruled out even if the axle
loads only briefly exceed 12 t (26,500 lbs).
