In principle, the truck crane must be sethorizontally on flat and solid ground. If the truck crane has to be operated on soft or gradientground, the crane’s outriggers must be horizontally set inspite of the conditions of supporting ground,and if necessary, a horizontal supportingsurface shall be shaped or the truckcrane shall be leveled with backup platecorrespondent to the ground. In addition, it’s forbidden tolay any outrigger on a hole at any time.

Crane for Sale, the maximumdeflection angle shall not exceed 0.5°. Alltires of the truck crane shall be off the ground and suspended,and any possible subsidence is forbidden.The stability of the supporting ground shall bemonitored always during the crane operation.In case of any factor that reduces thestability of the truck crane outriggers’ supporting ground, lay down theheavy stuff and retract the boom at once, andafter eliminating such factor, support the truckcrane as required again.
Heavy Machinery The factors reducingthe stability of truck crane include change of ground conditionsdue to rain, snow water or other watersources, subsidence of ground at the side ofoutrigger and leakage in outrigger cylinder.
