Construction Description
Under basic jib, the hoisting range of our company’s QY25C truck crane is 5.2 meters and the multiplying factor is 8. At that moment, we were lifting the oil transferring steel pipe of drilling equipment from CNPC, which is 19 tons heavy.

When pipe coming off from the ground, it would hit the rear outrigger because the lifted steel pipe is up to 10 meters long. We lifted the steel pipe slowly, and until it is lifted to 3 meters high, we lay it on the nearby platform lorry. Under this working condition, only those operators who are very familiar with operation of SANY branded crane, because it belongs to overload lifting.

When jib is 15.4 meters long, the hoisting range of our company’s QY50C truck crane is 5 meters and the multiplying factor is 12. At that moment, we were lifting the oil transferring steel pipe of drilling equipment from CNPC, which is 34 tons heavy. First, we lifted the steel pipe up to 3 meters high, and then drive the platform lorry below the steel pipe. Thus, it becomes much easier to put the steel pipe to any specific position.


Under 33.5-meter full jib, the hoisting range of our company’s QY25C truck crane is 6 meters. At that moment, we were lifting the cables of drilling equipment from CNPC, which are 4 tons heavy. When lifting such heave objects under full jib, the heavy objects can be moved due to heavy wind. Under that circumstance, slight mobility is quite important. Either moving the roll filed or rotating reversely can cause heavy object hitting the main jib, which is very dangerous. However, under that dangerous circumstance, SANY branded crane perform very well and works stably, which can absolutely prove the quality of SANY branded truck crane has been recognized by the whole society.
