| ProductName:QTZ31.5 |  | | ProductNO.:Pro200931522333 | | Maker:HengSheng | | Price: | Order: | |  |  | | super-long crane beam (38.6、42m)，broad coverage area
·big standard knot section(1500×1500)，good rigid，the whole machine is stable, and swings small when lifts,
· materials of main limbof model of standard knot is large(∠140×140×10或∠125×125×10)
· Electrical System uses good quality components，performance is stable and reliable.
Major components (parts) such as standard knot connect cap、road、up an down turntable etc. use
Carbon dioxide gas to weld, the penetration depth is big but the deformation is small ·basis of this tower crane: concrete-type、heavy
