>>>Introduction of 4ton tower crane:
QTZ40-4808 top kits tower crane is a mini tower crane to lift various material in construction field. It is characterized by creative design with rational structure and reliable operation. Its maximum load is 4t, tip load is 0.8t, jib length is 48m, free standing height is 29m, maximum anchorage height can reach 120m. Equipped with all necessary safety devices, this construction equipment is superior to its counterparts not only in its original design, attractive appearance and secure operation but also in its extraordinary speed-control ability and work efficiency.
>>>Main Fature of 4ton tower crane:
1.It has ultra long arm and large coverage area.
2.The standard segment section is wide. Rigidity is good. Complete machine is stable and swings slightly when craning.
3.The standard segment principal branch is big.
4.The electrical system uses domestic high quality or importing parts. Its performance is stable and reliable.
5.The standard segment, drawbar, top-bottom turntable and other major components is welded by CO2 which penetrates deeply and deforms smally.
