1.Adopting the octagon column with the features of lighter weight and stronger carrying capacity.
2.The versatility and interchangeability of each column make it convenient to add (remove) pipes and ladders when adding (removing) columns.
3.Brand new design of climbing structure makes it convenient to trepan and operate.
4.Four arms design. Arms adopt high strength steel plate which is stronger and lighter. And the 4th arm can slew 210°with wide working range.
5.It is easier to meet the hoisting requirement of the jobsite for its lighter weight of lifting units.
6.The hydraulic system is optimized and the volume of hydraulic oil tank is reduced, which reduces the cost of maintenance.
