1.The folding mast structure has the advantages of simple, great durability, saving cost and making repair more convenient.
2.Using
the high position-oriented structure for the frame, which guarantees the verticality between kelly bar and ground, kes constucture more convenient, improves work efficiency, increses safty.
3.Power head adopts unique patent structure, which save cost and make repair more convenient.
4.Main windlass: Adoptin original imported hydraulic pressure motor from Italy. It has sensitivereaction and can free down, which speed can be up to 80m/min and improve the construction efficiency. Main winch lays in the cavit of te U-shape, whchlocates in the operator's right field of vision (enables operator to obseve working condition of main winch freely). This kind of situation is not only simple but also practical.
