ZP495 Rotary Table Drilling rig

Major features:

1. It adopts integrated design of mechanical, electrical, hydraulic, pneumatic and digital control, utilizes fully the advantages of advanced digital control AC VF electric transmission, and simplifies its mechanical structure.

 

2. As adopting of slingshot type substructure, drill floor equipments and driller cabin etc realize low-position installation and integer lifting.

3. Electric transmission adopts vector VF drive system to realize all digital operation and control, and also processes elementary functions of automation, intelligence and information to realize collection (signal), display, restoration, printing, remote monitoring and management of control and drilling parameters.

 

4. By the use of VF technology, DW realizes max torque output when its speed is zero to ensure the suspension function of rig lifting system, which change traditional driller operation mode completely.

 

5. This rig is equipped with an integral driller's cabin, in which a driller can finish major operations.
