◆ Max. Hook load 198000lb(900kN),draw works installed power rating 360HP (269kW).
◆ Workover depth 8200ft(2500m)(3-1/2" drilling pipe),drilling depth 2380ft(1000m)(4-1/2" drilling pipe).
◆ Hydraulic driving base can be moved transversely and lengthways. Cluster well operation can also be performed.
◆ To raise and lower double-section telescoping mast hydraulically.
◆ Single diesel engine driving. Adopt international famous-brand engine and ALLISON hydromechanical transmission.
◆ Draw works drum: Integral Lebus groove will ensure that ropes are arranged in order. Band brake, forced circulation cooling, low pollution. Auxiliary brake is of hydromatic brake system.
◆ Operation control system is of centralized control and long-distance air control operation. The key parts have multiple protection functions.
◆ Rotary table has forward gear and reverse gear mechanisms. It also adopts DP torque release unit so as to prevent drilling string from reversing at a high speed and avoid accident.
