1.BRIEF DESCRIPTION

Sincep productsworkover rig has XJ15, XT20, XJ30, XJ40 series, the series of workover rig ismainly composed of vehicle chassis, PTO with the pump box, torque converter,transmission angle gearbox, winch and crane control system, anti collisionemergency braking system, derrick and hoisting system, weight indicator andcentralized control of the liquid gas system. According to the needs of users,various types of workover rigs can be equipped with  1.5~3 tons hydraulic winch, XJ30, XJ40 andother series of workover rigs can be equipped with rotary transmission device,mechanical or hydraulic turntable, drill station and swivel head system .

Workover rigsusing domestic heavy off-road chassis, XJ15, XJ20 series workover rigs usingchassis of Hongyan, Yanan, FAW, Dongfeng; XJ30, XJ40 workover rigs usingchassis of cavalry, Steyr, North Benz and T815. All chassis have been used inthe oil field, with good guarantee service.

according to different user requirementsoperation, the power source for workover rigs has the following two ways:

(1)transport andoperation by same one engine, and the power of the operation is provided afterthe full power take-off mechanism.engine PTO pump boxHydraulic torque converter, angle drive box, winch, clutch winch

(2)Use exclusiveengine, add another engine and a hydraulic gear box are installed on thevehicle, and the power of workover operation is provided separately, and theindividual power is used for driving and operation Engine, hydraulictransmission, angle drive box, winch, clutch, winch。

XJ30, XJ40series workover rigs can also use our 6x6 drive chassis, host is equipped withthe Caterpillar CAT3306 engine, Allison HT750DRDB gear box, TC497 converter,also can be equipped with the same power of domestic engine and hydraulicgearbox, engine, torque converter and gear box.
