Product Description

Product Description

Workover rigs are the most basic and most important power source in well intervention and underground operations, it's purpose is to replace a well with a fresh completion. BOBAN XJ750 mobile truck-mounted workover rigs with features like high operates efficiency and fast moving speed, easy to use and maintenance.

BBXJ750 is a kind of Truck-mounted workover rig equipment, Max. hook load 1800KN, mast height 36m, workover depth 8000m (2-7/8 drilling pipe), nominal workover depth 6500m (3-1/2 drilling pipe), drilling depth 3000m(114mm drilling pipe).

It's divided into two parts:  
1. Special- purpose chassis, drive type 14*8 or 12*8; 
2. Special working equipment for workover.

Mast Assembly
Adopts structural mast, the hydraulic cylinder carries out lifting. Slant degree: 3.3, the mast upper body bearing unit equipped with cylinder bearing organ that is the turning block type, which structure is simple, safe and reliable.

Drawworks
Single drum structure, maximum capacity 280 KN, band or disc brake, with features compact structure, high efficiency, long service life.

Hydraulic Control system
Hydraulic oil pump using the fouling resistance gear oil pump, reliable performance; The reversing valve adopts manual and pneumatic control structure, the operation is simple and effort, concise line layout.

Main Application
Used for workover with:≤8000m depth, oil, water, oil, drilling for:water, gas.
