The DDW-3000 HDD Rig is the special equipment designed for the large pipeline crossing projects. The mast，power source and cabin are mounted on the steel crawler chassis. The mast consists of the double gear-rack track and the push plate track. The hydraulic clamp has the opening scope from 140 to 260mm on diameter and can move along the rack within the whole distance. The hydraulic system is applied with the variable system，which is more energy-saving. The control system is widely used with electron-hydraulic control mode，etc. Safe and reliable skid-proof platform is used to auxiliary crane operation control and rotary head maintenance，etc. Rig is run by one operator to complete loading and unloading work. The machine boasts the high performance price ratio.
Features：
1. The main axle is moveable which can more effectively protect the thread of the drill rod and mud passage.
2. Operational platform is adopted with the ergonomic design：pilot control handle is comfortable for operation.
3. The main hydraulic pressure components are imported.
