Drilling Rig By Cangzhou Boda Petroleum Machinery Development Co., Ltd.

These Drilling Rig is driven by diesel engines, hydraulic coupling & chain compound box or diesel engines, reducers & narrow V-belt, which provides smooth mechanical power to the drawworks. A number of hoisting speeds and rotary speeds are available.
The drawworks is divided into tow sections so as to install the main drawworks at ground level. The tapered gear box and universal shaft transmit smooth power to the equipment on the drill floor for ease of assembly/disassembly.
The main drawworks(40 and 50 model)utilize air clutch for shifting gears,which are suitable for remote control. The catwalk is equipped with a sand reel, of entire&combination construction.
The main brake uses either a band brake or a hydraulic disc brake. And the auxiliary brake adopts either an eddy current brake or EATON brake. The system provides a high degree of sensitivity and reliablity to reduce intensity of driller's labor.
The chain driven rig is driven by the integral enclosed compound chain box(or narrow V-belt)and coupling. During any rig moves, it is unnecessary to dismantle the chains(or narrow V-belt)for fast installation.
The mast is of open-front type without guy line. It is integrally raised and installed at ground level.
The substructure is of a box-on-box type. It is simple in structure and easy to install.
