2. Main body of Derrick is laminar structure which is easy to assemble & disassemble and transport.
3. Major stressed parts of Derrick such as legs and A-frame are made from H-steel.
4. Adjustment of center of well: its left and right direction is adjusted by adding/reducing pads under bracket of Derrick and front/ rear direction is adjusted by eccentric wheel at rear bracket of A-frame (however, if bracket of derrick’s leg is below sub-structure, it is adjusted on the floor).
