| Tallving systems |
| |
Travelling system is intended for round-trip operation, drilling pipe and casing string suspension during oil and gas well drilling. Travelling system includes crown block, traveling block and hook block. Some systems have traveling block and lifting hook joined in one mechanism hook block. The main engineering data is given in Table. |
