求翻译：表示额定悬点载荷为60kN，光杆最大冲程4.5m，减速系统输出最大扭矩30kn，吊重式平衡的低冲次型塔架式数控抽油机（D代表低冲次型）。是什么意思？

Said rod load rating for the 60kN, the largest rod stroke 4.5m, maximum torque deceleration system 30kn, lifting the low-type balanced type of stroke pumping tower rack NC (D impulse times on behalf of low-type).

Expresses its rated hanging point kN payload, Kwong-under-par 60 in the largest stroke 4.5 m, maximum torque deceleration system output 30 kN, and Hoists are the low-flush-style balance in transition time frame CNC pumping Taliban representatives (D low flush type) meeting.

Expressed the fixed center or point of suspension load is 60kN, polished rod biggest stroke 4.5m, retrosystem output maximum torque 30kn, the crane type balance lowly flushes the time tower type numerical control pumping unit (D to represent flushes time lowly).

Polished Rod load rating is 60kN and polished Rod 4.5m the maximum stroke, deceleration system output maximum torque of 30KN, load balancing of low stroke of Tower-type CNC pumping units (d for low stroke type).

Expressed the fixed center or point of suspension load is 60kN, polished rod biggest stroke 4.5m, retrosystem output maximum torque 30kn, the crane type balance lowly flushes the time tower type numerical control pumping unit (D to represent flushes time lowly).
