We can manufacture and include a new API splined quill at extra cost with your choice of API threads. The top drive is built with a large 10″ bore female splined main shaft which allows a splined quill to be dropped in and exchanged with min down time. This top drive was used for years on the drillship Joides Revolution until it was replaced with a new technology top drive system costing millions of dollars.
Pipe handler & torque reaction is an easily attachable separate system which attaches to the two side pins. It is not included but can be located for approx. $20-$30,000.
The TDS-3 top drive was designed to be suspended from a 500 ton rotary swivel which is not included but may be obtained in various brands at low cost.
Unit could also be used as a special torquing/rotating device other than a top drive. It has a 10:1 gear ratio and could be powered by other than existing motor, ie AC motor or hydraulic motor. We could help with such adaptation.
