Drilling rigs - single components
Our drilling rigs are equipped with components, which are designed in-house and are especially made for the needs of these drilling rigs. Thus these components are designed and completely produced by TH, we can adjust each part to your needs.
Our top drive may be driven in 2 different speed levels. This is realized with a so called hydraulic rapid feed control. On the one hand, there is the rapid feed, which is designed for high rotation speed and low torque. On the other hand there is the force feed which is designed for low rotation speed and high torque transmission.
We do offer 2 different types of our top drive which may be equipped for your needs. Their power spectrum lasts up to the following values:
|Torque in force feed||20.000 Nm|
|Rotation speed in force||0-70 r/min|
|Torque in rapid feed||2200 Nm|
|Rotation speed in rapid feed||0-300 r/min|
It is possible to generate higher torque transmission by operating in intermittent mode.
TH-drilling rigs are produced with a double collet chuck design. In this configuration the lower collet chuck has a variable bar-diameter and fixed positions. The upper collet chuck does have a fixed diameter (mostly) and a variable position. In fact it is possible to proceed a stroke of 500mm. With that, the initial drilling through loose sand is possible without using the lower collet chuck or the top drive.
|Drag force||up to 5000 daN|
|Copressive force||up to 2500 daN|
Hydraulic actuated chuck head. With the help of the tensible cone the drilling bar will be fixed in its place. With that, the rotating movement, given by the top drive, will be carried on to the bar. The TH-Chuck-Head brings huge advantages in connecting and solving the connections in the bars.
The Main winch is available in two different sizes, by default:
- Drag force up to 10 ton
- Drag force up to 20 ton
Different sizes are available, on demand
|Drag force||up to 20.000 daN|
|Lowering / dragging speed||up to 1 m/s|
|Rope-admittance||up to 110 m|
|Rope Ø||18 mm|
The Auxiliary winch is available in two different sizes, by default.
- Drag force up to 1,5 ton
- Drag force up to 3,0 ton
Different sizes are available, on demand.
