This rotary head is a robust construction with a high torque of rotation capable of rotating DTH Hammers up to 6".
The central shaft is based on large conical bearings and has a central hole of 50mm.
Two hydraulic motors are responsible for its rotation by providing it with rich torque. With the use of a hand valve we alternate the way of connecting them from series to parallel and we choose whether we want slow turns and high torque or fast revs and low torque.
At the back of it is connected a separate rotary air connection with thread connection 2" and in combination with the large central hole of the central axis we can provide plenty of air or foam or even concrete to the drilling hole without being able to enter dirt in the central reducer.
At the front of it it has a flange which is held by 8 M16 screws which can rotate in both directions. So the rotary head can be rotated with load in both directions (ideal for use with augers). Even in the flange we can adjust threaded connectors API or various apliance eg. For rotating casing tubs or for screwing screws.
