STETON S800 Horizontal Directional Drilling Rig
The S800 is the entry model of the maxi range, picking up where the heavy class ends. With 800 kN of thrust and pullback, 40,000 Nm of rotary torque and 800 L/min of mud flow, it installs pipe from Ø300 to Ø1200 mm on crossings reaching 1000 metres. Its 4,500 mm rods and 9,600 mm frame call for a tighter set-up area than rigs of comparable capacity, which shortens site preparation on river and motorway crossings. It is the right starting point for large-diameter water, sewer and gas transmission mains that the 60-tonne class cannot carry.

Call about this machine!+90 533 075 0222Which projects is the S800 for?
A maxi class for river and strait crossings, marine outfalls and large-diameter transmission mains. It works on single crossings approaching a kilometre and on pipe diameters beyond what the mid classes can carry. Site footprint, transport and crew planning are set per project; the rig is supplied to order.
Share your pipe diameter, crossing length and soil class; we will confirm over the phone whether the S800 is enough for the job, or whether the class above or below fits better. Rig selection guide →

About the STETON S800.
How much pullback does the STETON S800 have?
Push/pull force is 80 tonnes. As pipe diameter and crossing length grow, the rig is chosen with a margin above this figure.
Which projects suit the STETON S800?
A maxi class for river and strait crossings, marine outfalls and large-diameter transmission mains. It works on single crossings approaching a kilometre and on pipe diameters beyond what the mid classes can carry. Site footprint, transport and crew planning are set per project; the rig is supplied to order.
Which rods and bits work with the S800?
Rods matched to the rig thread standard, a directional bit or rock bit chosen for the soil class, a sonde housing, reamers and a swivel. All of it ships from Boremak stock; share your soil survey and we will specify the tool set together.
How much does the STETON S800 cost?
The price depends on the rod package, initial tooling set, locating system and delivery terms. Call us for a firm quotation on the S800.
