D7-S25 (PM85)

D7-S25 (PM85) is a drilling/piling mast attachment for driving steel piles up to 220 mm, or drilled piles up to 323 mm


S25 is SPD’s own carrier, specially developed as a carrier and drive source for SPD’s drill and pile masts
S25 is more efficient and better suited than any excavator on the market due to the following arguments
3 large Rexroth pumps, one pump only for rotary, one pump only for percussion, one pump only for set-up functions and feed, normally in a regular excavator there are usually two pumps that are interconnected and you get operational disturbances when the oil is not enough to drive several functions at the same time
Extremely low fuel consumption due to the efficiently designed hydraulic system
SPD telematic, GSM for logging all important machine data, warnings, error codes, troubleshooting, drill data, piling data, fuel consumption, hydraulics log, diagrams online, saved max for two years
The machine is always remotely controlled with CAN bus technology, therefore the cab is not needed, i.e. there are no unnecessary functions, remote control from HBC / SPD
The remote control has a color display for displaying all machine data, drill or piling data
Where the cabin would normally sit, we instead have a heating cabinet for water pumps and water pipes that must not freeze
S25 available with or without extendable undercarriage
The S25 has a powerful Cummins 6.7 liter diesel engine of 209 kW
All machine doors open upwards and form a roof when serviced
All tanks, diesel, adblue, tank pump, central lubrication, electrical cabinets, etc. are easily located on the same side of the machine
