Compactness, performance and versatility.
Working free of emissions
The small, electric drilling rig KR 704-2E has been designed especially for working in confined spaces in urban environments. It allows you to work completely free of exhaust gas emissions and produce only very limited noise emissions.
Versatile applications
With a minimum basic rig width of 750 mm and the option to use telescopic drill masts, the drilling rig can manoeuvre in buildings with narrow doorways and low headrooms. This means that specialised foundation work can be performed even under difficult conditions, especially with the drill mast positioned vertically, e.g. micropiles and underpinnings of existing foundations using high-pressure injection columns.
Safe operation
The radio remote control of the drilling rig for all drilling, driving and set-up functions is in accordance with EN 16228. It allows the operator to decide where they want to stand during the drilling process. This is an important safety feature, especially in tight spaces.
Low headroom
You can make optimum use of low headrooms of 2.2m to 3.2m (or optionally 2.5m to 3.5m) by means of a telescopic drill mast. Drill rods and casings with an effective length of 1500 mm (or 2000 mm) can be used. The telescopic drill mast has a retraction force of 60 kN.
Sliding upper carriage
The hydraulic sliding upper carriage is a special feature of this drilling rig. From the supported position, a drilling position can be approached more easily and carefully.
Advantages
