Concrete casting reel second generation

We at GDS are happy to introduce our second generation of our concrete casting reel that now stand finished and are ready for casting missions. The reel does not have to be connected to the carriers hydraulic system anymore, now it requires only 32 A electrical connection for full functionality.

Benefits of the second generation:

-own power supply through a hydraulic package
-built in air compressor
-developed control system for quality-assured casting and documentation

GDS concrete casting reel offer following benefits unlike conventional pile casting:

-enables casting in higher capacity
-economical and lower carbon dioxide emissions when using concrete
-can also be used to clean the poles before casting, hence used as a mammoth pump

SOLO 400 EF flying over Södermalm

GDS has recently delivered SOLO 400 EF, an electric pump for water powered drilling, to Besab on Södermalm in central Stockholm for rental. The purpose of the project is to perform drilling and strengthen the foundation near older buildings. This project takes place in the central parts of Stockholm and therefor Besab chose to use SOLO 400 EF for environmental reasons. The pump is electric driven and therefor very quiet and does not emit any exhaust fumes. The pump is suitable for drilling with 3”, 4” and 5” water hammers. Please read more about SOLO 400 EF here.

Deep drilling project for gas in Siljansringen

GDS deliver and rent out equipment for a deep drilling project for gas in Siljansringen. The aim of the project is to reach gas formations down to 1000 meters depth. The drilling takes place with water hammers. Due to limited access to water, most of the drilling water is recirculated and reused.

GDS answers for high-pressure water pumps for drilling, sedimentation, filtration and purification of the drilling water and also water hammers and diamond coated DTH-drill bits. Amongst others, GDS delivers high-pressure water pump TWIN 850 in a redundant system with several pumps. Enjoy more reading about the TWIN 850 pump here and Siljansringen on Wikipedia.

GDS has recently delivered SOLO 400 EF, a high-pressure water pump for water powered drilling with electric drive. The pump will go to a project in Austria and is convoyed through our sister company TDS Tunnel Drilling Solutions. The pump will be used by the German mining and special ground engineering company Thyssen Schachtbau in the Semmering Base Tunnel project, which takes place near Vienna and is currently one of the biggest tunneling projects in Austria.

SOLO 400 EF, GDS electric driven high-pressure water pump, has a capacity of 400 liters per minute and 200 bars. The pump is suitable for water powered drilling up to 5” hammers. Thyssen Schachtbau is using this pump for WAI hammer drilling; WAI50, 40 and 35. It has a power of 140 kW and is frequency converter driven which makes it adjustable within a large work area and very energy efficient.
