The advantage of the latest generation of Delmag drilling rigs is the compact yet strong design combined with powerful and durable components like high-torque rotary heads and heavy duty winches. Further features are the use of special made carriers with telescopic undercarriages, parallelogram kinematics, revers-able winches for the crowd system, modern hydraulic and electric control systems and detachable counterweight. The mast is optimized for all drilling applications (Kelly drilling, CFA,
HPM short mast foundation rigs are the ultimate solution for making large diameter piles in restricted areas underneath bridges, high-voltage overhead or telephone lines and within existing buildings. The short drilling depth can be compensated by large drilling diameters up to 4000 mm.
When concrete piles of very large diameter or great depth are required, it is often more economical to excavate the pile using a pile grab which is hanging and operated by a crawler crane. To drive the casing and to extract it after concreting a hydraulic casing oscillator is required which is mounted in front of the crawler crane. If the crane has sufficient power, it can also operate the oscillator, otherwise a separate power pack is required.
Hydraulic casing oscillators (short version) are mounted in front of hydraulic drilling rigs when the torque of the rotary is insufficient to drive or extract the casing in case of large drilling diameter and/or depths or due to high soil friction. If the drilling rig has the necessary hydraulic power the oscillator can be controlled by the on-board hydraulics of the carrier otherwise by a separate hydraulic power pack. Hydraulic casing oscillators are required if the torque of the rotary of th
The STM series of Bentonite turbo mixers consist of a steel sheet cylindrical tank, set-up on a strong base frame, the pump and the motor (electrical, gasoline or diesel). The muds are mixed through a high speed vortex produced by a special pump which, after sucking the material from the bottom of the tank, sends it back tangentially into the same tank in order to get highest possible efficiency. Through a time controlled operation of the throttle valves of the system, the pump can bring the mud
The SD series of Bentonite desanders have been specifically developed for foundation applications. The Bentonite mud is reliably separated from all kinds of solids such as sand, clay, slims and other organic matters. The desander mainly consists of a setting tank, special centrifugal pumps, centrifugal separators, vibration screens and a patented control system. All wear parts are made of top quality, highly resistant and long lasting materials for extended durability and easy maintenance.
The HPD series of Bentonite desanders have been specifically developed for tunneling applications. The Bentonite mud is reliably seperated from all kinds of solids such as sand, clay, slims and other organic matters. The desander consists mainly of a setting tank, special centrifugal pumps, centrifugal seperators, vibration screens and a patented control system. All wear parts are made of top quality, highly resistant and long lasting materials for extended durability and easy maintenance.
The VIBROS STA are powerful and versatile soil compaction equipment for even the most difficult vibroflotation and stone column applications. The wear shield is made of special steel and easy to replace. Extension pipes for different lengths are available.
Pile Driving Analyzer (PDA) is a diagnostic tool for evaluating all kinds of foundation pile systems and is the most widely used system for pile driving analysis in the world. The PDA measures strain and acceleration under a dynamic impact and then evaluates shaft integrity and investigates driving stresses and hammer energy during pile installation. In addition the capacity of several piles can be tested in one day at typically 10 times less cost than for a single conventional static test. For
