3 Hydraulic Casing Rotator RDM/RDM-M General Remarks RDM-M 2000 in operation The hydraulic full 360 degree turning casing rotators are economically used to construct bored piles with the full casing method under hard soil conditions. The continuous cutting of the hard ground guarantees a boring speed satisfying today's requirements, even for compressive resistance of up to 2500 kg/cm 2. The full 360 degree continuous turning of the casing minimizes the friction compared to the oscillating method allowing the casing to drill down to 100 m depth with the casing rotator machines. The full 360 degree continuous turning of the casing by powerfull hydraulic motors eliminates the possibility of pile misalignment. Beyond that, the casing rotators are especially suitable for the construction of full casing displacement piles because of the ability to apply very high torque, push down and lifting forces on the casing which is not possible with the known drilling rigs. The first casing is fitted with carbide bits which can be adapted to the requirements of the soil conditions offering major advantages when coring through hard rock layers or when constructing secant walls. 3

5 Hydraulic Casing Oscillators VRM General Remarks The hydraulic casing oscillators have been designed in accordance with the latest technical know-how. Extremely sturdy construction guarantees cost-effective use on site. By means of exact statical calculations in conjunction with higher quality material, an optimum conformity of loads, weight and material strength is achieved. The internal wielding stresses difficult to determine for static calculations, which would affect the construction considerably are eliminated by means of stress relieving prior VRM 3000 in operation to machining. A prominent feature of the equipment is the clamping collar consisting of five links operating on the boring implement. The individual links surround the casing like a chain so that a consistent surface pressure is exerted on the casing circumference. In addition, the large height of the collar (600 to 800 mm) prevents any damage to the casings. By means of easily exchangeable reducer pieces the oscillator can be converted, within a few minutes, to a smaller casing diameter. The collar opens uniformly and enables unproblematic insertion of the casing with the cutting shoe. Another advantage of the machine is the low height on the excavator side. The excavator can be swiveled by 360 in coupled condition. Attachment at the excavator itself is torque rigid and guarantees the transmission of the full rotating movement of 25 to the casing if the excavator is firmly situated. The design and construction of the casing oscillator is based on the experience of many years of co-operation with companies specializing in pile foundations. In view of the high costs which would result from a breakdown of the equipment on-site, great emphasis has been put on exeptionally sturdy construction.

24 Hydraulic Spherical Grab HKG/HKG CD General Remarks The Hydraulic Spherical Grab type HKG is used on jobs, where drilling has to be carried out free of vibrations and/or where partially cased or uncased drilled shafts are to be produced. The high deadweight in conjunction with the high closing force ensures a high efficiency. The hydraulic turning device enables the grab to be turned 100 to ensure a calibration of the borehole. To recognize and correct any deviation of the vertical excavation direction, all hydraulic spherical grabs are equipped with a two-axis inclination sensor. The inclination sensor values are monitored inside the operator s cabin. For uncased drilled shafts the grab type HKG CD is used. The jaw dimensions are adapted to the respective shaft diameter. 2 1 B1 S Pile diameter Type 1 2 B B1 B2 S Weight Capacity 1200 cased 1200 uncased HKG1-118 HKG CD 5760 mm kg l cased 1300 uncased HKG1-130 HKG CD cased 1500 uncased HKG1-150 HKG CD cased 1800 uncased HKG1-180 HKG CD cased 2000 uncased HKG1-200 HKG CD
