General Remarks
The Hydraulic Spherical Grab type HLKG is used on
jobs, where drilling has to be carried out free of vi-
brations 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 hydrau-
lic turning device enables the grab to be turned
100° to ensure a calibration of the borehole.
To recognize and correct any deviation of the verti-
cal excavation direction, all hydraulic spherical
grabs are equipped with a two-axis inclination sen-
sor. The inclination sensor values are monitored in-
side the operator’s cabin. For uncased drilled shafts
the grab type HLKG “CD” is used. The jaw dimensi-
ons are adapted to the respective shaft diameter.
