Configurations
BG 11 H
The BG 11 H ValueLine is a compact
drilling rig which easily can be modified
for various applications:
Standard configuration
Typical basic configuration for standard uncased bored piling
operations in Kelly mode.
It ranges to drilling depths of 40 m (130 ft) with 4-part lockable
Kelly bar and for borehoile diameters up to 1,200 mm (3.9 ft).
An optional casing drive adapter allows the installation of
temporary casings with a maximum section length of 2.5 m
(8.2 ft).
Rathole drill configuration
Special configuration for the construction of preparatory
boreholes when constructing oil and gas wells.
The BG 11 H ValueLine can construct short cellar holes with
big diameter up to 3 m (10 ft), followed by drilling conductor
holes, ratholes and mouseholes.
Special attention was given to the possibility of reducing
the transport weight to a minimum of 34.0 t (74,960 lbs)
by using a specially designed multi-piece, removable
counterweight.
Low head drill configuration
Removing of the upper mast section enables the
construction of boreholes to a maximum depth of
19 m (62.3 ft) with a minimum working height of 10 m
(32.8 ft).
When extending the horizontal reach, the top of the
mast can be lowered to a height of 8.9 m (29.2 ft).
