Notes
a Telescopic mast.
b Standard rigs, additional leader extensions available for pile lengths up to 30 m.
c Using swinging leader.
The ABI Mobilram TM series of telescopic leader masts (Figure 3.1) provide ‘crowd’
(pulldown) for driving piles up to 21 m long using vibratory drivers, but fold down for compact
transport. The Banut 555 and 650 piling rigs (Figure 3.2) are not only specially
designed for impact driving, primarily precast concrete piles but are also effective for most
bearing and sheet piles. The hydraulic stays attached to the crawler enable forward rakes of
up to 18 o and 45 o back rakes, together with lateral movement of up to 14 o available on both
units. The usable length given for the 650 unit relates to the Banut superRAM 6000
hydraulic hammer (see Table 3.2).
The Junttan PM hydraulic piling rigs with fixed leaders can drive piles ranging from 18
to 36 m long (for HHK hydraulic hammers with leader extensions), using hammer rams
from 3000 to 12000 kg. Fore and aft rakes of 18 o and 40 o respectively and lateral raking up
to 12 o are available on the PM25 unit. Liebherr provide fixed leaders mounted on their own
and others’ crawler carriages. The LRB series can operate as pile driving rigs and rotary
drills for CFA and kelly bored piles.
