Vibrotech T-800” is INDIGENOUSLY
manufactured,
 hydrostatically driven
all drum drive double drums
vibrating tandem roller at par with
the INTERNATIONAL STANDARDS. The
hydrostatic drive allows smooth
speed for forward and reverse
motion. The vibration drives are
also hydrostatic and disconnect
automatically when machine stops.
Various combinations of vibrations
can be selected using the selector
switch on panel board. These
combinations are
High Vibration - Front drum only,
Rear drum only, both drums
Low Vibration - Front drum only,
Rear drum only, both drums
The prime mover is Kirloskar HA-494
air-cooled diesel engine developing
74 HP at 2500-rpm
SALIENT
FEATURES:
-
An advance feature like auto
vibration cut-off facility
ensures that it will not sink
even on tender bituminous
surface while slowing down on
hot asphalt.
-
The all round view from driving
position permits good visibility
and control of drum edges
compaction.
-
Universally accepted two piece
articulated design chassis with
hardened/ easily lubricable
center pin. R&D tested design by
world leader for they're proven
vibratory rollers.
-

(drive & vibration), a house of
proven hydraulic accepted
worldwide.
-
Hydraulic traction compact motor
from L&T (Poclain design) with
parking brake. Hydraulic
pressure line micron filters.
-
