When it comes to placing the right amount
of material at the correct grade and slope
in one pass, whether on a shoulder or
elsewhere, the best equipment for the job
is a Weiler road widener.


A 3.5 yd3 (2.6 m3) hopper means fewer
truck exchanges during the workday. The
24” (610 mm) wide belt and 400 fpm (121
mpm) belt speed provides quick placement
of materials to either side of the machine.
The hydraulically adjustable dump hopper
accommodates varying trucks.


25” (635 mm) tall strike-off tools widen
from 1’ (.3 m) to 10’ (3 m) and are capable of
placing material up to 12” (305 mm) above
and below grade. Multiple tool sizes plus
hydraulically adjustable tools ensure precise
strike-off and can be set to exact grade and
slope specifications.


The W530B has the power to push. The
two 2-drive version features a Cat® C3.6
Tier 4F/Stage V engine with 120 hp (89 kW) while
the 4-wheel drive features 137 hp (102
kW). Hydrostatic powershift drive with 2-speed motorand 2-speed gearbox delivers 350 fpm
(106 mpm) working speed and 12 mph
(19 km/hr) transport speed.


All controls are located on a single panel
within easy reach of the operator. Sliding
control console enhances operator ease
of use, enabling both left and right side
access to all machine controls. The operator
is located back from the dump hopper and
toward the outer edge of the machine for
increased visibility.


Self cleaning pulleys minimize material
build-up and large doors enable easy access
to engine and machine components. Built-in
tool storage locations provide home spots
for all components needed on the job.
Caterpillar dealer service and support keep
your machine up and running with limited
down time.
