Non-bentonite fluids have their
limitations; QUAD POWER or any
polymer drilling product, alone,
should never replace bentonite-based
drilling fluids for larger-diameter,
longer-bore shots or exceptionally
challenging and high-risk projects.

Ditch Witch, a Charles Machine
Works Company, introduced several
underground construction products
and solutions.
The newest evolution of its
directional drills, JT 24 is powerful
- with a 101-gross horsepower, Tier
4- and European Stage 5-compliant
Cummins diesel engine and 24,000
pounds of thrust and pullback - while
minimizing its footprint in a wide
range of urban and residential gas,
fiber and other utility installations.
A new hydraulic platform utilizes
leading technology to maximize
drilling efficiency and conserve
horsepower for where it matters
most - downhole.
With a class-leading maximum
carriage speed of 216 fpm, the
machine enhances job-site
productivity by decreasing cycle
times and increasing uptime. It also
holds up to 400 feet of drill pipe
onboard, allowing for longer bores
and increasing return on investment.
The RT80 ride-on trencher
features a compact design that makes
it ideal for heavy-duty trenching,
vibratory plowing and microtrenching
in confined urban and residential
areas, where larger machines can't
maneuver as freely. The machine is
also built to adapt with a modular
design that allows tires and tracks to
be easily interchanged in the field -

keeping work going smoothly.
The RT80 trencher is equipped
with a 74.5-horsepower Deutz®,
Tier 4 diesel engine, a static load
rating of 35,407 pounds and a
wide-axle rating of 39,000 pounds.
It's also built for efficiency with
a three-speed, shift-on-the-fly
ground drive system that allows
operators to set the correct range
without stopping work.
As the largest and most powerful
unit in the Ditch Witch family of
stand-on skid steers, SK3000 features an operating capacity of 3,100
pounds - 50-percent more than its
closest competitor. The unit delivers
5,500 pounds of breakout force to
help operators lift and move heavy
loads with a bucket. It also directs up
to 51 horsepower to the attachment
- more than any other machine in its
class - for efficient and productive
use of hydraulic attachments.
Specifically designed for its AT30
directional drill, the new Ditch Witch
SwitchBack system helps operators
by reducing time to transition to
pullbacks, allowing a smaller exit pit
and improving productivity, since
the amount of time needed to dig a
larger exit pit and swap tooling can
add up to an extra day to a job in
rock conditions.

equipment and operators onsite to
lift and load the reel, as on a fixed
reel trailer.
The hydraulic payout/take-up
assembly is a sealed-gear-driven
unit. Keeping repair work to a
minimum, there are no chains or
sprockets to break or wear out.
The drive unit is exceptionally
smooth and quiet to operate, easily
engages and disengages from the
reel bar. Not only does it payout
and retrieve, but options hydraulic
brake tensioning eliminates the
heat generated by traditional caliper
and rotor. This reduces line gallop
and allows for a longer tensioning
duration. The generated heat is
absorbed in the hydraulic oil and
dissipated by the oil cooler.
This unit comes standard with
an onboard hydraulic power supply.
Felling uses a Honda GX 390 gas
engine with electric start and recoil
backup. The power pack is equipped
with a 25-gallon hydraulic reservoir,
a hydraulic oil return filter and a
lockable theft-resistant enclosure.
The FT-14-2 R Turret is rated for
2,250-psi continuous and 2,900-psi
maximum and provides 8 gallons
per minute.

R35Z-9A compact excavator's
standard features include a Werk
Brau-compatible thumb bracket,
a diverter valve for easy switching
between a thumb or attachment;
pin-grabber style, dual-locking quick
coupler and Q/C piping; enhanced
bucket design with lifting-eye and
two-piece tooth design for easy
replacement; and a durable centered
boom LED work light for improved
job-site illumination.
Another in the 9A series compact
excavators, the 6-ton R55 is the
only one to feature a standard
counterweight design for maximum
lifting power and balance. It's
a popular choice among utility
and underground construction
contractors for its combination of
power and maneuverability.
Hyundai also unveiled the
prototype of a fully electricpowered compact excavator, R35E,
developed in collaboration with
Cummins Engine Co.
Powered by eight Cummins
BM4.4E flexible battery modules
(4.4 kWh each) connected to
produce total energy of 35 kWh,
R35E provides enough power to
operate the machine for a full work
shift and charge in under three hours.
The machine eliminates all gaseous
emissions and substantially reduces
noise, making it ideal for use in urban
and suburban construction.

Felling Trailers' Self-Loading Turret
Reel trailer, has a 360-degree
hydraulically operated rotating turret
assembly that can lock into any
position when the directional control
valve is released. Keeping mindful of
equipment, time and operator safety,
the FT-14-2 R Turret's self-loading
feature eliminates the need for extra

Among the nine machines exhibited at the Hyundai Construction
Equipment Americas booth was the
HL940TM wheel loader, one of two
Tool Master models in its HL900 series product line. The parallel linkage
in this 15-ton model's Tool Master
boom design increases lifting capacity, improves load stability, speeds
dumping and enhances visibility.
