SkyTrim
is manufactured by Kershaw, a division of Progress Rail
now a Caterpillar company.
Financing
available through a Caterpillar company.
- Repowered
with a CAT C4.4 127 HP 4-cylinder, 4.4L, turbocharged, charge-air-cooled,
water cooled, full muffler system, EPA Tier 3 compliant.

- Cab
was widened 4" to accommodate the operator's console. The
console is completely inside the cab to eliminate the need for
an extra sliding window to access the control box. This console
includes an electronic engine throttle control as well as SAE
J1939 Engine Diagnostics display for monitoring the engine parameters.
The console also features a hydraulic temperature gauge for convenient
diagnosis of hydraulic cooling issues. The saw on/off control
is an electric safety switch mounted on the console. This switch
operates a solenoid operated hydraulic valve outside of the cab
thus removing additional hydraulic fluid from the operator's cab.

- Engine
compartment expanded for easier access to pumps and other components.
- Improved
hose reel cover. Larger and made from ¼" steel plate.
- Hose
rollers design improved. Rollers made from 2" diameter UHMW.
Pins have full welded heads and square stock added to tilt frame
to prevent pins from turning and wearing into tilt frame structure.

- The
seat base in the operator's cab is adjustable and has three positions
to best suit the operator's needs. The base can be adjusted between
0, 5, and 10 degrees of rearward tilt to offer the operator a
more comfortable position for viewing limbs during trimming operations.
|
| |
- Boom
cradle and boom up/down cylinder pins now feature tapped holes
in the heads for use with slide hammers to aid in removal.
|
- Larger
diameter pulleys on rear of boom drive assembly to improve hose
feeding and to prevent wear and tear on hoses and pulleys.
|
|
- Saw
frame weldment material has been increased, as well as stiffeners
added for more robust design and improved longevity.
|
- Broom
drive mount redesigned so that the diverter valves are lying flat
to prevent build up of debris and water on the valve end caps.
Diverter valves are redesigned to add a brass collar inside the
valve to prevent spools from sticking.
|
|
- Tilt
frame has added large access openings in the side for improved
mechanic access for maintenance and repair work. Large control
valvebank is repositioned to have better access for adjustments
and plumbing repair work.
|
- Boom
drive motion control valve has changed. We're using a manifold
mount block that bolts directly to the boom drive motor. This
eliminates the troublesome short hoses on previous design. We
also changed the valve to ductile iron instead of aluminum to
eliminate any possible problems with expansion and contraction
of the aluminum blocks.
|
|
- Cab
has added front access panel for accessing hydraulic plumbing
for foot pedals.
- Electrical
enclosure has been updated with standard automotive fuses for
easy field repair and readily available automotive parts.
|
- The
boom drive now utilizes an overhung load adapter to support the
massive side loads developed by the boom drive chain system. This
will improve shaft seal life in the motor itself, as well as eliminate
failures of motor shafts themselves. The boom drive sprocket is
redesigned to utilize a taper lock bushing system. This will positively
lock the sprocket in place on the shaft so that it cannot move
or come completely off of the shaft during operation.
|
|
- Improved
heating and cooling in the cab. Changes as a whole will improve
the heating and cooling capabilities of the operator's cab. To
aid in cooling, the following changes were made. Removing all
high pressure hydraulic oil from the cab will drastically reduce
the heat load inside the cab. Saw, plow, and winch plumbing removed
from the cab completely. Steering reduced to pilot pressure lines
only. Foot pedal plumbing inside enclosure that is separated from
operator's compartment. Pilot lines route through bulkhead fittings.
This eliminates the large opening and allows for a more complete
seal on the cab structure. The LH sliding window has been removed
since the control panel is inside the cab. This will aid in sealing
up the cab also. Removing large openings and the sliding window
will greatly increase the ability to heat the cab to a comfortable
temperature.
|
- Keeper
bolts on all thread rods on boom drive assembly were increased
in size to 3/8".
- Boom
stop rocker arms are redesigned and repositioned to improve longevity
of these components.
|
|
| |
-
Plow, winch, and steering functions are now all pilot operated
for smoother operation. The plow/winch controls are mounted such
that the plumbing is entirely outside of the cab. Plow/winch controls
moved to new location conveniently located in front of the operator
to improve ease of operation. All hydraulic functions in the cab
are routed through bulkhead fittings in the cab floor to better
seal the cab for cooling purposes.
