This is the story of the Shovel
Logger that could . . . . . . that could be built and delivered in seven months
instead of the usual three- to four-year development cycle. . . .that could be
designed, spec by spec, from notes on the back of a business card. . . . that
could be the fastest shovel logger in the Pacific Northwest, handling steep
hillsides and increasing productivity by 20 to 25 percent. Not bad for a shovel
logger that was only a wish list of specifications, in the hands of Simpson
Timber's logging manager Jerry Barnhart and maintenance supervisor Roy Meier at
the 1999 Oregon Logging Conference.
The journey began when Roy, in
charge of maintenance at Simpson's Camp 1 Shop, told Jim Stevens, the Chehalis,
Wash., Caterpillar sales rep for NC Machinery, that he was in search of a new
shovel logger. "We have three shovel logging sites and each has at least
one shovel logger," says Roy. "Two years ago, one of our shovel
loggers was destroyed by fire. It caught us by surprise, so in an emergency
purchase we had to buy the biggest machine we could to replace it and at that
time, it was a Cat 330." The results were less than satisfactory.
"We'd used the 330's as log loaders, but we hadn't used them as dedicated
shovel loggers," explains Roy.
As they ran the machine, they
discovered that in a shovel logging application, the 330 had its limitations in
terms of production. The operator had to work a lot harder to get the same
amount of wood out as he did with his older machine and there was accelerated
wear on the machine. During that time, Roy was going to logging shows to see
what was new in equipment. The information he got from Jim Stevens was that Cat
was looking at producing a bigger machine than a 330, but it's going to be two
or three years down the road. Roy knew he didn't have that kind of time.
"We're using our machines 2,000 hours a year and they're wearing out and we
have to make a replacement decision. We couldn't wait, so the decision was going
to be based on the best machine available to meet our needs and at the
time."

And it wasn't going to be a Cat.
"I guess Jim was able to stir enough fires and there were enough requests,
Cat started looking at it more seriously," recalls Roy. The conversation
continued a few weeks later at the 1999 Oregon Logging Conference. Over dinner,
Roy, Simpson logging manager Jerry Barnhardt, Jim and some Caterpillar
executives, including Dan Benz, product group manager with Caterpillar's World
Wide division, started talking about Simpson's dream machine. "That's where
I met Dan Benz, he's in charge of all their [Caterpillar's] forestry product
division and the excavator manufacturing," says Roy. " He asked me
what we were looking for in a shovel logging machine.
I noticed he was writing
everything down on the back of a card. He told me they were going to make an
effort to put something out, and they'd stay in touch." Roy was skeptical.
"Sometimes when you're working with a large corporation, you meet a lot of
guys at different levels and they'll tell you stuff, but nothing ever happens. I
was thinking this was another deal like that. Lo and behold, a couple months
later, Jim Stevens came back and said they were developing a price for it and
they were going to have it put together." Jim Stevens says, "It was a
lot faster response time than in the past because Cat's opened up their forestry
division and wants their share of the market in forest products." And
because Cat already had the existing class machine in 345 as an excavator, which
teamed up with Jewel on the boom also cut development time. "We talked in
February and they had the machine assembled for the Kelowna Log Show in
September, six months later," says Roy. "After that, I was a
believer."
Making the decision
Ultimately, Simpson made the decision to go with Cat for several reasons.
"If you invest that much money in a machine and you can't get parts for it
and you can't get it fixed, it loses a lot of its value to you," explains
Roy. "The other driver is that we try to keep things standardized and we
already have six 330 Cat log loaders, and the rest of them are 235s, so we had
no non-Cat machines, and we wanted to keep that so we'd have just one source for
parts and service. Cat's going to be financially strong enough to stay in
business - that was a big driver." Roy also had a concern over price:
"If Caterpillar was going to make a machine of that size, I was a little
hesitant if they were going to be able to compete on a price level, but they
came right in there." Building the specifications Caterpillar's shovel
logger prototype was delivered complete, meeting or exceeding all the items on
the Simpson "wish list", including: o Ground clearance of 36 inches
for speed, maneuverability, and environmental friendliness o Dual swing drive
for increased speed and productivity. o A 48-foot boom, enabling it to grab 10
to 15 percent more in length. o A bigger size track-and-rail assembly. o
Removable swing frames. o Track width of 13 feet, outside to outside, for added
stability. o Track guards.
Based at Camp 1
Today the 345-B shovel logger makes its home base at the Camp 1 Shop in Shelton,
Washington. "There's two different types of logging here," says Roy.
"One is fell and buck where the cutter cuts the tree down and actually cuts
a tree into segments in the woods. The other type is tree-length, where we have
a mechanical faller or a hand cutter just cut the whole tree down. This is the
first machine that's really excelled at tree-length because it has the swing
power to do it." Roy sees higher productivity with the 345-B - about 15
percent higher than the 330 for fell-andbuck, and closer to 25 percent higher
for tree-length. He notes, "We're tending to do more and more tree-length,
and this bigger machine and more productivity in treelength is the direction we
want to go. We've had some real surprises in units. We'll go through ahead of
time and estimate how many days a shovel logger will be in each unit depending
upon species of wood, the size of the wood, and type of terrain. We've found
this machine already has beat the schedule on quite a few of the units."
On the job
Steep slopes are where the 345-B's dual swing drive excels, providing additional
swing power so the operator can easily swing logs up hill. Roy notes that the
older machines like the 235s, and the smaller machines like the 330s, just don't
have the swing power to swing the logs up hill. Roy says, "Other benefits
we've seen is that the hydraulic performance is actually quite a bit faster than
we anticipated, which helps in making it so productive. It's not only the
physical measurements of the ground distance and the size of the components,
it's the speed involved too." Another feature Roy praises is the engine:
"The electronic engine has a fuel system fired by individual injectors, all
controlled electronically. The engine burns a lot cleaner, you don't see hardly
any black smoke coming out of it. It's more efficient. Compared to the old
machines, this machine can do more work, but it burns the same amount of
fuel." Another special part of the machine is the boom. Roy worked on its
design with Jewel. His top criteria? Performance. He recalls, "I kind of
threw commonality out the door. We could have had all the same cylinders. If we
would have done that, we would have hindered performance. Certain parts of the
machine you want strong cylinders that are slower. Other parts of the machine,
you want faster cylinders The 70-ton Cat 345-B shovel logger excels at
tree-length, increasing productivity by 25 percent. that aren't quite as strong,
but they give you the speed 'cause you don't really need the strength. So we
speced the cylinders for ultimate performance and threw commonality out the
door. I think it's paid off. We came out with a pretty hot machine. Knowing this
machine is probably a 20 to 25 percent more investment than the smaller machine
- I figured we better build it good the first time, otherwise we're not going to
buy anymore." Operator Randy Rakevich had the machine on a steep slope and
watching him operate it at full speed, swinging tree lengths as if they were
tinker toys, it was clearly a marvel of design that kept the machine from
tipping over. Randy grins at the observation. "You get used to the steep
ground, you learn what the machine will do, I'm still learning. The 330, on this
type ground, wouldn't be worth beans. I've been doing this for 17 years now -
it's quite a bit easier with this machine."

Partnership Works
Roy appreciates the speed with which Caterpillar moved to produce the 345-B.
"Somebody moved ahead after that dinner at lightning speed," says Roy.
"They found a guy who eliminated a lot of the hoopla and was able to get
this into development and out to us in seven months, which is an amazing time.
They have a division called Nexus, and they put this whole undercarriage frame
together. They built it up while the other guys were building the carrier and
the two came together about the same time. They had all the stuff there, it just
took somebody to get it organized. This worked out really well." What's in
the future? Simpson's second 345-B is currently undergoing some changes, as
Caterpillar replaces its 52-foot boom with the original prototype's 48-foot
size, which seems to work best. Roy says, "We're looking at a third machine
and it could be ordered next January." Obviously, designing the shovel
logger with the customer as a partner turned out well for both Simpson and NC
Machinery, and their 20-plus year relationship looks like it's off to a great
millennial start with the Cat 345-B shovel logger.
