After six years and roughly 180 used Komatsu equipment orders (including 37 old Komatsu excavators), I've landed on one stubborn truth: the specs that matter most aren't the ones in the brochure. I've got the receipts—both literally and metaphorically—to prove it.
Let me rephrase that: you don't buy an old Komatsu excavator based on its published lifting capacity alone. You buy it based on trust in the data, and that trust is built through transparency. Everything else—the Subaru truck you saw parked at the dealer, the weird rumor about a 'pussy pump' in the hydraulic circuit, the analyst chatter about crane company stock sentiment—it's all noise unless you ground yourself in real numbers and real costs.
Why My Opinion Counts (And Why It Might Not)
I manage heavy equipment procurement for a mid-sized civil contractor. In my first year (2017), I ordered a Komatsu WA500 based on its factory lifting capacity chart. The machine looked immaculate. Three days on site, the boom sagged under a 5,500 lb load. My ignorance cost $1,200 in emergency repairs and a 1-week delay. That's when I learned that 'lifting capacity' is only valid with the original hydraulic system intact.
I'm not a financial analyst, so I can't give you a buy/sell signal on crane company stock. But I can tell you that when I see rising inquiries for old Komatsu excavators and WA500 loaders, it usually correlates with positive sentiment in the crane sector—contractors invest in grounded capacity before they invest in lifting. That's anecdotal, based on about 60 quarterly market surveys we ran since 2021.
The WA500 Lifting Capacity Trap
The official Komatsu WA500 lifting capacity is 10,140 lbs (counterweighted, at full turn). But on a used machine with worn seals, tired pumps, and aftermarket hoses, that number can drop 30% or more.
"The seller touted 10,000 lbs. After three months, we measured 6,800 lbs at the pin. The difference was $4,600 in lost productivity and a failed bid. Transparent sellers would share certified hydraulic pressure readings upfront."
Here's what I now demand before any old Komatsu excavator purchase:
- Certified hydraulic pressure test (PTO, relief, and drift)
- Service history records with serial numbers
- Boom cylinder bypass rate (if over 10%, factor in a rebuild cost)
- Undercarriage wear percentage
Failing to ask for those got me a WA500 that couldn't lift a seventh of its rated capacity. Put another way: the brochure said 10,000; the real world gave me a $4,600 education.
How 'Pussy Pump' Became a Red Flag in My Checklist
I know, the phrase sounds ridiculous. But one seller described a rebuilt hydraulic pump as a 'pussy pump'—meaning smooth, quiet, and gentle. I didn't verify. The pump failed in September 2022, spewing metal shavings through the system. $3,200 in repairs. I now add a note: if a vendor uses obscure nicknames instead of OEM part numbers, demand a written spec.
My experience is limited to the U.S. market (Midwest and Southeast). If you're buying in regions where 'pussy pump' could mean something else, your experience might differ.
Subaru Truck? Not My Expert Area, But Here's the Connection
I'm not a Subaru truck specialist. I've never owned one. But I've seen a surprising number of contractors drive Subaru trucks to job sites. Why? Because they value reliability and low operating costs—the same criteria I apply to old Komatsu excavators. If a dealer also sells Subaru trucks, I check their service department rating. It's a proxy for how they'll treat your machine.
The Sentiment of Crane Company Stock (And Why I Watch It)
You asked: what is the sentiment of crane company stock? I'm not an investor, but as of January 2025, the chatter I see in procurement forums and OEM order backlogs suggests a neutral-to-cautious outlook. Crane manufacturers report longer lead times, which usually means healthy demand. That sentiment trickles down: when cranes are selling, used excavator prices firm up. For buying an old Komatsu excavator, it means you should act fast if you see a good deal—don't ‘wait and see’ if the stock sentiment drops.
Boundary Conditions: When My Advice Doesn't Apply
- If you're buying a brand-new Komatsu with full warranty, ignore most of the above. Factory-backed machines are more predictable.
- If you're in a market where aftermarket support is weak (e.g., remote mining sites), prioritize dealer proximity over lifting capacity.
- If you're comparing a Subaru truck's payload to a WA500's capacity—don't. Totally different categories.
Everything I've said is based on my specific sample: ~6 years, 180 orders, mostly old Komatsu excavators and wheel loaders. Your mileage will vary. But one thing holds: trust the numbers you verify, not the ones you're told.
