New Holland Kobelco CK800-III Technical Manual

I’ve pulled wrenches on enough heavy iron to know that guessing on a crane’s specs will get somebody hurt. The New Holland Kobelco CK800-III Technical Manual puts the factory data in your hands – not a third-party reprint. 32 pages of what Kobelco intended, not what some parts house thinks you need.

CK800-III Specifications: What You Get in These 32 Pages

On page 1 you’ll find the max lifting capacity: 80 US tons (160,000 lbs) at a 12-foot operating radius with a 50-foot boom. That’s not a marketing number – it’s the working limit. The manual gives you the full load chart context so you don’t overload the machine. Page 3 lays out the Hino JO8E-TM diesel engine – 213 HP at 2,000 rpm, 588 lb-ft of torque at 1,600 rpm. Displacement is 469 cubic inches, six cylinders, EPA Tier 3 compliant. If you’ve ever had to order a rebuild kit for a Hino, you know how critical exact bore and stroke are. This manual has them: 4-13/32″ bore, 5-1/8″ stroke.

Engine and Powertrain Details from Page 3

That engine section on page 3 covers the cooling system – corrugated core radiator with thermostat control. The air cleaner is a dry type with replaceable elements. The manual doesn’t skip the electrical system either: 24-volt starter at 5.0 kW, 24-volt 60-amp alternator, and two 12-volt 136 AH batteries wired series. If you’re chasing a charging problem, those specs are where you start. Unlike a standard Manual Transmission that you’d find in a truck, this crane uses a hydraulic drive system. The manual gives you the travel speeds – 1.18 mph high, 0.75 mph low – and line speeds for the hoist drums: 390 ft/min maximum, controllable down to 10 ft/min via the dial-type speed control.

Working Speeds and Load Control

Hoist and lowering line speeds for both front and rear drums are listed: 390 to 10 ft/min. Boom hoist and lowering line speeds are 230 to 7 ft/min. Swing speed is 4.0 rpm. These numbers aren’t just for show – they determine the safe working envelope. The manual also includes ground bearing pressure at 11.3 psi and gradeability of 40%. If you’re rigging this machine on a jobsite, you need those figures to avoid sinking or tipping. I’ve seen operators rely on aftermarket charts that round up the gradeability – that’s a lawsuit waiting to happen.

Why Factory Documentation Beats Aftermarket

Aftermarket manuals for the CK800-III often pull specs from one machine and apply them to another. Kobelco changed the carbody design between the CK550 and the CK800-III. A KOBELCO CK550 Technical Manual Specifications won’t give you the correct rear-end radius or counterweight ground clearance. The factory manual is the only source for the exact center-of-rotation-to-boom-foot-pin distance of 3′ 7″ and the height from ground to boom foot pin of 5′ 9″. If you’re rebuilding the swing circle or replacing the boom, those dimensions are non-negotiable. The lifting capacity is rated at 160,000 lbs – not a pound more – and the factory manual makes that clear.

Who Needs This Manual?

If you’re a crane mechanic, rental yard operator, or heavy equipment owner – you need this. The manual covers the entire crawler crane: dimensions, working speeds, upper machinery, and the power plant. You don’t need a full shop manual for every system; this is a technical manual focused on operational specs and maintenance data. Pair it with the New Holland Kobelco CKE1350 CK1600 2004 Technical Manual if you have a mixed fleet, or the New Holland Kobelco SK75 SK500 Technical Manual – Factory Specs for excavator work. For transport, you might also refer to a Manual Transmission reference if you’re towing with a conventional truck, but this crane’s travel is self-propelled.

Frequently Asked Questions

Does this manual include torque specs for the undercarriage?

Page 3 gives the track shoe width, overall crawler dimensions, and ground clearance. Specific torque values for track bolts are not listed in the 32 pages – this is a technical manual focused on machine specs, not a service manual. You’ll need a separate service manual for fastener torque.

Is this the same as an operator’s manual?

No. This is a technical manual – specifications only.

Stop trusting internet forum numbers or faded photocopies. The factory data is the only thing I trust when a 160,000-pound crane is on the hook. Access the Factory Manual and get the real specs – your crew’s safety depends on it.
