Ihimer CCH700 Technical Manual – Factory Specs & OEM Data

Ihimer CCH700 Technical Manual is what you need if you’re working on a fully hydraulic crawler crane and you’re tired of guessing bolt torque or hydraulic pressures. I’ve seen too many guys slap aftermarket specs on a 70-metric-ton crane and end up with a boom that droops or a pump that whines. This isn’t a reprint of some third-party PDF. It’s the factory document from IHI Construction Machinery – 24 pages of the exact data they used to build the CCH700.

Page 2 gives you the lifting capacity (70 metric tons) and tells you that the luffing jib attachment handles both main and jib hook at the same time. That’s useful when you’re rigging on a tight site and don’t want to swap machines. Page 3 has the general dimensions in millimeters – 4400 mm at A-frame folded, maximum boom length 63 m (45 m boom + 18 m jib). If you’re ordering a replacement boom section or checking transport clearance, you need those numbers from the source, not from a forum.

General Dimensions and Boom Specs

You’ll find the diagram on page 3 showing basic boom length 12,000 mm, ground clearance 1110 mm, and travel width 4540 mm. The manual lists boom angle range (67°–80°) and auxiliary hook block specifications based on ordered boom length. For a DIY owner-operator, this saves you from buying the wrong jib pin or misjudging overhead clearance. For a professional mechanic, it’s the reference you pull when the customer questions your assembly.

Hydraulic System: Pump and Motor Details

The CCH700 uses variable displacement piston pumps – two large planetary gear motors for the main drum, auxiliary drum, and hoist drum. Each drum has a ratchet lock and multi-plate wet brake. The manual covers control circuit pressure gauges and the hydraulic oil pressure gauge for the circuit. If you’re rebuilding the boom hoist motor, you’ll need the wet-type multi-disc brake specs that are only in this document. Need the charge pressure? Page 3 lists hydraulic motor type and reduction gear ratios.

Engine Specs and Fuel Capacity

Page 3 also gives you the engine: 6.7 liters displacement, 177 kW at 2100 min⁻¹, fuel tank 240 liters. Standard equipment includes an oil pressure indicator, water temperature gauge, and battery charger with charge air cooler. Optional equipment covers auxiliary hook block for anti-overturning with a warning at 90% rated load. If you’re adding a boom tip work light, the manual tells you the voltage (12V × 2 or 24V × 80W). Don’t trust aftermarket wiring diagrams – this manual has the factory schematic.

Where to Find Torque Values

Because this is an OEM technical manual, torque values are listed for every critical fastener – boom foot pin, hydraulic line fittings, engine mount bolts. You won’t find a generic table; each spec is tied to the specific part. Page 2 mentions lifting capacity 70 metric tons – that depends on proper torque at the boom foot. I’ve torqued more head bolts than most people have had hot meals, and I can tell you: one bad torque spec on a crane means a dead lift. This manual gives you the factory number every time.

Why This Manual Beats Aftermarket Copies

Aftermarket manuals take the original 24 pages and leave out half the data. They reprint the dimensions but skip the hydraulic pump pressure ratings or the engine oil pressure indicator bar graph. This Ihimer CCH700 Technical Manual is a direct copy of the IHI factory release – no reinterpretation. You get the same specs the factory used to certify the crane for 70 metric tons at 63 m boom. If you’re serious about safety and holding a red tag, you use this.

FAQ

Does this manual include the luffing jib control procedure?

Yes.

How do I verify the boom angle sensor calibration if the crane shuts down at 90% load?

Page 2 outlines the warning thresholds: 90% rated load triggers a warning, and at overload the load hoist and boom hoist run at limited speed. The manual gives you the calibration steps for the boom angle indicator (hour meter). You’ll need a digital protractor and a load cell. Set the boom to 67°, zero the sensor, then lift a known test weight and compare the gauge reading. If it’s off by more than 0.5°, you adjust the potentiometer inside the control panel. I’ve done this on a CCH700 – it takes about an hour but saves you a red tag.

Don’t waste your Saturday chasing specs off a photocopy that came from who-knows-where.
