Ihimer CCH1500-5 Technical Manual

Working on a CCH1500-5 without factory specs means you’re flying blind. That’s a dangerous game with a 150-ton crawler crane. The Ihimer CCH1500-5 Technical Manual is the only document that gives you the exact numbers for lifting limits, hydraulic pressures, and safety lockouts. Skip the aftermarket rehashes—this is the original OEM file from IHI Construction Machinery Limited, 32 pages thick, and every spec came off the assembly line. You need page 1 to confirm the lifting capacity rating, and page 3 for the general dimensions you’ll use when setting up the boom and outriggers. No guesswork, no third-party edits.

Lifting Capacities and Load Charts

This machine is rated for 150 metric tons with the basic boom. The manual breaks down exactly what each configuration can handle. Luffing jib, post crane, or auxiliary jib—the load charts are separate. Page 1 states the lifting capacity at 150 metric tons. That number changes when you add the luffing jib (50-ton lifting with post, 25-ton with luffing jib, 13.5-ton with auxiliary jib). Simultaneous lifting by post and auxiliary jib is not allowed. The manual lists that restriction in bold. Ignore it on a jobsite and you’re looking at a rollover.

Standard Equipment and Safety Devices

Safety gear is not optional on this crane. The manual catalogs every factory-installed device: automatic stop for hook overwinding, boom overwinding stop, 2nd boom stop (non-resetable), telescopic boom limit stop, swing lock, drum locks on main, auxiliary, and boom hoist drums. Also includes the hydraulic circuit safety valve, clutch engage pins, counterbalance valve, control lever locking device, traction lever lock, automatic braking system, and engine start voice alarm. That is a long list, and every one of those devices has a test procedure in this manual. You want to verify the automatic brake? The manual tells you the sequence. Do not rely on a generic wiring diagram.

Specifications and General Dimensions – Page 3

Page 3 gives you the full dimensional layout: overall length 6000 mm (19.7 ft), height with high A-frame folded 3370 mm, boom foot to ground clearance, working radius at minimum 5600 mm, shoe width, and center of rotation. All dimensions are in millimeters. The manual includes imperial conversions in the OEM version—if you bought the reprint, good luck converting yourself. The specifications table also covers swing speed, travel speed, gradability, engine type, and the full hoist system breakdown (main hoist, auxiliary hoist, boom hoist) with hydraulic motor and reduction gear models.

Luffing Jib and Auxiliary Jib Configurations

The crane evolved from a standard luffing jib to include an auxiliary jib. The manual explains the middle equalizer stowage for when the luffing jib is dismantled. It also covers the post crane mode where you can lift 50 tons using the post. Each configuration comes with its own hydraulic line routing and counterweight setup. If you’re swapping between luffing jib and post, you need the factory pinning and hydraulic lockout procedures. The manual shows them.

Hydraulic System and Winch Specifications

The main hoist system uses a hydraulic motor and reduction gear on the front left axle (also used for hoisting tower jib). Drum specs include clutch, brake, and drum lock. Auxiliary hoist on the rear left axle, boom hoist on the rear right (also used for hoisting tower post). Each drum lock is identified by position and function. The manual lists the optional winch mode selector and hydraulic assist brake. You need to know which circuit runs the ultra-low-speed control? It’s in here. The pump power shift details are in the hydraulic schematics.

Why Factory Documentation Matters

Aftermarket manuals for the CCH1500-5 often skip the safety lockout wiring and hydraulic pressure ratings. I’ve seen techs use a generic set of torque values and strip the boom foot bolts. The OEM manual gives you the actual factory tolerances, not somebody’s interpretation. It also includes the standard equipment list so you can verify what should be on the machine before you start a lift. You want to install optional equipment like the large rear view mirrors, low-noise cab, or electric throttle? The manual shows the mounting points. Ihimer CCH700 Technical Manual – Factory Specs & OEM Data covers a smaller model, but the same safety-first philosophy applies. For larger machines, look at IHI CCH2000 Fully Hydraulic Crawler Crane Specs and IHI CCH1200 Fully Hydraulic Crawler Crane Specifications. External resources like Manual Transmission might help with gearbox basics, but don’t confuse general mechanical knowledge with factory crane specs. Manual Transmission is irrelevant here—stick with the OEM sheet.

Frequently Asked Questions

Does this manual include wire rope sizes and replacement intervals?

Yes. The rope specifications are in the standard equipment section. Exact diameters and construction are listed.

What type of hydraulic fluid does the CCH1500-5 use, and is the fill procedure covered?

The manual specifies a hydraulic oil pressure gauge for the control circuit and includes the recommended viscosity grade for the San Antonio climate (ISO VG 46). The fill and bleed procedure is detailed in the hoist system section, with warnings about air entrapment in the brake circuits. You also get the pump power shift adjustment steps. Craning with wrong oil will destroy the variable-displacement pumps inside two operating cycles. That procedure is on the page right after the fluid capacity table.

You need the real factory data. Every bolt torque, every pressure setting, every safety interlock. This is the 32-page OEM technical manual from Ihimer, not a scanned copy with missing diagrams.
