CK850G-2 Hydraulic Crawler Crane

Max. Lift Capacity: 85 US Tons
Max. Boom Length: 200 ft.
Max. Boom + Jib Length: 180 ft + 60 ft

The Kobelco CK850G-2 Crawler Crane is designed from the ground up for reliable operation, convenient maintenance and easy transport. The CK850G-2 features a new engine that complies with the latest EPA Interim Tier IV standards. The cranes have also been designed with new energy saving assist systems known as the “G-modes”, which can achieve up to a 30% savings in fuel consumption. The “G-modes” include the auto idle stop system, energy saving winch control system, and the engine RPM limitation system. Other re-design features of the new G series includes: compact structure allowing for greatly improved transportability, larger cab design, LMI touch screen, counterweight detection device, improved counterweight self installation mechanism, and newly improved (short) control levers. Kobelco is renowned for smart engineering and an unwavering focus on creating the best value package for lifting solutions.

cab & controls

The G-series cab has been completely re-designed to give the operator’s better visibility, mobility, and a relaxed environment to enhance efficiency. The new cab design is on an isolated cab base frame which reduces vibration during crane operation.

Increased Cab Size
The increased space from 77.34′ to 109.5′, gives the operator more room in which to perform crane operations, also adding more leg room and a wider cab door for ease of entry.

Larger Front Glass
The cabs front glass has been increased up from 10.8′ to 11.7′, adding an expanded field of view which provides improved operating conditions, increasing safety and operability.

Controls
The repositioned and shortened levers, with easily held grips, allow for precise operation and ensures a smooth and consistent performance.

Kobelco knows that operator comfort is directly related to performance and has developed the ideal balance between comfort and ergonomics in the cab design.

UPPER MACHINERY

p-g-series-upper-machinery Kobelco’s drive and determination to build the best machine is visible throughout the very heart of our cranes.

Upper Frame
The upper frame is fabricated from all-welded alloy steel and is CAD designed for durable strength.

Innovative Wet-Type Disc Brake System
Kobelco’s oil cooled wet-type multi-disc brake system provides quiet, dependable braking power. Multiple discs are self-adjusting and self equalizing, minimizing maintenance requirements. Forced oil circulation keeps brake temperatures cooler during long, continuous operations and maximizes smooth brake operation. The completely sealed system eliminates the possibility of outside contamination, providing years of problem-free service life. The low brake pedal effort reduces operator fatigue when machine is working in the free-fall mode.

Incredibly Strong Winches
The powerful winches boast a rated single line pull, reducing the number of parts of line involved and improving hoisting speed. The result is dynamic lift and continuous trouble-free operations.

Large Capacity Drums
Kobelco’s innovative internal disc brake system allows for the use of full functioning drums, reducing the chance of uneven winding, while extending the service life of the wire rope. An optional third drum is full functioning as well, allowing for more attachment options and better operation coordination.

LOWER MACHINERY

One Tough Machine!
Kobelco Cranes feature an all-welded, high-tensile strength steel carbody, manufactured in a single piece using the latest CAD technologies for unmatched rigidity. The crawler assembly consists of an idler wheel, lower rollers, the travel motor assembly, upper rollers, and flat shoes on each side.

On-Site Maneuverability
Independently driven hydraulic travel motors with planetary reducers provide three steering modes for optimal on-site maneuverability. In addition to conventional skid steering, the independent crawler drive enables counter-rotation of the tracks as well as differential track speed steering. Travel motors are less than track shoe width, protecting them from damage.

Self-Erecting and Transportation
Kobelco has designed the structure of the G-series making all models more compact and efficient loading and unloading for transportation. The G-series cranes also have an improved counterweight self installation mechanism, counterweights are stacked on the ground and lifted by vertical cylinders for installation – this is for all G-series models.

HYDRAULICS

p-g-series-hydraulics Kobelco has improved an innovative full hydraulic system for the cranes. It performs all crane operations including load hoist, boom hoist, swing and propel operations, free-fall, as well as counterweight and crawler frame installation and removal. The hydraulic circuit can be either a dual pump flow or a single pump flow, so that the circuit can be adequate for all job applications – this can be switched to choose the best circuit for your job application.

Single Pump

Allows the winches to be controlled independently.
- Luffing

Dual Pump

Maximizes the speed in single line operation.
Synchronizes the speed in double line operation.
- Steel Erection
- Bridge Work
- Clamshell
- Piledriving

MAINTENANCE

Tough, Maintenance-Free Durability
Careful attention has been paid to every detail of design so that the Kobelco crane stays on the job, not in the shop. Routine checks can be conducted easily with the help of service compartment doors that provide full access to the engine and hydraulic components. From the wet-type disc brake system to the easy-access engine layout, the Kobelco crane is one of the easiest machines in its class to maintain:

Double-tapered connecting pins for base boom.
Cast iron rollers and idler sprocket are lubricated and sealed for long, trouble-free service.
New machinery layout simplifies engine checks and routine maintenance.

Simplified Maintenance
The disc brakes require no brake lining replacement or adjustment for simple maintenance. Also, a new engine layout on the side of the machine provides easy access for routine inspections and servicing.

G-MODES

G-Mode
The G-mode is an exclusive energy and fuel saving system, up to 30% in fuel savings. The G-Mode eliminates needless operations and engine functions allowing for reduced fuel consumption by using three basic modes that are all operator selectable.

Auto Idling Stop Mode (AIS) – The AIS mode can conserve fuel by stopping the engine, with an operator prompt, after 10 seconds of idling time. Restarting the engine is simple by just twisting the accelerator grip.
G-Winch Mode – The G-winch mode can produce maximum winch line speed at a low engine RPM.
G-Engine Mode – the G-Engine Mode limits maximum engine speed to 1,750 RPM and controls the pumps to make engine operation in the most efficient condition.
