Kobelco SK210 Pump Problem. Discussion in 'Excavators' started by PRDiesel, Apr 29, 2009. Kobelco pump that machine has two solenoids one for each half of the main pump check the one on the second half of the pump kobelco numbers them from the engine out the solenoids do go bad we have changed a few of them but we have several thousand.
The “G-modes” include the auto idle stop system, energy saving winch control system, and the engine RPM limitation system. Other features of the new G-2 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. The G-series cab gives the operator better visibility, mobility, and a relaxed environment to enhance efficiency. The cab design is on an isolated cab base frame which reduces vibration during crane operation.Increased Cab SizeThe 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 GlassThe 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. Kobelco’s drive and determination to build the best machine is visible throughout the very heart of our cranes.Upper FrameThe upper frame is fabricated from all-welded alloy steel and is CAD designed for durable strength.Innovative Wet-Type Disc Brake SystemKobelco’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 WinchesThe 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 DrumsKobelco’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. One Tough Machine!Kobelco Cranes feature an all-welded, high-tensile strength steel car body, 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 ManeuverabilityIndependently 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.
Kobelco has improved an innovative full hydraulic system for the cranes. It performs all crane operations including load hoist, boom hoist, swing and propeloperations, 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.
Tough, Maintenance-Free DurabilityCareful attention has been paid to everydetail of design sothat 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-accesseng 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 MaintenanceThe 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.Find the Kobelco Crawler Crane dealer nearest you. Kobelco has designed and warranted a 12″ touch panel screen with sunshade and screen protector. This intuitive and easy to understand new touch screen monitor gives the operator a full display of essential data. Universal pictograms are used providing easy visual recognition, making this new technology easy to read and understand the information.
This new monitor includes: Hook Height, Wind Speed, Engine Speed, Display Lamp of standard functions, Gauges, Over-Swing Prevention Device, Switches, and Error Messages.
