Product concept of ZX-7

Increased fuel efficiency reducing running cost First-class operator comfort and increased versatility

Various improvements enhancing maintainability

The ZX-7 series has been developed with the owner and operator in mind.

For the owner we can provide added value by lowering his TCO. And for he operator we focused on his comfort in the cabin and the ability to adjust machine settings easily, depending on application requirements.

In addition the outer appearance is reinforced with a new strong design.

Vertical C pillars provide a rigid, tough impression and emphasize on the large cab space

A sharp lid design joining the cab and the rear body

A silver accent symbolizing its high quality

Large reflectors at the counterweight

Rigid: A powerful cab outlook is realized by emphasizing straight lines and edges.

Clean: Silver lines, a symbol of the high quality and technologies, are inherited from ZX-3.

Impressive: Graphical design stands out the machine among the conventional machines.

Oil pressure loss occurred since the pressure oil flown to center bypass was discarded into the tank.

Only required flow amount was able to be output from the pump by closing cut valve at half lever operation and oil pressure loss was reduced.

Oil pressure loss at half lever operation was reduced and fuel consumption was improved.

Urea SCR system (corresponding to EU Stage V regulations)

Stage V is currently achieved by using a combination of urea SCR (Selective Catalytic Reduction), DOC (Diesel Oxidation Catalyst), and CSF (Catalyzed Soot Filter). The amount of Urea water is roughly 2 to 3 % of the total fuel amount.

Maintenance inspection for CSF is required every 8,000 hours (instead of 4,500 hrs in ZX-5B) and CSF needs replacement only if necessary.

Air intake parts

By adopting PCV (Positive Crankcase Ventilation) closed engine for ZX-7 engines, the blow-by gasses are no longer leaked into the atmosphere but circulate in the air intake system. For this reason, the hoses have been changed to rubber hoses. Rubber hoses are strong to withstand oil, as the exhaust gasses contain oil vapor.

The Auto shut-down feature causes the engine to automatically slow down and stop after the pilot control shut-off lever is raised (locked) and some time has elapsed (indicated on the monitor). This is an effective way to save fuel, and reduce noise, exhaust emissions, and CO2.

Note: When the engine halts because of Auto Shut-down, the ignition will still be switched to ON. To re-start the engine, first switch the ignition to OFF, and then re-start.

Combining the use of the Auto-idle and Auto shut-down feature offers further benefits in preventing the waste of fuel.

Structure for protecting against falling and flying objects

OPG

ISO 10262

Operator Protective Guards This standard is specific to hydraulic excavators and stipulates ‘top guards’ and ‘front guards’. A ‘top guard’ is a structure designed to protect against objects falling toward the operator’s head. Energy absorption is set at Level I: 1,365J and Level II: 11,600J. This means that the protective structure entity will not penetrate into the DLV even when these amounts of energy are applied.

A ‘front guard’ is a structure designed to protect against objects flying toward the operator from a frontal direction. Energy absorption is set at Level I: 700J and Level II: 5,800J. This means that the protective structure entity will not penetrate into the DLV even when these amounts of energy are applied.

Structure for protecting against tipping or rolling

ROPS (ZX490)

ISO 12117-2

Roll-Over Protective Structures This is a standard for hydraulic excavators with operating weight of 6 to 50 tons, and is a structure that is meant to ensure that a deformed cab will not penetrate into the DLV even in the event of a rollover.

TOPS (ZX490)
