SH240-5 Sumitomo excavator specs & Dimensions (2017 - 2026)

SP (Speed Priority mode)

SP 'Speed Priority' mode has been developed, which is not available in competitors models nor in our previous model. This will create biggest productivity in its class with more economical fuel efficiency even in comparison with the Heavy mode on our previous model. In addition, the throttle control is simple to use.

Mode Selection by Throttle

Mode selection by pressing the button in our previous model sometimes cause inconveniences for the operator. The throttle control system has been upgraded and the new system “A” mode which stands for “Adjustment Mode” now covers the 3 previous modes of ‘Auto, Standard and Light’. In addition there is “H” (Heavy) mode and “SP” (Speed Priority) mode, and the hydrostatic pump oil flow will be regulated automatically in each of the 3 modes respectively. The SP mode is added to the operation mode. Furthermore, the A (Adjustment) mode is added to the SP and H modes, respectively. In comparison with the H mode of Dash 3, the SP mode has reduced the fuel consumption by 12%, and the H mode of Dash 5 has reduced the fuel consumption by 18% as compared with Dash 3.

Engine

A newly developed ISUZU engine 4HK1X complies with Emission Regulations U.S. EPA Tier III and EU Stage IIA. This produces bigger output and torque, and far better fuel consumption than the previous model.

Cooled EGR System

The EGR (Exhaust Gas Recirculation) mixes exhaust gas, which is once exhausted, with the air intake that is taken in so as to lower the combustion temperature, thereby reducing NOx (nitrogen oxide). Adoption of a cooled EGR system, in which the recirculated gas is cooled in the middle of the re-circulation, preempting a decline of the intake air temperature, further a better NOx reduction effect than the ordinary EGR.

16 Valve OHC Turbo Engine with Inter-Cooler

When the inter-cooler cools the intake air, which is compressed by a turbocharger and has reached a high temperature, the density of the increases and the combustion efficiency increases. Therefore, the new OHC main engine boasts excellent permitting high output and improvement of fuel efficiency simultaneously.

Engine and Hydraulics

The integration of the new engine system “SPACE 5” and new hydraulic system “SIH:S” has created 18% fuel efficiency improvement in comparison with our conventional model.

Low Operation Noise

The ambient noise level is reduced by 3 dB, while the noise level inside the cab is reduced by approx. 4 dB. Reduction in the ambient noise by 3 dB achieves an effect equivalent to reduction in the sound sources by half.

Common Rail Type High-Pressure Fuel Injection System

The system is equipped with a common rail type high-compression fuel injection system, which permits high-precision injection from multiple nozzles under ultra high-pressure of more than 1600 atm. Precise control of injection time and injection quantity at the rate of 1/1000 second optimizes combustion, improves combustion efficiency, and reduces PM (particulate matter) substantially.

Hydraulic Oil Flow Control

In the case of sudden lever movement and high load activation, the newly developed hydraulic control system reduces the main pump oil flow intentionally and keeps the engine speed at a constant level. This enables a reduction in fuel consumption. In addition, this also reduces the level of exhaust smoke due to excessive fuel injection.

Reduction of Hydraulic Oil Flow at Swing

The hydraulic oil quantity required at the time of sudden swing motion is limited. The new hydraulic system can start the oil flow volume at the minimum level and then allow it to increase on demand. This optimum oil flow control significantly improves the fuel efficiency.

Reduction in Pump Stand-by Pressure

Reducing pump oil flow pressure during stand-by minimizes the load on the engine. This also improves fuel consumption.

Increased Pump Efficiency

The new modified hydraulic pump structure lowers the oil leak volume in the pump which means improved pump efficiency and improved engine fuel efficiency.

High-Performance Return Filter

The hydraulic oil change interval is 5,000 hours, and the return filter change interval is 2,000 hours. One high performance return filter keeps the same level of filtering effect as a nephron. The High-Performance Return Filter is made more precisely to condensate the Nephron filter function.

Engine Oil Drain Coupler

The engine oil pan is provided with a drain coupler. This makes easier to do drain work and preventing oil from spattering with an attached drain hose.

Multifunctioning Capability for Upper and Travel Operation

With the new hydraulic circuit, travel motion slowdown and lift up are experienced even during the combined operation of attachment and swing motion when traveling.

Swing Frame

Reinforced plate on “A” frame is extended and the swing frame base is made in one-piece steel plate.

Ground Level Access to Engine Area Improves Preventative Maintenance

Parts cleaning and maintenance are possible from the ground without climbing onto the upper structure of the excavator body.

Easy Access to the Upper Structure

A large step and handrail, as well as a non-slip plate, minimize the effort when climbing on and off the upper structure.

Safe and Easy Entry into and Exit from the Cab

A large handrail for easy opening/closing of the door and a non-slip plate are installed to permit the operator to get in and out of the cab easily.

Quick and Smooth Control Response

A total review of the hydraulic circuit and miscellaneous hydraulic settings guarantee speedy and precise operation through a smooth control lever.

Automatic Power Boost

The digging power increases automatically in quick response to the working conditions without switching operations during heavy-duty digging work. It is SUMITOMO’s original design and continues for 8 seconds.

Operator Comfort

SUMITOMO's Redesigned Cabin and Seat for Optimum Operator Comfort. The seat reclining system allows the operator to tip the seat front and to rest on site without removing the headset.

Fluid Filled Cab Mounts

Four fluid cab mounts reduce vibration and impact transmitted to the cabin, improving the operator's sitting quality and reducing operator fatigue.

Automatic Air Conditioner with Round Outlets for Increased Comfort

The air outlets of the air conditioner are provided with round grills with wide adjusting angles. The efficiency of the air conditioner has been increased by pressurizing the cab to make it airtight, providing a comfortable space.

Simple to Read LCD Monitor and Switch Panel

In addition to the monitor that is easy to read during daytime as well as nighttime by changing the backlight to white, a simple and convenient universally designed switch panel is provided.

Convenient One-touch Muting of AM/FM Radio

An AM/FM radio is provided as standard equipment. The mute switch on the left lever permits one-touch muting of the radio.
