The plus by

Strong, comfortable, fuel saver and steady. These features of the midi-excavator 85V4 accompany concrete performances as to breakout and lifting force. Ten reasons for choosing it

3 Completely new machine, but with no superfluous electronics. Compared to the previous model 80VX its performances and efficiency are improved. It ensures the best value for money

The hydraulic system is traditional with first-rate components. The working cycles are 10% quicker. The tractive force has increased by 10%

2 The upper-structure base, the blade driven by a double cylinder and the strong undercarriage lower its centre of gravity. Its stability is 8% higher than the previous model 80VX

Engine Stage IIIB of the latest generation with common rail injection and Eco and auto idle operating mode. At the same power consumption decreases up to 15%

5 Upper-structure/arm joint typical of a higher category machine with a single 520 mm pin and solid cast swing unit

6 In addition to the standard 1780 mm boom a 300 mm longer version is available. All greasing points are accessible but protected

9 Clear careful construction, well arranged and recognizable hydraulic pipes (with codes and colours), well guarded electric system, Ecu control unit inside the cabin

First auxiliary line which comes as standard with proportional trimmer control on joystick. A second and a third factory line are also available

8 Cabin for the European market manufactured in Italy. High visibility (door completely made of glass) and standard air conditioning. Easy windscreen opening

Attention has been paid since the design phase to reduce the environmental impact the model 85V4 will have during its life cycle. This machine has been manufactured to last

The strong undercarriage and the blade driven by a double cylinder contribute to lower the centre of gravity. The stability of model 85V4 has increased by 8% if compared to the previous model 80VX

Additional standard 340 Kg ballast

EQUIPMENT FOR THE ITALIAN MARKET The model 85V4 has a strong base structure, upperstructure and undercarriage. The equipment conceived for the Italian market focuses on performances and includes the additional ballast as a standard feature. This element has a variable overhang, that is thinner in the final part (see the picture above).

Much torque at low speed and 42.7 kW at 2,000 rpm. But it also pays attention to consumption

ECO MODE When it is enabled it activates a specific configuration with dedicated torque and power curves. It consumes up to 15% less.

COMMON RAIL GENERATION

The electronic control unit ECU Bosch is assembled inside the cabin on elastic supports and far from heat and humidity sources. In this position it is also protected against accidental impacts during maintenance.

Injection is direct Common rail and it is managed electronically.

SELF-PROTECTED The ECU control unit detects any anomaly and if necessary it reduces power to protect the engine. Suction valve

seconds, the Auto Idle reduces the engine speed to idle. As the controls are touched lightly, the speed increases again. 6 Costruzioni

EXTERNAL EGR WITH ELECTRONIC CONTROL The exhaust gas recirculation is external and cooled on the engine Yanmar 4TNV98C. Thanks to the actuator electronic control through ECU, the recirculation is not continuous but it only occurs when it is necessary. NEW COMMON RAIL The engine Yanmar 4TNV98C (here in the VIK version) has a new high pressure Common rail injection system: this means more fuel efficiency and less consumption © Costruzioni

Regeneration request Regeneration in progress

An ultratested technology The Yanmar emission reduction system regenerates the Dpf passively and, automatically, actively according to the clogging level detected. Only when necessary, it has to be manually enabled by the operator

AUTOMATIC ACTIVE REGENERATION The automatic regeneration occurs about every 100 hours (the time varies according to the level of particulate detected in the Dpf by the ECU control unit). In this case a minimum fuel injection before the Doc is enough to increase the Dpf temperature so that it regenerates. The machine can go on working as if nothing happened. However, if the machine is in a place where a high exhaust temperature is not advisable, regeneration can be stopped and postponed.

Pressure sensors (clogging)

Condensate or rain water breather pipe

If the machine is used again and again without the Dpf reaching the suitable temperature (for instance operations with frequent machine shutdown), the electronics signals that it is necessary to carry out regeneration with a specific icon (see above, in green) accompanied by a warning sound signal. In this case regeneration must be carried out when the machine stops with the lock lever lifted, engine switched on and potentiometer idling. To restart it press the regeneration button for at least 3 seconds and regeneration will begin. The average duration is of about 25/30 minutes. Costruzioni 7

Dpf

If the midi-escavator is normally used and the optimum engine operating temperature is reached, the Dpf regenerates by itself continuously without increasing the engine speed.

HIGHER EFFICIENCY KATO IMER flagship product as well has chosen a traditional hydraulic diagram, without electronic sensors. The components are first-rate and they have all been manufactured in Japan, even those of European origin such as the double variable flow pump Bosch Rexroth reaching a maximum delivery of 75.6 litres per minute.

Each pipe of the hydraulic system has an alphanumeric code and a colour. Maintenance is easy.

The auxiliary line oil flow has two settings that can be selected directly from the cabin: Fast for the maximum flow and Slow for a halved flow.

KATO IMER has joined the movement Design for Environment. The focus is on the impact a machine will have on the environment since the design phase. The manufacturer evaluates how his machines, during their whole life cycle, can reduce the impact on health and the environment

IT CAN WORK IN URBAN AREAS The engine can look the same as model 80VX3 but actually it is the C-VIK version which complies with the pollution regulation Stage IIIB - Tier4. The Common rail injection, the auto idle and Eco mode reduce consumption up to 15%. The particulate filter allows working even in environmentally conscious town centres, but it needs a professional cleaning every 3,000 working hours. The Dpf must be replaced after 9,000 hours.
