At the Hillhead exhibition in Buxton, Derbyshire Hyundai launched the brand new HX430 L (44,120 kg/97270 1b) crawler excavator, with a bucket capacity of 1.90 m³/2.49 yd³ – with an overall width of 3,340 mm with 600 mm shoes.
The new HX430 L machine had just rolled off the production line – in fact it was touch and go whether the excavator would make it to the UK in time for the show!
The HX430 L was exhibited fitted with a Strickland S-lock Quick Coupler and a Daemo B360 Breaker.
Strickland’s S-lock quick coupler is manufactured using 400 brinell wear resistant steel, which in turn makes it very strong.
According to Strickland, the S-lock has the fewest moving parts in any double locking quick coupler, making it simple.
The independent secondary locking system is a design safety feature and both front and rear attachment pins are secured by positive locking forces. The Variable pin pick-up range is compatible with majority of attachments.
The Daemo B360 Breaker, designed for 32-44 tonne excavators, is part of the Daemo Alicon Series. Daemo say that this breaker has been created with state-of-the-art technology, which has made it possible to lower weight and increase breaking power at the same time.
The premium breaker has considerably improved durability through strengthening its main components.
Fuel Efficiency – systems to reduce consumption and engine emissions
Powering the HX430 L is a Cummins QSL9 4-cycle turbocharged air cooled diesel engine which complies with the latest emission standards Stage IV for the reduction of particles and Nox in exhaust gasses, and is rated at 316 HP (236 kW).
There is easy access to DEF/AdBlue Supply System. The DEF/AdBlue tank is installed inside the tool box and its inlet is remotely located for easy access and convenient supply.
Warning of overfill is given by a red lamp signal. The DEF/AdBlue supply module is attached on the side of the fuel tank for easy maintenance and filter replacement.
The new HX range is fitted with an ECO Gauge which enables the economical operation of the machines.
The gauge level and colour displays engine torque and fuel efficiency level on the touchscreen monitor. In addition the gauge indicates the status of fuel consumption such as average rate and the total amount of fuel consumed.
The HX range can offer a reduction in fuel consumption of up to 8 per cent – depending on the type of operation – in comparison to Hyundai’s 9A-series of machines.
Hourly and daily based fuel consumption can be checked in detail which helps the operator run the machine more economically and efficiently.
The excavators (HX series) have a function that turns the machine off when it enters an ‘idling’ state which also minimises unnecessary fuel consumption and emissions.
Operators can select operating mode and ‘idling’ time depending on work environments which improves its efficiency even further.
The IPC (Intelligent Power Control) controls power depending on work environments. Its mode can be selected and released on the monitor – on the excavation mode – pump flow can be more cleverly controlled, reducing fuel consumption.
The new Electronic Fan Clutch offers the highest in control efficiency and the best in fuel efficiency. There is also an Eco Breaker Mode where two hydraulic pump summation is available for breaker operation.
New, Exclusive Safety Features
New safety features include Hyundai’s exclusive AAVM (Advanced Around View Monitoring) System for 360° – surround virtual operating view – which displays on the 8 inch cluster-monitor.
The system consists of an Around View Monitoring (AVM) system that give a 360°-surround virtual operating view and an Intelligent Moving Object Detection (IMOD) system that senses and warns the operator when objects come within working distance of the machine.
An interactive demonstration of the AAVM System is on display at the Hyundai stand at Hillhead.
Enhanced Instrument Panel for Easier Monitoring Simplifying the Control Settings
One important innovation on the new HX range is the new and larger 8 inch touchscreen monitor – the cluster monitor can display information that mirrors what you would see on your smart phone and is 30 per cent larger than previous models.
It’s also easy to read and the main view of the screen can be adjusted according to the preferences of the driver. It can be controlled via touch control and/or new haptic controller.
Connecting to a mobile phone is easier than ever with the bluetooth connection to the machine’s radio.
Flow and pressure setting for attachments – new options available
The new machines can offer up to 10 breaker and 10 crusher settings, where both flow and pressure requirements for the attachments can be saved on the machine.
With the floating boom option, the boom can float freely by connecting to the cylinder head and/or the rod directly to the tank.
Other new options include – Fine Swing Control which can be installed in order to ensure a softer stop of the swing with minimal shock load.
A Swing Lock is an operator-controlled locking mechanism which cuts off swing pilot signal. A Straight Travel Pedal is also an option – the straight travel pedal reduces operator fatigue while traveling greater distances.
Instead of holding down both right and left pedals the operator can easily travel by just holding down one pedal.
Cycle time improvement
The new HX range provides higher productivity on-site by faster operation and can load trucks up to 19 per cent faster and levels up to 8 per cent faster than the 9A-series.
In order to achieve efficient grading, the HX series can apply an optional boom floating control using arm-in and arm-out operation only, allowing stable operation even in high-load work.
New exterior design increases durability and safety
HX range have newly designed cabins – a new larger front screen has been incorporated and the driver’s door is now easier to open from the inside with an additional handrail.
The interior of the HX cab offers 13 per cent more space for the operator (compared to 9A-series). A newly developed air conditioning system provides better air circulation in the cab.
The cab suspension mount reduces the noise inside the cabin.
Hi-mate (Remote Management System)
The HX machines are also fitted with Hi-Mate, which is a remote management system, developed by HHI. Through its satellite powered technology, customers can enjoy an unmatched level of service and product support.
With one press of the button, users are able to remotely evaluate machine performance, access diagnostic information and verify machine locations.
It’s even possible to program a virtual ‘geo-fence’ to prevent the machine from leaving a specific area.
Reliability and Serviceability
Enhanced reliability features on the HX series include reinforced longer-life pins and bushes coupled with wear-resistant polymer shims and newly designed cab shock mounts with dual shock absorption for reduced vibration and noise, which also improves operator comfort.
Serviceability enhancements include ground-level access to the fuel filter and convenient exterior access to the cab air filter.
Additional guard rails provide greater safety while performing maintenance and inspections on the upper structure deck.
Reinforced Durability of Upper and Lower Structure and Attachments
The upper and lower structure and attachments of the HX series have a far higher durability than demanded on the site, proved through numerous tests, including road tests and virtual simulation.
The wear resistance of the bucket has been improved by use of new material. The durability of the arm and boom has been reinforced by 1.5 times (compared to 9A-series).
Almost Doubled Durability of the machine front for HX430 L
The new boom and arm durability for HX430 L has radically been enhanced. Principal dimensions have been increased at the most critical section while their total weights were kept the same by means of structural optimization.
A completely new welding technique, which was developed to remove the back plate, also contributed a lot to the improvements of the HX430 L.
The new attachments have been proved to last at least 1.8 times longer than those for 9-series.
