The new HL970 is making its way to the European market and is expected to land in the beginning of 2016. The new 23.5 tonne wheel loader, with a 3.6–4.2 m³ bucket capacity, is currently the largest of its stable mates which comprises the recently introduced 15 tonne HL955 and the 18.8 tonne HL960 completing the new wheel loader lineup for now.
The HL970 is powered by a Scania DC09 085A Stage IV engine boasting a gross 311 hp (232 kw). Hyundai has opted for a combined solution of EGR and SCR technologies, without the need for an additional DPF. The new machine is up to 10% more fuel-efficient in truck loading than its Dash 9A Series predecessor, depending on the application, and has a travel speed of up to 40.0 km/hr (24.9 mph).
New exterior design
The robust and powerful HL970 is well suited to the quarrying, mining, construction and material handling sectors. The high-strength design structure and robust system has been proven by rigorous road tests at various work sites. The durability of the hydraulic hoses and attachments has been improved significantly compared to the previous generation of Dash 9A Series.
In addition to its fuel efficiency, the HL970 benefits from an ECO Pedal, which when the operator uses the accelerator pedal, he/she is able to distinguish between economical operation and power operation – it recognizes the economical operation which in turn reduces the fuel consumption.
The HL970 is also fitted with an ECO Gauge which enables the economic operation of the machine. The gauge level changes color with the engine torque and fuel efficiency level. It’s also able to provide the status of fuel consumption - such as average rate and the total amount of fuel consumed are displayed. Hourly and daily based fuel consumption can be checked in detail which helps the operator run the machine more economically and efficiently.
The HL Series of wheel loaders has a function that turns the machine off when it enters an ‘idling’ state which also minimizes unnecessary fuel consumption and emissions. Operators can select operating mode depending on work environments which improves its efficiency even further. The five-speed transmission with Lock-up Clutch on this machine also aids fuel consumption depending on the working conditions.
Brand New Weighing System
The HL Series improves work precision with additional accuracy. The automatic/manual cumulative weighing function greatly improves operating efficiency. Icons displaying weighing errors and the two-color weight value indicator on the monitor enable accurate weighing to support efficient production management.
Hyundai engineers have also redesigned the wheel loader buckets on the HL Series and they now have a better fill factor and an additional spill guard to minimize spillage of loaded materials. The HL970 boasts up to 5% greater productivity in comparison to the Dash 9A Series. The boom and bucket are both controlled by either the joystick or fingertip system.
New Cabin Design
The cabins on the new HL machines have been designed with the operator's safety and comfort in mind. As well as more space in the cabin with up to 10% more leg room, there’s a bigger and more comfortable seat with an adjustable arm rest with integrated control levers for attachments. The Electro-Hydraulic Control allows the joystick to move along with the seat when being repositioned. For ease of access and egress the cabin door now turns in the opposite direction with the hinges located on the front-side.
The cabin is also fully sound-proofed which ensures maximum silence (72 dB) when working in noisy environments such as quarries or waste handling depots – the new HL machines benefit from a 2 dB reduction in cabin noise over the Dash 9A Series.
A new Air Conditioning System maximizes heating and cooling by optimizing airflow. The capacity of the inner filter was increased and the material changed for first-class filtering performance. It’s also easy to maintain located on the right hand side of the cabin.
Hyundai’s ‘infotainment’ system for the operator’s convenience
The HL970 is optimized to enable operators to access accurate equipment data quickly. This feature is of particular importance when working in tough environments to improve productivity.
The intelligent 7-in. wide touchscreen monitor is similar to a smart phone display and is larger than the previous models and provides excellent legibility. The Audio System has an integrated Bluetooth hands free feature, and a built in microphone allowing the operator to take and make calls when in the cab.
The ‘infotainment’ system also allows the operator to enjoy the Miracast system which works via the WiFi of the operator’s smart phone and enables easy use of the smart phones features on the big screen including navigation, web surfing, watching videos and listening to music.
Soft end stop
The touchscreen monitor and Electro Hydraulic Controls allow several (new) features like ‘Soft End Stop’ to be controlled through the touchscreen. The ‘Soft End Stop’ delivers - when an attachment reaches the end of a stroke - a ‘shock free’ operation by reducing the speed of the attachment near the end stroke. This function can be disabled through the monitor should the operator not want to use this function.
Ease of maintenance
The HL Series has a large-volume air cleaner, an automatic dust ejector and a three-stage air pre-cleaner, as an option, to improve the replacement cycle and durability of supplies. The machine also has a fully sealed engine room, designed to prevent the possibility of fire caused by the inflow of ‘foreign materials.’ A flick of a switch is all that it takes to access the engine compartment of the new HL Series of wheel loaders. The electronically operated fully retractable engine hood allows easy cleaning and maintenance. The initial replacement cycle of oil and filter is extended to 250 hours to further reduce the maintenance costs.
Larger dumping height
The new wheel loader is also available in XT version (larger dumping height).
