Hyundai digs into the future of construction with hydrogen-powered excavator at bauma

At this year's bauma trade show in Munich, Hyundai Construction Equipment will have 18 machines on display, including 10 that are completely new or updated. At the Hyundai CE booth is a full demosntration area and an Innovation Park of future technology. 

Hydrogen excavator digs in at bauma exhibition

Hyundai will have its HW155H hydrogen fuel cell-powered wheeled excavator concept working on the demonstration area during this year's bauma trade show in Munich. The pre-production machine will demonstrate how hydrogen can contribute to future carbon-free operations on construction sites.

The HW155H is a 15-tonne wheeled excavator that combines on and off-road capabilities, making it an ideal choice for hydrogen power. The machine uses the fuel cell to power anelectric motor that then drives the hydraulic system. The hydrogen storage on board can allow eight hours of operation, with refuelling taking between 10-20 minutes.

The use of hydrogen fuel in the future 

A hydrogen fuel cell uses a chemical reaction between hydrogen carried on board and oxygen in the atmosphere to generate electricity with the only emission being water vapour. The fuel cell delivers power on demand to drive the machine either through electric motors or electrically-driven hydraulic pumps.

The safety of hydrogen fuel will make its use an acceptable solution for infrastructure, civil engineering, and building projects worldwide. Hyundai's high-density, solid-state storage system will double the capacity of a conventional hydrogen tank, using a considerably lower filling pressure. This system will optimize space within the machine, reduce fill times, and improve safety on site.

Hyundai CE moves into a new market with the HD130A dozer 

Hyundai CE is expanding its equipment line-up with the launch of a mid-weight dozer. The HD130A delivers enhanced tractive effort, clean grading performance, and a range of smart technologies.

Viewers can expect to see the following on display at bauma this year: 

• Fully electrohydraulic controls and 2D Blade Dozing Assist Function for total control
• Narrow nose with inline pre-cleaner and maximum glazing deliver improved visibility
• 117-kW (157-hp) engine offers an enhanced level of power output
• Cab tilt allows access to major driveline components
• Touchscreen displays for all machine settings and information that doubles as a rear-view camera
• ROPS/FOPS cab rides on CabSus mounts that dampen vibrations
• GPS-satellite technology provides customers with real-time machine-operating data

Pushing power

The HD130A is powered by a Perkins 4.4-litre diesel engine. An Eco Mode can be selected for lighter grading duties, lowering the hydraulic pump power output, and reducing fuel consumption by 5 percent. Auto Idle and Auto Shutdown features minimize fuel use over the working shift.

The machine has a reversible hydraulically-driven cooling fan for the engine and hydraulic oils, with an electrically-driven fan for the charge air cooler that can also be reversed to clean out the core. The cooling system located towards the rear of the machine ensures that cooling cores are situated out of dusty areas.

A variable displacement axial piston pump provides 132 litres/min of hydraulic flow, providing the machine with a traction force of 22,000kgf. The two-speed transmission offers a travel speed of up to 9.0km/h.

There are two six-way power-tilt angle dozer options. The tilt and angle adjustment makes it easier to work more efficiently, reducing the number of passes required to achieve grade. A two-way mechanical adjustment also allows the operator to set the blade pitch from 54 to 58.

Innovation Park points the way to the future of technology

Hyundai Construction Equipment at bauma will feature an Innovation Park that will demonstrate how technology can play an increasing role in machine control and operator safety. Available to see at the Innovation Park display is an HL955A wheel loader that is operated remotely. 

Tech features on the HL955A wheel loader 

Information such as the front distance, bucket angle, and bucket height will be displayed on the control screen, allowing operators to access working data at the controls. The system also plays surrounding sounds through its speakers, making the operator aware of site conditions.

The system incorporates a tilt angle sensor on the loader to prevent tipping when the loader arms are being raised and an emergency stop button on the remote control unit. The loader will also be equipped with the latest version of HD Hyundai's Advanced Around View Monitoring system, which uses radar to detect obstacles in the loader's predicted path when reversing. 

The HL955A will be equipped with the company's new Clearview X bucket that uses AI-based video technology to provide the operator with a view through the bucket to the loading or unloading area.

Visitors to the stand will be able to experience both 2D and 3D machine guidance and control through an excavator simulator. The system is available to work with all A-Series excavators. Also on show will be a wheel loader cab of the future, with a Head-up Display (HUD) that projects operating information onto the front windscreen.

Hyundai extends range with material handler 

Hyundai Construction Equipment is introducing another new machine at bauma; the HW250A MH is a dedicated materials handler for the recycling and waste handling industries. 

High lifting abilities 

Weighing 26.1 tonnes, the machine comes with front and rear outriggers, providing enhanced stability when lifting. Equipped with a 6.5-metre mono boom, the handler has a 4.5-metre gooseneck arm for use with an orange peel grapple or a clamshell bucket. Alternatively, contractors can opt for a 4-metre straight arm if using a sorting grab. Maximum working height is 12 metres with either configuration.

Sitting on a 2.8-metre wheelbase, the materials handler has a parallel lift cab that delivers up to 2.9 metres of additional height, to allow operators to see into the working area. The support frame is constructed as a box structure for durability. There is a manual lift control in the cab and a second control at ground level in case of emergencies. 

Built with operator comfort in mind

The operator's seat and controls can be adjusted to suit all sizes of drivers, with independent height options for the seat and console. There is a high-capacity air conditioning system and the wheeled excavator cab has extensive glazing for maximum visibility. The monitor provides real-time operating data and various diagnostic functions and can be used to display the rear- and side-view camera feed.
