Though offering similar operating weights, the HX130A LCR, HX140A L and HX145A LCR deliver very different performance operating envelopes to suit a range of customer requirements. The reduced swing HX130A LCR, which will appeal to rental customers, is powered by a 55kW version of the Cummins F3.8 engine. The engine meets the EU Stage V emissions standard without the need for an exhaust fluid such as AdBlue. The HX130A L also benefits from Hyundai’s ECD engine connected diagnostics, providing remote diagnostics and ensuring that technicians arrive at the machine with the required parts and tools. The conventional counterweight HX140A L uses a more powerful 100kW version of the Cummins engine to deliver maximum digging forces and higher productivity.

The third model to benefit from the Stage V update is the HX145A LCR. Like the HX130A LCR, this reduced tailswing model is particularly suitable for applications where space to manoeuvre is at a premium, such as utilities, road working and housebuilding. Boasting the same 100kW output as the HX140A L, the engine is said to deliver an 8% power boost over its predecessor, while delivering a 4% fuel economy gain and a 60% reduction in PM emissions. The HX145A LCR delivers up to a 6% fuel improvement in levelling work and a 3% drop in consumption during truck loading when compared to the HX Series model working in P mode. As with the conventional tailswing models, the compact radius excavator offers service intervals of up to 1,000h when operating with CK-4 E/G oils. The machine also features Hyundai’s ‘HCE-DT Air’, permitting wireless connection to the excavator from a smartphone or laptop computer on site. This promotes rapid diagnosis and reduces costly downtime.

The ‘HX A’ Series machines have an upgraded IPC system, tuning pump flow rate and power to meet operator demand. The design of the main control valve and the hydraulic pipe layout has also been optimised to minimise energy loss throughout the system. A new ‘Lifting Mode’ improves fine control and lift capability, reducing engine rpm, activating power boost and offering improved pump flow control. The machines are also offered with an optional ‘Fine Swing Control’, smoothing the movement of the boom at the start and stop of the swing movement.

The HX A Series excavators benefit from a host of digital connectivity technologies. This includes the proven standard ‘Hi Mate’ remote management system that delivers high levels of service connectivity and remote diagnostic ability. The ‘Mobile Fleet App’ has been updated to allow fleet owners easy access to machine operating data, including economical usage, utilisation and fault code recognition.

Optional ‘Engine Connect Diagnostics’ (ECD) allows technicians and dealers to support customers with diagnostic reports and engine performance data. HCE-DT Air also allows the customer to connect wirelessly through a smartphone or laptop on site.
