Eight mini excavators from Hyundai

HD Hyundai unveils eight mini excavators, with operating weights of 1.7 to 5.5t. The excavators join existing Hyundai mini and midi crawler machines to form a 12 model range, from the 1t HX10A micro through to the 9t segment HX85A. While all models feature compact dimensions, those with a ‘z’ suffix offer a zero-tailswing design and can be supplied with additional counterweight. The smaller models also feature variable-width undercarriages. Safety valves are standard on all boom, dipper arm and dozer blade hydraulic cylinders, and the boom, arm and bucket cylinders also come with guards. Furthermore, all machines can be supplied with optional quick-coupler piping. A float function is included in the dozer blade hydraulics, while an optional angle blade is available on HX35Az and above. The cab has Bluetooth connectivity, and the machines come with a waterproof 5” digital display which provides operating data and can be used to program auxiliary hydraulic flow or to set the anti-theft protection code. The machines use hydraulic joysticks, and proportional roller switches can be supplied in the joystick heads. All models from the HX40A are equipped with a load-sensing hydraulic system. They also feature a variable displacement pump with flow sharing capabilities. The main control valve is installed on the right of the machine. Large rear and side engine compartment doors provide access to service points, with heavier models offered with a tiltable cab. All filters and fill points can be reached from ground level, and there is a lower chassis connection interface for the dozer cylinder hoses. HX-A Series can be supplied with the Hi Mate remote management system which uses GPS technology to provide telematic operating data. Hi Mate can also be used to set geofence alerts that will notify customers if machines are moved from a predetermined zone without authorisation.

They have a pressed steel bodywork, cast counterweight, ROPS/TOPS cab, suspension seat, 4” digital multi-function screen, and more. The screen displays engine rpm, coolant temperature, fuel gauge and information customised by the operator. The screen contents can be set to, for example, display engine/service hours, auxiliary flow status and lift overload status. The operator can adjust auxiliary flows, windscreen wiper frequency and auto-idle activation times. Service engineers can also access diagnostic information. The machines are supplied with a 18.4kW EU Stage V/ Tier 4 Final compliant Kohler diesel engine. A new main valve block delivers flow sharing, while auto kick-down track motors adapt to terrain. The double-acting auxiliary circuit delivers 48l/min to power attachments. A single to double acting changeover valve is controlled by a switch. A double-acting low-flow circuit is offered as an option. The operator can select high and low flow modes using 0-100% of the hydraulic flow, and auxiliary relief pressure can be adjusted on machines with both high and low-flow circuits. The 25Z-1 has a maximum digging depth of 2,824mm, while the 26C-1 offers up to 3,037mm of excavating capability. Both models feature the 2Go hydraulic isolation system and immobiliser. JCB also offers a factory-fit hydraulic quick hitch option. Other options include a new mechanical hitch, a factory-fit hydraulic thumb and lightweight buckets.

Komatsu presents three new electric mini excavators at Intermat 2024

Komatsu announces the launch of three new electric mini excavators at Intermat 2024. The PC20E, PC26E, and PC33E, complete with new cab specification, are especially focused on the European market, and offer customers a solution for a variety of excavation tasks. “Komatsu is committed to developing innovative and sustainable technologies that meet the evolving needs of our customers,” said Emanuele Viel, Group Manager for the Utility line at Komatsu Europe. “The new electric mini excavators are a confirmation of this ongoing commitment, offering zero emissions operation without compromising on performance. Komatsu set a challenging target of becoming carbon neutral by 2050, which means virtually eliminating CO₂ emissions not only from our own sites and from the use of our products, but also from customers’ sites. Komatsu aims to meet the needs of our customers by introducing a diverse range of electrified construction equipment.”

The new machines offer a range of features, including, in Komatsu’s own words, Zero Emissions Operation since the electric motors produce no exhaust fumes, making them suited for use in indoor environments or emissions-sensitive areas; noise reduction; high torque and power; high-capacity batteries that provide sufficient runtime for a working day on a single charge; electric motors which require less maintenance than traditional diesel engines; operating weight designed to meet European requirements for trailer transportability; and onboard charger available for PC20E and PC26E.

e12, the first Mecalac zero emission excavator

Mecalac launches their new 10-12t fully electric e12 excavator. The power source, which is separate from the turret, enables a capacity of 150kW.h to be installed, offering an autonomy of 8h. Since the e12 is electric, it does not have CO₂ emissions or other polluting particles, contributing to the decarbonisation of worksites. Moreover, electric vehicles can feature less vibration and noise pollution. Being an electric version of Mecalac’s diesel-driven 12MTX, the e12 is said to combine Mecalac’s technology with their know-how in construction equipment and fit within their goal of moving towards urban construction sites that are more compact, efficient and environmentally friendly. The construction borrows from the 12MTX, but the location for the engine now houses lithium NMC battery technology (Nickel-Manganese-Cobalt), suited for onboard solutions. This technology combines weight power/quality ratios with an optimized service life and safety, according to Mecalac. This machine can be recharged at the same charging points as cars, and require 8h for a full charge (using for example Type 2 sockets or 5-pin 3P+T+N sockets).

 New fully electric loader from Avant 

While technically not an excavator, a new novelty from Avant Tecno is still worth having a closer look at. Avant launches two next generation fully electric loaders, the Avant e513 and Avant e527, which will renew the Avant e series and replace their predecessors. The new loaders are equipped with Avant OptiTemp battery packs (13 kWh and 27 kWh) manufactured by Avant Tecno’s subsidiary Avant Power. The Avant e513 and e527 are almost identical; the difference lies in the capacity of the batteries. The Avant e527 (27 kWh) with a larger battery is ideal for professional use, for example in construction and demolition, while the e513 (13 kWh) is suited for short-term continuous use for leisure, cattle farms and DIY, for example. The Avant e527 can be used in confined spaces and on construction sites that have strict limits on noise and emissions. It can be used for a whole working day when fully charged in the morning, has a maximum operating time of 6h for medium-duty work, and can be fully charged with a fast charger in under 1.5h, while the thermal management system of the patented lithium-ion batteries guarantees the same capacity in hot and cold temperatures, according to Avant. The OptiTemp batteries feature multi-level protection with the purpose of increasing safety. The lift capacity is 900kg, maximum lifting height 2790mm and drive speed 10km/h.

 Ausa expands its range of electric dumpers 

Ausa also releases models that are not technically excavators, but still might be of interest for anyone looking to find ways to facilitate work on the jobsite. The new D101AEA and D101AEA Compact feature a 1,000kg payload, and a front and high-tip skip. With these models, Ausa now has a total of three electric dumpers in its product line-up. The models share the same platform, but their optimal operating conditions provide different options: while the D101AEA is a narrow dumper (108cm), the D101AEA is equipped with small 12in wheel rims that reduce the overall width of the machine to 100cm. This allows this electric model to fit through building and residential doors. Both models have a battery pack with a maximum power of 19.6kW and a torque of 130Nm. The lithium-ion batteries have a capacity of 9.3kWh and can be charged from 20 to 80% in just two hours by plugging them directly into a 230 V mains socket, or in one hour with an external fast charger, according to Ausa. Ausa’s goal is designing an electric vehicle range where each vehicle can operate for at least one intense shift. Their models are powered by lithium-ion batteries.
