On the Hillhead present within the UK final week (25 June 2024) Hyundai unveiled its new 100-tonne HX1000A L and 80-tonne HL985A Stage V crawler excavators, alongside the brand new 35-tonne HL985A wheel loader designed to work with a bucket as much as 7m3 – the OEM’s largest ever machine of this sort.
These heavy-duty machines have been designed to function in mines and quarries, as properly in bulk earthmoving for development and infrastructure challenge purposes. They ship excessive productiveness with decreased complete value of possession (TCO).
Excavator pair
Each excavators are powered by Perkins diesel engines, delivering energy and economic system. The HX800A L makes use of the six-cylinder Perkins 2506J, offering 400kW (539hp) at 1,800rpm and a pair of,468Nm of torque at 1,400rpm. The bigger HX1000A L is powered by the Perkins 2806J, providing 460kW (629hp) at 2,000rpm and a pair of,952Nm at 1,300rpm.
An digital hydraulic energy management system minimises gasoline consumption, whereas growing digging effectivity. It utilises 9 sensors throughout the machine to calculate the required move and pump output, delivering most effectivity.
The HX800A L has two variable displacement tandem axial piston pumps, every delivering 504 lpm of move, whereas the bigger HX1000A L has three pumps producing 523 lpm every. A closed-centre major management valve ensures that there’s minimal hydraulic move within the stand-by place, lowering gasoline use. In each machines, the pumps have a cross-sensing system to cut back gasoline use and to make sure that dig-end hydraulics function independently.
The excavators have 4 working modes and 4 energy modes, working together with variable pace management and pump torque management, permitting the operator to pick out particular engine and hydraulic system outputs to go well with the duty at hand. They arrive with a increase precedence mode and a swing precedence mode, that enhance breakout energy or slewing pace to go well with the operation.
The HX800A L is appropriate for 4.25-5.24m3 buckets and the bigger 100-tonne machine will be capable to work with 5.4-6.8m3 buckets. The 2 machines are provided with a selection of quick mass excavation and longer monobooms, and with the choice of two dipper am lengths. To ease meeting on website, the counterweight is mounted horizontally and a hydraulically-removable counterweight is out there as an possibility.
Excavator operator consolation
The HX800A L and HX1000A L have new cabs, providing degree 2 FOPS safety when geared up with a FOPS guard. The cab is suspended on vibration damping mounts, to soak up extra shocks than a easy block system. The operator has a high-quality heated seat with air suspension and the 2 machines include HD Hyundai’s All-Round View Monitoring (AVM) digital camera system, offering the operator with a 360-degree view across the working space.
An 8in touchscreen monitor with rotary controller supplies quick access to regulate menus inside the display, together with energy settings, mode operation and auxiliary hydraulic settings. The system additionally connects to Bluetooth to permit management of smartphones and different gadgets. The excavators are geared up with low-effort joystick controls, offering fingertip operation and exact management over all capabilities. Proportional thumb switches might be mounted horizontally or vertically, to go well with the operator’s choice.
“These heavyweight excavators will construct on HD Hyundai’s presence on the heavier finish of the market throughout Europe, offering a extremely productive digging and loading answer for mines, quarries, bulk earthmoving contractors and heavy civil engineering websites,” says product supervisor Gert Peeters.
Largest wheel loader
The HL985A builds on the success of smaller A-Collection machines, adopting the identical strong, sturdy design, with confirmed driveline elements and an distinctive working atmosphere. The machine is powered by the most recent Cummins X12 diesel engine. This six-cylinder EU Stage V compliant motor delivers 321kW (430hp) of energy at 2,100rpm and a powerful 2,300Nm of torque, from simply 1,400rpm. That’s 10% extra energy and 20% increased torque than earlier non-Efficiency Collection engines, regardless of decrease gasoline consumption and exhaust emissions.
The loader advantages from an Eco gauge inside the cab that displays gasoline consumption in real-time. This permits the operator to see gasoline use, engine torque, common effectivity and complete gasoline consumed, enabling extra environment friendly operation of the machine in various situations. A Sensible Energy mode additional reduces gasoline use, by adjusting the engine pace whereas loading the bucket. This reduces consumption whereas balancing traction, for improved productiveness.
Driving by a five-speed transmission with lock-up clutch, the machine can obtain most journey speeds of as much as 40km/h, making it excellent for load and carry, or longer haul rehandling duties. The transmission can be geared up with Clever Clutch Reduce Off (ICCO), which minimises energy loss within the torque converter and prevents extreme energy throughout braking. The loader has a hydraulically-locking differential within the entrance axle, to make sure most traction when digging and loading.
Constructed to work with a 6.5m3 or 7m3 bucket, with or with out tooth and chopping edges, the HL985A’s Z-bar linkage parallel raise arms present a dump clearance at most peak of as much as 3,360mm. Bucket breakout drive is as much as 28,400kg and the machine has a full flip tipping load of as much as 24,950kg when geared up with the heavier counterweight. The HL985A has an working weight of round 35,350kg, relying on specification.
New wheel loader cab
The HD Hyundai A-Collection loader cab is round 10% bigger than on earlier fashions, offering the operator with a snug, quiet working atmosphere. The ROPS/FOPS cab has a completely adjustable, air suspended, heated seat, with an adjustable armrest permitting the operator to seek out the proper driving place. A 7” color touchscreen is simple to know, offering all essential data at a look.
Operators profit from a Bluetooth audio system with a hands-free perform, permitting name answering and music option to be made whereas working. As well as, the HL985A has a full color, built-in rear view digital camera, seen by the principle monitor. The machine is obtainable with HD Hyundai’s market-leading All Round Imaginative and prescient Monitor (AAVM) system, that employs a number of cameras to supply a 360° view across the working space.
“The HL985A units a brand new efficiency and productiveness normal for HD Hyundai within the heavy wheel loader sector,” says product supervisor Stefan Schwill.
“Appropriate for a variety of duties, in quarrying, recycling and rehandling purposes, the HL985A gives extra energy for much less gasoline used, delivering a complete value of possession profit for purchasers.”
