Hydradig, JCB’s wheeled excavator that looks something like a un-crashable RC car with a boom and bucket, has finally made its way stateside with an official North American launch.
We first saw the Hydradig 110W, which JCB calls a wheeled tool carrier, at its official launch during the bauma show in Munich last year. And though the unique design of this machine hasn’t changed, JCB has dropped in a new Tier 4 Final EcoMAX diesel engine under the hood. The machine made its North American debut at ConExpo 2017.
The new JCB EcoMAX engine delivers 108 horsepower and meets Tier 4 Final standards through the use of selective catalytic reduction (SCR) and diesel exhaust fluid (DEF) instead of a diesel particulate filter (DPF).
Kawasaki-KCM added two machines to its lineup of compact wheel loaders, including its smallest loader, the 30ZV-2, which joined the 40ZV-2 on display at ConExpo 2017.
The 30ZV-2 runs on a 30-horsepower Kubota three-cylinder diesel engine and Hitachi hydrostatic drive system that gives it a top speed of 9.3 mph. The 40ZV-2 rises to a 45-horsepower, four-cylinder engine, with 10.5 mph maximum speed.
Fuel consumption for the 40ZV-2 is about one gallon per hour, and drops below one gallon per hour for the 30ZV-2.
Both have standard limited slip differentials and a third spool valve for attachments. The 30ZV-2 has a .52-cubic-yard quick coupler bucket and SSL coupler, and the 40ZV-2 expands to .65 cubic yards. The 30ZV-2 has a dump clearance of 6 feet 7.75 inches and a reach of 2 feet 11 inches. The 40ZV-2 extends bucket clearance to 7 feet 7.75 inches and reach to 3 feet.
Komatsu has introduced improved models of its D51 dozers with updates including a new engine, transmission and cab improvements.
The new D51EX-24 and D51PX-24 are both powered by a 131-horsepower, 4.5-liter Komatsu SAA4D107E-7 engine. The engine improves fuel efficiency by 13 percent over previous D51 models and meets Tier 4 Final standards through the use of a diesel oxidation catalyst (DOC) and selective catalytic reduction (SCR). The dozers feature 100 percent passive regeneration without a diesel particulate filter (DPF).
The engine also features an Economy mode and auto-idle shutdown.
Also under the hood are a new water-cooled variable geometry turbocharger and a new transmission. Operators can choose between two transmission modes: A quick shift, three-speed mode and a variable 20-speed mode.
Compared to the 27D, John Deere‘s new 30G compact excavator has 22 percent more bucket force, 11 percent more arm force and a 16 percent increase in auxiliary hydraulic flow. In addition, the dig depth on the 30G is 8 inches more than the predecessor machine. The machine is the latest in the company’s G-Series lineup.
The 30G uses 27D and 26G buckets and attachments and many components common to the 35G. It is equipped with G-Series features such as mechanical pattern changers, quick couplers and proportional auxiliary hydraulics plumbed to the end of the boom. A manual wedge-style quick coupler helps you quickly change attachments.
The redesigned available enclosed cab has heating and air conditioning and a new suspension seat with wrist wrests. The foldable travel pedals are positioned to provide more foot room and low-effort pilot controls.
Doosan unveils DL420-5 CVT: Loader switches between hydrostatic, automatic transmissions based on engine speed
Doosan has introduced a significant upgrade to its DL420-5 wheel loader, equipping the machine with a transmission capable of adapting to demand.
The new DL420-5 CVT is the first Doosan machine to feature a Continuously Variable Transmission, which can switch between a hydrostatic transmission and an automatic transmission based on the speed of the engine. The company showcased the machine at ConExpo 2017 earlier this month.
At lower engine speeds, the machine utilizes the hydrostatic part of the CVT. A hydrostatic transmission not only provides better fuel efficiency at lower rpms, Doosan says, but also boosts machine performance and position control (especially when climbing or working on an incline), and reduces heat development in the digging range. Once engine rpm rises, the transmission switches to automatic. And unlike torque converter transmissions, Doosan says the CVT automatic transmission is a one-to-one ratio with the engine.
Stage V is a European diesel exhaust emissions regulation that takes effect 2019-2020. And while the United States EPA is not planning to follow suit with any emissions beyond Tier 4 Final, the changes required by Stage V are small enough that most engine OEMs will sell the same “Stage V ready” engines here and in Europe.
Kubota used ConExpo 2017 to unveil its first Stage V ready engine above 100 horsepower, the four cylinder, five-liter V5009, which is rated at 211 horsepower. In that size class, the company says the engine will be well matched to larger equipment such as production excavators and wheel loaders. Previous engines from Kubota were geared towards compact equipment.
The company started with a clean sheet of paper for the design of the V5009. The block, in particular, has been designed with a small footprint for installation flexibility, but also with large channels for coolant circulation, which will help dissipate heat more rapidly. The company says the engine will be high power but fuel efficient. For aftertreatment the engine comes with a diesel particulate filter (DPF) and selective catalytic reduction (SCR). A variety of power take off options will be available to power accessories.
Your machines are equipped with telematics but what do you do with all the data?
Volvo Construction Equipment introduced its answer at the ConExpo show in Las Vegas earlier this month. ActiveCare Direct is the company’s new machine monitoring and monthly fleet analysis service and it’s available for various Volvo models.
Data analysts staff the company’s new Uptime Center in Shippensburg, Pennsylvania, 24 hours a day, 365 days a year. They monitor the CareTrack telematics system on its machines, tracking their health and performance and looking for ways to raise productivity and cut costs, the company says.
Topcon unveils ZPS concrete paver automation, bigger machine control monitors alongside slew of upgrades and updates
Topcon unveiled a slew of new products, product improvements and upgrades at the ConExpo show earlier this month. The most significant of these is the new ZPS concrete paving system. The system is a robotic total station that operates using less hardware than a traditional local positioning system or LPS.
For tracking and guidance, the ZPS system’s Z-Robot uses what Topcon calls is Z-beam laser technology. The Z-beam provides optically based vertical control in addition to maintaining horizontal accuracy across the paver. This cuts setup time in half, says Murray Lodge, senior vice president and general manager of the construction business unit. The Z-robot eliminates the need for multiple robotic total stations to control the paver and another set of instruments for downrange transitions.
On the paving machine, the Topcon Z-stack modular system integrates GPS, optical targeting and Z-beam reception into one unit or “stack.” The system does not require a separate base station and requires only one cable for power and connectivity. It also offers a wider working area, up to 150 feet more than traditional methods, says Lodge.
