Wirelessly monitor concrete curing with Maturix Smart Concrete Sensors

A thermocouple wire is plugged into the reusable Maturix sensor to transmit data to the cloud.

Maturix Smart Concrete Sensors, introduced at World of Concrete 2020 by Kryton International, wirelessly monitor the concrete hardening process, eliminating the need for manual data collection.

The sensors transmit concrete temperatures at chosen depths in real-time to internet-connected devices. The system then automatically estimates the concrete’s maturity and strength, the company says.

The sensors use the Sigfox 0G internet-of-things network to transmit data to the cloud for access anywhere in the world. The concrete sensors’ batteries can last for 10 years, the company says. The sensors receive temperature data from sacrificial thermocouple wires that are attached to rebar before concrete is poured. After the concrete is poured, the thermocouple wire is plugged into the reusable sensor to transmit data automatically every 10 minutes.

The sensors have been used on construction projects in Europe. Maturix was developed by Denmark-based Sensohive Technologies, which started in 2015. Canadian firm Kryton acquired 30 percent of Sensohive and is introducing the product to North America.

Manitowoc Cranes to intro 5 new Grove models at ConExpo 2020

Grove GRT8120

Manitowoc Cranes will unveil five new Grove models at its during ConExpo, including the Grove GRT8120. The 120-ton rough-terrain crane has a 197-foot  boom length and a new carrier design. The company will be located at booth F6144 in the Festival Grounds.

Manitowoc says the GRT8120 features “the longest boom and strongest load charts in its class, along with a new compact carrier design with flat decking for improved maneuverability, serviceability and job site access.” Industries targeted for the machine include the petrochemical, construction and wind power industries, among others.

(You can see more of what OEMs have in store for ConExpo 2020 in our show preview page by clicking here.)

“Many of our customers wanted to fill a void in the 120-ton class, and also increase their crane utilization with easier transportability, greater reach and capacity, and improved access for serviceability,” says John Bair, product manager for rough-terrain cranes at Manitowoc. “We were able to accomplish this through an all-new carrier design along with several other new features debuting on this crane. We’re happy to say that the 197-ft boom length and strong load charts put this crane at the top of its class.”

Based largely off the GRT8100, the GRT8120 has a 265-foot max height when equipped with the 57.6-foot bi-fold swingaway extension that comes in either manual or hydraulically offsettable configurations. The crane features a MAXbase asymmetrical outrigger system that aids maneuverability in congested jobsites requiring maximum reach.

A new, wider, full-vision cab with 20-degree tilt assists operator comfort and visibility. A Boom Configurator mode simplifies telescoping of the boom and provides on-board lift planning. It can be easily transported to job sites and needs minimal job site preparation

With a 15-mph travel speed with full counterweight,  the GRT8120 has smart sensing outrigger cylinders in lieu of string pots.“We’ve also added a wireless, handheld rigging remote for quick and easy set up on site,” Bair says. The CCS Crane Control System improves efficiency and reduces training time, according to the company.

The other new Grove cranes at ConExpo will include the previously released GRT9165 rough-terrain crane, GHC140 telescoping crawler crane, TMS500-2 truck crane and a yet-to-be-announced model.

Nikola unveils electric Badger pickup: Huge range and built for construction work

The latest electrified pickup to join the fray is from Nikola Motor Company, the builder of a hydrogen-electric Class 8 tractor. The company recently announced the 906-hp Badger pickup which features an estimated range of up to 600 miles and a hydrogen-electric powertrain.

The company says the pickup delivers 980 ft.-lbs. of torque, 906 peak horsepower and 455 continuous horsepower with a towing capacity of more than 8,000 pounds. The truck will be built in conjunction with an unnamed OEM using their certified parts and manufacturing facilities.

The truck will be available with a fuel-cell electric (FCEV)/battery-electric (BEV) hybrid or battery-electric only powertrain. The company says it can operate in FCEV/battery-blend or BEV mode only at the touch of a button. The Badger can drive 300 miles in BEV mode for those that do not have access to hydrogen.

Nikola says the truck is designed to handle what a construction company could throw at it and features a 15-kilowatt power outlet for tools, lights and compressors.

“Nikola has billions worth of technology in our semi-truck program, so why not build it into a pickup truck?” said Nikola CEO Trevor Milton. “I have been working on this pickup program for years and believe the market is now ready for something that can handle a full day’s worth of work without running out of energy. This electric truck can be used for work, weekend getaways, towing, off-roading or to hit the ski slopes without performance loss. No other electric pickup can operate in these temperatures and conditions.”

It looks like the Badger will be either a Class 2 or 3 pickup based on the following statement: “With a fully loaded trailer and combined vehicle weight of 18,000 lbs., the Badger will be able to launch from a standstill on a 30 percent grade without motor stall,” Nikola’s press release states.

Time for a little math. Take the combined vehicle weight of 18,000 pounds (which under normal circumstances accounts for the weight of the trailer, vehicle and all contents and passengers), subtract the stated 8,000 lb. max towing and you’ve got a Class 2 10,000-lb. GCWR truck. Add a pound of bacon or whatever and it becomes Class 3.

The Badger will be outfitted with a 15-kilowatt power outlet for tools, lights and compressors, which is enough power to assist a construction site for approximately 12 hours without a generator.

The Badger was designed to handle 0-100 mph launches with minimal loss of performance and to operate on grades up to 40 percent through advanced software blending of batteries and fuel-cell.

“The Nikola Badger is a game changer. The program will help drive down the cost of the fuel-cell components on our semi-truck while accelerating the hydrogen station rollout. Giving customers the option to order a fuel-cell or battery electric version will ensure we drive the cost down for everyone across our lineup,” said Mark Russell, president of Nikola Corporation.

Nikola has partnered with Diesel Brothers’ Dave “Heavy D” Sparks who will design, build and test the Badger for millions to see on the popular reality TV show.

New truck plans can make strange bedfellows. Sparks has built a successful TV show and businesses based on truck builds with high-performance diesel powertrains. Milton has not hidden his disdain for oil burners. Consider his comments last April at the Advanced Clean Transportation Expo in Long Beach, Calif:

“Hashtag diesel is dead. Emissions game over. We’re tired of it,” Milton told a large audience during the Expo’s general session at the Long Beach Convention Center. “We need to fix a lot of the problems and change things. Other people are not going to do it unless they’re forced to, so If that means we have to force them, it’s about damn time.”

In a video posted Monday by Milton on Twitter, Sparks acknowledges the challenges that his longtime propulsion of choice is up against.

“What I’m about to tell you is the single most important announcement of my entire career. Listen, the world’s changing,” Heavy D says. “Many cities and countries have started to put a ban in place on gasoline and diesel-powered vehicles. As truck owners, our trucks are our lifestyle, our livelihood, and our passion. And I for one refuse to be caught unprepared.”

A limited number of reservations for the Badger will be available in 2020. The truck will make its first appearance at Nikola World 2020, which is expected in September.

Additional details on the Nikola Badger

  • Electric 0-60 mph in approximately 2.9 seconds
  • Truck can operate on FCEV / battery-blend or BEV mode at any given time
  • Badger can generate over 906 horsepower, 980 lb.-ft. torque and an estimated 600-mile range
  • Badger can drive 300 miles in BEV mode for those that do not have access to hydrogen
  • Badger will make its first appearance at Nikola World 2020; expected in September
  • Nikola is currently planning 700 hydrogen stations to give North America hydrogen coverage
  • Initial hydrogen station locations are finalized and will be announced this quarter
  • Limited reservations available in 2020. Sign up for updates at http://www.nikolamotor.com/badger

Wirtgen debuts machines for all new paving train at World of Concrete 2020

A graphic of Wirtgen’s new paving train

Wirtgen introduced its SP124i slipform paver, WPS 62i placer/spreader and TCM 180i self-propelled texture/curing machine at World of Concrete 2020.

The company displayed the new machines as part of a simulated inset concrete paving train at its  booth at the show.

Wirtgen also put on a live demonstration of its AutoPilot 2.0, a three-dimensional control system for automated paving.

Leading the paving train: WPS 62i spreader

The new WPS 62i placer/spreader is the first machine in Wirtgen’s paving train at the show. The two-track machine is designed for paving when reinforced steel has already been placed and concrete must be applied from the side.

The placer/spreader passes fresh concrete over pre-placed reinforced steel in front of a slipform paver. The concrete is fed from the side to the spreader, which then evenly distributes over the entire working surface, the company says.

The spreader can feed at paving widths of 12 to 24 feet, which can be adjusted by removing individual segments.  It can apply concrete up to 20 inches thick.

The placer/spreader has a modular design and quick-change couplings for easier reconfiguration and transport.

Mid-train: SP 124i slipform paver

Wirtgen says its SP 124i is the first slipform paver with a working width up to 40 feet that it has equipped with four steerable and slewing crawler units. It can also be equipped with a new hydraulic rotational drive system with a 260-degree steering angle.

The paver is designed with a narrow profile and reduced track line to allow paving close to obstacles. By pushing a button, the four crawler units can be switched to rotation mode, allowing the paver to turn on the spot and pave the next lane in the opposite direction without having to reposition the machine, the company says. The paving legs can be swung in hydraulically for transport.

Behind the paver: TCM 180i curing machine

Wirtgen’s new TCM 180i self-propelled texture/curing machine is equipped with an automatic spraying and brooming system to create the desired surface texture.

As it follows the paver, the spray system applies a coat to the surface to prevent the concrete from drying out too soon. The modular design allows widths between 13 feet 1 inch and 59 feet 1 inch.

Cutting the stringline

With the Wirtgen AutoPilot 2.0, the Field Rover measures the virtual stringline support points. Using all measured points, the software calculates the optimum course for concrete paving, the company says.

Wirtgen’s AutoPilot 2.0 eliminates the need to set out and take down stringline on concrete paving operations. The 3D control system can use existing models, or it can create a new digital data model on site, which eliminates the need for having a surveyor create a geodetic data model in advance.

Wirtgen offers the AutoPilot 2.0 for the SP 15/SP 15i and SP 25/SP 25i models. It is also possible to upgrade machines with the new system, the company says.

VIDEO > Hilti TE 500-A36 is the first cordless breaker: Makes destruction easier, can be paired with cordless backpack dust collector

Hilti used the World of Concrete to debut what it calls the world’s first cordless breaker, the TE 500-A36.

The 36-volt battery powered tool uses the company’s Active Vibration Reduction (AVR) technology to reduce vibration by more than 30 percent. It weighs 17.4 pounds but an adjustable, ergonomic D-handle on the port side helps keep the operator comfortable and in control.

The TE 500-A36 hits with 5.8 foot-pounds of impact energy while cranking out 3,300 impacts per minute using SDS Max type bits and chisels. The chuck and dust shroud are the same as Hilti’s corded models, so you don’t have to go out and buy all new accessories to use it.

A power on/off button disables the tool to prevent the trigger from inadvertently getting depressed during storage and transport and thus draining the battery.

Since it wouldn’t be right to pair a cordless tool with a corded dust collector, Hilti also makes available a cordless backpack vacuum that you can use in tandem with the TE 500-A36. The dust collector is Table 1 OSHA compliant.

In addition to the usual moil points and chisels, Hilti offers a selection of clay spades, chipping tools and ground rod drivers for the breaker. For more information and a demonstration see the video above.

New Doosan DX62R-3 adds 6-ton reduced tail swing choice to compact excavator lineup

The reduced-tail-swing 59-horsepower DX62R-3 is the latest addition in the Doosan Infracore North America compact excavator lineup and was on display for the first time at the recent World of Concrete 2020 show.

“This is a sister to our DX63-3 conventional tail swing model,” says says Aaron Kleingartner, Doosan Infracore North America marketing manager. “The dig depth and reach are virtually identical on the two machines, so it gives a contractor a choice between a conventional machine that has a little more lift capacity for craning materials or reduced tail swing for tighter areas.”

With just 4.9 inches of side overhang, the 13,779-pound DX62R-3 allows users to work in confined areas with more flexibility to maneuver. The machine has a 13-foot, 6-inch maximum dig depth and maximum reach of 21 feet, 4 inches.

The quick coupler hydraulic piping kit now extends to base of the machine’s arm.

Doosan has also reconfigured its quick coupler hydraulic piping kit.

“We used to install it at the base of the boom, but now we install hard lines all the way to the base of the arm. It makes adding that option a lot easier,” Kleingartner says.

The design of the DX62R-3 builds on the conventional machine by adjusting the positioning of the excavator upperstructure to the undercarriage to reduce tail swing length. Moving the swing center forward extends the machine’s digging reach by 11 inches while maintaining the desired machine balance.

The unit has a 6.18 cubic-foot bucket capacity and an overall width of 6 feet, 6 inches.
