Anxious chatter about supply chain constraints and uncertainty concerning the post-COVID era became exhausting to find among the contractors, manufacturers and numerous masonry experts at the World of Concrete trade explain held Jan. 23 to 25 in Las Vegas. Equipment makers appreciate been filling inform books, and corporations appreciate been looking to refresh and magnify their fleets because the immense spending from fresh federal infrastructure initiatives begins to translate into right initiatives, even as private building faces some economic headwinds.
“With a stronger economic system than anticipated, inflation doesn’t come down as rapid, and neither terminate interest rates and these sectors—residential and non-residential [sectors] accept damage,” acknowledged Ed Sullivan, chief economist for the Portland Cement Association. “However totally different sectors now not delicate to interest rates, appreciate infrastructure spending, is anticipated to explain up in a more meaningful skill this yr and subsequent,” he acknowledged, adding that a revitalized U.S. manufacturing sector—buoyed by the 2022 CHIPS and Science Act—is one more knowing house for building.
Caterpillar’s fresh CTL 265 features a redesigned cab intended to obtain long shifts rather more joyful. It is ready to deal with excessive-seek information from hydraulic attachments, such because the PC306 mulcher viewed here.

While PCA learned a decline in cement consumption of 2.9% in 2023, things are looking up a tiny for 2024, with a forecasted upward thrust of 1.4% in consumption. “In our mind, the extra unfavourable impact coming from excessive interest rates is partially offset by the stronger economic prerequisites,” explained Sullivan in a briefing to press at the trade explain.
More Pleased Cabs to Retain Operators
On the explain ground, there became a renewed sense among attendees that with supply chain concerns largely sorted and manufacturing up and running, fresh machines will be delivered promptly for the 2024 building season. For Caterpillar, there became loads of attention and buzz round its fresh compact observe loaders, the medium chassis 255 and the greater 265. The fresh gadgets feature automatic instrument attachment recognition and an operator’s cab with more products and providers and features than learned in earlier gadgets.
“[The new cab design] might be pushed by the lack of workers—at the same time as you can attract factual capacity and you wish deserve to retain them, one of the ways to terminate that is to present them with factual equipment that performs however might be joyful to be in,” explains Kevin Coleman, product supervisor at Caterpillar.
With redesigned hydraulics allowing the loaders to scamper greater instrument attachments and vitality thru more demanding projects, their role on the positioning has been slowly shifting from a hop-in, hop-out portion of equipment to a location the attach operators can also exhaust their total shift. Caterpillar also is bringing features previously viewed on greater machine cabs, equivalent to non-obligatory ventilated seats with heating and air suspension, in addition to rearview and sideview cameras, to its smaller equipment.
The 255 and 265 gadgets feature 64-hp engines—to contain beneath threshold for emissions after-treatment—however their unusual hydraulic systems enable them to scamper some of the most demanding attachments, including mulchers and totally different vitality-hungry forestry equipment. Both boast rob heights of 11 ft, allowing for loading into greater trucks.
A Original Generation of the Battery Wars
Contemporary innovations in pushing the limits of lithium-ion vitality has viewed battery-powered tools tackling many applications that used to demand corded vitality or gas.
Original battery lines from Milwaukee Software and DeWalt appreciate been on point to and accessible for demonstrations on the explain ground, with concrete rammers, concrete vibrators and concrete lower-off saws running off of fresh battery platforms. These projects, which on the total demand gas-powered tools, are now doable with batteries that can final the total shift.
Milwaukee’s fresh MX FUEL REDLITHIUM FORGE batteries bring longer runtime and extra vitality for more demanding applications. “What’s in actuality weird and wonderful about these is they’re in actuality pushing the limits of capacity,” explains Kelli Semon, product supervisor for Milwaukee Software.
Additionally fresh at the explain became Milwaukee’s fresh Supercharger for the FORGE batteries, allowing two batteries to be charged at the the same time off of a used 15-Amp circuit. Using Milwaukee’s OneKey Bluetooth accept entry to, the battery charger’s behavior will be adjusted by a smartphone, allowing even more battery chargers to fee, albeit more slowly, off a single 15-Amp circuit without tripping a breaker. Semon says this pliability enables for faster charging of a battery or two during a single shift, while more batteries will be charged overnight in a instrument crib.
Milwaukee’s fresh 70kg Rammer became accessible for demo at the explain. Powered by the fresh FORGE battery platform, it is designed to interchange used gas-powered rammers for house preparation.

One of the most demanding applications is the fresh MX FUEL 70kg Rammer, which runs on the fresh FORGE HD12.0 battery, delivering up to 25 minutes of continuous runtime. A instrument that on the total requires gas vitality, the 70kg Rammer also features a gyroscopic automatic shutoff, instantly turning off the machine if pointers beyond a certain attitude.
In the interim, DeWalt debuted its rechargeable Powershift line of 554 Wh batteries and accompanying cordless concrete tools at World of Concrete. Every battery weighs 11.5 lbs so while it is heavier than a battery for hand tools, it is sized to suit properly in concrete tools equivalent to its screeds and concrete vibrators. DeWalt also had a fresh excessive-rate charger that can recharge the 554 Wh battery in lower than one hour. Its product crew acknowledged two batteries can also successfully exchange one tank of gasoline for powering such tools.

Richard Cacchiotti, director of product management for the DeWalt line at Stanley Black & Decker, acknowledged 15,000 to 18,000 sq ft will be smoothed on one screed with one battery and the backpack vibrator in the line can consolidate concrete for four to 5 hours on one battery. DeWalt also showed attendees an adapter that enables the 20-60-V DeWalt Flexvolt batteries for exhaust in the 60V.
DeWalt is now not focusing on the 60V capacity of the batteries and 554 Wh makes for a 9.2 Ah pack. The strongest Flexvolt battery pack accessible now might possibly perhaps be 300 Wh/5Ah (15Ah at 20V Max), which makes the PowerShift pack an 85% increase in capacity. DeWalt expects the fresh batteries and tools to be accessible this descend.
