January 30, 2017 – Tens of thousands of concrete and masonry professionals from around the globe descended upon the Las Vegas Convention Center for the 2017 edition of World of Concrete, which took place from January 17 to 20 in Las Vegas, Nev.
Rock to Road checked out some of the latest technologies and products that were on display at the show for the road building and aggregate industries. Here’s what we found.
Dexter + Chaney
Dexter + Chaney unveiled its new Spectrum Ticketing solution as part of its comprehensive Spectrum Construction Software suite. Spectrum Ticketing is a unified web, mobile and scale house solution for bulk material weight ticketing, providing material haulers and handlers with a cloud-based system to more efficiently and accurately manage their materials and material tickets. It is completely integrated with Spectrum’s materials management and accounting solutions, as well as inventory, job costing, project management and other areas of Spectrum functionality. Spectrum Ticketing’s web portal automatically updates and provides real-time data for when materials are collected and tickets are issued.
The Terex Advance FD4000 Front Discharge mixer truck’s lighter weight rear tandem axle design allows customers to efficiently run either super single or dual tires, increasing its flexibility to be used in multiple markets. The truck’s Meritor DualTrac rear axles feature disc brakes to reduce stopping distance. The axle design increases bearing life by effectively repositioning wheel bearing loading similar to that of dual tire configurations when used with single 0-0.56-in (0-14.2-mm) outset wheels. The new rear axle offers a full 40,000-lb (18,144-kg) rating with no de-rate necessary. The mixer truck is powered by a Cummins ISX 12, 385-hp diesel engine delivering 1,450 ft-lb of torque. The engine also offers power and torque ratings of 350-hp/1,450 ft-lb and 425 hp/1,550 ft-lb. Customers can opt for the MTU Series 1300 (DD13) engine with 350-, 380- and 450-hp packages to meet application demands. The truck can also be powered by a Clean Cummins ISX-12G compressed natural gas engine.
Reliable Mix Concrete Equipment
Reliable Mix Concrete Equipment’s RMX 100 Batch Plant requires no cranes, ramps or special site prep and is designed to be set up in 15 minutes. It has production capabilities of 100 cubic yards per hour. The gravel and sand bins have a capacity of 12 cubic yards each, four shear beam load cells, clam gate (air or hydraulic) and a vibrator frame. The cement silo has a single or optional twin silo; 30-ton total capacity; and two 10” discharging augers. The delivery conveyor features a Chevron 24” wide belting; rollers and idlers; adjustable 10” belt tensioning tail pulley; a 12” diameter head pulley; and a 10-hp electric motor with gearbox. The control panel has a NEMA 4 rated, weather proof enclosure. The air compression system has an 80-gal. capacity with air dryer and a 10-hp motor. The chassis features include: single axle dual wheel; axle 23,000 lb. rating air bag suspension; tires are 255/70R x 22.5; air brakes/maxi posts; and DOT standard lighting.
The SP 15i features Tier 4 interim emissions technology, and is a multi-purpose machine that lays curb and gutter, barrier, sidewalk, V-ditch, special applications and slabs. It can be quickly configured on site for left- or right-side pouring. The SP 15i accepts AutoPilot technology from Wirtgen, a GPS-based system that ensures highest precision and optimum efficiency in slipform paving, regardless of whether straight profiles, highly complex curved paths, or closed profile configurations need to be placed. The paver has a maximum paving width of 6 ft., maximum barrier/parapet placement height of 4 ft., 3 in., and a maximum operating weight of 28,500 lb. It has best-in-class trimming capacity, quick on-site changes for left or right side pouring, unsurpassed job site mobility, and pours the tightest, smoothest radius in the industry with all-track steering and positioning.
Gomaco’s proprietary and exclusive G+ control system now offers a G+ remote control for hands-on machine control at all times. The new G+ remote control features a 4.3” graphic display screen that shows the run functions of the machine, the same information that is normally viewed at the operator’s console on top of the paver. Most paver functions are included on the remote and are controlled with easy to operate and durable dials or switches. It also gives the operator individual control of each leg of the paver with automatic/manual adjustments for elevation and steering.
The lightweight remote control allows the operator to comfortably work from the operator’s platform or from the ground. The G+ remote control has an emergency stop button and an alert horn on the remote that are always within reach for quick access.
Mack Trucks introduced Mack mDRIVE rolling start and auto neutral, two new features designed to improve the jobsite performance and safety of trucks equipped with Mack’s mDRIVE and mDRIVE HD automated manual transmissions. Both features are standard on all Mack mDRIVE and mDRIVE HD transmissions. Mack mDRIVE rolling start allows drivers to shift the transmission into drive without pressing the truck’s service brakes. This eliminates the possibility of creating a bump in the paving surface, which is a critical benefit for paving applications. Several construction applications, including concrete mixers, rely on remote throttle controls. By automatically shifting the mDRIVE into neutral when the parking brake is set, Mack mDRIVE auto neutral helps improve jobsite safety by reducing the possibility of the truck moving due to throttle application.
Allmand Bros. Inc. has expanded its product offerings into the portable air compressor market. The Maxi-Air portable air compressor’s heavy-duty, over-sized rotary screw air end provides consistent, high-pressure air volumes at low RPMs for enhanced fuel efficiency. The Maxi-Air comes in two models, the MA185 and MA400, with free air delivery of 185 scfm and 400 scfm, respectively. Both models achieve a maximum working pressure of 120 psi.
CASE Construction Equipment introduced the all-new G Series wheel loaders, spanning seven new models. These loaders bring the entire product line to Tier 4 Final compliance featuring selective catalytic reduction engine technology. The seven models offer gross horsepower ranging from 141 to 347 hp; bucket capacities from 2.1-2.6 cu. yd. to 5.25-6.25 cu. yd.; and breakout force from 20,937 lb. to 56,245 lb. The G Series wheel loaders feature the latest in electro-hydraulic controls, ergonomic design and operator interfaces, including a solid-state controller that provides software control over electrical power distribution and basic vehicle.
Kaeser Compressors’ M27 Mobilair rotary screw compressor offers free air delivery of 92 cfm and a working pressure of 100 psig. It has a 21-hp Kubota D1105-B diesel engine with a full load speed of 2,850 rpm and an off load running speed of 2,100 rpm. The compressor has a 10.6-gal. fuel tank capacity. It weighs 1,224 lb. and its dimensions are 119” x 49.5” x 51.25”.
Trimble Construction Logistics’ upgraded Drum Rotation Sensor offers ready mix fleets insight into their equipment to ensure they deliver a quality product. Its features separate sensors and cabling, allowing them to be replaced independently; LED status indicator lights; and heavy-gauge stainless steel mounting brackets that are more resistant to impacts that could bend previous versions out of alignment. The new mounting brackets also make the sensors more resistant to damage caused by the cleaning and washing of the mixing drum.
