Chicago Pneumatic Construction Equipment now offers a new concept in its vibration equipment lineup with the launch of electronic pokers. The quiet, safe and efficient Vektor 12K electronic pokers provide high centrifugal force, making them suitable for use across a wide variety of high-to-low slump concrete applications.
Cutting, coring or drilling into concrete on a project site is risky business. Hitting an electrical line, conduit or other buried feature within concrete is not only extremely dangerous, it can also be costly, leading to work delays, emergency repairs and a loss of production. Even when as-built drawings exist, they may not be accurate or detailed enough to pinpoint the location of hidden conduits, electrical lines, rebar and junction boxes.
Liebherr's newest crawler concrete pump the THS 110 D4f-K features a maximum concrete output of 133 yd³/h (102 m³/h) powered by a six-cylinder engine an is equipped with a powerful pump unit, known for its smooth operation and powerful suction. An open hydraulic circuit guarantees reduced system maintenance requirements. Additional structural details also contribute to optimum serviceability. High importance was afforded during the design phase to ensure that wear parts could be replaced quickly and easily. The smooth surfaces of the pump housing are easy to clean and the shape of the concrete hopper, devoid of edges and projections, minimizes the accumulation of concrete residue and soiling. An extensive standard scope of delivery for the crawler concrete pump includes for example, a 500-liter capacity water tank with water pump, as well as a lockable toolbox.
Caterpillar’s PM620 and PM622 Cold Planers are half-lane milling machines that perform controlled full-depth removal of asphalt and concrete pavements in a single pass. They are powered by a Cat C18 ACERT engine, a turbocharged, 6-cylinder diesel engine that provides 470 kW (630 hp) of gross power, meets Tier 4 Final emission standards and is iso-mounted to reduce vibration and increase operator comfort. Turbocharged air-to-air aftercooling provides high horsepower with increased response time, while Automatic Engine Speed Control optimizes output to match the load, reducing excessive fuel consumption and wear on the engine. Approximate weights for the PM620 and PM622, respectively, are: operating weight of 33,330 kg and 33,900 kg; transport weight of 29,400 kg and 30,000 kg.
At 70 years of age and a lifetime spent in the construction industry, Greg Di Pietro has seen a lot of changes and worked with a lot of GOMACO equipment and control systems, slipforming thousands of kilometres of curb and gutter and sidewalk. The first was a GT-6000, purchased in 1972 by a company called Weldon McEachen. It featured the Analog system, a proportional control system consisting of a sensor, amplifier and servo valve.
Aquajet Systems has introduced its farthest-reaching unit, the Aqua Cutter 710V hydrodemolition robot. It’s the largest of its kind and offers exceptional horizontal, vertical and overhead reach — as high as 23 feet. The 710V comes equipped with Aquajet’s hallmark ceramic nozzles that last as much as 79 percent longer than standard steel versions. Its design makes it suitable for a wide variety of concrete removal tasks, such as renovation and bridge and road repair.
GOMACO successfully introduced the revolutionary GP3 slipform paver with the ability to pave up to 30 feet (9.1 m) wide last year at World of Concrete 2016. It was the first in a totally new line of GOMACO pavers with next generation technology and it has quickly earned the respect of concrete paving professionals. This year, at CONEXPO-CON/AGG 2017, GOMACO introduced the next paver in the series, the GP4, with the ability to pave up to 40 feet (12.2 m) wide. It features all of GOMACO’s latest technology with a Smart Telescoping Frame, Smart Pivot Arms, Extreme Steering capabilities, and more. The GP4 was just one of 14 machines GOMACO had on display at CONEXPO-CON/AGG 2017.
With the handheld outdoor power equipment industry’s first electronically controlled fuel-injection system, theincreases power by 17 percent and cutting speed by 15 percent while only increasing weight by six percent, as compared to the STIHL TS 420.
GOMACO Remote Diagnostics (GRD) is proven in the field by GOMACO contractors. GRD is more than telematics, giving owners the visibility of how, when, and where their equipment is being used. It’s a powerful extension to GOMACO’s existing service capabilities. It allows technicians a diagnostic review of a GOMACO machine from corporate headquarters in Ida Grove, Iowa, USA, at the owner’s shop, or on the job site. GRD will transmit G+® settings, configuration and fault history for an immediate and complete diagnosis. GRD also allows software updates, fleet management, service indicators and so much more.
Aquajet Systems has introduces the world’s smallest hydrodemolition robot, the Aqua Cutter 410V. The model combines the compact size of the Aqua Cutter 410A and the innovative mast system of the Aqua Cutter 710V, giving it versatility to work in tight spaces with extended reach in horizontal, vertical and overhead applications. The 410V’s design makes it suitable for a wide variety of concrete removal tasks, such as renovation and bridge and road repair.
Con Cast Pipe, a manufacturer of precast concrete drainage products including concrete pipe, manholes, catchbasins, and box units, as well as a wide range of bridge and specialty precast products in Canada, has announced the recent purchase of Hy-Grade Precast Concrete in St. Catharines, Ontario. Due to their outstanding reputation in the Niagara community, Hy-Grade Precast Concrete will continue to operate under the Hy-Grade name and become the third Ontario manufacturing facility for Con Cast Pipe.
Toronto’s Ten York project is a residential highrise building that will soar 65 storeys and contain 694 units when complete. Located at the busy intersection of York and Harbour, near the waterfront and overlooking the Gardiner Expressway, there are a number of challenges to be faced for concrete work. In this case, the use of traditional truss tables was not permitted because of the nearness to the Gardiner. Crews had limited space on the ground for staging and storing of material, shear wall construction restricted movement of shoring material through the building, and a ten-foot deep transfer slab is suspended 40 feet above the floor below.
Now part of the Terex Materials Processing Systems (Terex MPS), Terex Bid-Well announces a strategic alliance with Terex MPS sales and support to grow its equipment sales and service beyond the U.S. market. The concrete paving equipment manufacturer will leverage synergies with the Terex MPS sales and certain distributor locations to significantly expand Terex Bid-Well’s global customer sales and support capabilities.
