Adva Cast 555 superplasticizer suits self consolidating concrete mixes for precast/prestressed Among new features and benefits for producers, the agent offers these manufacturer-cited benefits: (1) High segregation resistance. Its ability to tolerate more variation in water and cement content and aggregate gradation profiles broadens the window to lower cement factors, as it enables the producer to utilize less costly aggregates, including some that previously were not viable for SCC; and, (2) More flowable concrete at lower viscosity. The lower viscosity allows concrete to flow farther and more quickly to fill pieces, decreasing placement time and the number of placement locations for a given piece. In addition, the Adva Cast 555 technology allows for consistent control of SCC strength and air content. Grace Construction Products

Wellbraze and Well-Clad are alloy steel products developed to resist abrasion and impact in tough-wear applications, such as concrete plants and sand/gravel/rock crushing. The products are used in fabricating chute liners, hoppers, tumbling barrels, and conveyor parts.
Wellbraze is a (homogenous) solid sheet with high manganese and nickel content. The product work hardens (17-20 percent work hardening factor), so it gets tougher the longer it’s in service. Wellbraze can be welded with all low-hydrogen production welding processes (E7018, E9018, E11018, E12018 and 12018 manual electrodes). It can be drilled with ordinary high-speed drills. Material thicknesses up to 1 in. can be brake formed (with proper bend allowances). Available size ranges include ?-in. to 6-in. thickness; 48-, 72-, and 96-in. widths; and, 144-, 240-, 288-in. lengths.
Well-Clad is an impact and wearing, chromium-carbide overlay applied to what product developers describe as a ductile, easy-to-weld, easy-to-form, low-carbon steel substrate. The mild steel plate (0.12 maximum carbon) was selected to absorb impact resulting from heavy service. The composite material (mild steel backing plate with the hardfacing overlay applied by a proprietary arc welding process) can be rolled or press-brake formed without risk of separation. Well-Clad was developed for severe-wear applications. Wellington Alloys

The attachment suits contractors who routinely work in residential areas with confined yards. Either side of the concrete pump attaches to the company’s loader for better positioning. The hoses are then connected, and the concrete mix is fed into the hopper and pumped to the jobsite. The pumping hoses can be routed through small openings, under decks, through vegetation, around trees and buildings Û precluding buggies, loaders with buckets, wheelbarrows, shovels, or chutes.
Depending on hose length and diameter, and conditions such as slump, additives, and aggregate size and type, the attachment can pump mixes as far as 250 ft. horizontally or up to two stories vertically. With a high-flow loader, the pump can place concrete up to a maximum of 28 yd./hour. Using the manufacturer’s Remote Attachment Control, the operator can start the loader from the ground without having to re-enter and exit the cab. The attachment has several standard features, including a horizontal agitator that helps stir concrete and pulls it to the bottom of the hopper. It also comes equipped with an expanded metal walkway, a swiveling control panel, and a protective guard panel that strains larger objects from the concrete mix. Bobcat Co.

Manufacturer cites introduction of the world’s smallest ride-on model: the 320-lb., 13-hp MK8-75H Lowrider featuring twin 30-in. rotors and an edger system for finishing nearly flush to walls. It can also be equipped with finish or combo blades and float pans. The lightweight MK8-75H can be placed on concrete sooner than heavier machines and maneuvers in tighter quarters, passing through 32-in. doorways. Synchronized steering helps make the MK8-75H exceptionally responsive, product developers note, as a labor saver when used instead of multiple walk-behind trowels or complementary to larger ride-ons for edging work and accessing tight spots. Three rollers on its front guard ring enable the machine to finish within approximately ∫ in. of a wall. The MK8-75H is transported in the bed of a typical pick-up truck. MBW Inc.

COLOR BATCHING SYSTEM
An automated, enclosed, and dust-free mechanism with five moving parts, the company’s newest color metering system is capable of using powder pigments, though dry granular pigments are most commonly employed in four basic colors. From two shades of red, a yellow and a black, virtually any color is created. When the automation panel calls for color, the metering system selects dry pigment per a predetermined formula for each designated end-color, mixes it with water, then transfers that slurry to the mixer or truck. A rinse cycle between each batch prepares the system for the next color.
The color-metering system comprises bulk containers for the pigment granules and 4-in. screws with variable-speed electronic drive to carry pigment from the bulk container to the blending unit. For ready mixed producers, a stainless steel blender Û holding up to 500 lb. liquid or 250 lb. of dry color Û eliminates color contamination. It is suspended on three compression load cells that provide a digital readout in 0.1-lb. increments to the automation panel.
As the panel is the heart of the system, according to the manufacturer, updates are entered via modem whenever customer feedback warrants new data. Currently, the Allen Bradley PC batch panel stores up to 400 formulas and includes a Windows-type desktop PC with operator interface on the desktop. Soon to be unveiled is interface of this software with Command Alkon batch plant controls for total system integration. The system also includes a bagging option for color use at remote plants.

Responding to increasing demands of dealers and customers in the field for more lifting abilities, IMT has added two truck-mounted articulating cranes: the 52/380 and 72/516 series. These models nearly double the rated capacity of the company’s largest existing crane.
The business of handling precast concrete products played a major role in these models. IMT made the commitment to produce two new cranes that could handle typical loads, which company engineers acknowledge are getting heavier as applications evolve.
The manufacturer recommends a minimum 66,000 GVW chassis for these cranes. All of the crane parts are located above the base level in the parked position, which provides optimum fitting on the truck. The IMT articulating cranes feature the ability to fold and stow in a small area on the truck frame and do not interfere with the load-carrying area.
The 52/380 and 72/516 cranes are designed for two to eight hydraulic extensions. With eight hydraulic extensions, both models have a horizontal reach of 67.6 ft. and a vertical reach of 77 ft. The maximum lifting capacity for the 52/380 crane is 26,000 lb., while the maximum for the 72/516 is 35,500 lb. Both offer 360-degree continuous rotation.
The cranes can be equipped with hydraulic jibs as an additional option. These can give the operator an additional 43 ft. of horizontal reach and 38 ft. of vertical reach on the 72/516 crane. With the addition of a hydraulic jib, the 52/380 crane’s horizontal reach is 94.1 ft., and the vertical reach is 101.8 ft. The 72/516 crane equipped with a jib has a horizontal reach of 110 ft., and a vertical reach of 114.10 ft.
Both models come standard with wireless radio controls. The cranes also have wider-stance outriggers as a standard feature, as well as a regeneration system in the hydraulics to obtain faster speeds with all boom functions (inner, outer, and extension).
The IMT cranes offer the Electronic Vehicle Stability system as an option. The system monitors and adjusts stability, allowing the operator full capacity of the crane within the vehicle’s capability.
