Product Focus: Concrete equipment – November 2008

Combihammer reduces vibration
Perform concrete drilling applications in the 3/4- to 6-inch-diameter range with Hilti’s TE 80 ATC-AVR combihammer, which has a 1,700-watt motor. The combihammer features Hilti’s Active Torque Control, an electronic rapid cut-out system that disengages the tool drive if the drill bit sticks, and Active Vibration Reduction, a mass damper system that absorbs vibration in the tool’s longitudinal axis.

Handle rebar up to No. 6 grade 60 with portable machine
Cut and bend 3/4-inch rebar with Fascut’s Model FS-600 portable machine, which can be carried by two people. The self-contained electric hydraulic unit cuts bars to length and plugs into a standard 110-volt outlet.

Concrete pump comes with range of useful features
Handle low cement/sand mixes with Multiquip’s Mayco LS600 concrete pump, which has a volume output of up to 60 cubic yards with a concrete piston face pressure of 1,100 psi. Standard features include hydraulic surge brakes, true reverse shuttle tube pumping and a full flow shuttle tube concrete valve.

Saw’s flush cutting feature reduces finishing work
Cut to 16 inches indoors with Husqvarna’s K3000 Cut-n-Break electric power cutter saw. Useful for cutting window and door openings, crack chasing and joint repair, the saw features a sliding guard for flush cutting.

Air powered saw cuts to 4-inch depth
Cut concrete, asphalt and stone with Chicago Pneumatic’s CP 0044 saw, which has a 4-horsepower motor that operates at 4,800 rpm. The direct drive motor offers consistency in speed and torque with a reduction in maintenance. The 28-pound saw requires 43 cfm of air and comes with 12- and 14-inch-diameter cutting blades.

Breakers feature ergonomic improvements
Perform concrete and asphalt breaking applications with enhanced operator comfort with Atlas Copco’s TEX line of pneumatic handheld breakers, which features noise dampening polyurethane silencers and a low center of gravity to reduce operator fatigue. Both the 34-pound TEX 140PS and the 42-pound TEX180PS have a standard two-step trigger that enables the operator to fully control the chisel when starting a cut.

Drill to 18 inches deep with Combo unit
Decrease setup time with E-Z Drill’s Model 240B SRA Combo drill system, which does not need to be anchored to the concrete. The Combo drill performs both rock and core drilling applications, eliminating the need for a separate drill system. The conversion process can be completed quickly on the jobsite with few tools. The pneumatic core drill uses a three-speed motor – 400-, 900- and 1,600-rpm – and requires 77 cfm of air.

Increase productivity, reduce labor with extruded curb machine
Eliminate labor intensive form work required when placing curb by hand with Power Curbers’ 150 and 440-XL machines. The units force concrete or asphalt mix through a specially designed mold to produce a pre-shaped, free standing curb.

Concrete chainsaw has redesigned features
Make square corners with no overcuts and plunge cut to 14 inches with ICS’s 680GC gas powered 80-cc concrete chainsaw, available with 12- or 14-inch guidebars. Redesigned airflow reduces engine temperature by 100 degrees compared to previous models, and robust starter components and a digital coil ensure reliable starts.

Trowel line available in range of sizes
Choose from 24-, 36-, 46- and 48-inch-diameters with Stone Construction Equipment’s line of Smooth Operator Power Trowels. Featuring a cast iron spider, rotating stabilizing ring and infinitely variable blade adjustments, the trowels also have a one-piece precision machined gear case with hardened worm gear and tapered roller bearings for trouble-free operation.

Slipform pave in tight locations with narrow curb machine
Choose from right or left hand pour with the Miller Formless M-1000 curb machine. The unit features a narrow width to enable vehicles and equipment to pass during operation. Useful for site work, remove and replace applications or commercial jobs, the M-1000 features fast set-up, simplified loading and a high degree of maneuverability.

Walk-behind trowels deliver precision and speed
Save time on the jobsite with Ingersoll Rand’s WT-Series of walk-behind trowels, which feature quick-change blades and precision controls for enhanced productivity. A screw pitch control adjusts the blade angle to produce a flatter end product, and a quick-release safety lever stops the trowel instantly.

Gas powered vibrator comes in backpack or handheld models
Eliminate the hassle of an electric cord with Minnich Manufacturing’s gas-powered flex shaft vibrators. Powered by the Honda GX35 Mini Four-Stroke engine, the vibrator delivers 1.5 horsepower and 8,000 to 9,000 rpm, which is transferred to the head through Minnich’s direct drive system.
