Atlas Copco’s new BG245 and BG375 (pictured) walk-behind trowels are designed to finish concrete in limited-access worksites and close to walls due to their compact bodies and light weight. The upgraded trowels feature an adjustable handle, a maintenance stand to ease servicing, and a centrifugal clutch for safe operations. The BG245 weighs 130 pounds and is 24 inches in diameter while the BG375 weighs 185 pounds and is 36 inches in diameter. Twist pitch controls allow the operator more control and feel of the blade angle on the concrete. Both trowels can be operated at variable speeds making it possible to do high-speed burnishing and low-speed, high-torque floating.
The Brokk 400 remote-controlled demolition machine features a large undercarriage for heavy-tracking applications like tunneling and mining and for enhanced stability when operating with dynamic attachments, including metal shears and scabblers. In 2014 the Brokk 400 was ugraded to feature a larger drive axis, rollers and sidetracks. It also has been equipped with a larger undercarriage with new tracks that are 10 percent longer than the original. This improves longevity for machines used in applications that require a lot of tracking and provides up to 60 percent greater stability when operating with heavier attachments.
The CP4133 chipping hammer offers increased durability, strength and ease of service. The hammer features a locking mechanism with four high strength .-inch bolts, a “D” handle with an outside trigger and extra safety mechanism, muffler assembly, and a simplate valve for smooth operation. The CP4133 is available in 3- inch or 4-inch cylinder stroke versions and a choice of bushing of .680-inch round chisel that rotates freely or .580-inch hex to prevent chisel rotation.
EDCO Magna-Trap Systems concrete grinding surface preparation equipment and tooling are specifically designed for the rental industry. EDCO offers the same surface preparation tooling across all EDCO Floor Grinders and Turbo Grinder product lines and increased application solutions through new tooling selections. The line is designed for consistency and simplicity in approaching surface preparation tasks and rentals and the OEM promises decreased risk of tooling burn out. The combined capabilities of the EDCO’s four core Magna-Trap tools – Dyma- Dots, Dyma-Segs, Dyma-PCD with Backing Segment, and Strip-Serts – are designed to solve most surface preparation applications.
Designed for smaller-scale surface preparation projects, General Equipment Co.’s SG12/E single-head surface grinder is powered by a totally enclosed, fan-cooled 1.5-horsepower electric motor. The SG12/E features a single rotating disc with a 12-inch-wide working width. Offering a top disc rotation speed of 250 rpm, applications for the SG12/E include grinding concrete surfaces, removing mastics, adhesives, epoxies and urethanes, breaking up deposits of grease and dirt, removing rubber carpet backing and industrial residues, and polishing more delicate terrazzo and marble floor surfaces.
The bull point chisel is designed for general concrete breaking and chipping. However, effective breaking requires that the chisel remain sharp to penetrate hard concrete. The new Makita 16-inch self-sharpening Bull Point bit for 1-1/8-inch hammers features an innovative design engineered to keep the bit point sharper longer than traditional bits. The bit features improved geometry for faster penetration and more efficient material removal. The self-sharpening Bull Point Bit is for use with 1-1/8-inch hex hammers, and general purpose demolition in brick or concrete, as well as for starting holes in concrete.
Minnich A-1 Series drills feature flat-proof tires for increased maneuverability, adjustable handles for operator comfort, easy-to-use controls and minimal vibrations to reduce operator fatigue. All models in the line are capable of drilling anywhere from 3 inches to 12 inches from the top of the slab. The A-1 series can be configured four different ways depending on the application: two wheel on-grade for more accurate drilling; one wheel on-grade for drilling from corner to corner of the slab; wall configuration for zero-clearance drilling; and upright configuration for vertical applications.
MK Diamond’s Manta III Core Drill Rigs are designed to core holes up to 14 inches in diameter in all types of concrete floors, walls, and ceilings. They feature a rack and pinion gear-system designed for excellent control of the drilling pressure and cutting speed. The control box with amp meter helps the operator control the cutting load. The MK-Manta III Core Drill is designed for use with five models of two-speed Milwaukee 15 or 20 amp motors that provide the correct cutting speed over a wide range of core bit diameters. Shear pin or friction clutch configurations are available.
Wacker Neuson has introduced two new motors for its popular HMS flex shaft vibration system. The M1500 and M2500 electric motors are lighter weight than previous models and are designed for extremely long service life with carbon brushes that last up to 500 hours of run time. The engines also feature double insulated construction with increased thermal capacity and a dual air filter. Wacker Neuson’s flex-shaft system allows contractors to combine a variety of flex shafts, ranging from 1.5 to 30 feet and vibrators heads that include diameters from one to 2.75 inches. The new M2500 motor is adaptable to all shaft and head combinations.
