The Boxer Brute TRX features a compact 44-in. _ 70-in. footprint and 900-lb. operating capacity. The 9-in. _ 42-in. rubber tracks are reportedly designed for optimum traction and flotation with minimal compaction. An operating weight of about 2,450 lb. (with operator), distributed over a 331-sq.-in. ground contact area per track, translates to 3.7 psi of ground pressure, yet ample traction on slippery surfaces.
The machine is built to handle over 50 universal compact utility attachments, including a 36-in. auger and 48-in. trencher. Brute’s standard quick-attach system enables the user to switch from bucket to forks to auger or other tools, the manufacturer notes.
The model is powered by a Kohler Command Pro 27, a fuel-efficient and environmentally proven 27-hp gasoline engine. A two-pump, 3,000-psi hydraulic operating system develops 12.6 gpm of hydraulic flow to run the machine’s auxiliary and propulsion systems. Power from both systems is combined and redirected by valves to support the system in need. An intuitive creep valve can be adjusted by the operator for best results. Compact Power

Mechanical splicing system joins two sections of rebar by interlocking them with molten-steel filler. The rebar splice is a butt splice (metal filled, not welded) that produces a joint with essentially the same mechanical properties as a continuous piece of rebar, the manufacturer affirms.
The process involves an internally grooved sleeve working in conjunction with rebar deformations to develop strength and consistency. The rebar connections suit critical structures that require high safety margins, such as blast-resistant facilities, pressure vessel applications, nuclear reactor containment structures, and in-situ splicing. The splices work on all standard grades of reinforcing steel with deformations.
Capable of exceeding 150 percent of minimum specified yield (Grade 60), the system meets ACI 318, ACI 349 and ASME 359 requirements. It is also designed to meet or exceed many major building code requirements. Erico

EPOXY COATING COLORANTS
The Series 28 line of stable colorants for epoxy floor coatings prevents additive float and flocculation that cause colors to vary depending on when in the cure cycle they are applied. Pigments and other solid additives in freshly applied epoxy floor coatings tend to stratify, the manufacturer reports, causing a continuous drift in color until the applied coating sets up. To remedy that situation, the new colorant line consists of 40 standard single-pigment dispersions and custom blends in a highly stable, 100 percent-solids, epoxy resin vehicle. Reactive with all epoxy resin formulations, the new stabilized dispersions also increase the original pigment’s opacity by 50 to 80 percent, as special processing breaks down pigment agglomerates into individual particles that are wet-out in suspension to prevent reagglomeration. Series 28 epoxy colorants are pourable and pumpable liquids that blend rapidly and uniformly with epoxy base resins; they are available in five-, 30-, and 55-gal. containers. Ferro Liquid Coatings

According to the manufacturer, the IT38G Series II Integrated Toolcarrier Û a medium wheel loader-based machine Û has been redesigned to enhance versatility, productivity, and visibility by providing sight lines to the quick coupler and work tools, plus increasing the number of available attachments. A bucket size range spanning 2.75 to 3.5 yd. enables customers to closely match material density and bucket size for optimum productivity. In addition, a full range of work tools is offered. The machine also maintains key features including 180 net horsepower, parallel lift linkages, and integral quick couplers to handle a wide range of material-handling and digging tasks.
Whereas the IT38G Series II previously had quick coupler pins actuated by a third lever, delivering pressure to move the coupler pins through a third valve, the machine now has an electro-hydraulic system for the quick coupler. The new system, electrically actuated with a switch in the cab, delivers pressure to the coupler through the brake system. Consequently, the third lever and valve are available for additional work tool functionality, such as a top clamp or a rollout bucket. A fourth function switch, located next to the quick coupler switch on the implement pod, can be added for work tools having multiple functions, such as rollout buckets with thumbs. Strategic structural changes have increased full turn static tipping load by 14 percent to 19,106 lb. Caterpillar
