The PRO12.3EFI also features Kohler’s patented Accu-Fill angled side-fill design.
SandHog Super Elbow is an alternative to metal fitting and hose-type unloading configurations.
Installed at all bend points, it offers abrasion resistance, allows for side unloading as well as rear unloading, and ships standard with a choice of four cam-style configurations. According to the company, the new elbow incorporates a spherical pocket design that traps a small amount of product causing the discharged product to wear against itself instead of the fitting wall. Abrasive material is typically discharged to the rear of the trailer to avoid as many bends as possible.

Updated with a Tier 4-Final CEGR engine, the 74-horsepower TR270 CTL has 7,270 pounds of breakout force, 232 lb.-ft. of torque, and 24.2 gpm of hydraulic flow. Operating weight is 8,270 pounds, and rated operating capacity is 2,700 pounds. The T4-F solution uses cooled exhaust gas recirculation (CEGR) with a particulate matter catalyst, which is made up of a diesel oxidation catalyst (DOC) and a high-efficiency flow-through filter.
GOMACO G+ Connect is a CAN-based network using proprietary software to connect all control systems on a GOMACO paver. This includes all electronics and hydraulics, as well as machine control technology.
According to the company, its 488-horsepower B50D is the largest model sold in North America. Bell trucks feature a sealed switch pad, which is designed to provide fingertip control of 90 percent of the truck’s functions. An on-board weighing system, visible to both driver and loader operator, is standard, and an inclinometer, says Bell, protects against rollovers during dumping. Other features include automatic retarding and traction-control differentials.
Seven 500 Series skid steer and compact track loaders have been upgraded with Tier 4-Final engines: S510, S 530, S550, S570, and S590 skid steers; and T550 and T590 CTLs. The loaders do not require a diesel particulate filter because the engines use a specially designed engine combustion chamber that reduces the amount of particulate produced, Bobcat says. The new engines produce between 4 and 12 percent more torque than the Tier 4-I versions.
The Caterpillar 966M, 966M XE, 972M, and 972M XE wheel loaders have Tier 4-Final ACERT engines and XE advanced power trains, which Cat says results in 25 percent lower fuel consumption on average over traditional torque converter machines.
The XE power train also features a two-pedal configuration, and the 972M XE is designed to be a 3-pass match for many of the larger on-highway trucks used in North America.
Caterpillar 770G and 772G off-highway trucks have nominal rated payload capacities of 40 and 52 tons, respectively, and use Cat C15 (770G) and C18 (772G) engines, with net power ratings of 477 (770G) and 550 (772G) horsepower.
Available in Tier 2/Stage II, Tier 3/Stage III, and Tier 4-Final/Stage IV configurations, the engines can be programmed to achieve the customer's specific fuel economy goals, Caterpillar says. Two programmable modes are available: Economy and Adaptive Economy.
