A floating snow wing mast?
If you’re plowing snow this winter, chances are the road you’re on is not perfectly contoured. In fact, it’s probably pretty much beat up – with dips, ruts and possibly breaks – topped off, of course, by snow- and ice-covered obstructions just prime for costly municipal insurance claims running rampant throughout North America. Responding with up to 13 inches of float instantly adjusted in the wing’s toe, the Smart Link rotational floating wing mast from Henderson Products provides conformance to varying road conditions, as well as the elimination of both toe dig and the binding associated with conventional mast/slides. According to the manufacturer, impact forces are reduced by as much as 70 percent over traditional front-wing mast configurations, which require additional bracing. Converting easy from existing wing systems, the Smart Link has a low-profile design providing full access to the engine compartment and a clear line of vision for the driver. A large access hole in the front makes maintenance easy. A locking pin secures the wing when not in use.
Excavator range goes big on compacts
When the king of big yellow iron, Caterpillar, moved into the compact equipment market in the 1990s, it triumphed the future role of the original equipment manufacturer (OEM) as a full-range supplier. No longer were Caterpillar and other large OEMs willing to concede the compact market to niche players. Well, with its recent compact excavator product introduction, Caterpillar has one taken step further – a little step, that is. Three models ranging up to 2.7 metric tons in operating weight include Caterpillar’s foray into the “micro” market. Easily transported from site to site on a trailer behind a van or pickup truck, the 300.9D model weighs in at just 2,061 pounds – less than one metric ton – and has an overall width of only 28.7 inches for easy movement through a standard doorway. The 18.4-horsepower, diesel-powered excavator leverages a twin gear pump hydraulic system for maximum bucket breakout force of 2,000 pounds and stick breakout force of 1,011 pounds. Specifically to work with this model, suited to demolition contractors working in confined spaces, Caterpillar will be introducing a new H25 compact breaker. Maximum digging depth is 69.4 inches and maximum excavation radius is 121.7 inches. At the same time, Caterpillar introduced the 301.4C excavator model ranging 2,921-3,340 pounds in operating weight and the 302.7D CR maxing out at 5,886 pounds with a full cab. The latter is Caterpillar’s smallest compact radius excavator, offering zero tail swing when equipped without counterweight.
Tractors built specially for scrapers
John Deere has unveiled three track models – the 9460RT, 9510RT, and 9560RT – as its new 9R/9RT Scraper Special Series Tractors. The new lineup also includes three wheeled models (9460R, 9510R, 9560R). The full line is equipped with a fuel-efficient, high-torque IT4 13.5L PowerTech PSX engine featuring 460 to 560 horsepower. The 9460RT, 9510RT, and 9560RT are equipped with the Durabuilt 5500 Series Scraper rubber track in a 30-inch width. The functions and features formerly located on the right-hand console were relocated to the redesigned CommandArm, including a new 7-inch color CommandCenter display. The CommandArm provides fingertip controls of key tractor functions, including throttle, transmission speed and direction, and selective control valves. Additional adjustments and configuration settings are made on the optional touch-screen capable GreenStar (GS3) CommandCenter display.
Upgrades boost productivity, performance
New features on the Caterpillar D9T Track-Type Tractor include enhanced operator safety, comfort and convenience, while also refining performance and productivity. The machine is powered by a Cat C18 engine with ACERT Technology, rated at 410 horsepower with an operating weight of more than 110,000 pounds. A low-effort electronic dozer control handle gives the operator control of all dozer functions with one hand. An optional Automatic Ripper Control keeps the drawbar load constant and minimizes track slip. In addition, Automated Blade Assist uses blade-pitch presets to simplify positioning, and an optional auto carry system automatically adjusts blade load during the carry segment. The new Dynamic Inclination Monitor provides readouts of the tractor’s pitch angle and side-to-side slope, and a new operator-presence system locks out the power train and hydraulic system to avoid unintentional machine movement.
Automatically change crown while paving
Terex Corp. will exhibit its Bid-Well concrete paving equipment – the 4800 bridge paver and 2418 work bridge – at World of Concrete 2012 in Las Vegas this month. With standard paving widths exceeding 170 feet, the 4800 paver display unit will be set to 36 feet wide. A new style fogging system features all poly tubing to increase up-time and individually controlled spray nozzles to direct the fog where it’s needed. A new skewable power crown adjuster enables operators to automatically make changes to the crown when paving bridge decks at the skew angle. Featuring two new Evaporative Emissions (EVAP) compliant gas engines the show machine will display two-leg options available to paving contractors: a swing-leg design for zero-clearance paving; and a pivot-leg design for paving cross slopes of 6 to 8 percent.
Right-side, left-side slipforming
GOMACO Corp.’s new 4400 barrier machine for right-side and left-side slipforming will be at World of Concrete. Built specifically for barrier applications, it features a high-capacity cooling package on the engine. The manufacturer’s proprietary G+ control system makes the machine capable of operating in multiple languages. The 4400’s design concept was built around a left-side and right-side slipforming capable machine with symmetrical steering and minimal set-up changes for switching profiles from side to side. The U-shaped platform, which features vibration insulation and a side to side sliding control console, accommodates right-side and left-side pour and provides a 360-degree view of the entire paving operation.
Crush rocks, concrete onsite
MB America’s crushers are excavator buckets with an internal hydraulic jaw-crusher system that crushes rocks, concrete and any other hard material onsite, directly into the bucket. The machine also crushes reinforced concrete, returning both clean rebar and crushed material ready for recycling. Because the crusher bucket is used in conjunction with an excavator, it can be used in tight spaces and is easily transported. Four models are available and may be used on an entire range of excavators, from 9 tons and up.

Handles demanding compact jobs
The Chicago Pneumatic line of seven forward and reversible asphalt plates range in operating weight from 344 pounds to 1,111 pounds, and boast centrifugal forces ranging from 7,875 pounds to 13,488 pounds. With hydraulic steering, the machines are available with gas-powered Honda engines or diesel-driven Hatz engines. The wear-and-tear resistant plates have heavy-duty frames and engine covers that protect vital components. The bottom plates are constructed from wear-resistant Hardox 400 steel with a hardness of 400 HBW. An electric start on the MV480, the heaviest model, boosts efficiency on jobsites.
High lift capacity, enhanced stability
The Cat PL83 pipelayers replacing the 583T, has a rated lifting capacity of 160,000 pounds – a 14-percent increase over the previous model. The PL87, replacing both 587T and 587R, has a rated lifting capacity of 214,000 pounds, for a 6-percent boost in lifting capacity. Both new models use the Cat C15 ACERT engine, with a net horsepower rating of 310 horsepower in the PL83 and 366 horsepower in the PL87. The increased lifting capacity for the PL83 and PL87 results from undercarriage and counterweight changes. The track roller frame on both machines has been lengthened and the rear idler repositioned, yielding higher lift capacity and enhanced stability when the machines work on slopes.
Clamp-on snow blades
Worksaver’s new clamp-on snow blades are ideal for compact tractors with non-quick-attach buckets, the manufacturer says. The snow blades are designed to install easily and to remove with a chain and turnbuckle system. The attaching frame slides over the bucket cutting edge and the frame extends under the bucket bottom for complete support of the system. The snow blade features a 3/8-inch by 6-inch cutting edge of 1044 steel and the ability to angle right or left. The clamp-on snow blade is available in 5-foot and 6-foot models.
