Komatsu America International Company
The PC95R-2 is an upgraded, 10-ton, compact excavator that is designed for utility, housing development and swimming pool contractors that work in confined spaces and require an excavator that can dig outside the area of its tracks. The excavator is powered by an 82.5-horsepower Komatsu 4D106-1FB direct-injection engine. A seven-foot, seven-inch arm provides a maximum digging depth of 14 feet, seven inches, and a digging reach of 23 feet, 10 inches. The bucket has a capacity of .24 to .56 cubic yards. Info 211
Expansion Seal Technologies new GripTight PE test plug allows pressure users to test PE pipe in minutes instead of hours, significantly reducing downtime and lowering installation costs. The new plug can be installed quickly and easily. It is simply slipped over the ends of the pipe and tightened by hand. Unlike conventional plugs that must be heated and fused in place, no special tools are required. The plug is designed to permit testing at two times working pressure and uses line pressure to seal more tightly to the pipe's inner diameter for a secure, leak-proof seal. Info 212
The American Directional Drill MCM-4000 is a mud mixing and cleaning machine that offers wide compatibility with any brand of directional drill to clean and recycle bentonite drilling fluid; while providing the same benefits of reduced mud use, longer component life and reduced disposal cost. The MCM-4000 can process up to 400 gpm, and its larger tanks can process and hold more mud to keep up with popular drills in the 50,000 to 80,000 lb class. Using linear motion shakers to separate sand, grit and other solids from drilling mud, screens can be angled uphill to precisely control how long the return fluids stay on the screen while providing drillers with the control they need to remove moisture for the driest discharge. A variety of shaker screens in different mesh sizes are available to match drilling conditions. MCM-4000 tanks hold 4,000 gallons of fluid. One tank, positioned beneath a linear shaker screen, accepts returned mud while the other tank stores cleaned drilling mud, and can be used to mix additional bentonite. Mud in the second tank is sent to a mud pump that can be integral with, or separate from, the directional drill rig. MCM-4000 machines use a new "four shear point" venturi mud-mixing system to ensure uniform mixing, without the clumps that can plug filters and valves. Info 350

Hitachi Construction Machinery Corp.
The Super EX230-5 excavator, the Dash-5 redesign of Hitachi's field-proven EX220 was recently introduced as a heavier, more powerful model, with more lifting capacity. At the heart of the Super EX230-5 is an advanced E-P hydraulic control system. It provides impressive versatility, allowing a wide variety of operations, such as digging, grading, finishing and materials handling with power and speed. Smooth multi-function operations and enhanced controllability, combined with an extremely comfortable cab, greatly increase machine productivity and enhance operator effectiveness. Traction force has been increased by 6 percent and grading speed by 15 percent. Four work modes enable the operator to select the best combination of hydraulic flow and swing/boom priority for the job. A large rotary rpm dial makes it easy to fine-tune engine output, using any of three power modes. The standard mode yields a maximum 156-hp. The high power mode boosts function speeds whenever the arm-in function meets resistance by increasing engine rpm 6.25percent and providing 168 hp to maximize pump output. The E mode is utilized in light-duty applications. The cab, measuring at 66x40, floats on six fluid-filled elastic mounts, and has a fully adjustable suspension seat. All controls are logically grouped and easy to read, even in bright sunlight. Info 218
The Typhoon mud mixer is a stand-alone, 9 hp Honda-powered unit designed to increase the production of any drilling system on the market. Mixing at 250 gpm with 28 inches of vacuum, clogging is practically eliminated. Typhoon will turn over a 500-gallon tank in two minutes as bentonite powder is literally inhaled out of the storage hopper. The well-mixed mud will not clog the pump and it prepares the hole for a quicker, easier pullback. Info 216

New BoreMaker HDD Motors Deliver Increased Field Performance
BoreMaker motors, an innovative new line from Intedyne, L.L.C., are proving themselves in the field. Operating in blue limestone and cobble near Dalton, GA. Contractor Pro Bore Inc. of Mableton, GA, was able to complete their pilot bore using a 2 7/8-inch Intedyne BoreMaker HDD motor with a 1.75 degree bend turning a 4 3/4-inch rock bit. The BoreMaker motor substantially reduced equipment repair costs.
BoreMaker is a complete series of low-flow horizontal directional drilling motors for the utility industry. The superior performance of these positive displacement HDD motors is derived from their proprietary power sections that deliver maximum power to the bit through a patented, sealed bearing assembly which reduces pressure loss across the tool.
Because the BoreMaker motors deliver higher torque at lower flow rates, they create new opportunities for contractors by enabling them to drill in hard formations with smaller rigs. Additional advantages that also improve profitability are longer service life, lower maintenance costs and less down time. Info 226

Komatsu Introduces New Power Shift Backhoe Loaders
Komatsu Utility Corporation continues to expand its line of products with two new backhoe loaders: the WB14OPS-2 and the WB15OPS-2. These two models feature Komatsu's new power shift transmission, Electronic Gear Management (EGM) and anti-theft mode for greater performance and versatility.
The new power shift transmission is electronically controlled with four forward and three reverse gears, and can reach a top speed of 25 mph. The operator can switch driving direction and gears during operation without power interruption or disengaging the machine.
"These new backhoe loaders are ideal for digging or loading applications when the front loader or long distance travel require continual gear changes," says Hank Yasuhara, Komatsu director of product marketing.
When the operation, condition or individual needs change, the operator can customize the gear selection to either automatic or manual mode by using two buttons near the steering wheel. Another button (kick down), located on the handle of the loader control 1st and 2nd lever, allows and gear to be selected without using the gear controls.
The EGM controls are positioned on the left of the steering wheel and have been designed to allow the operator to perform all functions without having to take his hands off the wheel. The special microprocessor fitted in the EGM not only manages the commands sent to the transmission, but also offers other important functions such as; system self-diagnostics, automatic connection/disconnection of the 4-wheel drive and activation of the anti-theft alarm using a PIN code.
Finally, the power and efficiency of the power shift transmission is increased by the use of heavy-duty type axles with planetary hub reductions and electrohydraulically operated differential lock. Maximum operator safety is achieved by the superior braking system and the oil immersed multidisc brakes can be independently operated by utilizing either foot pedal.
The WB14OPS-2 is 16,600 pounds, and 86 hp, with a maximum digging depth of 14 feet, 6 inches (with a standard arm), while the WB15OPS-2 is 17,394 pounds and 98 hp, with a maximum digging depth of 15 feet, 6 inches (with a standard arm). Info 242
