Wacker Neuson line expanded with two new generators

Wacker Neuson is expanding its mobile generator line upwards, adding 180 kVA (prime) and 240 kVA (prime) sizes. These generators feature the same design philosophy Wacker Neuson has incorporated in its smaller mobile generators: compact, robust construction, lowest in class sound emissions, superior motor starting, user friendly operation and service, and a broad range of factory installed options. In addition to new clean burning Tier III engines, standard features such as 115 percent fluid containment, crankcase oil vapour recovery system, and no mess oil and radiator drain hoses make these new Wacker Neuson models environmentally friendly. Wacker Neuson engineers designed these generators from the ground up, mating the new John Deere Tier III engines to properly sized, high efficiency Mecc Alte alternators to ensure that full engine potential is achieved for maximize power output and fuel efficiency. Both models come standard with integrated, long run fuel tanks that are 115 percent fluid contained; at 100 percent prime kW output, the G 180’s 300-gallon fuel tank provides 28 hours of run time while the G 240’s 400-gallon tank provides 30 hours of run time.

Komatsu Adds PC138USLC-2 to its Fleet of Near Zero Tail Swing Excavators

For increased power and performance in large quarry and heavy construction applications, Komatsu America Corporation (KAC) introduces the 651 hp, 251,000-lb PC1250-7 hydraulic excavator. The PC1250LC-7 replaces the company's P1100LC-6 as its flagship excavator for the construction market.

The PC1250s powerful Komatsu SAA6D170E-3 engine increases hourly
production by up to seven percent over the PC1100LC-6. The engine features an electronic controller and governor that fully complies with EPA Tier II air quality regulations. The PC1250LC-7 incorporates Komatsu's patented OLSS open-center, load-sensing and engine speed-sensing hydraulic system with four variable capacity pumps designed to enhance the machine's speed and

Two working modes, plus a heavy lift circuit allow the operator to match machine speed and power to the job. A unique two-mode boom setting allows the operator to electrically select a smooth mode for fine work and a power mode for heavy-duty applications.

Built to be a Low Cost Producer

New engine oil and filter change intervals are extended to 500-hours from the 250-hour interval recommended on the PC1100LC-6. The replacement interval for the hydraulic oil has been extended to 5,000 hours. In addition, the backhoe is equipped with a new wiring harness, DT type connectors and heat proof covering. These new features increase the reliability and durability of the
machine while reducing owning and operating costs.

The PC1250-7 is designed to reduce operating costs by extending
component life cycles. New hydraulic piping offers heat proof O-rings and face seal joints for added durability. The boom and arm offer increased section size and plate thickness, as well as continuous two-sided groove welding for maximum strength and reliability in rugged digging conditions.

The new Equipment Management Monitoring System (EMMS), accessed
through the color monitor panel in the cab, has the capability to schedule required maintenance and perform onboard diagnostics. Machine abnormalities are maintained in an electronic memory.

An optional Vehicle Health Monitoring System (VHMS) provides self-contained diagnostics, a preventive maintenance scheduler, gauge panels with operator warning override and downloadable machine performance history. Reduced costs and troubleshooting time, increased machine availability and reliability, as well as extended component life are the direct results of the VHMS monitoring system.

The PC1250-7 has fewer welds in the lower X frames and features
increased plate thickness for years of trouble free operation.

Automatic track tensioning and heavy guarding for the dual travel motors that power each track are standard on the PC1250LC-7. Travel motors are enclosed within the width of the track shoes for even further protection.

Operator Comfort Features

The PC1250-7's new, spacious operator's cab provides a comfortable work environment designed to maintain high operator productivity. The pressurized cab reduces noise levels 4 db(A) lower than the PC1100LC-6 and keeps dust and other particles from the cab's interior. The viscous damping mount system helps to minimize noise, shock and vibration in rough working
conditions. The inclined dashboard, one-piece-right-hand window, and spacious ceiling hatch increase visibility to all sides of the cab. The cab also is equipped with multi-adjustable seat and large-capacity, electronically controlled AC/heater/defroster systems to sustain operator comfort in any weather.

Versatility Is Key

Komatsu will offer the PC1250-7 in five different arrangements. The regular PC1250-7 features the standard length 21'1" track frame and 29'10" G.P. boom, and three different arm lengths. This configuration meets many general excavating requirements. Next, the PC1250-7 is configured with the 24'3" track frame and the 29'10" G.P. boom. This arrangement is perfect where additional flotation or maximum craning ability is required. The PC 1250-7 is further built with a standard length 21'1 track frame, a 25'7" reinforced boom and a reinforced 11'2" arm.

Top loading off road dump trucks is the specialty of the PC1250SP-7. The SP (super production) has a standard length 21'1" track frame machine, a 25'7" reinforced boom and a reinforced 11'2" arm.

The PC1250-7 can also be configured as a material handler with options such as 55 through 70-foot material handling fronts, clamshells, grapples, magnets and cab risers. Whatever the application, the PC120-7 MH can be a highly efficient loading and unloading tool.

Finally, the PC1250-7 can be purchased as a loading shovel. Featuring the standard length 21'1" track frame, 18'6" boom and 13'5" stick, the PC1250-7 loading shovel is a highly refined performer in truck loading applications where it is necessary for the loading tool to set on the same level as the dump truck.
