Coyote Loader Sales Inc.
Coyote mini-excavators are manufactured by Nagano Industries in Japan. Fuel economy is achieved through the use of fuel-efficient, low-horsepower engines. The hydraulic system power, supplied by the high-efficiency pumps, results in higher breakout force.
Komatsu America Corp.
Komatsu's new excavator engines are designed to deliver optimum performance under the toughest conditions, while meeting the latest environmental regulations. Most models are equipped with engine working modes. Each engine mode is designed to match engine speed, pump flow and system pressure with the current application, enabling the operator to increase production and lifting power or reduce fuel consumption.
Case Construction Equipment
All current Case CX Series Excavator engines are fully electronically controlled, which means they operate at peak efficiency for the function being performed. The units feature pressure-compensated hydraulics, which match hydraulic horsepower to hydraulic function. This provides very efficient operation. In general, many improvements to hydraulic systems increase both fuel economy and performance.
Kubota Tractor Corp.
Kubota engineers select an engine with just enough horsepower to run the hydraulic system, plus a little extra for heavy-duty applications on hot days or when the machines are used at altitude. Variable-displacement pump systems can change the oil flow for varying load conditions, further reducing fuel consumption. Other fuel-saving features include a load sensing system and auto idling system.
JCB is constantly refining its excavator products to get the most powerful and efficient machines available, while ensuring compliance with the legislation demands for ever-lower emissions and noise levels in the construction industry. The combination of simple-to-use electronics and easy maintenance ensures that any JCB excavator can continue to work at its highest level of performance year in and year out.
To deliver increased power and performance without sacrificing fuel economy, Mustang excavators' hydraulic system components are properly matched and sized. Calculating the right size, pressure and flow requirements are critical depending on the unit's physical size. To do this you must know the physical power requirements and the available space for an engine for a given unit and specify components accordingly. That is the key to fuel economy.
Caterpillar engines with ACERT Technology precisely control fuel and air delivery and shape the combustion cycle to optimize fuel combustion for reduced emissions and optimum work output. The ADEM A4 engine controller tracks engine and machine conditions to keep the engine operating at peak efficiency. In addition, automatic engine speed control — a two-stage, one-touch control system — helps to maximize fuel efficiency by reducing engine speed when the machine controls are not being manipulated.
Ingersoll Rand's 7.5-metric-ton ZX-75 and 12.5-metric-ton ZX-125 compact excavators provide optimum performance for building, landscaping, utility installation, general construction and repair work. The ZX-75 has a 16,538-lb. operating weight and a 72-hp, four-cylinder, turbocharged diesel engine. The ZX-125 has a 27,563-lb. operating weight and a 94-hp, four-cylinder, turbocharged diesel engine. Both feature zero tailswing to safely operate in tight jobsite conditions.
