The 300 family sleek styling on wheels. Both the cab and body have smooth, rounded contours with blended-in roading lighting for a modern look.
Conveniently located grab irons and large steps mounted on the undercarriage allow easy access to the cab.
The cab is resiliently mounted. Sound suppression panels considerably reduce outside noise levels.
The suspension seat adjusts to the operator's weight and offers excellent lumbar support. There are height-adjustable armrests and numerous seat adjustments.
Wide windows help ensure excellent visibility in all directions.
Strategically located vents circulate forced air, heat or defrost air for maximum comfort.
The control panel switches are conveniently located.
The closed center, variable flow, load sensing hydraulic system is state-of-the-art.
Dedicated swing pump - A separate dedicated variable displacement piston pump and fixed displacement piston motor power the swing mechanism.
Efficient and expandable hydraulic system - Up to four optional hydraulic valves can be added to the main valve stack for additional hydraulic functions.
The right side console contains switches for the power mode selector, automatic engine control, lights, windshield wiper and washer, and travel speed selector.
A microprocessor monitors and controls M312 parameters and functions.
The electronic control system monitors and controls the following functions: Three power mode settings - The operator can choose the optimum power settings for both engine and hydraulics, without any loss of hydraulic forces.
Automatic engine speed control - When activated, this device reduces engine speed to a minimum during periods of inactivity which reduces noise and saves fuel. A button on the right joystick immediately sets the idle down manually.
Electronic underspeed control - Constant electronic monitoring assures that the pump output is always matched to diesel engine power. As a result, a nearly constant diesel engine speed is maintained.
The maximum power is reduced when the engine temperature is too high or the hydraulic temperature is too low or too high.
System parameters and failure identification codes can be read by using a diagnostic tool.
Travel speed lock (option) - Holds the travel pedal in the maximum position to ease the strain on the operator. Pedal is released when brake is activated.
Conservative 84.3 kW (113HP) rating, high power to displacement ratio of 21.3 kW/ liter and low rpm operation ensure long life and exceptional reliability.
The 3054TA is an emission controlled engine. Featuring very low emission levels, it complies with the 97/68/EC Non-Road Mobile Machinery Engine Emission Directive and the US EPA Non-Road Regulation.
Four-stroke-cycle design uses long power strokes for more complete fuel combustion and efficiency. Accurate fuel metering results in low fuel consumption.
Long-life design includes large bearing surfaces, alloy steel valves, lightweight cam roller followers and easily replaceable crankshaft seals.
The engine is designed for high torque rise at medium rpm. This is suited for excavator applications.
The engine is longitudinally mounted on the right to make it easier to service the oil filter, oil filler, oil drain valve, fuel filter, V-belt tightener and dipstick, which are all accessible from ground level.
A strong and long-life welded frame structure built with large sections and thinner plates for maximum rigidity.
Heavy duty axles. The front axle offers the best axle oscillation and steering in the industry for optimized flexibility and mobility.
Recommended for maximum operation stability when digging and lifting.
A useful addition for leveling and backfilling or clean-up work, also used to improve machine stability when digging or lifting.
One-piece boom 4.80 meters (15'9") - For all standard applications. It is built with large sections and thinner plates for maximum weight reduction and durability and has been Finite Element Method analyzed. Recommended for hammer applications.
Hydraulically adjustable boom (VA) max. 5.05 meters (16'7") - For improved visibility and machine roading balance. Indicated when working in tight quarters. It is built with large sections and thinner plates for maximum weight reduction and durability and has been Finite Element Method analyzed.
VA offset boom 5.05 meters (16'7") - In this configuration, the VA boom can be adjusted horizontally as well.
Three stick lengths are available for maximum flexibility.
With FEA, a more stable and reliable base frame and upper frame structure could be designed. For maximum strength and best range, all linkage parts (boom, sticks) have been analyzed to achieve an optimal balance of weight reduction versus fatigue strength. This also includes the offset boom.
For industrial or agricultural applications choose the best matching boom and the 2.8m (9'2") industrial droop nose stick. With this stick, a free swinging work tool can be used.
Efficient and expandable hydraulic system - The flow distances between hydraulic components are minimized.
Caterpillar XT hoses and couplings meet the critical flexibility and strength demands of wheel excavator applications.
Factory installed hammer hydraulic lines are available. These lines allow single acting function for dedicated proportional hammer foot control for maximum protection and durability.
High pressure hydraulic lines (Optional)
Medium pressure hydraulic lines (optional)
For some buckets, there is also interchangeability with 315B track type excavator buckets.
A variety of work tools are available from your Cat dealer for the M312 wheel excavator.
The following tips are available for the buckets for the M312: Long tips, Short tips, Penetration tips, and Long heavy duty tips.
