Description

Fuel Economy – Automatic Engine Control, Fuel Delivery and Manual Low Idle

Two-level control with one-touch command maximizes fuel efficiency and reduces sound levels during no-load or lighter-load applications. Fuel delivery is managed by the ADEM A4 Engine Controller for the best performance per litre of fuel used. Flexible fuel mapping allows the engine to respond quickly to varying application needs. Electronic controls govern the fuel injection system. Multiple injection fuel delivery involves a high level of precision. Consequently, the carefully shaped combustion cycle lowers 4the combustion chamber temperatures, generates fewer emissions and thus optimizes fuel consumption. For you, this means more work output for the same amount of fuel consumed.

Outstanding Performance – With two per cent more hydraulic pressure for additional lift and breakout forces, the 312D’s hydraulic system is designed for high efficiency and performance. The new compact design utilizes shorter tubes and lines, reducing friction and pressure drops, resulting in more efficient use of power.

• – Hydraulic snubbers at the rod end of the boom cylinders and both ends of the stick cylinder cushion shock, reduce sound and increase cylinder life.
• – Flow is reduced to a minimum when controls are in neutral to reduce fuel consumption and extend component life.
• – Electronic under speed control electronically adjusts pump output so that it doesn’t exceed engine power, preventing the need to reserve engine power to avoid engine stalls.
• – The hydraulic cross sensing system uses two more hydraulic pumps up to 100 per cent of engine power under all operating conditions, improving productivity with faster implement speeds and quicker, stronger pivot turns.

Boom and Stick Regeneration Circuit – The boom and stick regeneration circuit save energy during boom-down and stick-in operation, increasing efficiency and lowering operating costs. What is more, regeneration during boom down operations is electronically assisted. This system increases hydraulic flow regeneration, which leads to faster operations and reduced pressure loss and hence improved fuel efficiency.

Easy Operation – Work mode and power mode switches are eliminated making full power mode available at all times. Operators do not need to learn different modes, an automatic boom and swing priority function automatically select the best mode based on joystick movement.

Two Pump Flow – The two pump combined option, available with the single action control circuit option, allows for increased productivity in single-action applications.
