Caterpillar 318D L Series 2 hydraulic excavator

The new Caterpillar 318D L Series 2 excavator is said to include powerful hydraulics, a heavy-duty front end and enhanced operator comfort.

Fitted with an economical Tier 2/Stage II compliant engine, the 318D L Series 2 model is also described as easy-to-service and capable of high production with low fuel consumption. With a net power rating of 82kW and operating weights to 17.3tonnes, the new model provides a choice of a boom and two sticks to best fit its application. As well as offering a high level of comfort, the new hydraulic excavator’s cab can also offer excellent visibility.

The 318D L Series 2 consumes an estimated 3% less fuel than its predecessor. Fuel system reliability is further enhanced by dual filtration, including water separation in the primary filter. The engine's economy mode balances performance and fuel economy to provide fuel savings, while maintaining high breakout forces and lift capacities.

A new compact design for the hydraulic system is said to result in more efficient use of power by incorporating shorter hoses and tubes to reduce friction and pressure drop. The 178 Caterpillar-designed hydraulic system employs two pumps in all operating situations, resulting in enhanced productivity and faster implementation speeds. An automatic boom/swing-priority system selects the most efficient mode of operation, based on joystick movement, eliminating the need for operator-selected work/power modes.

To enhance overall productivity in specific applications, a reach boom is available for the 318D L Series 2. Also available are two reach sticks that use added reinforcement for reliable performance. For added versatility, the 318D L Series 2 can use either of two couplers, the CW for severe application and the Center-Lock Pin Grabber. Available hydraulic kits for field installation facilitate adapting work tools to the machine.

The new Caterpillar hydraulic excavator is also equipped with S·O·SSM (Scheduled Oil Sampling) ports and hydraulic test ports, and a connection for the Cat Electronic Technician service tool is easily accessible behind the cab. Most routine service points are accessible from ground level, and a right-side service door allows servicing of the machine's filters. Hydraulic filter changes are extended to 2,000 hours, and the air-cleaner's double-element design is said to provide superior cleaning efficiency.
