Model 317 Caterpillar excavator digs to 21 feet with a maximum reach at ground level of 29 feet 7 inches and maximum loading height of 20 feet 7 inches. Operating weight is 40,200 pounds, and it is powered by a 130-horsepower Cat C4.4 diesel.
Also available is the GC version, which does not offer the standard technologies on the Cat 317 that boost operating efficiencies by 45 percent, according to the company. The Cat 317 GC has a 119-horsepower Cat 3.6 diesel, and operating weight of 38,100 pounds.
Three engine operating modes match performance to the job. Smart mode automatically matches engine and hydraulic power to working conditions to improve efficiency; ECO mode minimizes fuel consumption on less demanding applications. The 317 Caterpillar excavator also offers Power mode, which constantly provides maximum power and productivity for the most demanding projects.
The responsive hydraulic system balances the need for power and efficiency to deliver precise digging. A new main valve control eliminates the need for pilot lines, reduces pressure losses, and lowers fuel consumption. Both models come standard with Cat Advansys bucket tips, which offer increased life, excellent retention, and fast changes to maximize uptime on the job, according to the company.
Standard technology on the Cat 317 includes Grade Assist, which automates boom, stick, and bucket movements. Cat Grade with 2D automatically guides depth, slope, and horizontal distance to grade through the touchscreen monitor and can be upgraded to Cat Grade with Advance 2D or Cat Grade with 3D.
Cat Payload technology provides all critical operating data such as payload summaries, fuel usage, and fault codes, which are captured by standard Product Link technology and accessed by fleet managers and office personnel via Vision Link and the Cat App.
Cat Remote Services technologies leverage reported telematics data from the 317 to allow Cat dealers to remotely keep the excavator operating at maximum production and efficiency. Remote Troubleshoot analyzes real-time machine operating data to allow dealer technicians to run diagnostic testing and pinpoint issues without impacting machine productivity. Remote Flash ensures the excavator is operating with the most current version of on-board software, while working around the machine’s production schedule, so it delivers high performance, maximum efficiency, and minimum downtime.
Maintenance intervals are extended on both the 317 and 317 GC to lower maintenance costs by up to 20 percent over the previous series. A new hydraulic oil filter delivers improved filtration and a 50 percent longer, 3,000-hour change interval. System longevity is improved through new anti-drain valves that keep the hydraulic oil clean during filter replacement. Filter life and maintenance intervals are tracked on the in-cab LCD monitor.
All checkpoints, including oil, are accessible from ground-level. A second engine oil dipstick offers service techs the additional convenience of checking and filling the oil on top of the excavator.
Next generation cabs are larger and feature a low-profile design plus large front, rear, and side windows. The 317 GC comes standard with the Cat comfort cab, and the 317 offers the choice between deluxe and premium cab designs.
Standard rearview and right-hand sideview cameras improve visibility of the operating area, and the 317 can be upgraded to 360-degree visibility.
