Detailed Description & Applications

Overview

The 315 series from Caterpillar is engineered as a medium-class, multi-purpose machine that balances durability, efficiency and operator comfort. This used unit features the CAT C4.4 engine and delivers dependable performance across earthmoving, trenching and loading tasks. Built-in automation improves fuel economy and reduces operator workload, making the machine a practical choice for contractors seeking predictable costs and steady productivity.

Key Features

Engine and Fuel Efficiency

The CAT C4.4 diesel powerplant provides 91 kW of rated power, delivering effective digging and lifting capabilities while maintaining fuel efficiency. The factory-installed automatic engine speed control moderates rpm under varying loads, which reduces fuel consumption during idle and light-load cycles without compromising response under heavy demand.

Hydraulics and Controls

An advanced hydraulic system provides smooth, proportional control for boom, arm and bucket functions. Automatic boom and bucket control simplify repetitive tasks and support consistent cycle times. Optional automatic grade control is available for jobs that require precise depth and slope control, improving accuracy for site prep and utility work.

Undercarriage and Mobility

The heavy-duty undercarriage is designed for stability and long wear life. With a 500 mm track width and robust travel motors, the machine offers secure traction on uneven ground and reliable transport between work zones. Transport dimensions (8.52 m length, 2.49 m width, 2.93 m height) make it practical to move on standard low-bed trailers when needed.

Operator Comfort and Safety

The cab on the 315 provides a spacious, ergonomically arranged environment. Controls are logically placed to reduce operator fatigue; visibility is optimized for safe operation on congested jobsites. Routine access points for maintenance are designed to minimize downtime and support effective inspection intervals.

Typical Applications

• General construction: foundation excavation, backfilling and site preparation.

• Utility and civil works: trenching for pipelines, conduit and drainage systems.

• Road and infrastructure: subgrade preparation, ditching and culvert installation.

• Material handling: loading trucks, stockpile management and light demolition with appropriate attachments.

Benefits for Buyers

1. Lower operating costs driven by automatic engine and implement controls that improve fuel use.

2. Proven Caterpillar componentry (engine, hydraulics, undercarriage) that supports long service intervals and parts availability.

3. Versatility through a broad range of compatible attachments—buckets, hammers, thumbs and couplers—so a single machine can support multiple tasks.

4. Rapid availability and scalable supply: delivery from Shanghai in 15–20 days and a high monthly supply capacity.

Inspection & Purchase Considerations

When evaluating a used unit, confirm maintenance records for scheduled services, inspect the undercarriage and boom for wear or repair history, and verify hydraulic performance under load. This machine has 2,100 hours of operation; buyers should prioritize thorough inspection of seals, hoses and wear points, and consider a pre-purchase consultation with a certified Caterpillar technician when possible.

Logistics & Support

This Used CAT 315 Excavator is stocked in Shanghai with an estimated delivery time of 15–20 days. Supply capacity is listed at 10,000 units per month for the broader inventory offering. Spare parts and service support for CAT units are widely available, which helps maintain uptime in field operations.
