Caterpillar 315 GC Compatible Attachments
The Caterpillar 315 GC is a mid-size hydraulic excavator in the 15-ton class, built for reliable excavation, trenching, utility work, grading, road repair, and site preparation. Powered by the Cat C3.6 engine delivering 73.3 kW (98 hp) at 2,400 rpm, this machine balances fuel efficiency with solid performance, offering an operating weight of 15,400 kg (34,000 lb) and a maximum digging depth of 5,990 mm (19 ft 8 in) with the long stick configuration.
Attachment fitment for the Caterpillar 315 GC should be checked against the machine's carrier weight, hydraulic flow and pressure, pin dimensions, stick configuration, coupler style, and the material being handled. BHE Attachments can help review these details before quoting or installing an attachment.
Caterpillar 315 GC Attachment Matches
The attachment categories below are organized for the Caterpillar 315 GC carrier class. Final compatibility should be confirmed using the exact machine configuration, hydraulic setup, mounting dimensions, coupler style, and job application.
Hydraulic Breakers for Concrete, Rock & Asphalt
Hydraulic breakers and hammers are a key attachment match for the Caterpillar 315 GC when the job requires concrete breaking, rock breaking, asphalt removal, trenching through hard material, or demolition support.
Montabert breaker models previously identified for review with this carrier class include 501NG and XL1000. Final selection should be based on the carrier's hydraulic flow, operating pressure, breaker weight, bracket setup, and duty cycle.
Digging, Trenching, Grading & Cleanup Buckets
Bucket selection for the Caterpillar 315 GC should match the work being performed. Digging buckets are commonly used for excavation and trenching, while grading or cleanup buckets are better suited for ditching, slope work, backfill shaping, and finish grading.
Bucket fitment should be checked by pin diameter, pin spread, stick width, coupler configuration, width, capacity, tooth style, edge type, and material conditions. The 315 GC offers 2.5 m (8 ft 2 in) and 3.0 m (9 ft 10 in) reach stick options with SAE bucket capacities up to 0.76 m3 (0.99 yd3).
Couplers, Thumbs & Grapples
Couplers, thumbs, and grapples can improve the Caterpillar 315 GC's usefulness for attachment changes, debris handling, brush handling, demolition cleanup, pipe handling, and sorting material on job sites.
These tools should be reviewed for stick geometry, thumb length, coupler type, hydraulic plumbing, bracket style, and the machine's lifting and stability limits. The 315 GC delivers a maximum reach of 8,690 mm (28 ft 6 in) and a swing torque of 35 kN·m (25,815 lbf-ft) for versatile material handling.
Plate Compactors for Trench & Backfill Work
Plate compactors can be reviewed for the Caterpillar 315 GC when the work involves trench compaction, utility installation, backfill compaction, road repair, or site preparation.
Compactor compatibility should be confirmed by attachment weight, hydraulic flow, pressure range, mounting bracket, hose routing, and the compaction area required for the job. The 315 GC's hydraulic system delivers 247 L/min (65 gal/min) implement flow with a maximum equipment pressure of 35,000 kPa (5,075 psi).
Rippers & Specialty Excavator Tools
Rippers and specialty tools may be considered for the Caterpillar 315 GC when the machine is working in compacted soil, frost, hardpan, rocky material, or site preparation conditions where a standard bucket is not the most efficient first tool.
Tool selection should be based on material type, breakout needs, carrier size, mounting setup, and whether the tool will be used before bucket excavation or as part of demolition cleanup. The 315 GC generates 98.67 kN (22,180 lbf) ISO bucket digging force and 59.29 kN (13,330 lbf) ISO stick digging force for tough ground conditions.
Caterpillar 315 GC Jobsite Applications
These application notes help connect the Caterpillar 315 GC to the attachment type most often used for each kind of work.
Concrete & Rock Breaking
Use a properly sized hydraulic breaker or hammer when the Caterpillar 315 GC is assigned to concrete removal, rock breaking, asphalt removal, trench obstruction removal, or demolition prep.
Excavation & Trenching
Use digging, trenching, or rock buckets when the machine is being used for utility installation, drainage work, foundations, roadwork, and general excavation.
Grading & Cleanup
Use grading, cleanup, or ditching buckets when the job requires finish shaping, slope work, ditch cleaning, loose material handling, or surface cleanup.
Material Handling
Use thumbs, grapples, or coupler-supported tools when the Caterpillar 315 GC needs to handle debris, brush, pipe, demolition material, or irregular objects.
Compaction
Use a plate compactor when the machine is supporting trench backfill, utility repair, road repair, or site preparation where controlled compaction is needed.
Hard Ground Preparation
Use a ripper or specialty ground-engagement tool when compacted soil, frost, hardpan, or rocky material needs to be loosened before excavation.
Attachment Fitment Factors
The Caterpillar 315 GC should be matched with attachments using both machine specifications and jobsite requirements. These checks help reduce incorrect fitment, poor performance, and unnecessary attachment wear.
Machine & Mounting Requirements
- Confirm carrier operating weight (15,400 kg / 34,000 lb) and excavator size class.
- Check pin diameter, pin spread, stick width, and coupler configuration.
- Match the attachment bracket to the Caterpillar 315 GC mounting setup.
- Review attachment weight against machine lifting capacity and stability limits.
- For buckets, confirm width, capacity, tooth style, edge type, and application rating.
- Verify stick length (2.5 m or 3.0 m) and track shoe width (500 mm to 770 mm) for ground pressure and reach needs.
Hydraulic & Application Requirements
- Confirm hydraulic flow (247 L/min / 65 gal/min implement flow) and pressure (35,000 kPa / 5,075 psi equipment pressure) for powered attachments.
- Verify auxiliary hydraulic circuit setup, controls, and hose routing.
- Select breaker tools based on material, including moil point, chisel, blunt, or specialty tools.
- Match the attachment to the material being worked: concrete, rock, asphalt, soil, brush, or debris.
- Review duty cycle, production needs, operator use, and jobsite conditions before final selection.
