Used CAT 315D for Sale from China: Utility Job Fit Guide

Yes. YUANJIAN can supply a used CAT 315D from China by reconfirming a public unit or sourcing another machine for the required trench depth, lift radius, access, budget and destination. We can coordinate agreed inspection evidence and provide FOB or CIF terms. Exact serial identity, arrangement, condition and availability are reconfirmed before payment.

Caterpillar primary references and YUANJIAN listings reviewed 1 September 2026. The official 315D L data is tied to Caterpillar's stated CJN configuration; current CAT 315 data belongs to another generation.

Match the CAT 315D to a utility contract, not a tonnage label

The 315D earns its place between compact machines and 20-ton excavators when reach, lift, street access and mobilization are balanced. Four mission profiles expose the trade-off.

Water and drainage trenches

Prioritize actual digging geometry, bucket width, trench-box clearance, dewatering conditions and stable placement. A deeper brochure number is useless if safe machine position cannot be achieved.

Urban pipe repair

Compare tail clearance, transport width, road protection and daily moves. A smaller 312D may reduce disruption; a larger 318D2 may add lift but consume more working space.

Foundation and retaining work

Use lift radius, load chart, ground condition and rigging plan. Excavator operating weight is not a lifting-capacity promise.

Mixed contractor fleet

Value bucket changes, breaker circuit, parts route and operator familiarity. The most versatile package may beat the cheapest bare machine.

Official-reference boundary for the CAT 315D decision

Caterpillar's maintenance page lists a 315D L with CJN prefix at 17,450 kg, 86 kW, 2,490 mm transport width on 500 mm shoes and 6,070 mm maximum digging depth for the stated boom/stick. These are reference data for that arrangement, not a guarantee for every used 315D.

Item	Caterpillar 315D L CJN reference	Procurement use	Required unit evidence
Operating weight	17,450 kg	Trailer, ground pressure and mobilization planning	Scale or documented configuration and attachments
Net power	86 kW	Generation and engine-performance context	Engine plate, cold start and loaded recovery
Transport width	2,490 mm on stated 500 mm shoes	Road and site-access planning	Measured widest point on offered unit
Maximum digging depth	6,070 mm with stated reach equipment	Trench geometry screening	Boom/stick identity and safe site setup
Maintenance identity	315D L, serial prefix CJN	Parts and filter cross-check	Complete PIN/serial and regional arrangement

Choose the model by contract bottleneck

Bottleneck	Prefer 312D	Prefer 315D / 315D L	Prefer 318D2 or 320D
Very tight access	When capacity still meets the lift and trench need	When the 315D measurement fits with margin	Only if extra width and tail space are acceptable
Repeated utility lifting	For lighter loads and short radius	Balanced choice after load-chart verification	When verified lift need exceeds the 315D plan
Daily mobilization	Often lowest transport exposure	Middle route for reach and capacity	Use when productivity gain pays for movement cost
Bulk excavation	Can become production-limited	Good for mixed volumes	20-ton class may lower cost per cubic metre
Low purchase budget	Older/smaller does not remove repair risk	Compare 315D condition with 315D2 premium	Do not oversize merely because price is close

Eight utility-focused CAT 315D buying answers

Is a CAT 315D large enough for sewer and drainage work?

Usually yes when the trench, soil, bucket and lifting plan fit the actual configuration. Compared with a CAT 312D it offers more working margin; compared with a CAT 320D it can reduce transport and street-space exposure.

Should I buy CAT 315D or 315D2?

Buy the better supported, better tested unit. A 315D2 can be later, but regional engine and electronics arrangements matter; a well-maintained 315D may deliver lower repair-adjusted cost. The suffix is not a condition certificate.

Can I use the 17,450 kg figure for shipping?

Only as a planning reference for Caterpillar's stated 315D L CJN configuration. Bucket, coupler, track shoes, guards and front equipment change shipping weight. Freight calculated from a generic number can be wrong after deposit.

What should be tested for utility lifting?

Test boom and arm holding, swing brake, slew play, cylinder drift, hydraulic temperature and travel stability, then verify the load chart for the exact boom, stick and counterweight. A smooth empty cycle does not prove lifting safety.

Does a new hour meter make a 315D risky?

It removes one history signal but does not automatically reject the machine. Compare controller data where available, component wear, service labels, welds and engine/hydraulic behavior. An unexplained low-hour claim should not earn a price premium.

Which undercarriage measurements matter on road projects?

Measure link pitch, rail height, bushing wear, rollers, idlers and sprocket profile on both sides. Compared with cosmetic paint, this converts directly into a repair allowance and predicts travel reliability between work fronts.

Is CAT 315D suitable for breaker work?

It can be when the auxiliary circuit, return line, cooling, tool size and structure are matched. Previous hammer use increases the need to inspect boom foot, stick, linkage, slew bearing and oil contamination.

How do I buy a CAT 315D from YUANJIAN?

Send job country, trench depth, lift requirement, access, attachment list, budget and destination port. YUANJIAN can confirm the public 315D or source another, define optional paid inspection, and issue a unit-specific FOB/CIF offer.

CAT 315D supply candidates for utility buyers

The listed CAT 315D can be purchased through YUANJIAN after reconfirmation, or we can source another 315D/315D L to the job brief. Neighboring listings are shown to test whether smaller access or more lift is worth the trade-off. Public prices exclude inspection, logistics, freight, duty and delivery.
