Causes of bucket failure and repair methods
Reasons for bucket failure: 1.The right PPC valve stick oil path is blocked. 2. The spool of the bucket control valve is worn. 3. The bucket compensation.
Causes of bucket failure and repair methods
Reasons for bucket failure: 1.The right PPC valve stick oil path is blocked. 2. The spool of the bucket control valve is worn. 3. The bucket compensation valve is damaged. 4. The spool of the suction valve of the Carter excavator bucket is stuck or the spool is worn, or the seal of the suction valve of the bucket is damaged. 5.The backup valve of the LS shuttle valve fails. 6.The oil passage of the bucket is blocked and the oil supply is not smooth. Repair method of failure: 1.The bucket control lever is in the middle position, the PPC output pressure is 0; the bucket is digging or unloading, the PPC output pressure is 2.9mpa. 2. Check that the spool in the control valve of the excavator bucket is not worn, the spool of the suction valve of the bucket is not stuck, and the seal is not damaged. 3.Check that the LS shuttle valve of the backup valve control valve is working normally. 4. Turn off the excavator engine, and operate the excavating action of the bucket when the engine is at a
Buyers usually compare two things: whether the machine will hold its rated output on a hot day with damp aggregates, and whether anyone will answer the phone in year three. HAMAC designs for both.

True-stage matching
Crusher chamber profile, eccentric throw and screen deck are matched to each other, so no single stage becomes the bottleneck of the whole Causes of bucket failure and repair methods.
Dust and noise control
Enclosed screen decks, water spray bars and optional bag filters keep the plant within site emission limits.
Spare capacity designed in
Conveyors and screens are sized roughly 15% above nominal so short-term peak demand does not stall the line.

| Crushing stages | Two-stage, three-stage or four-stage closed circuit |
From Enquiry to Commissioning
Six defined stages, each with named deliverables, so nothing is left to interpretation.
Requirement study
We start with your mix design, hourly output target, aggregate size, jobsite power supply and site layout — not with a catalogue page.
Scheme design
Our engineering team issues a layout drawing, foundation loads, power requirement and an equipment list matched to the target output.
Quotation & contract
A fixed specification quotation with clear technical annexes protects both sides; no vague "standard configuration" wording.
Production & inspection
Weekly production photos, welding and pressure test records, plus third-party inspection if your project requires it.
Delivery & installation
Container or break-bulk shipment, then on-site supervision of assembly, alignment, calibration and dry-run.
After-sales
Remote diagnostics by video call, spare parts dispatch within 48 hours for stocked items, and periodic return visits.
Frequently Asked Questions about Causes of bucket failure and repair methods
Is a mobile plant worth the extra cost?
If your plant moves more than twice a year, or if foundation work is expensive at your site, the crawler or wheeled version usually pays for itself inside two seasons.
What output can I realistically expect?
Published figures assume continuous, well-graded feed. In the field, expect 80-90% of nominal throughput; HAMAC quotes conservative rather than theoretical numbers.
How much maintenance does the plant need daily?
Roughly 30 minutes: check lubrication pressures, belt tracking, screen mesh tension and hydraulic oil temperature. Weekly items add oil sampling and bolt re-torquing.
How do I choose between a jaw and an impact primary crusher?
A jaw handles abrasive and high-strength rock up to roughly 320 MPa and gives a low wear cost per tonne, while an impact crusher produces a far better particle shape for concrete aggregate but wears faster on hard or abrasive stone.
Can the plant be upgraded later?
Yes. Conveyors, screen decks and even the tertiary crusher can be added later because we keep the layout modular and reserve structural capacity for it.
