Start with the work you need done
Purchase an attachment
Name the task and material, then the carrier make/model and mounting arrangement. Obtain the offered attachment’s maker, model, current datasheet and included bracket/hoses/tooling before comparing prices.
Breaker selection brief →Repair an existing unit
Supply make, model/serial, symptoms, service history and existing modifications. Agree inspection authorization, proposed replacement parts, estimate approval and the returned test record.
Plan the repair record ↓Buy replacement parts
Keep the original part reference, dimensions and equipment identity together. Ask whether the proposed part is original, independently supplied or manufactured by Gonggong, and who supports fit and function.
The menu separates hydraulic breakers, high-frequency breakers, pulverizers, shears, compactors, grabs and quick couplers. [1] Task and hydraulic interfaces differ; a catalogue category alone is not carrier approval.
Clarify the seller, maker and service provider
The official introduction identifies 杭州共工机械有限公司 and describes whole-attachment sales, service/repair and parts manufacturing. Its footer gives an Yiqiao steel-market address in Xiaoshan, Hangzhou. [1] The homepage presents store, warehouse, dispatch and field-repair panels. [3] These support a supplier/service role, not proof of a finished-breaker production line.
- Attachment manufacturer
- Request the legal maker and exact model on the quotation and identification plate.
- Installation responsibility
- Identify who confirms mounting and hydraulic matching and who documents carrier alterations.
- Parts responsibility
- Specify provenance, replacement reference, interface confirmation and applicable support terms.
- Repair responsibility
- Name the inspecting/repairing entity, authorized scope, testing and dispute/return procedure.
The introduction mentions support from “泰猛” without defining a corporate or authorization relationship. It is not presented here as ownership or a licence. Ask for the actual relationship if the offered product relies on it.
A repair should return more than a working photograph
Gonggong’s August 2019 inspection/repair article discusses fasteners, lubrication, contamination and symptom categories. [4] It is not tied to a named model. We do not apply its intervals or adjustment instructions universally to other breakers.
- 1
Record the received condition
Agree identity, visible damage, attachments supplied, symptoms and an inspection scope. Preserve the buyer’s complaint and previous modifications before dismantling changes the evidence.
- 2
Approve the proposed work
Request findings, parts references/provenance, labour, testing, transport and exclusions. Set an approval point for additional work rather than treating an initial estimate as unlimited authorization.
- 3
Document the returned unit
Obtain the replaced-part list and defined test results, operating conditions and remaining limitations. State the repaired serial, repair warranty and required installation/maintenance documents.
HSE’s hydraulic safety alert calls for replacement fittings compatible with the original equipment specification and appropriate pressure-test precautions. [5] Use qualified personnel and the actual equipment instructions; this enquiry guide supplies no pressure-setting or dismantling procedure.
Turn the advertised support into written terms
The homepage advertises 24-hour customer support and lifetime maintenance. [3] It does not establish free lifetime repairs, response times in every country or unlimited warranty. Agree service hours/region, remote versus site work, labour/parts/transport charges and escalation contacts for your quotation.
Historic site cases and operating videos illustrate tasks. They do not establish measured output, current stock or approved underwater/tunnel use for the proposed attachment. Special duty requires exact equipment and installation documentation. No independent factory audit or authenticated model conformity file is established in this review.
Keep the enquiry on the chosen route
