Reviewed 28 October 2026. Source dating: Official detail published 24 January 2018; body, original photo and parameter sheet reviewed 28 October 2026. No new-release or current-stock claim. Catalogue family and model examples retained; illustration is representative, not an exact model.
What the official reference establishes
Hongshuo’s product detail identifies LEAF CHAIN BL644 and is dated 24 January 2018. The linked ANSI heavy-duty leaf-chain sheet includes the BL644 row with ISO-chain reference LH1244. That row lists 19.05mm pitch, a 4 × 4 plate structure, 3.20mm plate thickness and a 7.94mm pin-diameter entry. These are supplier-catalogue identifiers, not a current production drawing or a vehicle-specific approval.
Define the work before choosing a configuration
The leaf-chain form uses interleaved plates and transverse pins; it must not be confused with a roller chain just because a nominal pitch is similar. Ask for the complete existing chain code, plate stack, pin and end-connection drawings, chain length, equipment identity and proposed application. The common catalogue photograph explains the family form but cannot verify every plate count, tolerance or terminal arrangement on an offered chain.
Keep the supply package explicit
The supplier table also contains minimum and average tensile-strength columns. Those figures are not a working-load limit, an allowable forklift lift capacity or a substitute for the equipment manufacturer’s chain specification. No safe-load value is calculated here. Ask the responsible technical party to confirm the exact assembly, supporting documentation and application match. This page provides no chain replacement, tension adjustment, joining, inspection-limit or lifting procedure.
Questions for the proposed product
Which complete chain specification is being quoted?
State the full series and suffix, construction, pitch, plate or strand arrangement, pin/roller/bore geometry, length, end connections and any attachments. Request the current approved drawing tied to the offer.
What proves the application match?
Provide the installed equipment identity and its chain specification to the responsible technical party. Require written application review. Similar pitch or appearance and catalogue tensile strength do not establish interchangeability or allowable lift load.
What is included and documented?
Confirm quantity, current availability, material/finish, connecting and attachment scope, traceability, required technical documents, delivery and warranty. Website categories do not independently prove certification, stock, authorization or vehicle fitment.
From product research to a comparable request
Prepare a written component requirement preserving the installed equipment identity and full chain specification. Compare the correct chain series, construction, pitch, geometry, length, end connections, attachment pattern, material and documentation. Keep unresolved differences visible for technical review. Existing supplier and purchasing tools remain below; following a link does not itself send an enquiry.
Sources and evidence boundary
The official contact body identifies Jinhua Hongshuo Chain Co., Ltd. at No.1389 Xianyuan Road, Wucheng District, Jinhua, Zhejiang. The company-controlled product bodies, individual original photos and linked parameter sheets were read directly. The product details retain their 24 January 2018 publication dates; a current reachable page is not proof of a new release, current stock or unchanged specifications. Supplier standard-series headings are not independent certification. Generic forklift application wording does not approve every chain for a truck. Confirm the current complete specification, application, contracting entity and documentation. Images explain chain form and are not dimensional, strength, factory or test evidence. No installation, replacement, adjustment, joining or lifting procedures are provided.
