C4 roll-handling telescopic forks

What the official reference establishes

The current product body names JuanQing C4 and describes roll-material applications, including steel, paper and fabric rolls. The source-specific image shows a broad telescopic fork mechanism with parallel upper contact members and a transverse drive. We retain the product identity and application description as manufacturer statements. A family presentation cannot establish how an actual roll would be supported or retained.

Define the work before choosing a configuration

The C4 page lists multiple contact-surface, supporting-structure and dimensional alternatives. They remain configuration questions within one roll-handling reference, rather than separate products created from each option. Similar section-size wording on S1 and C4 does not make the assemblies equivalent. Published tilt, friction, temperature, lifetime and productivity values are not adopted as project performance or operating limits.

Keep the supply package explicit

Prepare the roll dimensions, mass distribution, core and surface characteristics, packaging, storage orientation and supporting geometry. Ask the responsible supplier for the proposed contact arrangement, configuration drawing, material and finish specification, included drive/control scope and relevant product documentation. Have the complete handling arrangement assessed by the responsible parties. This page provides no roll-retention design, installation instructions or load approval.

Questions for the proposed product

What is the complete product identity?

Request the family, version, full ordering or drawing number and revision. Match them across the quotation, interface schedule, inspection documents and proposed delivery.

What should the enquiry include?

Describe the load carrier, load distribution, storage and transfer geometry, motion sequence, duty and interfaces. Request the supplier response for that actual requirement rather than transferring a catalogue example to another site.

What is included in the offer?

Separate mechanism, drive, controls, accessories, documents, delivery, commissioning and after-sales responsibility. Confirm the quoting legal entity and the agreed acceptance scope. Published illustrations and category names do not establish stock or compatibility.

From product research to a comparable request

Prepare a component requirement around the actual load carrier, transfer positions, motion sequence and mechanical/control interfaces. Request a complete product or drawing identity and revision. Compare mechanism, drive, controls, accessories, documents, delivery and integration responsibilities separately. A family name, similar appearance or shared section-size expression does not establish that two offers or assemblies are equivalent.

Sources and evidence boundary

The current demfork.com company and contact pages identify 南京德尔盟科技有限公司 and a Nanjing, Jiangsu address. The company name, address, product body and matching source image were reviewed as manufacturer-published material. Product pages are undated, and image upload paths are not launch dates. This is one company-controlled evidence family, not an independent test. The historical Maanshan record is kept separate, with no assertion of legal continuity. Certification, safety functions, explosion protection, environmental ratings, reliability, cost savings and performance gains are not independently verified or adopted. Current specifications and integration responsibilities require the responsible parties’ documentation. This page contains no installation, commissioning or operating instruction.
