XCMG XESA2B-CL15M
This device is a safety protection component designed for various lifting equipment. It uses a weight sensor to detect the hook position. When the hook rises to the preset height, it automatically cuts off the hoisting power circuit to prevent collision between the hook and the top of the boom (anti-two block/anti-overwinding), effectively protecting equipment and personnel safety. Built with industrial-grade protection, it withstands harsh outdoor working conditions of construction machinery and is a mandatory core component required by lifting machinery safety regulations.

How To Choose anti two block system crane Supplier
If you are searching for China Crane Anti-Two-Block System Manufacturer, Factory & Suppliers, start by confirming whether the supplier can match your crane type, installation needs, signal requirements, and project documentation process.
A good RFQ should include application details, target quantity, required specifications, sample needs, inspection expectations, and delivery destination. This helps the supplier respond with clearer product recommendations and more useful quotation information.
Begin with the working environment and crane configuration. Share the crane model, load conditions, mounting position, required alarm or limit function, and any interface details. This allows the supplier to check whether the anti-two-block system is suitable before discussing price.
For a new product line, compare related products side by side. Review dimensions, installation method, cable or wireless options, enclosure details, operating conditions, labeling, packaging, and available customization. If you have drawings, photos, or a reference sample, include them in the first inquiry.
Quality review should include incoming material checks, assembly inspection, function testing, appearance review, packing verification, and basic traceability records where applicable. Ask what documents can be provided with samples or bulk orders, such as specifications, test records, user instructions, or inspection summaries.
Before confirming an order, clarify sample confirmation, lead time, warranty terms, spare parts support, after-sales communication, and how nonconforming issues are handled. Clear RFQ preparation reduces repeated communication and helps your team compare supplier options more fairly.
| Criteria | Importance | Description | Example Options |
|---|---|---|---|
| Signal interface | High | Must match crane controller input. | Relay, analog, or digital output |
| Mounting design | High | Affects installation and repeatability. | Boom tip bracket layout |
| Inspection records | High | Supports quality review and traceability. | Function test checklist |
| Customization scope | Medium | Useful for new product lines. | Cable length or connector type |
| Documentation package | Medium | Improves RFQ and sample approval. | Drawing, wiring, test report |
