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 in crane Supplier
China Crane Anti-Two-Block System Manufacturer, Factory & Suppliers should be evaluated by application fit, technical compatibility, installation requirements, sample confirmation process, and supplier response quality.
Before asking for price, prepare crane type, lifting condition, voltage or signal requirements if applicable, expected order quantity, destination market, and any inspection or documentation needs. This helps suppliers reply with a more useful quotation instead of a general product list.
Start your sourcing work by defining where the anti-two-block system will be used. Share the crane type, working environment, lifting height range, and whether the product is for new equipment, replacement, or maintenance stock.
Compare related products carefully. Some buyers may also need limit switches, crane warning devices, load monitoring accessories, or other crane safety components. Ask the supplier to explain which option fits your application instead of choosing only by product name.
For sample confirmation, prepare technical questions in advance. Confirm installation method, wiring or mounting details if relevant, package contents, labeling needs, and whether instructions or basic documentation can be provided for your approval process.
When reviewing quotations, look beyond unit price. Check lead time, packing method, export carton details, inspection points, communication speed, and after-sales support for installation or usage questions. These details help your purchasing team reduce clarification rounds before placing an export order.
| Criteria | Importance | Description | Example Options |
|---|---|---|---|
| Crane compatibility | High | Matches crane structure and controls | Mobile, tower, or crawler crane |
| Installation method | High | Affects mounting and wiring work | Boom tip switch with cable |
| Signal output | Medium | Must suit alarm or control circuit | Normally open or closed contact |
| Sample confirmation | Medium | Checks fit before order review | Confirm cable and bracket details |
| After-sales support | High | Helps resolve use and maintenance issues | Wiring guide and troubleshooting notes |

These buyer-style notes reflect common sourcing situations such as reviewing export order needs, organizing sample questions, confirming application details, and shortlisting related crane safety products.
I used the page to refine my sourcing notes for an anti two block system in crane applications before contacting China suppliers.
The tag page helped me separate load hook protection questions from general crane controls when comparing anti two block system in crane options.
I found it helpful for writing a focused RFQ that described boom limit concerns and anti two block system in crane requirements clearly.
This gave me a cleaner checklist for asking about compatibility, signal type, and installation context for an anti two block system in crane use.
Frequently Asked Questions
How should our purchasing team compare an anti two block system in crane with related crane safety devices for an export RFQ?
Compare it by function, installation point, signal output, crane type compatibility, and maintenance needs. An anti-two-block system focuses on preventing hook block contact with the boom tip, while other devices may monitor load, angle, or travel limits.
What sample details should we confirm with a China Crane Anti-Two-Block System Manufacturer, Factory & Suppliers before bulk discussion?
Confirm the sample’s switch type, cable length, weight assembly, connector style, power requirements, alarm interface, and mounting method. Share crane model, boom structure, hook block arrangement, and expected operating environment for accurate sample matching.
Which technical parameters are important when preparing an RFQ for crane anti-two-block systems?
Include rated voltage, output signal type, enclosure material, protection level requirement, operating temperature range, cable specification, mounting bracket needs, and alarm connection method. Clear parameters help suppliers assess compatibility with your crane electrical control system.
What quality checks are relevant for an export order of anti two block system in crane components?
Ask about incoming material checks, switch function testing, cable continuity inspection, enclosure sealing review, assembly verification, and final functional testing. These checks help purchasing teams evaluate consistency without relying on unsupported claims.
What after-sales questions should be included when shortlisting China crane anti-two-block system suppliers?
Ask how installation guidance is provided, what troubleshooting information is available, which spare parts are replaceable, and how wiring or adjustment questions are handled. Also confirm documentation format for your maintenance and export order records.
How do we confirm whether the anti-two-block system fits our specific crane application?
Provide crane type, boom length, reeving arrangement, hook block travel path, control cabinet interface, and operating environment. The supplier can then advise whether the system layout, switch position, and alarm output suit the application.
