Key features

Grab bridge cranes are composed of main parts such as bridge, grab hoisting trolley, crane operating mechanism.

Bridge: This metal structure consists of main girder and end girder. The main girder adopts box structure composed of U-channel and I-beam group.

The electric hoist is mainly divided into two categories: wire rope hoist and hand-pulled hoist, and the former is more widely used.

Crane running mechanism: drives the whole crane to move back and forth along the runway beam. The running mechanism adopts separate drive mode, which is completed by conical rotor with brake motor.

Electrical control system: It is the unit that provides electricity for the function of the crane. The electrical system design should consider some matters such as reliability, durability and safety.

AI-Powered supplier vetting

SummaryThe supplier demonstrates broad customization, 3D design, ODM/OEM, SDK, and recent product-development capabilities. Production-related evidence includes CNC machining, robotic welding, laser cutting, inventory capacity, raw-material traceability, 100% finished-product inspection, and 25 quality inspectors. Service-management procedures for supplier assessment, corrective and preventive actions, complaints, and quality assurance are documented and followed. However, the supplier has no valid manufacturing-capacity contract with affiliated subcontractors, no overseas warehouse, showroom, agent, or branch, and no reported offline trade-show participation. Financial records provided for 2024–2025 and cash-flow information for 2023 show zero values across the stated metrics, which does not support financial credibility. No certification holdings or customer-case evidence is provided.

Supplier typeThe supplier presents itself as a manufacturing and design-service provider with CNC machining, robotic welding, laser cutting, customization, ODM, OEM, and SDK capabilities. It has inventory capacity but no overseas warehouse, showroom, agent, or branch, and offers quotations under FOB, CIF, CFR, and EXW terms.

After-Sales capabilityThe supplier has documented and followed procedures for customer complaints, corrective and preventive actions, supplier-service assessment, and quality assurance. However, it has no overseas service agents or branches, no overseas showroom or warehouse, and reports zero countries with overseas services, limiting demonstrated international after-sales coverage.

Financial creditThe provided financial information reports zero operating revenue, operating cost, gross profit, operating profit, cash receipts, cash inflows, cash outflows, gross margin, and current ratio for the stated periods. These figures do not support financial credibility, although the slices do not explain whether the entries reflect actual performance or incomplete reporting.

R&D capabilityThe supplier provides 3D software design, ODM, OEM for known brands, and an available SDK, and reports new products during the past year. ERP integration and related digital systems further support structured operational management.

Production capacityProduction evidence includes CNC machining, robotic welding, laser cutting, raw-material traceability, 100% finished-product inspection, 25 quality inspectors, inventory capacity, and lead times within 15 workdays in both peak and off-season periods. A stated weakness is the absence of a valid manufacturing-capacity contract with affiliated subcontractors.

Customization capabilityThe supplier explicitly supports customization from samples and designs, flexible and minor customization, full customization, 3D software design, ODM, and OEM services. This indicates a broad customization offering across design and manufacturing requirements.

Product Q&A

Q:What is the main application of LDZ type overhead crane?

LDZ type overhead crane is mainly used for loading, unloading, handling and stacking of bulk materials. It is suitable for handling loose materials such as coal, ore, grain, sand and gravel.

Q:What type of grab is standard for LDZ bridge crane?

Usually standard double-flap grab (suitable for materials such as coal, sand and gravel). Multi-flap grab (suitable for wood chips, scrap steel, etc.) or shell grab (suitable for light materials such as grain) can be optional. Grab capacity needs to be matched according to material density and lifting weight.

Q:What are the special requirements for tracks of LDZ crane?

Track model usually needs to be QU80.The track installation accuracy requirements are higher horizontal error 3mm/m.It is recommended to configure a track cleaning device.

Q:What are the special requirements for the control system of grab crane?

It must be equipped with dual motor independent control (lifting + opening and closing); frequency conversion control is recommended to achieve smooth opening and closing of the grab; weight detection and anti-sway functions need to be set.
