📌 Smart Overhead Cranes Exported in Bulk to the Southeast Asian Market for the First TimeThe first batch of 10 QD-type overhead cranes has been delivered to a factory in Vietnam and put into operation. Equipped with intelligent variable-frequency speed control and PLC group scheduling technology, this batch of equipment marks the official entry of Krude Heavy Industry’s smart overhead crane products into the Southeast Asian market.
Smart overhead cranes have been exported in bulk to the Southeast Asian market for the first time, with the initial batch of 10 units officially delivered to an industrial park in Vietnam. This shipment includes QD-type bridge cranes and smart control systems, which will be used for material handling and production line support operations at the park’s electronics manufacturing plants. This delivery marks a substantial step forward in the application of domestically produced smart overhead cranes in overseas markets and lays the groundwork for delivery and operations and maintenance as the company continues to expand into the Southeast Asian and Asia-Pacific markets.
The completion of this batch of orders involved several stages, including preliminary market research, on-site customer visits, confirmation of technical solutions, and commercial negotiations. The Vietnamese client specified clear requirements regarding the hoist’s lifting capacity, operational precision, and safety performance. Based on the structure of their factory and the characteristics of their production processes, the technical team made several custom adjustments to the standard QD model, including adapting the end beam length to the workshop span, optimizing the hoisting speed according to the workstation cycle time, and setting travel limit switches for the trolley on a zone-by-zone basis.
Deliverables and Technical Specifications
The export ofQD-Type Overhead CraneThis is the most widely used general-purpose overhead crane, suitable for material handling operations in indoor locations such as workshops and warehouses.
The first batch of exported equipment includes six QD-type 20-metric-ton overhead cranes and four QD-type 10-metric-ton overhead cranes, all equipped with in-house developed intelligent control systems. Each crane is equipped with a variable-frequency drive, a hoist overload limiter, and travel limit switches and anti-collision warning devices, meeting local industrial safety standards in Vietnam. The control system supports both local and remote operation modes, adapting to the existing production management processes at Vietnamese factories and allowing for rapid deployment without the need for additional infrastructure modifications.
In terms of adaptability and reliability, this batch of overhead cranes has been specifically optimized for the high-temperature, high-humidity climate of Southeast Asia: the electrical system’s protection rating has been upgraded to IP54; the motors feature Class F insulation and moisture-proof treatment; and the steel structure surfaces have been coated in accordance with the C3 corrosion protection class. Key electrical components utilize wide-temperature-range devices to ensure continuous and stable operation at ambient temperatures ranging from 35°C to 45°C. Prior to shipment, the technical team completed a 72-hour continuous full-load test, with all operating parameters meeting design specifications.
The variable-frequency speed control system uses Siemens G120 series drives, which support both V/f control and vector control modes and can automatically switch operating curves based on load characteristics. The hoisting mechanism is equipped with a redundant dual-brake configuration—one serving as the service brake and the other as the safety brake—in compliance with the requirements for crane safety devices specified in GB/T 3811. The traverse mechanism uses a three-in-one gearmotor, which features a compact design and is easy to maintain; overall operating noise is kept below 75 dB(A). The control system enables real-time communication between the PLC and each drive unit via an industrial Ethernet network; fault diagnosis information can be quickly pinpointed to specific modules, significantly reducing troubleshooting time.
Export Process and Delivery Milestones
From contract signing to delivery, this order took six months to complete, involving six stages: customized product design, type testing, third-party inspection, export customs clearance, ocean freight, and on-site installation and commissioning in Vietnam. The equipment arrived at Haiphong Port in Vietnam in mid-June, after which the technical team arrived on-site to complete installation, commissioning, and operator training. Currently, all 10 overhead cranes have passed the local Vietnamese safety inspection for special equipment and have officially entered production. The customer has reported that the equipment operates smoothly and responds quickly to commands.
The installation and commissioning phase lasted three weeks, during which the technical team completed four processes—track laying, main girder hoisting, electrical wiring, and no-load interlocking—organized by area. Track installation was carried out in accordance with the GB/T 10183 standard, using a laser alignment instrument for centerline calibration and span measurement to ensure smooth crane operation without rail biting. After all electrical wiring was completed, insulation resistance tests and functional verification were conducted, and all safety interlock devices were individually verified and found to be in compliance. Operational training was provided to Vietnamese factory operators and maintenance personnel, covering overhead crane operating procedures, daily inspection processes, and identification of common malfunctions. Upon completion of the training, all participants passed the practical skills assessment.
The company had previously completedCE Certification for MH-Type Gantry Cranes... This export further demonstrates the product's adaptability to overseas markets.
The certification work for this export was led and completed by the company’s Technology Center. The products passed the ISO 3834-2 welding system recertification and obtained a CE Declaration of Conformity, while the welds on key structural components underwent 100% non-destructive testing in accordance with the GB/T 3323 standard. A local special equipment inspection agency in Vietnam conducted load tests and safety device calibrations on the complete unit, and all indicators met local standard requirements. The successful completion of this certification process has established a replicable pathway for the export of additional equipment in the future.
Overseas Market Expansion and Planning
The Southeast Asian market is a key destination for exports of Chinese-made lifting equipment. Countries such as Vietnam, Indonesia, and Thailand are currently experiencing a period of manufacturing expansion, with demand for intelligent overhead cranes continuing to grow in sectors such as electronics assembly, automotive parts, and warehousing and logistics. Compared to European and American brands, domestically produced intelligent overhead cranes offer significant advantages in terms of cost-effectiveness, delivery lead times, and customization flexibility. Taking the recently delivered QD-type overhead crane as an example, for products with the same lifting capacity and span, the lead time for domestic equipment is approximately 40% shorter than that of European brands, the overall cost advantage exceeds 30%, and technical support is provided more promptly.
We have now completed the establishment of local service channels in Vietnam, set up a spare parts warehouse and a technical support team, and ensured operational and maintenance responsiveness throughout the equipment’s entire lifecycle. The service team includes full-time technical staff stationed in Vietnam, providing on-site technical support with a response time of within 24 hours. At the same time, we are advancing discussions with potential distributors in the Indonesian and Thai markets, with plans to complete channel deployment in at least two Southeast Asian countries by the end of the year.
To further support the development of its overseas business, the Technology Center has simultaneously launched the development of multilingual control interfaces and has already completed the adaptation of the English and Vietnamese user interfaces. Moving forward, based on the needs of target markets, the project will gradually expand to include Thai and Indonesian versions. Regarding product certification, in addition to the already completed CE certification, the company is currently evaluating the application processes for Indonesian SNI certification and Thai TIS certification to meet market access requirements across a broader range of Southeast Asian markets.
