en.Wedoany.com Reported - China's Zoomlion Intelligent Access Machinery unveiled its PDI (Pre-Delivery Inspection) digital inspection system at the 7th Science and Technology Innovation Conference, providing standardized and digital quality inspection tools for aerial work platform rental companies. The system has entered markets such as Europe and Southeast Asia for multi-batch customer trials and has completed phased validation in actual equipment inspection and handover scenarios.
In aerial work platform rental scenarios, equipment turnover is frequent with numerous handover points. Quality inspection has long relied on service teams' manual experience, leading to inconsistent standards and risks of missed inspections or perfunctory checks. Paper documents are also prone to loss or damage, making it impossible to provide complete records when equipment malfunctions or disputes arise during cross-site handovers. The PDI digital inspection system integrates inspection items, operational procedures, and result records into digital management, achieving standardized and traceable inspection processes.
Inspectors can establish a data connection with the equipment by scanning a QR code using a tablet terminal, follow system guidance to complete all operational condition checks, and automatically generate tamper-proof standardized reports upon completion. The system supports offline inspection, adapting to construction sites with poor network connectivity and various overseas site conditions. Unified inspection standards are globally applicable, facilitating compliance with local safety inspections and regulatory filings.
The PDI system is tailored to the rental equipment turnover scenario, featuring five inspection modules covering key processes such as warehouse acceptance, rental handover, periodic maintenance, and return re-inspection. In structural visual inspection, the system guides inspectors to examine components like pipelines and screws one by one, pre-marking high-risk areas to facilitate the detection of hidden issues such as looseness or wear. For full-machine functional performance inspection, the system checks operational speed and smoothness by on-site operations such as lifting and boom extension. Ground control operation testing conducts full-function tests on the ground control panel, verifying button sensitivity and equipment response speed. Platform control operation testing switches to re-inspect control functions on the aerial work platform, ensuring stable operation in both ground and elevated scenarios. Safety protection special testing simulates scenarios like overload and slope driving to verify whether safety protection devices trigger correctly.
Customer test data shows that the PDI system improves overall equipment inspection efficiency by over 15% and reduces paper record-keeping workload by 95%. The system lowers the threshold for quality inspection, allowing new employees to operate with simple training, no longer relying solely on experienced personnel. With dual local and cloud storage modes, inspection records are permanently retained and tamper-proof, clarifying equipment handover responsibilities and helping reduce disputes while meeting safety regulatory audits.
In the future, the system will continue to iterate with features such as big data prediction, full-process maintenance linkage, and multilingual global adaptation, connecting the entire chain of equipment inspection, maintenance, and spare parts management.
