Quality inspection is carried out throughout production rather than only at the final stage. Key structures, machined components, welding areas, hydraulic pipelines, electrical systems, and major assemblies are checked during manufacturing and assembly.
Before shipment, the finished drilling rig undergoes operational testing. The inspection normally covers the power system, hydraulic system, control response, crawler movement, drilling structure, support legs, gauges, pipelines, and safety-related components.
The machine configuration, accessories, spare parts, and order requirements are also verified before packing. This structured inspection process helps ensure that the equipment is complete, correctly configured, and ready for delivery.
