Production of 5 Ton Single Girder Gantry Crane
After in-depth communication with the customer, we confirmed the factory site size, daily operation frequency, marble handling characteristics and customized requirements. Our technical team carried out targeted personalized optimization for the customer’s long-term frequent marble slab lifting scenario and indoor factory working conditions. Different from ordinary standard gantry cranes, this equipment is upgraded to A5 high working grade, which features strong load resistance, excellent fatigue resistance and durable performance, fully meeting long-term high-frequency factory operation needs and prolonging equipment service life. Meanwhile, the whole machine adopts full variable frequency speed regulation system, realizing stepless smooth speed adjustment for lifting and traveling. It thoroughly solves the problem of start-stop jitter and operational impact of traditional gantry cranes, ensures ultra-stable lifting of heavy and fragile marble slabs, completely avoids stone breakage losses, and adopts a compact and streamlined overall structure to adapt to the customer’s compact factory space without occupying excess production area.
After the customer confirmed the technical drawings, structural parameters and customized schemes, the production department launched standardized production in strict accordance with international export standards. The main beam, end beam, electric hoist and core electrical components of the gantry crane all adopt high-quality brand accessories, with strong structural rigidity, wear resistance and stable operation. The whole machine is painted with anti-rust and wear-resistant industrial paint, which is suitable for long-term indoor factory working environment and effectively extends the service life of the equipment.
During the production process, the quality inspection team carried out full-process multi-standard inspection, including raw material incoming inspection, welding quality flaw detection, structural assembly calibration, no-load test, full-load lifting test, and safety device debugging. For the marble handling scenario, we specially tested the gantry crane’s stable lifting performance at different speeds to ensure no jitter during the lifting and traveling process of heavy marble slabs. All performance indicators of the crane equipment meet export standards and the customer’s on-site use requirements, and the production and quality inspection work was completed on schedule to ensure timely shipment.
