Recently, the QD40T-46.5M double-girder bridge crane, manufactured by Shenghua Group, has been successfully dispatched. As a flagship model of the company, this equipment relies on a mature design and manufacturing system, making it a highly reliable choice for heavy-duty operations in large-span industrial plants.
The device adopts a box type double beam structure, which has strong rigidity and long service life under a large span of 46.5 meters; High strength bolt connection, convenient transportation and assembly, compared to single beam models, the bearing capacity and operational stability have been comprehensively upgraded, and it can stably support high-frequency continuous operations of 40 tons.
01 Lifting mechanism
The winch system is equipped with a hard tooth surface reduction transmission, dual brake safety redundancy design, smooth start stop, and precise and controllable lifting alignment.
02 Operating mechanism
Split type drive with forged wheel set, supporting variable frequency speed control, with low start stop impact, low operating noise, and slower component wear.
03 Electrical System
Adopting industrial grade core components, it has high integration and strong anti-interference ability, built-in multiple safety protection logic, and supports multiple control modes.
Relying on a standardized manufacturing system, the entire process follows unified quality standards: cutting and welding: cutting to ensure component accuracy, combined with full inspection and testing, the structural quality is stable and reliable. Anti corrosion coating: With multiple anti-corrosion coating processes, the paint film has excellent adhesion and weather resistance, and can adapt to various types of factory operating environments. Factory verification: Multiple rounds of joint acceptance by various departments must be completed before leaving the factory, and all performance parameters must be verified and qualified before shipment.
Widely applicable: covering equipment manufacturing, metallurgy and building materials, warehousing and logistics, automobile production, energy and chemical industries, etc., it can meet various lifting operation needs such as material transportation, equipment maintenance, and finished product lifting. Customized elasticity: The lifting height, working level, and operating speed can be adjusted as needed, supporting the expansion of special protection schemes such as explosion-proof, anti-corrosion, and insulation, and adapting to various non-standard working conditions.
The QD series products of Shenghua Group have undergone multiple rounds of technological iteration and have formed a complete product matrix covering multiple tonnages and spans, which can quickly respond to the equipment needs of customers of different scales. Since the beginning of this year, the company’s orders for large tonnage and large-span bridge cranes have steadily increased, and multiple units of the same type of equipment have been delivered to core customers in various industries, helping to support infrastructure projects across the country.
Reliable overload, adaptable to all domains. Shenghua Heavy Machinery QD series double beam bridge crane meets the heavy-duty lifting needs of multiple industries with standardized manufacturing quality and customized adaptability. Shenghua Heavy Machinery adheres to the principle of precision manufacturing of heavy machinery, and with the strength of hard core products, helps customers produce efficiently and smoothly.
