The QD type 400/80 - 450/80 ton hook bridge crane is a high-performance, large-tonnage double-girder bridge crane, which is highly suitable for heavy-load and high-precision operation scenarios. The following is an introduction to this model of crane:
Technical Specifications
Rated lifting capacity: 400/80 to 450/80 tons
Span: Can be customized according to requirements, usually 22.5 meters
Lifting height: 18 meters (can be adjusted according to requirements)
Working class: A5-A6
Travel speed of the main trolley: 28.5 meters per minute
Travel speed of the small trolley: 86 meters per minute
Lifting speed: Main hook 13.3 meters per minute, auxiliary hook 26.7 meters per minute Core
Strengths
High carrying capacity: The rated lifting capacity has a wide coverage range. The "anti-overturning moment" and "anti-bending stiffness" of the double main beam structure are 3-5 times that of similar products, ensuring that the main beam deflection is controlled within the safe range during full-load operation.
High operation accuracy: Using "variable frequency speed regulation + encoder positioning", the positioning error can be controlled within ±2mm, meeting the requirements of precise operations. At the same time, the lifting mechanism adopts a "double braking system" to ensure no impact during start-up and shutdown.
Strong functional scalability: Supports the installation of various auxiliary systems, such as precise weighing, rotational hoisting, and synchronous control, to adapt to complex scenarios.
High environmental tolerance: The motor and electrical cabinet adopt high protection level design, capable of withstanding harsh working conditions. Outdoor-type cranes can be equipped with wind-resistant rail-fixing devices to withstand strong winds.
Application scenarios
The QD type 400/80 - 450/80 ton hook bridge crane is suitable for various scenarios, especially in industries such as heavy machinery manufacturing, metallurgy, power, and ports and logistics hubs. In these scenarios, the crane needs to handle large-tonnage loads, high-precision positioning, and complex working conditions. The QD type crane can meet these requirements.
