The QZ Grab Bucket Overhead Crane is a high-efficiency lifting solution specially designed for handling bulk materials such as coal, ore, grain, and sand. Equipped with an automatic grab system, it enables fast, continuous, and precise loading and unloading operations in heavy-duty industrial environments.
This crane features a robust double girder bridge structure combined with an electric trolley and intelligent control system, ensuring excellent stability and load-bearing capacity. The bridge travels along runway rails, while the trolley moves horizontally on the girders, allowing full coverage and accurate positioning within the working area.
The grab bucket is the core working device, designed to efficiently grab, lift, and release bulk materials. It supports various grab types depending on material characteristics, ensuring optimal performance in different handling scenarios.
Equipped with advanced electrical control systems, the crane provides precise motion control, smooth operation, and enhanced safety. Automation features such as automatic positioning and grab opening/closing significantly improve operational efficiency.
