PRODUCTS & CASES

The QZ grab bucket overhead crane is a high-efficiency industrial lifting equipment engineered for bulk material transportation, covering coal, ore, grain, sand and other granular and loose materials. Fitted with an intelligent automatic grabbing system, the equipment supports fast, uninterrupted and precise loading and unloading, perfectly adapting to high-intensity industrial working scenarios.

Adopting a rugged double-girder bridge structure paired with an electric traveling trolley and optimized electrical control system, this crane delivers superior structural stability and heavy load-bearing performance. The bridge travels along fixed runway rails, while the trolley performs lateral movement on the main girders, achieving full coverage of the working area and accurate operational positioning.

As the core functional component, the supporting grab bucket completes material grabbing, hoisting and discharging efficiently. Multiple grab specifications are available to match different material properties, ensuring adaptive and optimal handling performance for diverse working conditions. Equipped with upgraded intelligent electrical systems, the crane realizes accurate motion control and smooth operation with comprehensive safety guarantees. Built-in automatic positioning and intelligent grab opening and closing functions greatly elevate overall working efficiency and reduce manual intervention.
