The QZ Electric Grab Bridge Crane is engineered for precision handling of bulk materials in demanding industrial settings. Its core structure features a reinforced box-type bridge, providing superior strength and resistance to fatigue under continuous heavy loads. The system integrates a specialized grab trolley, a precisely controlled trolley travel mechanism, an operator cabin, and an advanced electric control system.
Central to its operation is the grab trolley, which houses two independent mechanisms: a swiveling (or opening/closing) mechanism and a hoisting mechanism. The grab is suspended by four steel wire ropes. The operational cycle begins with the swiveling mechanism activating to close the grab, securely enclosing the material. Once closed, the hoisting mechanism immediately engages, lifting the evenly loaded grab. For discharge, the swiveling mechanism re-engages to open the grab and release the payload efficiently.
This crane shares the robust foundational design of standard hook bridge cranes but is specifically differentiated by its automated grab system.
Key Technical Features:
Customized Capacity Solutions: Designed and built to support specific customer capacity upgrade plans, this crane facilitates a transition to more productive and environmentally conscious industrial operations, with configurations tailored to your unique site layout.
Intelligent Control for Precision: An integrated PLC control system, combined with advanced positioning and anti-sway technology, ensures pinpoint load placement and smooth, high-efficiency movement cycles.
Robust Construction for Harsh Conditions: The crane's wide-box weight-bearing design offers exceptional durability and longevity. It is built to maintain reliable performance in challenging environments, including exposure to high temperatures, significant humidity, and dense fog.
Enhanced Autonomy in Low Visibility: Through its intelligent sensor suite, the crane performs automated grabbing, transporting, and unloading of materials even in low-visibility conditions, such as heavy fog, where manual operation would be hindered.
Remote Operation & Management: Enable full remote control and scheduling via a centralized management system. This eliminates the need for personnel to be physically present in the operational area, significantly enhancing safety and reducing manual labor requirements.
The Grab Double Girrier Overhead Crane specializes in handling bulk materials through its unique grab mechanism, which securely captures and transports loose substances in demanding industrial environments. Recent innovations from Henan Mine Crane have advanced intelligent, eco-friendly, and lightweight designs, with proven deployments across critical sectors including steel production, aerospace manufacturing, and petrochemical processing.
A notable collaboration with Guangxi Yiji Iron and Steel highlights the crane’s role in supporting industrial modernization—specifically in establishing a 10-million-ton metallurgical new material base. This partnership underscores a shared commitment to technological advancement and sustainable industrial growth.
