Grab-type double-girder overhead crane: an "efficient hand in the air" for bulk material handling
Classification:
Product Introduction
In areas such as port bulk cargo handling, metallurgical raw material transshipment, and warehouse powder handling, efficient handling of bulk materials (such as ore, coal, waste, and grain) is a core pain point in production and logistics. Traditional methods are either inefficient or result in excessive material residue and high operational risks.
Technical Parameters:
| Lifting Capacity | 5 t～500 t (including grab bucket weight, larger tonnage can be customized according to the scenario) |
| Span Range | 7.5 m～40 m (adapt to different factory/site span requirements) |
| Work Duty | A 5 to A 8 (A 5 is for medium-intensity operations, A 8 is suitable for high-frequency, heavy-duty conditions, such as continuous loading and unloading at ports) |
| Grab Bucket Volume | 0.5 m³～50 m³ (matched with the lifting capacity, determines the single grab amount) |
| Grab Bucket Lifting Speed | 3 m/min～20 m/min (slow rise for heavy loads, fast rise for light loads, balancing work efficiency and stability) |
This grab-type double-girder overhead crane, with its combination of "stable double-girder load-bearing capacity and flexible grab loading and unloading," has become a powerful tool for bulk material handling, making aerial transfer both powerful and precise! 1. Grab: "One-touch, Full, Complete Discharge"—The "Key to Loading and Unloading"
The grab is the core component of material loading and unloading (the multi-petal grab in the picture has excellent gripping capabilities for irregular bulk materials):
Efficient Grabbing: Rapid opening and closing through hydraulic/mechanical actuation allows for a single grab to fill bulk materials like ore and coal, significantly reducing loading and unloading time.
Complete Discharge: Precisely controllable opening and closing angles and force ensure a clean, virtually residue-free discharge, eliminating material waste and subsequent cleanup costs.
Wide Application Compatibility: From hard ore to loose grain, from high-temperature metallurgical waste to moist sludge, a wide range of bulk materials and shapes can be matched to a corresponding grab (multi-petal, clamshell, or orange-slice). 2. Double-Girder Structure: "Rock-Solid" Heavy-Load Guarantee
The double-girder bridge-style structural design provides a solid foundation for "heavy loads and stable operation":
Superior Load Capacity: Two main beams, supplemented by secondary beams and end beams, form a stable framework with a rated lifting capacity ranging from 5 t to 500 t (customizable upon request), easily carrying large-tonnage grabs and materials.
Smooth Operation: The main beam is constructed of high-strength steel, such as Q345B, and undergoes precision welding and heat treatment for superior deformation resistance. Combined with the precise trolley and carriage mechanisms, the grab remains stable and stable during horizontal and vertical movement, preventing material spillage.
Excellent Space Utilization: The double-girder structure accommodates varying factory building height restrictions, while also leaving ample space for vertical operation of the grab, allowing for flexible workshop layouts. III. Multi-Scenario "All-in-One," Unlocking New Efficiency in Industrial Handling
From ports and terminals (unloading coal and ore from ships/trucks, increasing throughput), to metallurgical plants (transferring iron ore fines and steel slag, adapting to high-temperature and dusty environments), to warehousing and logistics (storing grain and fertilizer for precise unloading), grab-type double-girder overhead cranes offer comprehensive coverage:
Port scenarios: A single overhead crane increases daily loading and unloading capacity several times compared to traditional methods, contributing to efficient port operations;
Metallurgical scenarios: Withstands high temperatures and high dust levels, ensuring continuous transfer of raw materials and waste across production lines;
Warehousing scenarios: Combined with intelligent systems, it enables "targeted grabbing and precise unloading," improving warehouse management. IV. Intelligence + Safety: Making Heavy-Load Operations More Worry-Free
Beyond its "carrying and grabbing" capabilities, the equipment incorporates intelligent and safe design features:
Intelligent Control: Supports both ground remote control and cab-based operation. The cab is equipped with high-definition monitoring and a precise weighing system, allowing the operator to clearly observe the bucket status and accurately monitor material weight in real time, helping to prevent overloading.
Safety Protection: Equipped with a load limiter, travel limiter, anti-derailment device, and emergency brake, these devices provide multi-dimensional operational safety against overloads, overruns, and malfunctions, providing confidence and peace of mind when handling heavy loads.
