Key Features & Design Advantages
Box Girder Structural Strength
The box-type construction utilizes Q235B/Q345 carbon structural steel plates welded into a rigid box configuration that provides exceptional resistance to the bending forces encountered when lifting heavy granite slabs . This design offers several advantages for granite applications:
- Superior load distribution across the entire crane structure
- Enhanced rigidity for precise material positioning during delicate operations
- Reduced deflection compared to alternative designs, critical when handling expensive granite materials
- Extended service life through robust construction and multiple protective paint coatings
Cantilever Functionality for Granite Operations
The incorporation of cantilevers significantly enhances the crane’s functionality in granite handling scenarios:
- Extended operational range allows the crane to service areas beyond the main gantry structure, particularly useful for loading/unloading trucks alongside processing areas
- Protection against structural deformation when handling loads at the extreme ends of the crane’s reach
- Increased workspace utilization by enabling storage or processing directly under the cantilevered sections
Specialized Components for Granite Applications
- Dustproofing devices protect critical components from granite dust, a significant concern in stone processing environments
- Precision positioning systems enable accurate placement of granite slabs during intricate processing operations
- Low-noise operation maintains a better working environment despite the heavy-duty nature of operations
- Anti-sway technology prevents pendulum motion that could damage valuable granite materials during movement
Safety Features for Demanding Environments
Granite handling presents unique safety challenges due to the substantial weights and value of materials being moved. Dongqi’s 10-ton box type gantry crane incorporates multiple safety systems specifically engineered for these demanding conditions:
- Overload protection devices that provide audible alarms and prevent dangerous lifting conditions
- Dual limit switches preventing over-lifting or over-lowering of the hook assembly
- High-quality polyurethane buffers to absorb energy during travel limit engagements
- Emergency stop systems with instant braking capability for critical situations
- Current overload protection to prevent motor damage during demanding operations
- Comprehensive electrical protection (IP54 rating) against environmental contaminants
Applications in Granite Industry
This specialized gantry crane serves multiple critical functions within granite processing facilities:
Raw Material Handling
- Unloading granite blocks from transportation vehicles
- Transferring raw blocks to storage areas or primary processing stations
Production Process Support
- Positioning granite slabs on cutting and polishing equipment
- Transferring work-in-process materials between processing stations
- Handling of finished slabs with precision to prevent edge damage
Finished Product Management
- Stacking finished granite slabs in storage yards with precision
- Loading processed granite for shipment to customers
- Reorganizing inventory with minimal handling damage
Comparative Advantage: Why Choose This Configuration for Granite Applications?
When compared to standard gantry cranes without cantilevers, the 10-ton box type gantry crane with cantilever offers specific advantages for granite industry applications:
- Space Optimization: The cantilever design enables granite storage directly beneath the extended sections, maximizing yard utilization
- Operational Flexibility: Ability to service multiple workstations from a single crane position reduces handling time
- Structural Protection: The cantilever design provides additional protection to the crane’s legs from deformation when handling loads at the extreme edges of the operating area
- Weather Resistance: The box girder construction provides better performance in outdoor granite yards compared to alternative designs
Customization Options
Dongqi offers various customization options to tailor the crane to specific granite factory requirements:
- Cantilever configuration: Single or double cantilever designs based on facility layout
- Control systems: Cabin control, remote control, or automated operation options
- Span and height adjustments: Custom dimensions to fit specific facility constraints
- Specialized lifting attachments: Custom hooks, grabs, or slings designed specifically for granite blocks and slabs
