The Load Rotation Device (LDR) is a special device that reorients a unit load on the conveyor. The rotation device itself consists of the rotation means, the lift frame and its lifting mechanism, and a fixed frame. The LDR may act as part of a modular conveyor system or as a stand-alone unit that includes its own conveyor drive means.  

The rotation means consists of a ring weldment with four cross members that support the load during rotation. The ring is supported and guided from the lift arm by a series of rollers. The ring is encircled by a power transmission chain that is pulled by a sprocket and gear motor that is supported by the lift frame. The lift frame is supported by air actuators that raise the rotation device and lift the load when compressed air is introduced. This lift mechanism is controlled during the lifting by a load-stabilizing mechanism attached to the base frame that prevents uneven lifting.  

The fixed frame supports the load-carrying rollers and the pressure rollers that support and engage the conveyor drive belt. The center rollers and full-length rollers at either end of the device are driven by the belt and move any loads along the conveyor when engaged. 

The LDR is often used as part of a unit banding operation, where it is necessary to reorient the load before applying cross straps. The addition of this device between the strapping machines allows rotation to be accomplished without occupying the strappers themselves and can greatly improve throughput in such an operation. 

Features 

• Low profile, 12″ TOR minimum.  
• For use with New or existing Mainline conveyor or other center belt drive conveyor.  
• Loads are fully supported around perimeter of the ring.  
• Improved lift stabilizing mechanism greatly reduces uneven lifting thereby improving stability of load. 
• 2 speed rotation drive decreases cycle time while improving position control.  
• Alternate 1 HP variable frequency rotation drive also available.  
• Rotates continuously in one direction without re-rotating between loads.  
• Units may be provided as a module of an overall conveyor or as a stand alone unit with a self-contained conveyor.  
• Motor disconnect switch and position limit switches are prewired for easy installation. 

Cost 

• 72” between frames 
• 84” between frames.  
• Approx: $17,000.00   

Mesh Belt Loaded Rotation

• Low profile, 12″ TOR minimum, self contained conveyors.
• For use with new or existing conveyor systems of any manufacturer.
• Loads are fully supported by the conveyor during rotation.
• Eliminates lifting and lowering of loads for rotation, thereby shortening the rotation cycle time.
• Dual conveyors allows wide conveyor support for large loads
• Rotates continuously in one direction without re-rotate between loads.
• Can be provided as a unit or as a field assembly.
• Variable speed conveyor drives improve cycle time while improving position control.
• Motor disconnect switches and position sensors are pre-wired for easy installation.
• Mesh belt conveyor provides stable surface for operators to access the load from on top of the conveyor.
