Bobcat BLR2 Laser Receiver: Enhancing Grading Precision

[MikePhua]

The Bobcat BLR2 Laser Receiver is a pivotal component in modern grading operations, offering enhanced precision and efficiency for operators. Designed for use with Bobcat M-Series compact track loaders, this system integrates seamlessly with the 96-inch and 108-inch grader attachments, facilitating automatic or indication-based grade control.

System Overview
The BLR2 Laser Receiver operates in conjunction with a laser transmitter, typically mounted on a tripod, to establish a reference plane for grading. The receiver, affixed to the grader attachment, detects the laser signal and communicates with the loader's instrumentation panel to adjust the blade's position accordingly. This setup allows for precise grading with minimal operator intervention, reducing labor costs and enhancing surface quality.

Key Features

• Automatic and Manual Control Modes: Operators can switch between automatic grade control and manual indication modes, providing flexibility based on job requirements.
  
• In-Cab Instrumentation Panel: Displays real-time grade information, allowing operators to make adjustments without leaving the cab.
  
• Incremental Grade Adjustments: Enables fine-tuning of the blade position in 0.1-inch increments, facilitating precise grading.
  
• Dual Receiver Setup: On grader attachments, two receivers are used to independently control each side of the blade, ensuring consistent grade across the entire width.
  

Installation and Compatibility
Installing the BLR2 Laser Receiver involves mounting the receiver on the grader attachment's mast and connecting it to the loader's electrical system. Compatibility is primarily with Bobcat M-Series loaders, including the 600, 700, and 800 platforms. It's essential to verify compatibility with specific models and serial numbers to ensure proper functionality.

Troubleshooting Common Issues
Operators may encounter various issues with the BLR2 system, including:

• Receiver Not Powering On: Ensure the power cable is securely connected and the fuse is intact.
  
• Inaccurate Grade Control: Check the alignment of the laser transmitter and ensure the receiver is properly mounted and level.
  
• Communication Errors: Verify all wiring connections and inspect for any damage or wear.
  

Consulting the Bobcat Grader Service Manual can provide detailed troubleshooting steps and solutions.

Maintenance Recommendations
Regular maintenance is crucial for the longevity and performance of the BLR2 system:

• Clean the Receiver and Transmitter: Use a soft cloth to remove dust and debris, preventing interference with the laser signal.
  
• Inspect Wiring and Connections: Regularly check for signs of wear or corrosion to maintain reliable communication.
  
• Calibrate the System: Periodically calibrate the laser system to ensure accurate grade control.
  

Conclusion
The Bobcat BLR2 Laser Receiver significantly enhances grading operations by providing precise and efficient grade control. By understanding its features, installation requirements, and maintenance needs, operators can maximize the system's benefits, leading to improved productivity and quality in grading tasks.
