Trimble LR410 Laser Receiver is a machine-control laser receiver designed for 2D construction-grade control applications. Mounted to an electric mast on a machine blade and connected to the machine hydraulics, the LR410 helps automatically control blade lift to achieve approximately 3–6 mm (0.01–0.02 ft) accuracy for precise grading and elevation control.
Key Benefits
- Precise elevation control: Supports approximately 3–6 mm accuracy for machine lift control.
- 2D machine control: Designed for construction equipment using 2D grade-control systems.
- Automatic blade lift control: Works with compatible machine hydraulics to help maintain the required elevation.
- Laser-based grade reference: Receives laser elevation information for accurate grading applications.
- Improved grading consistency: Helps maintain a more consistent finished grade across the work area.
- Reduced manual adjustment: Automatic machine control can reduce the need for continuous blade-height corrections by the operator.
- Construction-ready application: Designed for demanding earthmoving and grading environments.
Key Features of the LR410 Laser Receiver
High-Accuracy Machine Control
The Trimble LR410 is designed to provide elevation information with an accuracy of approximately 3–6 mm (0.01–0.02 ft). This allows compatible machine-control systems to make precise blade-lift adjustments during grading.
2D Grade Control
The LR410 is intended for 2D machine control and grade control applications, making it useful where a laser reference is used to establish the required elevation or grade.
Electric Mast Installation
The receiver is mounted to an electric mast positioned on the machine blade. This setup allows the receiver to track the laser reference as the blade moves across the work area.
Hydraulic Blade Control
When integrated with a compatible machine-control system, the receiver provides elevation information used to control the machine hydraulics. This helps automatically adjust blade lift to maintain the target elevation.
