Topcon LS-B110 Laser Machine Display Receiver

Overview

The Topcon LS-B110 Laser Machine Display Receiver (Model 312670111) represents a significant advancement in machine control technology for grading and paving operations. This dual-axis laser receiver goes far beyond basic elevation control, incorporating integrated plumb and tilt indication that empowers operators to maintain precise slope control simultaneously across both the cross-slope and longitudinal axes. Whether you're fine-grading a complex parking lot with multiple drainage planes or paving a superelevated highway curve, the LS-B110 delivers the real-time feedback necessary to achieve specification-grade results on the first pass.

What sets the LS-B110 apart from conventional single-axis receivers is its ability to display dual-plane positioning simultaneously. The large, high-visibility LED display shows both elevation and cross-slope status, allowing operators to make coordinated adjustments without toggling between display modes or relying on separate instruments. This integrated approach dramatically reduces the learning curve for operators transitioning from traditional grading methods while significantly improving productivity on projects requiring complex surface geometries.

Built to withstand the demanding conditions of construction sites, the LS-B110 features rugged, weather-resistant construction with an IP66 rating for dust and water protection. The receiver mounts securely to grader blades, dozer blades, or paver screeds, providing consistent performance through vibration, temperature extremes, and the inevitable impacts of daily machine operation. For contractors seeking to eliminate costly grade checking delays and rework while improving finished surface quality, the LS-B110 delivers an exceptional return on investment.

Job Applications

• Motor Grader Finish Grading: The dual-axis capability excels on projects requiring precise cross-slope control such as crowned roads, ditches, and drainage channels. By monitoring both elevation and tilt simultaneously, operators can achieve final grade in fewer passes, reducing fuel costs and equipment hours while improving surface quality that meets or exceeds specifications.
• Asphalt Paving Operations: Maintaining consistent mat thickness and proper cross-slope on paving projects is critical for drainage performance and pavement longevity. The LS-B110 provides paver operators with instant feedback on both screed elevation and angle, ensuring uniform compacted thickness and eliminating the birdbaths and grade breaks that lead to premature pavement failure and costly callbacks.
• Parking Lot and Pad Construction: Complex grading projects with multiple drainage planes, such as shopping center parking lots or industrial pads, demand precise multi-directional slope control. The LS-B110's integrated tilt sensing eliminates the need for constant grade checking with survey equipment, allowing operators to confidently work to plan while inspectors verify finished work rather than staking every grade break.
• Sports Field and Athletic Facility Grading: Athletic fields require exceptionally tight tolerances and precise crown or slope configurations for proper drainage and playability. The LS-B110 enables contractors to achieve these demanding specifications efficiently, whether establishing the crown on a baseball infield or grading the multi-directional slopes of a synthetic turf field base.
• Airport Runway and Taxiway Construction: Aviation projects demand exacting grade tolerances with complex longitudinal and transverse slope requirements. The LS-B110's accuracy and dual-axis monitoring capability helps contractors meet FAA specifications while maintaining the productivity necessary to complete work within restricted construction windows and tight project schedules.
• Canal and Irrigation Channel Grading: Agricultural and water management projects require consistent slope control over extended distances to ensure proper flow characteristics. The LS-B110's extended working range and reliable slope indication enable operators to maintain design grades on both channel bottoms and side slopes, reducing surveying time and improving hydraulic performance of completed installations.

FAQ

What's the difference between the LS-B110 and a standard single-axis laser receiver?

The LS-B110 incorporates built-in tilt sensors that monitor cross-slope and longitudinal grade simultaneously, displaying both elevation position relative to the laser plane and the actual tilt angle of your blade or screed. Standard single-axis receivers only show elevation (up/down position) relative to the laser plane. This dual-axis capability is essential for finish grading applications where you need to maintain a specific slope while also controlling elevation, such as grading crowned roads or sloped parking lots.

Can I use the LS-B110 with my existing rotary laser, or do I need a specific Topcon laser?

The LS-B110 is compatible with any standard rotating laser that operates on conventional laser frequencies, including models from Topcon, Trimble, Leica, and other manufacturers. However, for dual-slope applications, you'll achieve optimal results when paired with a dual-slope capable laser like the Topcon RL-SV2S. The receiver will work with single-slope lasers as well, utilizing its internal tilt sensors to provide slope indication independent of the laser plane.

How difficult is it to install and calibrate the LS-B110 on my grader or paver?

Installation typically takes 1-2 hours for someone familiar with basic machine controls. The universal mounting bracket attaches to your blade, mast, or screed using the included hardware, and the power cable connects to your machine's electrical system (10-30V DC). Initial calibration involves setting the receiver to recognize your desired grade and slope values, which is accomplished through the straightforward button interface following the quick-start guide. Most operators become proficient with the system within a few hours of use.

What kind of accuracy can I expect in real-world grading conditions?

Under typical job site conditions with a quality rotary laser, the LS-B110 provides elevation accuracy within ±1/16 inch (±2mm) and slope indication accurate to within 0.1 degrees. Actual accuracy depends on several factors including laser quality and calibration, distance from the laser, atmospheric conditions, and machine vibration. For most commercial grading applications, the LS-B110 delivers more than sufficient precision to meet project specifications while significantly outperforming traditional grade-checking methods in both speed and consistency.
