Full Description

The Topcon RL-2002S Grade Laser is developed for applications where precise slope and elevation control are critical to project success. Commonly used on civil engineering, infrastructure and large-scale construction works, it provides a stable and repeatable reference for grading and earthmoving operations. The RL-2002S supports single-axis slope control, allowing operators to introduce controlled fall across a working area for tasks such as drainage runs, road formation and groundwork preparation. This makes it particularly effective on projects where maintaining a consistent gradient over distance is essential. When paired with compatible laser receivers or machine control systems, it supports both manual and automated grading workflows. A robust self-levelling system helps the laser stabilise quickly after setup and maintain accuracy in challenging site conditions, including vibration from nearby plant or uneven terrain. The instrument is housed in a heavy-duty, weather-resistant casing, designed to protect internal components from dust, moisture and everyday site impacts. Clear controls and a logical layout support efficient setup and adjustment, reducing downtime when grade requirements change. Supplied in a protective carry case, the Topcon RL-2002S is well suited to grading, earthworks, civil engineering, groundworks, and infrastructure projects where dependable slope accuracy and durability are essential.

FAQs

What is the working diameter of this laser?

The RL-2002S boasts an incredible working range, allowing for a diameter of up to 1,100 metres. This massive coverage area means you can set the laser in a central location on even the largest civil sites and maintain accuracy without having to relocate your base station.

What makes the RL-2002S different from standard dual grade lasers?

The RL-2002S is a high-accuracy, high-power grade laser designed specifically for long-distance applications. It offers a higher degree of precision and a more powerful beam than standard units, making it the go-to choice for large-scale land levelling and major highway projects.

What is the maximum grade range of the RL-2002S?

This instrument is built for versatility, offering a wide grade range from -5% to +25% in the Y-axis. This makes it suitable for everything from subtle drainage falls to steep embankment work and specialised agricultural grading.

Does it feature a remote control for one-man operation?

Yes, a full-function RC-400 remote control is available. This allows the operator to change grades and adjust settings from up to 300 metres away, which is essential for maintaining productivity when working across expansive sites.

How does the “Automatic Alignment” feature work?

When used with a compatible receiver, the RL-2002S can automatically align the laser beam to the centre of the receiver. This simplifies the setup process for grade matching, ensuring that your reference line is perfectly calibrated to your existing site markers.

Is the RL-2002S compatible with machine control systems?

Absolutely. Due to its high-power beam and stable rotation speeds (up to 900 rpm), it is the ideal transmitter for machine control sensors on dozers, graders, and scrapers, providing the consistent, long-range signal required for automated 3D grading.

How rugged is the housing for heavy-duty construction use?

The unit is built to withstand the harshest environments, featuring an IP66 rating. It is completely protected against dust and can handle powerful jets of water, ensuring it continues to perform in heavy rain or on sites with high levels of airborne debris.

Where can I get my RL-2002S serviced or calibrated?

PQS Survey Ltd provides expert calibration and repair for the RL-2002S at our specialist depots. Given the high-accuracy requirements, regular calibration is vital to ensure it meets the strict tolerances needed for major infrastructure works.

What power options are available for long-term site use?

The RL-2002S is typically powered by a high-capacity rechargeable battery pack, providing up to 90 hours of continuous operation. It can also be powered via a DC cable directly from a 12V source, common for permanent machine control base stations.

Can I hire the RL-2002S from PQS Survey Ltd?

Yes, we offer the RL-2002S for both short and long-term hire. It is the perfect solution for contractors who need a high-power, long-range laser for a specific large-scale project without the capital expenditure of a full purchase.
