Laser Grading

Deliver more accurate grading results while spending less time and less labor on the job with laser-guided grading. When equipped with the laser control system, grading attachments can achieve near-perfect precision. All it takes is the push of a button! Just one operator can eliminate the use of grade rods and transits to continually check grading progress. Laser-guided grading does the work of an entire survey crew.

When connected with the laser control system, the blade moves up and down automatically to keep the base materials on grade. Setting the unit to cut and fill on grade is as simple as setting the desired slope on the transmitter and adjusting the height of the receiver. Laser transmitters � along with hand-held laser receivers � quickly determine the amount of material that needs to be added or removed from the site. The laser control system delivers not only more accurate finish grading, but also more efficient rough grading, maximizing production while increasing the versatility of grading attachments.

How Does It Work?

On the jobsite, the laser transmitter is mounted on a tripod to provide a 360-degree plane of reference at a set elevation and slope. Laser receivers, mounted on a mast attached to the box blade or grader attachment, capture the light from the laser transmitter. When operating in manual control mode, the receivers inform the operator via LED lights when the blade needs to move up or down, or to notify that the blade is on grade. In automatic control mode, the receiver informs the blade that it needs to move up or down to stay on grade.

With the box blade attachment, one receiver � mounted in the middle � moves the entire blade up or down. With the grader attachment, two receivers are mounted so that so each side of the blade will adjust independently.

Single vs. Dual Slope:

For a fully equipped laser grading system, Bobcat offers three laser transmitters � one single slope model and two dual slope models � that will transmit flat, single slope or dual slope functionality. Equip a laser system with the single slope transmitter to deliver excellent results for flatwork or simple grades. Both models of dual slope transmitters work well for anything from flatwork to compound set-ups.

Use the laser control system to increase precision when operating with the box blade or grader attachment. Both box blade and grader work equally well on flat and single slopes. On dual slopes, the grader attachment delivers increased functionality, with each side of the blade operating independently.

Laser Grading Features:

Automatic Laser Control: Requires less operator input and provides better accuracy, less operator fatigue and faster travel speed, delivering maximum ease of use and superior production.
Blade Control: For both the box blade and grader attachments, blade control is offered with either a manual or automatic control option.
Fingertip Controls: Mounted on the carrier�s steering levers, fingertip controls provide quick and easy access to make elevation changes or switch the automatic function on or off, delivering precise and accurate results with maximum operator comfort.
Laser Receivers: Provide visible indication of where the blade is relative to the ground.
Quick Attachment: For ease of use around the jobsite, the laser control system is quickly attached and removed as necessary to complete other worksite operations.

Attachments with Laser Grading

Grader Attachment:

Grade surfaces with precision and control while maximizing productivity with the grader attachment. Designed for use in landscaping, asphalt, curb and concrete flatwork, the grader attachment features blades that move six different ways and a front bolster that oscillates 12 degrees to the right or left, allowing for grading on any surface while minimizing the effect of uneven ground. And with the laser control system, the farther the blade is from grade, the more quickly it will move to grade. Click here to learn more about the Grader Attachment.

Box Blade Attachment:

Control grading operation with the accuracy and durability of the box blade attachment. The box blade incorporates end wings to help carry spoil and features elevation control, which allows the box blade to travel up and down slopes while still delivering accurate results. And with the laser control system, the box blade can tackle the fine grading required for flatwork applications. Click here to learn more about the Box Blade Attachment.

Receivers & Transmitters

BLR2 Receiver: Machine Control

Using CANbus communication, the BLR2 laser receiver provides frequent updates (up to 20 times per second) to the control valve on the attachment, delivering high accuracy grading. Indicators and an automatic light on the face of the receiver also provide constant information to the operator. To make grade changes quickly, the �on grade� setting of the receiver can be moved up or down � up to two inches with certain machine options � for fast, accurate results.

CR600 Receiver: Indication Only

Equipped with a 270-degree signal range, the CR600 provides an easy way to check the grade directly from the operator�s seat. The CR600 is an indicate-only receiver, delivering visible and audible alerts to inform the operator when operating above, below, or on grade. For maximum operating versatility, the CR600 receiver can be hand-held, rod-mounted, or mounted to the carrier using the included magnetic mount. The included mount provides a way to quickly estimate the amount of fill needed to be added or removed. As a rod-mounted unit, the CR600 can be used to check grade and elevation, measure cut and fill, and check vertical alignment.

Laser Transmitters:

For a fully equipped laser grading system, Bobcat offers three laser transmitters: one single slope model and two dual slope models. Each model includes a hand-held laser receiver. All models feature two-way radio remote control to allow adjustments from across the jobsite or from within the machine. All laser transmitters also offer temperature compensation, ensuring the laser beam stays accurate as temperatures change throughout the day. Accuracy on the jobsite is critical, and a quality laser transmitter provides the high accuracy and the quick adjustment features necessary to get the job done right.
