Designed to be used with the included Spectra RD20 Wireless Remote Display, the Spectra LR50W Machine Control Receiver allows you to check grade information without leaving the cab. This standalone display receiver features versatile 360-degree laser reception and integrated blade tilt and plumb indicator. It also works with all types of rotating lasers on all kinds of machinery, such as dozers, excavators, backhoes, scrapers and box blades.
Blade Tilt and Plumb Indicator
The LR50W’s built-in blade tilt indicator helps you keep the blade level for increased accuracy. This feature is also programmable to match an existing or known grade for slope matching operations. The LR50W also has an integrated plumb indicator for fast and accurate grade checking on excavators and backhoes.
LED and Display Channels
Adjustable, ultra-bright LED with green on-grade display provides you with clear viewing to match ambient lighting conditions. In addition, moving and getting back in the beam is easy with six channels of grade information and a directional out-of-laser beam indicator.
Choice of Accuracy
With three accuracy settings – fine, medium and coarse, this Spectra machine control receiver gives you maximum flexibility by allowing you to work to the tolerances demanded by the job. It also features offset on-grade that gives you more range above grade for a more productive excavation.
Spectra RD40 Wireless Remote Display
The included RD40 provides construction professionals with an in-cab display of elevation and audible signals. With built-in radio frequency technology, this wireless remote display mounts to your machine and eliminates the need for an assistant to check grade, increasing productivity and safety.
The touch panel buttons function primarily to select blade-tilt indication, on-grade location, dead band, plumb indication and display brightness. Their secondary functions are laser-beam averaging and laser out-of level warning.
Highly Accurate Laser Strike Positions
To precisely measure the actual height deviation from on-grade, the LR50W laser receiver provides a continuous, absolute laser strike position to provide the highest accuracy and grade performance.
The large front-facing knobs allow for quick and hassle-free installation to a round pipe or square tubing. You also have the option for a magnetic mount or bolt-on bulldozer mount from the drop down menu in the upper right hand corner of this page.
Shockproof and Water Resistant
Made of tough aluminum polycarbonate housing, the LR50W is protected against harsh jobsite conditions. This laser detector automatically shuts off after 75 minutes of inactivity and works up to 45 hours using the included rechargeable NiMH batteries and approximately 60 hours using four C alkaline batteries.
This Spectra Precision wireless machine control receiver comes with an RD20 remote display, hard carry case, rechargeable batteries, charger and 2-year manufacturer's warranty.
