Spectra LR60 & LR60W

The Spectra LR60 and LR60W are advanced 360-degree machine receivers designed for high-speed excavation and grading. Featuring patented Angle Compensation for Excavation (ACE), these units provide accurate grade readings at various dipper arm angles. The “W” variant enables wireless connectivity to an in-cab display.

Patented Angle Compensation for Excavation (ACE) ensures accurate readings at wide angles.
Extra tall 222mm reception window captures the laser beam over a larger vertical range.
Full 360-degree laser reception allows for uninterrupted operation from any machine orientation.
Ultra-bright LED display provides clear visual grade guidance in all site lighting conditions.

Full Description

The Spectra LR60 series is the professional choice for intensive excavation and grading projects across the UK. Equipped with a large 222mm reception window, it maintains signal contact over a wider vertical range, making it ideal for larger machinery. Its standout feature, Angle Compensation for Excavation (ACE), automatically calculates the correct grade even when the dipper arm is tilted, reducing the need for the operator to be perfectly plumb. The LR60W model enhances site safety and efficiency by linking wirelessly to the RD20 in-cab display, allowing for real-time monitoring without leaving the seat. Both models are built with a cast aluminium and polycarbonate housing to withstand the vibrations and impacts of heavy construction plant.

FAQs

How does Angle Compensation for Excavation (ACE) benefit the operator?

ACE technology corrects for the angle of the dipper arm, allowing you to check grade without having to reposition the arm to a perfectly plumb position.

What is the difference between the LR60 and the LR60W?

The LR60W features integrated wireless radio technology, enabling it to transmit grade and plumb data to an RD20 remote display inside the machine cab.

Are the Spectra LR60 and LR60W available for hire?

PQS Survey Ltd offers both models for hire, providing a flexible way for UK contractors to utilise advanced machine control on specific excavation projects.

How does the LR60 compare to the Spectra LR50 model?

The LR60 features a much larger reception window and includes ACE technology, whereas the LR50 is primarily focused on grading with tilt indicators.

What power options are available for the LR60 series?

The units can be powered by four “C” cell alkaline batteries, a rechargeable NiMH battery pack, or a power cable connected to the machine battery.

Can these receivers be used on both dozers and excavators?

Yes, while the ACE feature is designed for excavators, the LR60 is highly effective for grading on dozers when set to the center on-grade mode.

Is the receiver durable enough for heavy civil engineering environments?

Both models are built with rugged aluminium cast housings and internal shock mounts to protect the electronics from the high vibrations of heavy machinery.

How is the laser receiver mounted to the machine?

The unit features heavy-duty stainless steel clamps that allow for quick and secure mounting to a round or square mast on the machine arm.
