Boom Angle:  RDI Digital LCD Boom Angle Indicator

All cranes, derricks and certain lift equipment require some form of boom angle indication. Boom angle indicators must be visually readable by the operator.

Rieker Boom Angle and Tilt / Level Indicators Comply with Current OSHA Standard 1926.550

  • Angle range -10 to +90
  • Backlit LCD Display Resolution of 0.1
  • Adjustable LED trip settings
  • 8-30VDC non-regulated supply
  • Military Style Amphenol Circular Connectors for interface cable

Description

Rieker's Digital Boom Angle Indicator Remote Inclinometer Package (model RDSR3-BA-09) is an extension of the RDI series of digital inclinometers.

Like the 4120, our electronic boom angle indicator is sealed in a rugged case that protects the sensor components from harsh environments. The RDSR3 is supplied as a calibrated set featuring an environmentally sealed measurement sensor package and a separate LCD display box (connected by an interface available in various lengths). All of the standard RDI features have been incorporated into this remote sensing package, modified specifically to comply with OSHA and other safety regulatory agencies specifications for Boom Angle Indicators.

The display model comes standard with green, yellow, and red LED lights (with adjustable trip setting) provide the operator a bright fast visual warning of safe and unsafe operating conditions. The green light indicates safe operating zone, yellow as the early warning, and red as the danger zone. An optional audible alarm model is also available - the red LED on the front panel display is tied directly to the buzzer.

The RDSR3-BA-09 comes standard with Relative Zero and Min/Max Angle functions. The Relative Zero allows the operator to temporarily zero the digital readout to obtain relative slope changes. The Min/Max function provides the smallest and largest angle since the last reset.

If you have an application that requires custom specifications, please contact us today with your requirements. One of our engineers will be happy to speak with you.

 

Please note:  A boom angle indicator is a quick reference for the operator to know what angle the boom is at. The capacities that are listed on the crane load charts are also based on and vary with the boom angle of the crane. However, do NOT rely on the boom angle indicator for radius accuracy especially when the lift exceeds 75 percent of the rated capacity. Use the radius measurement to determine the capacity of the crane from the load charts and to avoid any possibility of error.
