Rayco-Wylie i4301 RCI (Rated Capacity Indicator) System

RCI (Rated Capacity Indicator) System

Scale and Control Inc. offers the Rayco-Wylie i4301 RCI (Rated Capacity Indicator) system, ideal for calculating the load weight value by reading the strain on the crane's wire rope. This can be done through the use of a line tensiometer (linerider) on the wire rope to measure load weight, and a cable reel with angle sensor to measure boom radius. These values are then viewed on the i4301 Display. The i4301 can also function as a Load Moment Indicator.

Rayco-Wylie I4301 RCI System

  • System can be purchased as either an LMI or as an RCI
  • Load charts can be programmed into the display
  • The display has a built-in processor, reducing the number of components to be installed in the crane cab
  • Can monitor A2B (Anti-Two-Block) and other options
  • The i4301 4.3” Color Graphical Display provides the operator with best in class visibility of the display data when wearing polarized sunglasses
  • Data logging is available via download to USB
  • The i4301 is an ideal cost solution for applications where system customizations are not required. Designed for hydraulic and lattice boom applications
  • The display is IP67 rated, with a temperature range from -4°F to 158°F, an optional extended range display is available from -40°F to 158°F
  • LMI solutions are supplied with two pressure transducers to read the lift cylinder pressure
  • Line riding tensiometers, load pins and dead-end load cells are available for load sensing on RCI applications
  • Various cable reel sizes are available to suit your hydraulic crane type, with integrated angle sensor for monitoring boom length and radius. Available for both LMI & RCI
  • Angle sensor for lattice boom applications
​* Due to specific configurations needed depending on application, contact us for pricing and info on a system to best suit your needs

RCI (Rated Capacity Indicator) System
Rated Capacity Indicator - RCI
On a Rated Capacity Indicator, the load weight value is calculated by reading the strain on the wire rope. This is done by using a load pin in a sheave, a running line tensiometer (linerider) or a dead-end load cell installed at the becket end. A digital load chart is also available to show load capacity.

Calibration is simpler on an RCI as it removes the step of empty/loaded boom weight calibration for all boom configurations, as seen in an LMI. Calibration is done to train the load sensing device as to the strain on the wire rope. A cable reel with angle sensor is used as it is on the LMI to calculate radius.  

On a lattice boom crane, the RCI installation is much simpler and less costly from a calibration perspective as compared to a load moment system. A lattice boom RCI uses a strain gauge load sensor and an angle sensor for radius calibration.
