Rayco-Wylie i4301 RCI (Rated Capacity Indicator) System

Crane Indicator | RCI (Rated Capacity Indicator) System

Scale and Control Inc. offers the Rayco-Wylie i4301 Crane Indicator / 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 Crane Indicator | 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 also 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.
