Rated Capacity Indicator / Controller

7.1 Introduction

The PME200 RCI / RCC has been designed to meet European requirements for the pro-
vision of rated capacity indicators. PME200 ensures that the maximum lifting capacity
over the range of a machine working envelope can be utilised. The system will always
start up in Lifting Mode. See section 4 for operating advice when using construction plant
as a crane. The Lifting Mode feature can be used in conjunction with envelope monitor-
ing, see section 8. In this mode, the beacon (if fitted) will indicate that the Lifting Mode
functionality is active.

5. RCI / RCC indicators
1. Lift point radius is the horizontal distance in metres from the slew centre line to the
lifting point.
2. Current lifting duty in use.
3. Current lift point in use.
4. Safe Directional indicators. The triangles on both sides of each piece of equipment
and slew arrows indicate if it is safe GREEN, or unsafe RED to move the relevant
articulation and direction in that direction under overload envelope limits. A triangle
with a red border indicates that the articulation is limited by hydraulic capacity and
not by machine stability.
5. RCI / RCC - MEC indicators (see section 3)
6. Maximum Safe Working Load (SWL) for the current lifting point height and radius
combination. The value is given in metric tonnes.
7. SWL percentage bar graph indicating the percentage of the current load to the
maximum available safe working load.
8. Load on Hook (LOH) shows the current load in tonnes suspended from the current
lifting point.
The SWL as displayed assumes that the load is suspended directly below the
lifting point. The weight of the tool or tools, if fitted, (e.g. Bucket , quick hitch etc)
are accounted for in the SWL and LOH values if they were taken into consideration
when the system was calibrated. The bucket cylinder and control linkage is
assumed to be present.
