Introduction
The GKD rated capacity indicator is an integrated road-rail rated capacity indicator system.
The system incorporates state of the art sensing and processing to provide audible and visual warning
plus machine control signals. This manual applies to GKD 3RCI+ systems version 9 only.
Informa�on contained in this instruction guide may not apply to previous versions.
This manual covers both 3RCI+ and 3RCI+ SpaceGuard variants of the system.
Warning
During normal opera�on the SWL (Rated Capacity) of a crane should not be exceeded. Therefore the
warning of overload should not be used as a normal opera�ng facility. It should be noted that certain
statutory requirements do not permit the safe working load to be exceeded except for the purpose of
tes�ng.
THIS RCI IS NOT SUITABLE FOR USE IN EXPLOSIVE ATMOSPHERES. ADJUSTMENT BY UNAUTHORISED
PERSONS WILL INVALIDATE ANY WARRANTY OR CERTIFICATION SUPPLIED. IF A PROBLEM ARISES
WHICH CANNOT BE RECTIFIED USING THESE INSTRUCTIONS, AUTHORISED SERVICE SHOULD BE
SOUGHT.
THIS DEVICE IS CERTIFIED TO MEET CURRENT UK & EC SAFETY REGULATIONS FOR EXCAVATORS USED
AS CRANES, AND IS COMPLIANT WITH RSSB STANDARD RIS-1530-PLT Issue 4.
3RCI+ SPACEGUARD IS CERTIFIED TO MEET THE CONDITIONS OF NETWORK RAIL REMIT MLD-R003 FOR
MOVEMENT LIMITING DEVICES WORKING ADJACENT LINE OPEN AND UNDER LIVE OVERHEAD CABLES,
PROVIDED IT HAS BEEN INSTALLED AND CONFIGURED IN ACCORDANCE WITH GKD INSTALLATION AND
CALIBRATION INSTRUCTIONS, IS USED IN ACCORDANCE WITH THE GKD OPERATING INSTRUCTIONS,
AND IS SUBJECT TO REGULAR TESTS TO ENSURE CORRECT OPERATION.
Backwards Stability
The working condi�ons of these machines mean it is possible under extreme situa�ons of cant and
gradient to tip the machine over backwards. In particular this may occur with high boom angles when
working up the gradient or with the counterweight down the cant. The GKD indicator automa�cally
monitors for backward stability when working on rails. The system has two levels of protec�on, 50 mm
and 150 mm cant. In the event of a backward stability warning being shown, do not remove any load
from the machine until it has been returned to a safe posi�on.
In-gauge indicator
The indicator includes an aid to drivers with an in-gauge warning. This is designed as a guide only and will
not take into account any a�achments or modifica�ons made to the machine. The operator must check
the machine suitability to travel particularly for height. No liability is accepted for any damage or
consequen�al loss caused by travelling this machine with or without the in-gauge indicator.
SpaceGuard
3RCI+ SpaceGuard systems can be cer�fied to work under OLE and system 1,2 and 3 ALO conditions.
It is the responsibility of the operator to ensure that the system is fully operational and that the
dimensions of any load or attachment is taken into account when se�ing limits. In opera�on, the slew
speed of the machine should never exceed 2 meters per second measured at the bucket pin when a slew
limit or virtual wall is set.
