5.2.3 Configurations and operating mode
General Principle
GEO D10 / GEO SUB rigging system operates in compression mode: pull-back force applied between
the extreme bottom cabinet and the top bumper set angles between cabinets. When the array is lifted
into position all cabinets are at 0° (1) and it is only when the pull-up force is applied that the correct
angles are obtained (2). Bumper angle is then set by adjusting front and rear motors (3).
(1) LIFTING CLUSTER VERTICALLY (2) APPLYING COMPRESSION (3) ADJUSTING BUMPER ANGLE
In case GeoD10 cluster is flown from one rigging point (8 GEO D maximum, no GEO SUB allowed),
array is lifted with all cabinets at 0°. Pull-back force and bumper angle are then set with the Chain Lever
Hoist LEVA750. Please refer to sections below for detailed description.
