Facia framework with pole plate - incorporates adjustable support caps pressed against roof by hydraulic rams with fault shield hinged to rear end of facia

摘要

The support caps (22) are height adjustable through a pivot bearing (26) on the facia and are pressed against the roof (21) by hydraulic rams (27) and are located on either side of the opening (17). The facia (3) has an opening for the support caps. On both sides of the opening in the facia are slots which locate the support caps. The caps are formed of a plate (23) which grips into the slots and is positioned under the slots, in the bearing of the facia. ADVANTAGE - The framework is reliably stabilised against tilting.
