CONSTRUCTION DETAILS
The lightweight working access and safety platform is designed to sit inside a construction area with the edges of the platform butting up to the walls on all four sides; the platform is 1metre square supported on 1800 mm long yellow UPVC legs made from 65mm square hollow box sections. Note also that bridging panels can be fixed on to the top surface so that various size spaces can be fitted out with the safety platform.

LEGS AND LOCKING PIN CONFIGURATION
The platform panels sit on head\foot\retainer (HFR), which fit over the box section legs, locking pins are pressed through the (HFR) to retain the legs and feet, a polymer cord is attached to the pins, this acts as a visual check for correct installation as the pins hang down if not installed. Pins are pressed through the (HFR) to retain the top panel. NOTE: The way in which the pins are configured at 90 deg to each other on the same panel.
