Preparing and Mounting the Signal Head
The signal will arrive from the factory on a standard pallet where it should remain
until ready to commence the installation onto the prepared base.
Remove all packaging materials and dispose of in accordance with current
procedures and retain any paperwork etc as required.
The mounting nuts and bolts which attached the head to the pallet are transit
fixings only and shall not be used to mount the signal onto the base
Having taken into account the gross weight marked on the signal head and where
necessary removed the module(s) to reduce this weight, an onsite risk assessment
should be undertaken and a method of lifting the head into place shall be
determined. Two removable lifting rings are fitted to assist in mechanical lifting.
Once in the required position, the CLS LITE is secured to the base platform using
suitable mounting hardware. Ensure the Lower Backboard extension is fitted in its
operational position as detailed below.
Backboard Arrangement
The signals are required to display a uniform backboard of at least 300mm from the
centre of the lit aspect and the following procedure is applicable to both mounting
arrangements. To prevent damage to the lower portion of backboard during transit a
removable section is fitted in a stowed position to enable the signal head to be
bolted securely to its pallet. As part of the installation, this extension piece must be
moved into its operational position below the aperture once it has been removed
from the pallet.
