This large aspect bollard is the larger relative of the 'Springbak' bollard, also made by Haldo. The bollard had been stored in the former Derby City Council Street Lighting depot on Stores Road, but had never been used; indeed, it entered the collection whilst still encased in its protective outer plastic cover.
The bollard really is as large as it looks in this photograph! The SL 160 code is written in several places on the plastic covering, so I'm guessing that it is the part code for this type of bollard. Bolted to the base of this bollard is a small box containing the cable and a piece of wood designed to support a cutout. Although the bollard bears a resemblance to the Springbak, the Shearbak does not have springs in the base and so if it is hit by a speeding vehicle, the shell is designed to break away to minimise human injury.
On the top, the code can also be seen, but also '2 × 8 W' and '2 × 13 W' have been written. This is the only way that I can guess what tubes the bollard takes without cutting the plastic cover.
Looking at the back of the bollard now, and yet more codes can be seen.
This is a close-up of the top code.
Due to the bollard's size, I left it outside for some months before space became available indoors. Luckily the protective cover kept it reasonably clean, however there were several holes in it near the base, which had marked the shell, but hopefully these will just wipe off.
The plastic was a little grubby, but the stains will wipe off.
The bollard had to be tipped on its side for me to remove the shell due to the height. Once the shell had been removed, the construction of the spine became clear:
The bollard did indeed take a couple of 8 W and 13 W tubes - the latter light the roundel, and the former light the yellow cylinder area, near the base. The top section is not meant to lean to one side, but one of the screws holding it in place was loose. This is a complaint that I suffer on a day-to-day basis, but the difference is that the one on the bollard can be easily sorted...
A wiring diagram is shown on the spine; perhaps to aid engineers when changing the ballasts or starters.
The spine has three 13 W ballasts fitted - two for the individual lamps, and one to power the two 8 W lamps.
Despite the large size, the shell is still one complete piece that is secured by a tri-head bolt around the back.
Tubes were fitted, and then I plugged a lead into the socket under the base, and powered up.
The shell was then refitted, but even with it in place, the shape of the 13 W lamps could still be seen!
