Some traders are finding the bulk container system indispensable
and have 2 and 3 emptyings weekly. Two firms have, in fact,
daily emptyings.
During the year this system was introduced on the A.20 in
order to handle the large amount of refuse being dumped on this
trunk road.
Description of Containers.
The containers are of 1¼ cubic yards capacity of 16 s.w.g.
steel construction stiffened with angle and flat section bands, and
carry the lifting bar for attachment to the vehicle. The whole
being galvanised after welding.
Dimensions, 4' 3" high X 3' diameter. Circular type, or
alternatively with flat sides 2' 6" wide to suit narrow dust chambers.
They are emptied on site into an SD Refuse Collection vehicle by
an extremely simple method which does not involve any additional
hydraulic gear or controls.
There are 170 in the district at present in use.
For emptying, the containers are hitched to a gig at the rear
of the vehicle and are lifted automatically by the forward tipping
action of the body of the vehicle. As the body lifts the container
is tipped through a dustless sealed aperture in the rear door of the
body. The refuse from each container has the full available depth
of the body into which it can fall, this provides a substantial degree
of consolidation of refuse in the body.
The total time for discharging each container into the vehicle
is less than one minute. Owing to the popularity of the container
system a second S. and D. vehicle is now in commission adapted
for this work. Both vehicles now in use are fitted with Powerpress
patents which is a device for compressing the load so as to obtain
maximum pay load before journeying to the refuse disposal site.
Discharge of the vehicle load is by rear tipping, the rear door
opening automatically as in The standard Fore and Aft Tipping
vehicle.
Prevention of Noise.
A new type of bin is now on the market fitted with rubber lid
and rubber base. This type of bin is an attempt to reduce noise
and it is hoped these will find favour with the public.
Plastic bins are also coming to the fore. Unfortunately, they
are flimsy in construction, too easily damaged by rough handling
and ruined by hot ashes.
