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 vehicle.
When the body is again lowered, the container returns to the
waiting Jack Truck and is automatically disconnected from the
vehicle and can be immediately returned to the loading site.
The total time for discharging each container into the vehicle
is less than one minute from the arrival of the container on the truck
to departure for repositioning on the loading site.
Bulk Loading Vehicle.
This consists of a modified SD Fore and Aft Tipping Refuse
Collector of 16/18 cubic yards capacity, which is fitted with a special
rear door carrying the necessary hooks for container attachment
and automatic safety locking gear. The upper part of the door
carries an aperture through which the mouth of the container enters
as the body lifts, this being dust proofed by the use of simple
double doors and a ring of rubber flaps. This arrangement forms
a fully effective dust screen and seals the entry of the container
before refuse commences to fall.
The upper portion of the door is hinged and spring loaded,
which can be lifted without effort and locked in an open position to
present a standard loading rave and fall opening for use when
discharging ordinary household bins at normal team loading rate
from ground level.
Discharge of the loading is by rear tipping, the rear door
opening automatically as in the standard Fore and Aft Tipping
vehicle.
Containers.
The containers are of 1 1/4 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 × 3' diameter. Circular type, or
alternatively with flat sides 2' 6" wide to suit narrow dust chambers,
and are adapted to stand on concrete sills 24 1/2" to 25" apart × 8 1/2" to
9" high.
Prevention of Noise.
A new type of bin is now on the market fitted with rubber lid
and rubber base. This 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
easily damaged, particularly by hot ashes."
