Bulk Container System.
The Bulk container system was introduced to deal with refuse
from flats, hospitals, hotels and other similar places in the district.
Some of the main advantages are as follow:—
1. Improved storage.
2. The containers are emptied hydraulically, and the operation is dustless.
3. The containers cannot be interfered with by dogs or cats.
4. Where the volume of refuse is substantial it does away with the need
for a large number of bins, which can look untidy and, take up a lot
of room.
Description of Containers.
Containers of up to cubic yards capacity 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.
Containers arc removed from chambers or other loading
positions (where they stand on side sills) by a simple form of Jack
Truck, by which they are lifted about 2" and transported to the
rear of the vehicle adjacent to the lifting hooks. The safety
catches are lifted and the container pushed against the lifting cradle
when the catches are dropped over the container handle, after
which no further action by the operator is necessary. The containers
are lifted automatically from the truck by the forward tipping
action of the body of the vehicle, and 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 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.
