BULK DELIVERY TECHNICAL INFO
ROAD NETWORKS USED
BGC Cement operates three standard types of heavy vehicle combination for bulk cement deliveries. Like all heavy vehicles they are subject to the restricted access vehicle (RAV) networks depending on the vehicles length, size and axle grouping. Our standard networks used for delivery throughout Western Australia are:
We can also operate on the following networks for special projects and with prior arrangement:

Cam Fittings & Silo Compatibility
All BGC tankers and PODs operate on a standard 4″ cam-lock fitting. Hoses have standard female fittings on each end for connection to the pneumatic tanker and the silo. In cases where the silo operates a reversed-cam fitting by presenting a female inlet, cam-lock adapters are used to make the connection.
Tanker Discharge Location & Hose Safety
The discharge outlet on all BGC Cement tankers is located on the left hand side of the vehicle. This is important to know when planning traffic flow for your site deliveries. It is preferable and safer to always have the tanker outlet facing towards the silo inlet.
In the event that a high-pressure hose were to break free from the cam fitting, safety devices called ‘hose whips’ or ‘whip checks’ prevent the hose from whipping around. BGC pneumatic tanker operators use hose whips for all hose-to-cam fittings and hose-to-hose connections.
Tanker Discharge & Operating Pressures
BGC pneumatic tanker operators are all trained and VOC’d to operate the equipment in accordance with the tankers manufactured specifications.
To reduce or eliminate any dust while unloading, the tanker operator will adjust pressures to ensure the correct balance of product and air. For customers who have silos with specific pressure requirements, a dedicated work instruction will be developed and issued to all tanker operators attending that particular site. This is usually established during our site visit prior to first delivery.
Unloading times can be affected if using lower pressures, or if the inlet pipe is excessively long into the silo. Our trained operators will fine-tune the discharge process, ensuring maximum product flow versus excess air, which is the cause of dust. At the purging stage, more air is able to enter the pipes, so the operator will have started reducing pressure to eliminate the possibility of dust from the silo breather pipe. Dust can be avoided, providing the silo has clean and maintained dust collectors.
