Our cleaning facility for the external cleaning of the trucks, trailers and containers is exposed to extreme conditions every day such as heavy pressure, moisture, cleaning agents and a high level of mechanical loads on both the machine and floor. After 16 years of faithful service, it really did need replacing. Much has changed in those 16 years and in combination with less towing vehicles and more tank containers, which had an impact on the specifications of the new cleaning facility.
We closely examined current shortcomings and future preferences to determine the optimal specification. In addition to legislation and regulations, two principles had the highest priority, namely, staff working conditions and the sustainability of the entire cleaning facility. A system was developed in close partnership with different suppliers that is tailor-made for Nijman/Zeetank.
Staff working conditions
Cleaning tank containers is mainly manual work. In order to make this work lighter, it is best not to work from a floor height, but at an average standing height of one metre. The cleaning platforms have been secured to the cleaning portal because the cleaning building is too narrow for standalone platforms. The platforms can be folded away and are adjustable with regard to height.
To guarantee safety, the platform has a safety railing and is easily height adjustable.
Even though Nijman/Zeetank constantly looks for the friendliest
of cleaning agents that burden the environment the least, the Company wants to expose staff as little as possible to anything that should not really be in the air we breathe. An active ventilation and exhaust system discharges all fumes and guarantees a pleasant working environment. An automatic mixing system ensures the correct metering of the cleaning agents so that you always work with a constant and safe concentration.
The operation of the portal through a touch screen suspended in the “dry room” is easy to use. In the unlikely event that something goes wrong, six emergency stops ensure that the process can be stopped at any time.
A new liquid-tight and anti-slip floor was laid to protect the soil but also the staff. The grating can be loaded for up to 3,400 kg/mm2 so that all work equipment can drive through the cleaning facility without the risk of ending up in the guttering.
Everything in the building is made of stainless steel to ensure moisture and cleaning agents cannot negatively affect the system, pipework and all other issues. This material will extend the service life of the system. It was the first time that the supplier delivered a cleaning system that was only made of stainless steel. In addition to the system, all steel structural parts, the grating, cable trays and wall supports are made of stainless steel.
The motors used have been selected based on the performance standards that will come into effect soon, so that it is future proof. They ensure that the power consumption is low which means that the total fused power is reduced. All lighting is of the LED type contained in a watertight stainless steel housing.
Side brushes were developed especially for Nijman/Zeetank that have bearing races both on the top and bottom side. The side brushes run free when compared to standard car washes. When cleaning tank containers, the load with a single bearing race would become too high, which would lead to excessive wear.
The entire system works with soft water. This improves the cleaning, preventing limescale deposits and slowing down wear. The system also makes smart use of water through special nozzles that have an optimal operation with regard to pressure and water consumption.
