A quick and simple system for effective de-polluting of End of Life Vehicles(ELV).
The Vehicle De-pollution Unit (VDU) provides a packaged solution for removing
all the required fluids from an ELV and pumping them to a fluid storage facility
The unit integrates a 3T scissor lift to access the underside of the vehicle, although
it can be used with a static frame.
Vehicles are loaded sideways onto the scissor lift by a fork lift truck, the adjustable
chocks on top of the lift bed support the vehicle by its sills whilst allowing the forks to
be easily withdrawn and re-introduced after the de-pollution activity is complete.
Whilst the lift is at low level the wheels are removed and the engine compartment
reservoirs emptied.
All the extraction probes for the engine compartment activity are mounted on the elbow of the right-hand arm adjacent to where the engine compartment sits.
The probes are connected to the VDU by high quality coil hoses which are guaranteed not to kink for ease of use.
The operator can drain the reservoirs with the minimum of physical movement ensuring maximum time efficiency.

Each fluid has its own pumping circuit which both extracts the fluid and then
pumps it away to a storage facility. Operation of the pump is made clear by using
a mixture of colours ,graphics and text adjacent to each pump valve. |
Once the engine compartment reservoirs are empty the vehicle is raised to a height appropriate for the reach of the operator - shorter workers will require the vehicle lower than taller people, a feature not possible with fixed platform installations.
Once at the required height the lift is mechanically locked in position eliminating any danger of a hydraulic failure causing the vehicle to change position when the operator is underneath.

Sump and gearbox oil are drained into the two large funnels mounted on the right-hand arm. Each funnel swings independently to ensure both can be drained at the same time. A similar funnel is mounted at the back for the rear differential. The radiator is drained by introducing a hollow spike into the lower radiator hose. The spike is mounted on the end of the arm with the funnels
to again, minimise operator movement. |
Brake cylinders are emptied by connecting onto the front bleed nipples.
| On cars with under body fuel tanks, fuel is extracted by piercing the tank with our unique fuel extraction tool. The tool seals to the bottom of fuel tank preventing fluid or vapours escaping during the extraction process. The fuel drains into the inspection glass allowing the operator to grade the quality of the fuel. Dirty or contaminated fuel can be sent to a separate tank from clean fuels. The system has several safe guards to ensure the operator distinguishes between petrol or diesel. The system has the option of a 5 micron fuel filter which can remove water from the fuel should the operator make a mistake.
For vehicles where it is either not possible or desirable to puncture the tank the system
includes a siphon pipe for extracting fuel out of the filler pipe. |

The VDU incorporates an option of a shock absorber draining tool, which punctures the shock absorber and drains the fluid through a sealed hole.
|
Once de-pollution is complete the car is lowered and removed by fork lift truck.
Typical processing times are less than 15 minutes per vehicle.
The VDU provides the most modern approach to vehicle de-pollution.
The system is modular in that any number of VDU bays can be piped upto a single fluid storage facility.
Requires 40cfm of compressed air at 7 bar, and a three phase power supply.
(Single phase machine available)
