Operational Requirements that are essential to be incorporated into the design and manufacture of the prototype MMRCV
The vehicle is required to provide at least the same efficiency in a domestic and commercial refuse collection function within London Borough’s that can be achieved by using a conventional rear loading refuse collection vehicle. (The London Borough of Hackney is to be used as the model). Put simply, there must not be any reduction in efficiency with the prototype Multi-Modal Refuse Collection Vehicle over a
conventional RCV that is currently used by the London Borough of Hackney in their waste collection operation.
The prototype MMRCV must be capable of carrying a minimum payload of 10,000kg whilst not exceeding any design or plated axle weights or plated gross vehicle weight during any time of the waste collection operation.
The cab must be a low entry cab with a low floor height and a minimum of 3 crew seats in addition to the driver’s seat.
The bin lifting device must:
be fitted at the rear of the vehicle and attached to the compactor
be capable of lifting and efficiently discharging the waste into the compactor from:
wheeled bins, euro bins and paladin bins
retain an ‘open back’ and ‘low rave height’ functionality into the compactor for the ability of collecting black bags
The compactor must be fitted at the rear of the vehicle and the waste collection function is performed at the rear of the vehicle ‘rear loading’.
The compactor must be attached to the chassis with the ability to pivot at the point of attachment to the chassis to allow for the detachment of the compactor from the container and providing sufficient clearance to allow the container to be removed from the chassis.
The containers must be constructed so that it is capable of being detached and removed from the MMRCV (with a full and empty load) horizontally or vertically from either side by means of a gantry crane and forklift truck. The containers must also be constructed so that it is capable of being loaded, unloaded and tipped by using a hook loader vehicle.
The containers must be full sealed prior to the detachment of the compactor and remain sealed during storage and transportation until the point when the waste is discharged. There must not be any spillage (solid or fluid) during the operation of
57
detaching the compactor, removing the containers from the vehicle, storing the containers, transporting the containers and when attaching the containers to a hook loading vehicle.
The containers must be constructed to allow for an efficient waste discharge operation by means of tipping from a hook loader vehicle. This will require the containers to be fully opened at one end and the sides of the containers to be tapered to assist in the discharging of the compacted waste.

Bin Lifting device
Must be fitted at the rear of the vehicle and attached to the compactor
Must be capable of lifting and efficiently discharging of the waste into the compactor from: wheeled bins, euro bins and paladin bins
Must retain an ‘open back’ and ‘low rave height’ functionality into the compactor for the ability of collecting black bags
Section 2: The following will require either (a) specific design and manufacture for the prototype MMRCV (b) modification from designs and manufacturing currently employed that can be used in the manufacture of the prototype MMRCV
Containers
Three identical containers are to be designed, manufactured and supplied.
The container to be manufactured to DIN/CHEM standards.
Dimensions: Length: 5,000mm, Width: 2,300mm, Height: 2,500mm.
The container is to be rectangular in shape and of steel construction.
The container must be capable of being fully sealed from any waste spillage (solid and fluid) before the compactor is removed and remain sealed until the point of the required waste discharge.
Should be made to allow for transporting a minimum of 2 containers at the same time by road on a skeletal trailer or drawbar trailer.
The container is to be constructed so that it can be moved by means of a gantry crane, fork lift, and hook loader.
A waste ejection system will not be incorporated into the design of the container as the waste will be ejected through a ‘tipping’ operation.
The container is to be ‘tapered’ to allow for efficient tipping discharge.
The container is to have a fully open end during the waste discharge tipping operation.
The container is to be fitted with a self powered tracking device.
The container should be constructed to meet the above requirements but at a minimum cost of manufacture and supply.
59
Compactor/Packer
The compactor is to be mounted at the rear of the vehicle with the compressing function from the rear.
Waste is to be compressed into the container using the conventional compaction plate method.
Sensing devices are to be fitted that provide an audible warning and/or automatic shut down when either the container is full or the maximum weight has been achieved.
Demounting operation
The container is to be sealed before the separation of the compactor
The compactor must be separated from the container by pivoting the compactor on the chassis to allow for sufficient clearance between the container and compactor for the container to be removed vertically or sideways horizontally from the chassis. It is essential that this operation is performed without there being any risk of spillage (fluid or solid).
The container needs to be fitted and locked to the chassis by a method that provides a quick release and attachment but will also satisfy all health and safety
requirements.
A full or empty container needs to be removed and refitted to the vehicle in as simple and quick an operation as is possible. The whole operation of container removal and refitting to be performed in no more than 6 minutes by one operator.
Devices need to be fitted to the vehicle that protect the cab, chassis and compactor from any risk of impact damage during the demounting and remounting operation.
Compactor/Container Interface
The interface must be fully sealed when performing the waste collection operation.
The container must be fully sealed before separation of the compactor/container takes effect.
There must not be any spillage of waste (solid or fluid) during the separation of the compactor/container.
There must be an adequate locking device between the compactor and container to ensure no risk of separation during the waste collection operation.
The compactor/container interface should be kept as simple as possible, easy and quick to unlock and perform the operation of separating the compactor from the container.

General Comments
As many standard parts that are in current production should be used in constructing the vehicle.
The vehicle is to meet all current legislation applicable to the vehicle and its use.
The vehicle is to be tested and approved by VOSA and the HSE before it is accepted and made operational.
