CWS, a different way of dealing with the collection of waste
The garbage collection: an endemic problem
The overall economic development of the Western economies and large growth of the overall standard of living has also led to a series of negative consequences. And on negative aspects of the relationship 'economic development - environmental problems' the theme of the collection of the increasing quantities of trash produced by our cities and its final destination have been gradually increased in importance.
The quest for efficient solutions, with a limited environmental impact, and that they can fit in with the different customs of life of Western citizens has determined a continuous transformation of the modalities for the collection of garbage and its organization. In more recent times, with the ecological sensitivity of much citizens as well as the general health requirements grow, the problem of the treatment and final destination of the waste is in the order of the day.
In recent years to the problem of how to collect the trash and how remove it is adding the problem of moving and transport to their final destination, safely and with minimum cost, the same collected garbage at distances always higher. In the past was very common, for example, that a landfill is placed not more 5-10 km from the Centre of the city. Currently there are many cities that are planning to put landfill sites to more than 60 kilometres from the Centre of the city. The problem is not only in terms of absolute distance, but also in the time of transport.
The thrust that all European Governments have given to the selective collection, in the bed of the already remembered general ecological sensitivity, has identified new problems related to the management of selected garbage.
In this case, also in small towns, it is necessary to move out of different fractions of waste treatment plants. First of all, that there is always more resistance from the citizens to place these plants in places near the inhabited centres and, secondly, that, for economic reasons, it is preferable to place these facilities in the Centre of an area of influence that can serve profitably several nearby cities.
New possibilities of perfectly integrating the phase of the garbage collection with its transport to configure more complex but more profitable economically transport systems have been introduced in recent years. Systems that arrive to use not only the normal transport by road, but also transport with train and even boat, reaching, as found in some countries of Northern Europe, hundreds of miles away from the place of collection.
The OMB-CWS system
The CWS system is a set of machines and devices mounted on auto racks suitable for making flexible use of the latter integrating them into a logical system of collection and transportation of solid, recyclable waste material number. The common denominator of the CWS system is a detachable collector team, Luton on 3-axis autobastidores, equipped with a cargo hook called CWS-B2. Another core component of the system is the closed fundraising box called 'cws-Body' with a capacity of about 23 cubic meters, made of top quality steel sheets and composed by:
- Front opening of collection / filled, can be combined with the hopper unloading of the CWS-B2 collector.
- Anchors for the hydraulic lock to the fixed structure of the car frame.
- Rear gate for the discharge of waste with Board of sealing and locking system (the discharge of waste is produced by gravity prior lock box).
- Device of guillotine for automatic closure of the front opening (side press).
- The movement of the CWS-Body hook.
The CWS-Body is lifted and installed on the collector mono-operador of lateral load model CWS-B2, which, equipped with a lateral Coil turning (elevation group), can automatically empty containers of waste.
Once filled, the CWS-Body is replaced by one empty and the full can be transported to places of waste treatment. Transport is possible thanks to the 'hook-lift' team which can drag a special trailer in which other CWS-Body is placed. This team can, through the device itself to load, position and load the CWS-Body both from the ground and from the trailer.
The three phases in the collection with CWS
Phase 1: garbage collection
The CWS-Body takes a front opening for filling that fits perfectly into the hopper of load of the declared car through a device of guillotine lock automatically-operated from the same vehicle. The back door of the Body has a packing of sealing and a hydraulic system that, through a mechanism of quick Coupler, connects the hydraulic circuit of the vehicle: the discharge of waste is carried out turning the box.
Phase 2: loading / unloading
Once filled the box, it is possible to download it, mail the and replace it with another empty consenting, in such a way, that the truck continue carrying out the operations of collection without downtime. To be able to speed up operations for loading and unloading of the Fund, the vehicle as much as possible OMB CWS-B2 has mounted a so-called specific "SHF-Lift' device suitable to load and unload automatically truck swap of 23 cubic metres. The replacement of a Body does not require more than 4 or 5 minutes.
Phase 3: transport to the destination of the waste
At a subsequent stage, it is possible to take the funds deposited to the final waste treatment plants or landfill through a special vehicle type "hook lift". This vehicle consents, through its own device, download and upload the CWS-Body both from the ground and from the trailer. Loading and unloading operations can be carried out in 12 minutes approximately without the driver having to lose the vehículo-remolque.
