SGM - Travelling automatic cleaning for bar screens

The automatic cleaning for bar screens, SGM type, equipped with grab bucker, represents an advanced technical solution between the systems of automatic cleaning of bar screens installed in big channels, for water intake from sea, lakes, rivers and also large water treatment plants.
In particular, it is mainly composed of: 
- a supporting frame in steel, composed of a set of pillars supporting a sliding monorail; 
- a trolley, moving on the above mentioned monorail, equipped with four wheels mounted on bearings whose one motorized with gearbox. The electrical feeding of internal components of the trolley is assured by a festoon line with multipolar cable or, on demand, by an electrical cable reel. 
- an electric hoist, installed inside the trolley, that by means of two strong steel ropes wrapped up in one drum, bears the grab bracket during its run upward and downward the channel. The hoist is equipped with a self-braking gearbox, adjustable position detectors and electromechanical overload protection devices; 
- two double effect hydraulic ram pistons, made of stainless steel and high quality components, for bucket opening/closing. The pistons are fed by an hydraulic control unit mounted on board the trolley; 
- a grab bucket for screening material collection. The bucket is composed of a fixed rake scraping type made of strong plates having the same wheelbase of bars, always in contact with screen bars, dragging the screening material on channel bottom during its run downward and of upper rotating pliers, directly fed by the two pistons, harpooning and holding during its run upward the screening material previously deposited on channel bottom.
The SGM model is particularly flexible and efficient, because it can guarantee, in the meantime, the deep cleaning of bar screens, the transport of collected screening material and the discharge into dedicated areas, like isolated zones side channel.
In particular, the SGM trash rake can also follow winding trajectories or mixed paths both straight and curved, offering the possibility to clean also screens very far from each other and not placed alongside each other.
Its operation, both manual and completely automatic, can be also applied to single portions of the screens during the maintenance of the other ones or during the draining of channels.
