Introduction
The electro-hydraulic self-moving screen machines are the premier commercial solution for efficiently clearing small suspended debris such as leaves, branches, cans, and sticks from water treatment channels. Engineered for automatic and reliable continuous operation, these systems maximize debris extraction efficiency while minimizing routine manual intervention on-site. Their robust structural design combined with an integrated hydraulic power pack ensures continuous uptime and exceptional longevity in demanding environments. Complete technical configurations and dimensional charts are available for review within the downloadable catalog.
Key Features
Automatic electro-hydraulic power pack operation, continuous sweep functionality for small suspended elements, high-resistance stainless steel chain and sprocket assembly, internal self-lubricating long-life composite bearing, modular grid elements designed for quick disassembly, rapid system disconnection and removal from the water channel, dedicated removable comb for deep grid cleaning, integrated electric control panel with precise speed regulation, advanced torque control with automatic chain rotation reversal for complete overload protection

Applications and Benefits
- Rectangular shape channels: Seamless structural integration and simplified installation inside existing channels;
- Waste water treatment without bulky objects: High-efficiency continuous removal of small suspended matter;
- Preventive maintenance routines: Direct access to internal components without the need to extract the machine;
- Torque regulation system: Complete prevention of structural damage and mechanical blockages via automated reverse rotation
Why Choose Our Products
Di Nicola manufactures machines for the cleaning of the channels with hydraulic piston with fixed machines for the cleaning of the grid or self-moving for the cleaning of grids of great extent by means of a timed cycle. The raker hydraulic Di Nicola consists of a support structure, a filtering screen, a rake for the screen cleaning, a rake cleaning device, a double acting hydraulic cylinder with one or more runs for the upward and downward motion of the moving unit, a second hydraulic cylinder for the rake traverse motion, an hydraulic unit and a control panel.This particular construction allows to fully reproduce the movement of a manual cleaning and evacuation of the debris onto a conveyor belt for discharging in appropriate containers. The machines for the cleaning of vertical hydraulic are installed on medium and large systems purification of waste water in civil or industrial, of irrigation channels or of the feed channels of dams or hydroelectric plants. Di Nicola follows the customers in all phases of installation creating a 3D mapping of the existing masonry, the masonry of editing, the installation sequence, allowing the installation company to operate in total autonomy, while ensuring the installation and supervision the commissioning. The raker hydraulic Di Nicola compliant to European machines are therefore provided with CE marking and manuals for use and maintenance over the documentation for the stand-alone installation.
