Core Features & Benefits
Powerful Oblique Pointed Rake Teeth: Specially crafted "oblique pointed" shape welded as a single unit with the horizontal axis provides immense grabbing power for large, heavy underwater debris.
Ultra-Safe Double Overload Protection: Comprehensive safety system with mechanical shear pin and overcurrent protection prevents equipment damage from unexpected underwater overloads.
Smooth & Low-Noise Direct Drive: Cycloidal pinwheel or helical gear reducer motor ensures compact structure with remarkably smooth, quiet operation.
Integral Frame & Easy Monitoring: One-piece chassis structure simplifies installation and reduces maintenance, with support for local and remote operational status monitoring.
Frequently Asked Questions
What environments is this grille cleaner best suited for?
Primarily designed for high-flow water conservancy environments, including large-capacity drainage pump station networks and water inlets of massive water conservancy pump stations, specifically for intercepting large chunks of solid floating debris.
Will the rake teeth bend or fail when encountering extremely heavy or large garbage?
No. The specialized "oblique pointed" design welded as a solid, integral piece with the horizontal axis and 3000 N/m load capacity ensures heavy reinforcement for scooping large, heavy debris with ease.
If a giant underwater obstacle jams the machine, will the motor burn out?
Absolutely not. The dual safety defense system with mechanical shear pin and overcurrent protection engages immediately during accidental overloads, eliminating risk of motor burnout or mechanical damage.
