YHJ Intelligent Hoist Gate Operator
The YHJ Intelligent Hoist Gate Operator is a highly integrated and modularized device developed through continuous research, innovation, and testing based on traditional screw hoist designs. It features a modular architecture that includes the following components: lifting module, transmission module, safety module, gate opening measurement module, control module, anti-theft and anti-vandalism module, power supply module, water measurement module, and expansion modules. The modules are easy to assemble and disassemble, and the system is user-friendly.
Key Features:
High-precision water control and measurement
Long-term operation in field environments without power supply
Sixfold protection: waterproof, moisture-proof, insect-proof, temperature-resistant (both high and low), theft-proof, and vandal-resistant
Manual control in case of malfunction
Data acquisition and transmission capabilities
Real-time gate status monitoring
The measurement and control system is especially suitable for retrofitting existing gate systems. Without replacing original equipment, it can realize flow measurement, gate position control, remote operation, and equipment monitoring simply by integrating this system.
Advantages:
Powered by a 24V DC motor, enabling off-grid field operations.
Equipped with high-quality solar panels and high-capacity batteries, supporting continuous operation for up to 7 days during overcast or rainy conditions.
Anti-theft housing: one-piece cast housing made of ductile iron with high strength and elasticity, providing robust anti-vandal protection.
Special anti-theft screws ensure operational safety and prevent unauthorized access.
Screw nuts are made of tin bronze, ensuring durability and corrosion resistance.
Lead screws are precision-manufactured from #45 steel.
Transmission mechanism adopts a bevel gear and worm gear combination, offering high gear ratios, high rated output torque, and compact size.
Bevel gears are made of 20CrMnTi, a high-performance alloy steel.
Worm gears are made from zinc alloy, which offers low friction and improved transmission efficiency.
Integrated load sensors for accurate force monitoring.
Includes an absolute encoder for precise gate position tracking.
Fitted with mechanical limiters for enhanced safety.
Equipped with a manual crank system for emergency operation in case of power loss.
Integrated with Haiwang measurement and control system, supporting water level measurement, local and remote operation, with gate position accuracy of less than 1mm.
High lifting capacity: up to 20 tons, capable of operating gates as large as 5m x 3m.
