Floodgate Gantry Crane

Brand: Henan Hengkun Crane Co., Ltd.
Applications: Dam maintenance, flood control systems, hydropower stations, sluice gates, and water conservancy projects requiring heavy-duty, corrosion-resistant lifting solutions for gate installation, removal, and emergency operations.

Product Overview

Our Floodgate Gantry Crane is specifically engineered for harsh aquatic environments, combining robust construction, anti-corrosion technology, and precise control to handle massive floodgates, sluice gates, and hydraulic structures. Designed for capacities up to 500 tonnes, this crane ensures reliability in extreme weather and high-moisture conditions, critical for flood prevention and water management infrastructure.

Key Features & Benefits

Corrosion-Resistant Design
- Marine-grade coatings (ISO 12944 C5-M) and stainless steel components resist saltwater, humidity, and chemical exposure.
- IP68-rated motors and waterproof electrical systems for submerged or splash zones.
High Stability & Precision
- Reinforced double girder structure (FEM 4m class) minimizes deflection during gate alignment.
- Laser-guided positioning (±3mm accuracy) and anti-sway systems for safe load placement.
Adaptability to Harsh Conditions
- Storm-proof design withstands winds up to Beaufort Scale 12 and temperatures from -30°C to +60°C.
- Customizable leg heights for uneven terrain or elevated platforms near water bodies.
Energy Efficiency & Safety
- Regenerative braking and variable frequency drives (VFD) reduce energy consumption by 25–30%.
- Dual fail-safe brakes, overload protection, and emergency power backup.
Modular Assembly
- Prefabricated components enable rapid on-site installation in remote or flood-prone areas.
