Lattice Gantry Crane

Brand: Henan Hengkun Crane Co., Ltd.
Applications: Shipyards, construction sites, steel mills, ports, power plants, and heavy industrial facilities requiring large-span, heavy-load lifting in outdoor or harsh environments.

Product Overview

Our Lattice Gantry Crane is engineered with a lightweight yet robust truss structure, combining high load-bearing capacity with cost-effective design. Ideal for lifting capacities up to 500 tonnes and spans exceeding 60 meters, this crane excels in applications demanding durability, stability, and adaptability. The open lattice framework reduces wind resistance and material costs while maintaining structural integrity, making it a preferred choice for large-scale outdoor projects.

Key Features & Benefits

High Strength & Lightweight Design
- Triangular lattice girders minimize self-weight while maximizing load capacity (FEM 3m–5m class).
- Modular assembly simplifies transportation and on-site installation.
Large-Span Capability
- Customizable spans up to 100 meters for wide-area material handling.
- Reinforced legs with adjustable bases for uneven terrain or rail-mounted configurations.
Durability in Harsh Conditions
- Hot-dip galvanized or epoxy-coated steel (ISO 12944 C5-M standard) resists corrosion, moisture, and UV damage.
- IP66-rated motors and enclosed electrical systems for extreme environments.
Energy Efficiency & Safety
- Variable frequency drives (VFD) ensure smooth operation and reduce energy consumption by 20–25%.
- Dual braking systems, overload protection, and anti-collision sensors.
Customizable Configurations
- Compatibility with hooks, grabs, magnets, or specialized lifting attachments.
- Optional automation: remote control, GPS positioning, or IoT-based diagnostics.
