Single Girder Gantry Crane

Brand: Henan Hengkun Crane Co., Ltd.
Applications: Outdoor material handling, construction sites, shipping yards, warehouses, steel yards, and logistics hubs requiring flexible, rail-free lifting solutions.

Product Overview

Our Single Girder Gantry Crane is engineered for versatile outdoor and indoor operations, offering a lightweight yet robust design for efficient load handling. With a simplified structure and modular components, it delivers cost-effective performance while minimizing installation time and infrastructure requirements. Ideal for lifting capacities up to 20 tonnes, this crane excels in environments where fixed runway systems are impractical.

Key Features & Benefits

Lightweight & Compact Design
- Single box girder construction reduces self-weight and wheel pressure, lowering foundation costs.
- Low headroom design maximizes vertical workspace utilization.
High Efficiency & Flexibility
- Rail-free operation adapts to uneven terrain or temporary worksites.
- Smooth variable frequency drive (VFD) ensures precise load positioning.
Durability & Low Maintenance
- Hot-dip galvanized or epoxy-coated steel resists corrosion in harsh environments.
- Premium-grade components (ABB/Siemens motors, SKF bearings) extend service life.
Energy-Saving & Safe Operation
- Regenerative braking system recovers energy, reducing power consumption by 20–25%.
- Dual braking mechanisms, overload protection, and emergency stop functions.
