Semi-Gantry Crane

Brand: Henan Hengkun Crane Co., Ltd.
Applications: Workshops, warehouses, logistics centers, steel processing plants, and facilities requiring flexible lifting solutions with partial runway systems.

Product Overview

Our Semi-Gantry Crane combines the versatility of an overhead crane with the adaptability of a gantry system, featuring one leg supported on a runway rail and the other on a ground track or floor. Designed for space-constrained environments, it offers cost-effective material handling for medium-duty applications while minimizing structural modifications to existing buildings. Ideal for lifting capacities up to 50 tonnes, this crane excels in scenarios where full runway systems are impractical.

Key Features & Benefits

Space-Saving Design
- Single-leg rail support reduces infrastructure costs and simplifies installation.
- Compact structure maximizes horizontal and vertical workspace utilization.
High Flexibility
- Adjustable span and height to accommodate varying workshop layouts.
- Compatible with both indoor and outdoor operations (optional weatherproofing).
Energy Efficiency & Safety
- Variable frequency drives (VFD) ensure smooth acceleration/deceleration and energy savings (up to 25% less power consumption).
- Dual braking systems, overload protection, and emergency stop functions.
Durability & Low Maintenance
- Reinforced steel construction with hot-dip galvanizing or epoxy coatings (ISO 12944 C4 standard).
- Premium components (ABB/Siemens motors, SKF bearings) for extended service life.
