Double girder overhead cranes are the ideal solution for lifting heavy loads exceeding 50 tons or for applications requiring high work duty and extended coverage. With versatile main girder connection options, these cranes can be seamlessly integrated into both new and existing building structures. Their dual-girder design allows the hook to travel between the girders, achieving exceptionally high lifting heights. Each crane can be equipped with maintenance platforms positioned under the motors or along the full bridge span for easy servicing. Available in a wide range of spans, lifting heights, and customized speeds, double girder overhead cranes can also accommodate multiple hoisting trolleys or auxiliary hoists, ensuring maximum flexibility, performance, and efficiency for demanding operations.
Features
Smooth Starting and Braking: The workshop overhead crane adopts advanced motor and control technology, ensuring smooth acceleration and deceleration. This minimizes load swing, providing stable and precise lifting operations.
Low Noise and Spacious Cabin: The crane is equipped with a comfortable operator cabin featuring a wide field of view and sound insulation design. Low noise operation creates a safer and more pleasant working environment.
Easy Maintenance and Interchangeable Components: All key parts are designed for convenient inspection and maintenance. Standardized, high-quality components allow for excellent interchangeability, reducing downtime and maintenance costs.
Energy Saving and High Efficiency: Equipped with efficient motors and frequency conversion control, this workshop overhead crane achieves significant energy savings while maintaining strong lifting performance, reducing energy consumption and operating costs.

1. Design Production Drawings
The process starts with detailed engineering and 3D modeling of the 30 ton double girder overhead crane. Our design team ensures every drawing meets structural, performance, and safety standards while aligning with the customer’s specific lifting requirements.
2. Steel Structure Part
High-grade steel plates are cut, welded, and machined to form the main girders and end beams. The welded structure is heat-treated and inspected to ensure excellent strength, rigidity, and fatigue resistance.
3. Main Components
Essential components such as the hoist, trolley frame, and lifting mechanism are precisely manufactured and assembled to guarantee stability and smooth operation under heavy loads.
4. Accessories Production
Supporting elements including platforms, ladders, buffers, and safety rails are fabricated to facilitate safe maintenance and operation.
5. Crane Walking Machine
The end carriages and wheel assemblies are carefully aligned and tested to ensure smooth, vibration-free crane travel along the runway.
6. Production of the Trolley
The lifting trolley, equipped with motors, brakes, and gearboxes, is produced for high efficiency and long service life under continuous operation.
7. Electrical Control Unit
All electrical systems are assembled with premium components, allowing precise motion control and reliable overload protection.
8. Inspection Before Delivery
Before leaving the factory, each 30 ton double girder overhead crane undergoes full mechanical, electrical, and load testing to confirm optimal performance, durability, and compliance with international safety standards.
Designed for durability and long-term performance, double girder overhead cranes offer smooth operation, energy efficiency, and ease of maintenance, ensuring minimal downtime and lower operating costs. Whether integrated into new building structures or retrofitted into existing workshops, they enhance productivity, safety, and operational flexibility. Investing in a high-quality double girder overhead crane is a strategic decision that supports efficient material handling and long-term industrial growth.
