20 Ton Double Girder Mobile Gantry Crane Shipped To Uzbekistan

In the sectors of heavy metal structure manufacturing and warehousing logistics, efficient and reliable material handling equipment is essential for maintaining production schedules. We recently successfully customized a 20-ton mobile double-girder gantry crane with an electric wire rope hoist for a client in Uzbekistan. The client from Uzbekistan specializes in the processing and assembly of metal frameworks. During our consultations, we identified their core requirements and set up the technical crane drawing for them. The unit underwent rigorous pre-assembly and full-load testing at our factory; it has now been successfully shipped and will soon be put into operation on the client's metal frame lifting and assembly line.

1. Full Variable Frequency Control: Variable frequency speed regulation is applied to the hoist, trolley, and gantry travel mechanisms, ensuring smooth, shock-free starts and stops and precise inching/positioning-ideal for the alignment and placement of precision metal frames.

2. C-Hook with Safety Latch: Equipped with a 360-degree rotating C-hook and a spring-loaded safety latch to prevent accidental detachment, making the lifting of metal frames both flexible and secure.

3. Wheel Design: The wheels feature a rubberized finish and 360-degree rotation capability; combined with a 4-meter wheel track, this ensures smooth movement across the bay while protecting the workshop floor.

4. Reinforced Steel Structure: The main structure utilizes thickened steel, offering exceptional wind load resistance and fatigue durability, ensuring stable and reliable performance even in the harsh outdoor environment of Uzbekistan.

5. Comprehensive Safety Protection: Standard features include a full suite of safety devices-such as overload protection, limit switches, and emergency stop functions-to ensure the safety of both personnel and equipment.

 

With the wide variety of lifting equipment available on the market, selecting a gantry crane that suits your specific operating conditions is crucial:

1. Determine the load and lifting attachments: Consider not only the weight of the cargo but also the weight of the lifting attachments, while allowing for a 20%–25% safety margin. For instance, a client needing to lift 12 tons would make the most prudent choice by selecting a 20-ton mobile gantry crane.

2. Assess dimensions and span: Verify that the span and lifting height are sufficient to accommodate the passage of the widest and tallest metal frames in your workshop.

3. Match the operating frequency: An 8-hour daily schedule constitutes high-frequency operation; therefore, a crane with a duty classification of A4 or higher is essential, ideally paired with a variable frequency drive to minimize mechanical wear.

4. Choose a mobile gantry crane manufacturer offering customization: From factory pre-assembly to full-load testing, the advantage of a customized solution lies in its ability to precisely meet your actual production requirements.
