Double-Girder Hydraulic Mobile Gantry Crane | Install & Commission Guide

December 11 , 2025

To ensure that our U.S. customer receives a fully reliable product with zero issues during installation and operation, we performed a complete powered test run before shipment. This pre-delivery inspection confirms that every mechanical, electrical, and hydraulic system works smoothly under actual operating conditions. Powder coating should be applied only after the equipment has been installed and tested to ensure it is in good working order. This will effectively prevent damage to the paint surface caused by the installation process.Below is a detailed overview of the equipment tested.


Overview of the Customized Gantry Crane System

 

The equipment supplied this time includes a 15-ton double girder mobile gantry crane equipped with a hydraulic lifting mechanism, paired with a low-headroom fixed-type electric chain hoist. The solution is designed for flexible indoor and outdoor material handling, especially for facilities that require adjustable lifting heights and smooth, precise load control.


1. Double Girder Mobile Gantry Crane with Hydraulic Height Adjustment

 

Double-Girder-Hydraulic-Mobile-Gantry-Crane Double-Girder-Gantry-Crane

Rated Load Capacity: 15 Tons

The crane is engineered for stable and efficient lifting of heavy components up to 15,000 kg, meeting demanding industrial handling requirements.

Span: 5 Meters

A compact 5-meter span ensures excellent maneuverability in limited workspaces while maintaining structural stability under load.

Adjustable Total Height: 4500–6300 mm

The hydraulic lifting system allows the overall crane height to be adjusted between 4.5 m and 6.3 m.
This feature is ideal for:

  • Passing through gates or low-height areas

  • Adapting to different working environments

  • Achieving better lifting coverage and operational flexibility

Adjustable Lifting Height: 3200–5000 mm

The lifting range can be flexibly set from 3.2 m to 5 m, allowing operators to handle various materials at different heights without compromising safety.

PU Solid Wheels

Equipped with PU (polyurethane) solid tires, the gantry crane provides:

  • Smooth and quiet movement

  • Excellent floor protection

  • High load-bearing performance

  • Maintenance-free operation

These wheels are suitable for factories, warehouses, and outdoor flat surfaces.

Working Class: A5 with Frequency Converter

The crane is built to A5 duty classification, supporting frequent lifting cycles and high working intensity.
The variable frequency drive (VFD) ensures:

  • Smooth acceleration and deceleration

  • Reduced mechanical impact

  • Better load stability

  • Enhanced safety and durability


2. Low-Headroom Fixed Shaft-Type Electric Chain Hoist

 

To match the gantry crane, we provided a 15-ton low-headroom electric chain hoist, specifically designed to maximize lifting height under restricted ceiling conditions.

Rated Load: 15 Tons

The hoist is capable of lifting heavy materials safely and efficiently during continuous operation.

Lifting Height: 5 Meters

A total lifting height of 5 meters meets various application needs in manufacturing, assembly, and warehouse operations.

Lifting Speed: 2.3 m/min

The optimized lifting speed of 2.3 m/min delivers smooth, precise load handling and positioning.

Working Class: M5

With an M5 duty rating, the hoist is built for medium-to-heavy usage, ensuring long service life and reliable performance in demanding work environments.


3. Pre-Delivery Test Run: What We Checked

 

Before shipment, our engineers performed a complete powered test run to ensure all systems meet international quality and safety standards. The inspection covered:

  • Electrical system performance under full load simulation

  • Hydraulic lifting stability and height adjustment precision

  • Hoist lifting, lowering, and braking performance

  • VFD smooth speed control and soft-start operation

  • Traveling system alignment and movement quality

  • Limit switches and safety protection devices

  • Noise and vibration levels

  • Overall structural integrity and weld quality

All systems passed the test and are now ready for final packing and delivery.


Conclusion

 

This customized 15-ton hydraulic mobile gantry crane with a low-headroom chain hoist is designed to offer high flexibility, strong lifting performance, and durable operation for our U.S. customer. By conducting a powered test run before shipment, we guarantee that the equipment will be ready for fast installation and safe operation upon arrival.
