Frequently Asked Questions
What is a Box Type Single Girder Gantry Crane?
It is a type of gantry crane that features a single main girder fabricated in a closed box-type structure. This design provides high structural rigidity, excellent torsion resistance, and is lighter yet stronger compared to traditional truss structures, making it perfect for indoor and outdoor material handling.
What is the standard lifting capacity and span length?
Our standard lifting capacity ranges from 3 tons to 32 tons, with span lengths from 7.5 to 30 meters. However, both capacity and span lengths can be fully customized according to your specific project requirements.
Can this single girder gantry crane be used outdoors?
Yes. Our box girder gantry cranes are highly suitable for outdoor use. They are designed with weather protection features, including anti-corrosion surface coatings, rainproof covers for the electric hoist, and weatherproof electrical components.
What safety mechanisms are included in the crane?
For enhanced safety, the crane is equipped with integrated overload limiters, anti-collision systems, emergency stop buttons, travel limit switches, and rubber buffers to prevent structural damage during operation.
Do you support custom power supply configurations?
Yes, we support custom voltage configurations. While our standard power supply is 380V 50Hz 3Phase, we can customize the electrical system to match your local power standards (e.g., 220V, 440V, 460V, 60Hz).
What after-sales services do you provide?
We provide a comprehensive one-stop solution. This includes professional engineering support, online installation guidance, operational training, and a reliable supply of spare parts to ensure minimal downtime for your operations.
