- Outdoor using, including finishing coatings
- High reliability component
- Excellent operating performance
- Suited for general work
- Suit for both of outdoor and indoor

If want to use gantry crane, but client finish the establishment, could client avoid break the ground to install gantry crane?
Yep, at once the ground's concrete width is more than 20cm, then there is no need to dig the ground. Just need pave belt steel plate, and fix it on the concrete floor with bolts. Then weld the rails is okay.
Whether you can offer the matched spare parts?
Yep, as crane manufacturer, we offer all the related spare parts, such as motor, hoists, drums, wheels, grabs, hooks, rails, travel beams, enclosed bus bar etc.
