Bridge Gantry Crane
The safety technical requirements of Bridge Gantry Crane
- Check the anchor bolt, can not have loose, fall off and broken.
- Check reducer box, daily temperature cannot exceed the permitted the bearing temperature. When temperature more than room temperature 40 ℃, should check whether the bearing damage, improper installation or lack of lubricating grease, load time is too long, Operation has or not stagnation, etc.
- Check the lubrication parts. When the wire rope electric hoist is used at the initial stage, change the lubricant once every three months, and clean the box, remove metal scrap.
