5-74t Double Girder Hook Bridge Cast Crane
Double beam ladle crane is the main equipment during the steel making process. The crane is applicable in steel making workshop to transfer liquid steel or metal under the high temperature, dusty working environment. With the development of steel industry, the foundry crane need to work more frequently. So the foundry crane must be safety and reliable, and even when some parts damaged, Our crane can keep the ladle not falling or rollover. The framework of our crane is simple, and can be maintained very quickly in order to ensure the steel making production continuously.
Now we can supply foundry crane capacity up to 350 ton. Also according to customer's requirement we can provide special design.
1. Strong box type, welding by robot;
2. Thermal-protective coating is added at the bottom of the main girder.
