During hoisting, the mobile hood can be moved longitudinally at any time according to the production needs for hoisting materials, facilitating the lifting and transportation of materials. The electric hoists 5 can move laterally to the material stacking location to retrieve materials, lift and move them, and then lower them into the work area, replacing cantilever cranes or gantry cranes for hoisting refractory bricks, masonry materials, etc.
