Scope of application
|
It is mainly used for lifting and transporting molten metal in smelting workshop, rolling and other hot processing workshops for lifting and transporting hot items (melting non-metallic objects and solid metals whose temperature is lower than that of molten metal), and can also be used for machinery manufacturing, metal structure, assembly, etc. The work level of continuous production such as workshops and warehouses is busy with lifting and loading and unloading in busy places |
According to the busyness of use, it is divided into two working systems: intermediate and heavy. The intermediate is suitable for hoisting and loading and unloading in workshops and warehouses such as machinery manufacturing, metal structure, and assembly. Heavy grade is suitable for smelting workshops and handling work involved in continuous production |

1. Single motor double brake; 2. The main hoisting mechanism of casting cranes larger than 75 tons on the main production line should have two sets of drive systems. When one set of drive systems fails, the other set of drive systems should complete a working cycle under the rated weight; 3. The hoisting mechanism should have a double interlock protection device limit for the lifting limit position, and a lower limit position limiter should also be provided for cranes with a lifting height greater than 20 meters; 4. For the hoisting mechanism for hoisting liquid metal and other dangerous goods, at least two brakes shall be provided for each independent driving device; 5. When the crane is equipped with a weighing device, there should be obvious display devices in the appropriate positions of the driver's cab and the main beam; 6. The part of the crane that is directly exposed to high temperature radiation should be provided with heat insulation boards or heat insulation walls |
