Step-by-step explanation:
To determine the maximum amount of weight that can be held up by the HIAB 8108-2 crane at a boom length of 20 feet, we need additional information specific to that crane model.
The information provided in the reference does not mention the HIAB 8108-2 crane, so we cannot calculate the maximum weight based solely on the given information. It is recommended to refer to the manufacturer's specifications or consult the operational manual of the HIAB 8108-2 crane to obtain accurate information about its maximum weight capacity at different boom lengths.
