Crane Load - Moving Static Load

Dear All,

I am seeking some help designing the beam/column for an overhead crane that will change its position from Point1-8 as shown in the figure below.

Few are my queries.

1. What is the best possible option for applying this type of moving static load?

2. Can I develop the ENVELOP of these 8 moving static load cases below and call it into LOAD COMBINATION as a single LOAD CASE? as now I have to separately create 8 load combinations for each position

Awaiting a kind response.
