Match index not sure the best way

Good afternoon

I have 3 sheets
picking sheet gets updated every few hours then gets delete at end of shift with new next days work
Timeslot Tracker sheet gets replaced at end of shift
Pick order sheet will get all the information from the 2 other sheets to make a list from
only the headers will stay

I have set up a sample of how I am trying to set up the Pick order sheet

I have tried to use vlookup I think match index will be better cause its needs to look left and right
and return the same Truck ID and load numbers and pick up time with different Order ID

On pick order sheet
The order the table needs to be sorted is Truck Id Pick up time
the problem I have is the load number is not unique there can be different Order ID under the same Load number Which is why the vlookup I was trying to do is not working cause it have to return
mult results from the same load number

I have attached a sample with the first 6 Truck ID's some days we can have up to 60 truck ID's with up to 150 Order ID Trying to sort this data out has been a lot of work

The main problem I have is the only thing the time slot tracker and picking sheet have in common are the load no it is it in any random order I have deleted all other data on the sheets that are not needed for the sample

picking and Timeslot tracker Sheets cells cant change order as they are pulled from our system at work via a export

any help would be great
