I have come across a problem that for the life of me I can't seem to figure out. I'm sharing this here in the hopes that the amazing community here can help push me in the right direction.
The problem goes like this, in my project I require 4 High torque BLDC Motors each having an output torque of 105 N-m or approximately 1070 kg-cm. Due to size constraints we need to go with geared motors. The problem starts here, I have come across a 12 rpm planetary gear DC motor with encoder that has the stall torque of around 584 kg-cm with a gear ratio of 721:1. On further research I can't seem to be able to find a motor with a higher torque than this. I would love to get a guidance from experts regarding what should I do next?
Should I increase the gear ratio or order a custom DC motor more suited to my application.
N.B: Keep in mind this will be used in a vehicle with a load capacity of around 400-500kg. I have verified all calculations and need to source the DC motors now for this load capacity.
I look forward on hearing your views regarding this problem

Edit Update: The project is a automated warehouse management system in which we are developing an AGV (Automated Guided Vehicle). 400-500 kg will be the weight on it after stacking bins on top. Just like shown in the link: daifuku-logisticssolutions.com/image.jsp?id=3767
We can't go lower than 10 rpm (velocity of 0.11 m/s) since we have to cover 100 m in 15 minutes max. I'm attaching a link for related to the custom build DC motor directindustry.com/prod/electric-motor-power-pty-ltd/…
