Hi
I have the details for the Drive gearbox and the lift motor.


The Gearboxes for the wheel drive are made by a company called, Pujol from Spain.
The model number is LAC40/10/120-11.
Ratio 10:1
Let me know if you find a supplier as I may need spares one day
The motors are Bosch 750W 24V.


The motor gearbox for the lifter is from a stair lift.
Made by Electric Motor Developments. EMD
The model number is PM63/50-VC24-GB2-75-1BK
RPM 37, the final drive via chain is reduction 2.5:1
This gives the total drive ratio as 187.5:1 reduction, lifting arm length 250mm
This is the same manufacturer for the motors in Seraph, Pilgrim, Spiderbot and the weapon motor in Gabriel.
Worm drive Gearboxes are very bad as far as efficiency is concerned I would think this one is no more than 45% but the advantage is the capacity to handle loads of torque in a small box and most of all for this application they can't be "back or load driven" so no need for a brake.

Hope the info helps
