Sloppy gearbox????

Is that motor/gearbox all that's preventing landing gear collapse?
Looks a bit "flimsy"
Or are there internal features within the landing gear that prevent collapse, say, should the motor's shaft shear off?

The landing gear are long screws with bevel gears at the top. The legs have captive nuts that move up/down as the screw is turned by the motor through the bevel gears. Even if the motor or cross shaft were to fall off, the legs won't collapse.
On one occasion, we were breaking camp and only one leg would come up. Turned out that the shaft on the leg farthest from the motor had sheared off where it bolts to the cross shaft. Lucky for me, I carry a 1/2" drive cordless drill and was able to remove the cross shaft, hook the drill to what was left of the input shaft to the leg and raise it. Of course, I had to use my hydraulic jack to get the weight off the leg so the drill would have enough torque to lift it.
