(OP)
Retired military needs a device for home use to move a 1ft x 18 inch platform back and forth 2 feet; thrust +/- 50 lb. Cover distance in 10-14 seconds.
Malfunction/jam disconnect needed, plus operator capability to reverse direction of platform before completion of cycle.
Speed variation a plus.

Use a small three phase motor and a VFD. The Variable Frequency Drive will give you speed control reversing and may be programmed to provide jam detection/protection.

"Why not the best?"

RE: small motor & rigging medical project
When you use a shaft with lead 1/5 ' your specifications become:
Torque = 50 lb *1/5 ' = 10 lb.in
Average speed = 2 ft * 12 = 24 inch in 10 seconds or 720 rpm with lead 1/5'.
In the specAmotor site (www.specAmotor.com) you can use those two values (10 lb.in and 720 rpm) to find the best motor for your platform:
1) U12M4LR:forcedair electric motor from Danaher
2) Baldor BSM50N-175 with reduction
These motors are a bit overdimensioned but if you do not drive the motors 100% of the time than you can add a Duty Cycle and probably suffice with smaller motors.

And plenty of others. You may even find this kind of stuff cheap on eBay, Craig's List, or industrial equipment auction sites.

I third that suggestion.
