To qualify: I say this without ever using an air assist hydraulic cylinder in an engine hoist.
Showing these pictures in order to point out what I see as a trade off. I think the air assist lacks some control
The first photo shows the angel the motor, had to start at with the transmission low to clear the tunnel. As the motor was lowered into position it require a bit of a dance..
Three moves, push in, remove some of the angle, lower hoist, repeat until set into place. Some times it was necessary to raise the hoist a bit to reestablish the angle.
The manual pump allowed slow and direct control of the amount of movement. If an engin hoist is only to be used to lift heavy objects, then by all means the air assist is a decent option.
