Thanks Alan. Too slow for me. Regds, Hugh

Hi Hugh,

I got a response from "Lenco" last night.

Alan,

The time is 2 seconds per inch of stroke for all actuators and Hatchlifts.

Of course because the Lenco are so powerful you can set them up

with a different leverage or gearing to speed up the motion of whatever

you are driving. Possibly a better way of comparing the different actuators

is to look at the amps they draw & work out the wattage. If one actuator

is twice the wattage of another it should be able to be set up to work twice

as fast providing you select the right stroke length

Alan

Howdy Frank, thanks for the info. 1 inch a second is pretty slow. OK for a manip possibly if it has a high load. Which model was the Firgelli you bought? Looks like they are 1”/sec as well. I would like to find a good one like the teledynes. The Lenco is certainly good value. Rgds, Hugh

Hello Hugh. I don't know how fast they are but the Lenco's and Minnkota trim tab actuators are probably similar in speed. I seem to remember the 2-1/2 inch stroke on the Minnkota's was 1 inch per second.

Typically the more powerful they are the higher the gearing and slower speed.

After dis-assembling the Firgelli actuators I have to investigate how oil compensation might be accomplished, I saw how cheaply they are made. Not even close to the Lenco's brochure as to quality.

At $259 or so, they seem like a fairly inexpensive and powerful actuator.
