Hiab hydraulics Question

[Timbersawz]

(making this searchable so other looking might find the info) Found some info via a mate for the hiab

The minimum spec for the hiab 650 is 2000 PSI and 50 litres per minute or 13 gpm gallons per minute

Hmmm, does your mate have a source for those numbers? The pressure seems low and the GPM seems high. For comparison, the Hiab 710 requires 8GPM at 3260PSI: http://www.anvilfire.com/temp/HIAB 710 Operators.pdf

Finally got hold of him, he got the numbers from another guy who works at a truck wreckers. I will try to follow it up

Usually knuckle booms are high pressure low volume. The older ones would be around 2500psi. The flow effects speed not how much it will lift. Slower may not be a bad thing with these units. Hiab crane out of Florida helped me with some info on the jack legs. PH# 407 246 1597 the rest I replaced with standard parts. CJ
