So im building another service truck and i was hoping to get away from pto powered cranes, as the idle/dpf issue is something i wish to avoid. My new crane is an imt 2020, 5k crane, which currently is electric over hydraulic, this imt crane unlike many also can be run with a pto pump, which increases speed, and gives the option for hydraulic outriggers. Most people choose either pto or electric, i wish to have both. Electric for inside pto for outside, this is the easy part.
Now im hoping to use a lincoln 305g efi to power the hydraulic pump, lucky for me kohlers can run small hydraulic pumps off the front of the flywheel. Also the 305 engine placement makes it easy to build a drive plate, now im hoping to be able to run a 5-6 gpm pump at around 2300 psi, which would require around 8-9hp.
My general concerns is the speed of the engine, first i hope to run the engine around 1500 rpms, im confindent in building an engine controller, not sure if the welder will like it, second i must be able to control start and stop the welder via the crane remote, again seems easy to tap into the wiring. My biggest concerns comes from the hydraulic pump dragging down the engine while its at full speed. Now i will never run the crane and welder together, but the hydraulic pump will eat some hp, even when it is in bypass mode, ie pump returned to tank. I have thought about an electric clutch for the hydraulic pump, but it would be difficult to find one to adapt to front drive setup.
Also i know this will likely kill my warranty, which i dont care.
