Let's see... less pressure, bigger motor, and you're still drawing lots more amps?
The only way I can see that happening is if both the RPM of the motor is too high, and the hoses are too small. And, while there is no "Natl Hydraulic Code" with a rule limiting the number of bends," bends DO matter, and affect the load.
In such situations, the resistance is in proportion to the cube of the flow rate... so again, it looks like they're trying to open the doors too fast. We're back to motor rpm.
There is such a thing as "inertia." It takes a bit to get those covers started in motion. This might be a place to try a "soft start" motor controller as well.
