Ultima Hooklift 01/2020

With the truck engine idling check the setting of the by-pass valve by checking to see that the
container locks are opening and closing without a delay and that the hook arm is moving front
and back. If the locks or hook arm (as well as any of accessories) are not moving, close the by
-pass valve to increase flow to the hydraulic actuators. The standard factory setting of the by-
pass valve is half open. The adjustment range of the valve is 4 - 10 gal/min.
The safety functions of the hooklift are the following:
 The hydraulic body locks must not open while tipping up (lift up only about 2 ft).
 The hydraulic body locks must not close when middle frame is up and rear frame is
down.
 The hook arm does not move back or front when the hydraulic body locks are closed.
NOTE: Hook arm can be moved front if the function ”Sliding While Tipping” is set on. If
also movement back is allowed, then check the operation of the ultrasonic sensors.
 End damping/floating function will start about 8” - 12” before the middle frame is down.
 The warning buzzer sounds during all hydraulic movements.
Accessories:
 When the hydraulic or manual front locks are closed, the main cylinders don’t move out
and the hook arm does not move rear or front.
 Tipping is not allowed if while the “Crane body on” sensor is active.
 The main cylinders protection circuit is limiting the operation pressure of main cylinder
out movement to 1600 psi after middle frame is lifted up over 20º angle.
 When the adjustable under run bar is out, the main cylinders don’t move out.
NOTE: If the hydraulic or electric operated under run bar is set to automatic or semi-
automatic function, then the under run bar moves in when the main cylinders are moved
out.

The fast speed tipping goes off after tipping angle exceeds 40º.
 The automatic lowering will stop if the control lever (joystick) is moved.
 When an additional control unit (Crane top seat control or radio controller) is switched on,
the Cabin controller unit screen will have “ -C2- “ in the display.
 Check also the safe operations of other possible accessories.
Check the operation of the hooklift also with a loaded container and known test load.
After the unit has passed the tests fill in the test report and write down any possible notes and
deviations.
By-pass valve adjustment:
-Turn clockwise to reduce the
speed
--Turn counter clockwise to in-
crease the speed
