2.3 FULCRUM
The SCORPIO cranes’ arm is supported on the Column by the Fulcrum. The way that the fulcrum
is attached to the column is with 8 screws (Ref. DIN7991 M10x30mm) from the column to the fulcrum.
To see all of them, the inside column needs to be lifted at least 10cm.
There is an extra screw used to apply friction to the swing
movement of the crane. To have access to it, align it with the hole in
the column side when assembly.
2.3.1 MECHANICAL COMPONENTS OF THE FULCRUM
The fulcrum is the element of the crane that allows the arm to
perform movements in the panoramic axis and the tilt axis using
different bearings.
The main mechanical components in the fulcrum for the user are
the Pan and Tilt brakes and the fluid screws.
The fluid screws adjust the friction of the movement independently
for pan or tilt axis. To adjust the pan fluid, use the screw in the
attachment for the column: the more tight, the more friction (fig. 2.30).
To adjust the tilt fluid there are 2 set screws in the left side of the
fulcrum: the more tight, the more friction (fig.2.31). There is also a
guiding pin in the left side of the telescopic arm that makes that the
arm only fits in one way into the fulcrum.
The brakes of the crane are located in the fulcrum. The pan is only
accessible from the left side of the crane. The tilt brake can be
activated from both sides of the crane. Both brakes are not blockers:
when they are used, the crane is just hold in place by friction pads
and it can be moved if the force applied to move it is stronger than
the friction of the pads. If the crane needs to be blocked, use straps
to lock it.
The pan brake is activated with the knob handle located in the left
side of the fulcrum. It is a brake pad system and is tightened by
moving the handle clockwise looking it from the bottom. The handle
can be pulled down to disengage it and engage it again in another
position to be able to apply more tension if needed.
