Manual extensions
Manual extensions are additional boom sections, which are placed in the
crane outer booms and secured by pins and check pins; they have a maxi-
mum capacity, indicated on the plate, independent from the crane configura-
tion.
(!) WARNING (!)
Manual extensions are not protected by the lifting moment limiting device.
Before lifting the load make sure that its weight does not exceed the
capacity indicated on the plate.
Manual extensions can be extracted from the rest position and be operative,
once the security pins have been removed, with the outer boom in sliding
position.
(!) Verify that the area is suitable for this operation and there are no
unauthorized persons in the working area.
Do not permit the extension to slide out at speed as this will damage the
stroke end stops.
Do not try to align the holes (slots) for the locking pins with your fingers;
always use a suitable tool.
Always remember that when operating with implements, their tare
weight must be deducted from the capacity of the crane.
When manual extensions are in place, fit the locking pins and secure them
with the check pins to prevent accidental escape.
