The permissible load of an Mam-
mut crane hook (Fig. 19.1) is
15 kN (1.5 t).
Handling
1. Open the safety lever as far as
possible (Fig. 19.3).
2. Push the crane hook over
the panel profile until the claw
engages completely in the
groove.
3. Release the safety lever and
press it back to its start position
so that the crane hook is locked
completely (Fig. 19.4).
Attention
Always use two crane hooks,
even when moving single panels.
Always attach the crane hooks
symmetrically to the centre of
gravity.
When moving single horizontal
panels, both crane hooks must
be attached at the centre of
gravity over the cross stiffeners
of the profile (Fig. 19.6). When
moving several panels at once,
make sure each crane hook is
attached at a panel joint to pre-
vent the crane hook slipping.
When to replace the crane
hook
If the reference dimension
exceeds 61 mm, the crane hook
must be replaced immediately.
This also applies if only one side
of the hook exceeds this dimen-
sion (Fig. 19.2).
Safety check
Always check the crane hook
before use. Do not overload the
crane hook. Overloading causes
damage. A damaged crane hook
is not capable of supporting the
full load and its safe use can no
longer be guaranteed.
Safety regulations
When using our products, the
federal, state and local codes and
regulations must be observed.
Also observe the operating
instructions delivered with the
crane hook.
