M A E D A Mini-Crawler Crane Section 4 – CRANE OPERATION
3/2019 MC305C-3 4-51
Do Not Pull Sideward, Draw in, and Hoist
Diagonally
Pulling sideward, drawing in, or hoisting
diagonally applies unreasonable force on the
machine. It not only damages the machine body,
but also is dangerous. Never operate in these
ways.
The hook must come right above the centre of
gravity of the load hoisted.

Do Not Operate Violently
Do not operate the lever suddenly.
Especially, the "slewing", "boom lowering", and
"hook lowering" must be operated at low speed.

Do Not Access into Working Radius

such as permitting an operator to go under the
hoisted load.

out according to the rated total load chart.
