Hoisting with Boom Raised
4.
When you are working in a cramped location,
you may not have enough room
to lower the boom prior to
hoisting. In such cases, it is
permissible to hoist the machine
while the boom is still up. Proceed
as follows.
• Sling chains or wire ropes used for hoisting
should be at least 10 meters long.
• Set the boom angle to 60°
or lower (that is, at
least 10°
below the maximum raise angle of
70°
).
• If sling chains or wire ropes contact the
boom, place pads on the boom to protect it.
