| There
are many different types of jib crane available, either floor
or wall mounted, providing different slew angles
from 180º to 360º continuous. Fully powered versions offer
smooth jib crane arm rotation (slew), hoist travel and
lift operation.
The standard jib crane design for an
area with no headroom restrictions is the over braced type. When available headroom is
limited then an under braced or knuckle jib crane will
provide maximum height of lift. When access
becomes awkward, a knuckle jib crane (not shown) may
provide the answer. Provision for an elbow in the
jib crane arm allows even greater manoeuvrability.
