5.2 DIAGRAM OF WORKING RADIUS AND LIFTING HEIGHT
• The working radius/lifting height shows relationship between working radius, boom angle
and lifting height above ground of this machine with no load hoisted, and deflection of the
boom is not included.
• Stage “3” in the diagram of working radius and lifting height indicates that one half
portion of the “
mark” is extruding from the 2nd stage boom.
1. In the figure on the right, point A denotes a boom angle
and point B denotes a lifting height above ground.
The same working radius applies to point A and point B.
2. The “diagram of working radius and lifting height” shows
the relationships between the working radius, boom
angle and lifting height at no load, allowing for no
deflection in the boom.
A deflection occurs in the boom when an object is hoisted,
which causes the working radius to widen slightly.
The rated total load decreases with increase in the
working radius. Actual crane operation requires the
planning of work, allowing for sufficient clearance more
than that provided in the diagram.
