[2] EXPLANATION OF MOMENT LIMITER DISPLAY
1. Actual load display
Continually displays the actual load of the hoisted load during
crane operations.
The actual load equals the total weight of the hook, hoisting
attachment, and hoisted load. When no load is applied, the
normal indication becomes “0.0” to “0.1”. If the indication does
not fall within the above range, contact us or our sales service
agent.
NOTES
• Due to the structure of load detection, a numerical value of
actual load display changes when the boom is raised and
lowered. Although the numerical value of the actual load
changes on a higher side when boom raising operation is
performed, this is not a fault.
• When the crane stops, the numerical value of actual load
display changes if there is swing of load.
2. Rated total load display
The rated total load (i.e. total weight of hook, hoisting attachment,
and hoisted load) which the crane can currently hoist is displayed.
It is calculated according to the conditions including the number
of wire falls of the hook and the working radius.
3. Actual working radius display
The current actual working radius is continually displayed during
crane operations.
The actual working radius refers to the horizontal distance from
the centre of slewing of the crane to the centre of the hook. The
deflection amount of the boom due to load is not included.
4. Rated working radius display
The current rated working radius is continually displayed during
crane operations.
The rated working radius refers to the maximum working radius
calculated from the boom length and actual load.
5. Boom length display
Continually displays the current boom length during crane
operations.
The boom length refers to the straight-line distance from the
boom foot pin to the sheave pin at the front end of the boom.
