Tech Tips
Avoid
Outrigger Failure:
For many years there were only
two positions where mobile crane outriggers could be used
for application of crane ratings. These were; (1) All
outriggers fully deployed and set, or (2) outriggers not
deployed or set. Modern cranes have changed dramatically,
and one of the most significant changes is
multiple
outrigger
configurations.
To make sure we are on the same path; Never has any crane
manufacturer approved "on outrigger" ratings when all
outriggers were not equally deployed and set to
specification. No manufacturer ever allowed only one, two,
or three of four outriggers set at any location to determine
a crane's safe rating. It was not uncommon, however, for an
operator working in tight quarters to position outriggers at
different locations and to refer all lift capacities to the
more conservative On-Rubber load chart. Seemingly the safe
approach to ensuring that any loss of stability would be
prevented by the outriggers being set, regardless of their
actual configuration. After all, the ratings being used were
conservative for on-rubber lifts only, right? Wrong!
Most of today's modern hydraulic cranes have multiple
outrigger positioning. Meaning, the outriggers have more
than just the fully out and down positioning. Many crane's
outriggers may now be set to 0%-extension and down,
50%-extension and down, or 100%-extension and down, and each
position has it's own load chart and ratings.
What is at issue is the location where outriggers may be
positioned and the reinforcing plates, sometimes called
"doublers," on the outrigger beams and inside the
outrigger box.
When a manufacturer incorporates reinforcement at intermediate outrigger positions the outriggers are
only to be used when set equally "at those reinforced
positions." Even when using the on-rubber ratings,
outriggers not set at the designated locations can, and do,
result in structural failure of the outrigger box and
possibly the beam itself.
Make sure your crane operators are aware of this structural
limitation. Set up correctly for maximum safety. Contact
your crane supplier for clarification of outrigger
positioning.
Your crane may vary from this example so be sure to check
your crane operator's manual carefully.
