Blocking under outrigger beam is allowed.

Blocking under outrigger beam is allowed.

• A. True
• B. False
• C. Only with supervisor
• D. Not ever

Answer: (B)

Outriggers are designed to transfer the crane’s load to the ground through their pads on a firm, level surface. Blocking under the outrigger beam isn’t allowed because it creates an unstable load path and can hide ground deficiencies. Blocks can shift, crush, or fail under load, and the outrigger pad may slip or settle differently than the blocking, which can compromise stability and lead to tipping. The proper approach is to place the crane on manufacturer-approved outriggers pads and, if needed, cribbing or shims only as specified by the crane manufacturer, not under the beam itself. If the ground isn’t suitable, adjust the setup (leveling, repositioning, or using approved mats) rather than blocking under the outrigger beam.
