As an instructor with CICB, I’m fortunate to have extensive experience and knowledge at my disposal, which allows me to address a broad range of questions from rigging practices to industry standards and regulations. However, one area that frequently presents a challenge is outrigger pads. Questions like, “What is the best material for outrigger pads—synthetic, metal, or wood?” and “How should I choose the right pad size for a particular surface?” often come my way. These are complex inquiries that require careful consideration.
To answer these questions accurately, I must take into account several factors. Without being on-site and understanding the full scope of the lift, it would be imprudent to make even an informed guess. Fortunately, during the recent SC&RA convention in Glendale, AZ, I had the opportunity to attend a presentation on outrigger pad selection and usage that provided valuable insights.
As a member of the SC&RA, along with CICB and other instructors, we have access to a wealth of resources developed by NCCCO industry experts. One of the key takeaways from these resources is the importance of evaluating the material used for outrigger pads. Whether you opt for wood, metal, or synthetic, the selection process begins with a thorough inspection of the site and equipment.
The first step in any outrigger pad setup is to inspect the supporting surface. This ensures it is free of debris and properly compacted to support the pads and help the crane maintain a level stance. The next consideration is the crane’s outrigger system—whether stabilizers or outriggers are being used. These two elements serve different functions. Stabilizers help prevent tipping by enhancing the crane’s stability, while outriggers distribute the crane's weight over a larger area, increasing overall stability.
Once these basics are covered, we move into more specific site-related factors. Every site has its own variables that need to be taken into account, such as Outrigger Load Force, Maximum Outrigger Reaction Force, and Lift-Specific Peak Outrigger Reaction Force. This process can involve complex calculations, and I highly recommend SC&RA members access their extensive library for detailed information. For those who may not have access to these resources, SC&RA has created an acronym, PADSETUP, to guide the process:
P: Proper Planning
A: Always follow the manufacturer’s manual
D: Don’t take shortcuts
S: Situational Awareness
E: Environment
T: Tell your plan
U: Underground hazards
P: Proper Pads
By following the PADSETUP guidelines, you can ensure that you select the right outrigger pads for the job and use them safely and effectively.
As with any tool of the trade, outrigger pads must be inspected before each use or setup. After the setup, perform a dry run with a spotter to inspect the outriggers and outrigger pads. Check to see if the equipment is level, and then you’re ready to move forward with the job.
