Work sites pose some inherent risks and dangers to their workers. When heavy machinery is introduced, this danger is taken to the next level. Cranes and other tall machinery must be operated carefully as to ensure the safety of everyone on the job. Basic physics tells us that the taller an object is, the more likely small movements at its base can cause the entirety of the structure to tip over. In the event of a crane toppling over, not only is expensive equipment ruined, but lives and thousands of dollars could be lost. Outrigger pads would be the best option when it comes to safety.

Thus, part of the safety protocol when using machinery like that is placing it on a level surface. While the ground may seem flat, it has subtle imperfections that make it unreliable for withstanding the immense pressure caused by heavy machinery. Thousands of pounds of force press upon the dirt, causing it to shift or cave in, which would spell disaster for your crane.

Luckily, there is a simple tool workers can use to maximize stability for their heavy machinery. An Outrigger Pad is a large, strong surface placed under the base of a crane. With a solid outrigger crane pad, the weight from the machinery is distributed more evenly. It essentially creates a bigger footprint for your equipment. Would you rather place your heavy machinery on a solid, flat surface or trust loose dirt or gravel? I'd take the Outrigger Pad any day, and thousands of workers across the country agree. Let's dive into what specifically makes Outrigger Pads so useful.

Wood vs High Density Polyethylene

Some workers opt for using wooden outrigger pads. Wood is inexpensive, and very easily sourced. While using wooden pallets as an outrigger pad may seem like a great idea, it has objective drawbacks that should sway you away from using them at your work site.

Wood is just not as structurally sound as a synthetic material. To make matters worse, wood is porous and can easily absorb water and chemicals. This can weaken the structural integrity of the wood causing it to break apart quickly and become unreliable. Another drawback of wood's porous nature is, as water is absorbed, the wood becomes much heavier, while offering less safety. The heavier your outrigger pad is the more likely someone is to injure themselves placing it, and the less likely it is that the pad will be used at all.

Mytee Products sells the safest outrigger Pads constructed from High Density Polyethylene, an extremely strong yet lightweight synthetic material. Crane pads made from HDP can absorb thousands of pounds of force, while only weighing in at around 30 pounds for a 2×2' pad. It is waterproof and chemical resistant, so it won't swell up with water and become heavier. Additionally, High Density Polyethylene will stand the test of time and hold its own against harsh elements. One High Density Polyethylene pad may be more expensive than a wooden one, but it will last significantly longer and is far safer.

Load Distribution with Outrigger Pads

As stated above, an outrigger pads purpose is to absorb the weight of heavy machinery and to give a stable surface for it to rest upon. They create a bigger footprint for machinery, stabilizing them more effectively than the ground. While a crane may seem stable on normal dirt, small changes can dangerously affect their structural integrity. For example, the dirt may buckle and shift under the weight of the machinery. Small movements at the base of a crane equate to huge, dangerous movements at its peak.

Wind may also cause the machinery to shift and tip over if not on solid ground. Now with outrigger pads, you won't need to worry about these issues. Mytee Products' Outrigger Pads can withstand a whopping 35,000 lbs of force from a 45 degree load or up to 60,000 lbs with a fully vertical load. It has a crush rating of 200 PSI. This massive load distribution capacity comes in a lightweight, water and chemical resistant pad. It is a great investment for any work site where heavy machinery is used.

Conclusion

Don't minimize the amount of safety on your job site by using a wooden outrigger pad or none at all. We want to use cranes and lifters as tools to get the job done, and not let their immense weight make them a safety liability. A Mytee Products' one of auto towing accessories High Density Polyethylene Outrigger Pad will maximize safety and profits at your job site.

50% of crane failure or total collapse is from improper use of outriggers. A proactive safety approach is to use outrigger pads on all setups. The outrigger pads will displace & reduce the PSI the ground ' sees ' from the point of contact of the outrigger/ shoe/ float/ pontoon on the equipment. The outrigger pads will also remind the personnel at the job site to ensure the outrigger system is being used correctly. Bigfoot is the first company to manufacture safety orange. This was done to address tripping hazards & make sure the outrigger system is deployed by bringing attention to the operator & other personnel on the job site.

The outrigger system shall be used according to the manufacturer's standards.

• The setup & leveling is critical on any setup or with any style of outrigger system on the equipment. Always follow the manufacturer's chart on level & grade % allowable for equipment to be set up.
• Get recent soil conditions. Getting a known ground bearing capacity ( GBC) will help with knowing what outrigger pad is the best fit.
• Check for location & know where utilities are overhead & underground.
• Maintain proper clearances on overhead power lines.
• Outrigger pads shall not be used to bridge any gaps or span over voids.

After the equipment is set up, level & according to the manufacturer recommendations & with Bigfoot outrigger pads, perform a dry run with spotters. The boom should be run over & around all the outriggers with a spotter not under the boom but looking at the outriggers. The spotter is looking to see if any of the floats are sinking, shifting, or sliding. If there is any issue, stop & stow the boom. Now is the time to re-check the equipment level, improve soil conditions or add Bigfoot outrigger pads & cribbing. There are some great starting points with setting up, but this will not cover all equipment set up. Having a lift director or person in charge on the job site to address setting up will help to avoid crane failure.

• Knowing the max PSI/ PSF ( this does not factor in shock or impact loading, which is common in DEMO & tree care or removal work. Speed plus mass equals force, which is measured in PSI/PSF & will go through the outrigger system).
• Size of outrigger/ shoe/ float/ pontoon on equipment
• Soil conditions

In many but not all setups, having this information will address the 3 times the square surface area on grade A soil conditions. The 3 times the square surface area on grade A soil conditions will displace the PSI from the equipment through the outrigger pad, depending on the GBC value that needs to be maintained. If there is a known GBC value needed & an engineer has values needing to be reached, Bigfoot can help.

Crane Failure

Cribbing or dunnage should not meet or exceed the height of the base outrigger pad. Example: A 36 X 36 at 2' ( P ) should not have cribbing or dunnage meet or exceed 36' on any setup. The bottom layer or base outrigger pad will be carrying the PSI ( when you see pictures of other outrigger pads with wood cribbing or dunnage underneath or on bottom, the cribbing or dunnage is carrying the load, the top pad is the cushion). Knowing this, the sheer value is needed on the setup as well. Bigfoot recommends using the same material to maintain consistency with sheer values, our custom composite cribbing is made from the same material as our outrigger pads.

Bigfoot's American custom composite has no grain lines. This allows the set up of outrigger pads & cribbing to be exceptionally user-friendly. This will eliminate the question of vertical pressure or out & down outrigger systems, which direction should the pads or cribbing face? The sheer value of Bigfoot's custom composite is the same in either direction. Bigfoot's material is not injected or extruded or 100% recycled material, these materials will have different directional shear values & need to be addressed in addition to setups. This is another area that Bigfoot has & can help with operators, lift directors, or personnel in charge. This will without question, using Bigfoot outrigger pads, help with setups & reduce human error to make sure the hard-working personnel are using STRENGTH/ STABILITY/ SAFETY on their job sites & equipment.

Safe Equipment Setup with Proper Cribbing and Blocking

Your SAFETY is our utmost concern at Bigfoot. We are dedicated to providing you with essential information you need to ensure the safe operation of cranes and heavy equipment across various ground surfaces. Employing appropriate cribbing and blocking techniques is pivotal in this process.

The Significance of Cribbing and Blocking

Cribbing establishes the sturdy foundation for elevating outriggers and stabilizers to greater heights, while blocking is instrumental in the even distribution of weight for heavy loads. These methods are integral to protecting operators from potential harm and guiding you in selecting the most suitable approach for supporting your equipment.

Key Definitions

• Ground Conditions: This term pertains to the ground's capability to withstand the weight of the equipment.
• Support Materials: This encompasses materials like blocking, mats, cribbing, or similar devices used to provide support.

Choosing the Appropriate Materials

When selecting materials for cribbing and blocking, consider the following:

• Make sure that the selected material can withstand the heavy loads exerted by the outrigger.
• Do not use materials exhibiting cracks, deformations, rot, bending, wear, or damage.
• Use materials larger than the outrigger's foot.
• Choose materials with ample thickness, width, and length to prevent load shifting, tipping, or excessive settling.
• Keep materials free from oil, grease, and debris, and keep them dry to prevent slipping.

Safe Usage of Cribbing and Blocking 

For secure utilization, please adhere to the following guidelines:

• Personnel should wear steel-toed boots, gloves, and eye protection when handling cribbing and blocking.
• Place materials on a solid, level base or foundation to ensure uniform weight distribution.
• Verify that no debris is beneath the cribbing or blocking, obstructing proper ground contact.
• Position the cribbing directly beneath the outrigger and stack it to prevent slippage.
• Regularly inspect cribbing and blocking during equipment operation for any indications of settling, slippage, cracking, bending, crushing, or shear failure.
• The cribbing should never exceed twice the width of the blocking base.

Determining the Correct Blocking Size

To ascertain the suitable size for cribbing or blocking, consider the following rules:

• Rule of 5: Divide the unit's maximum lifting capacity (in tons), e.g., 50 tons, by 5. This yields a requirement of 10 sq. ft. of cribbing or blocking.
• Rule of 3: Multiply the square footage of the crane's floats by 3. For instance, a 2×2 float equals 4 sq. ft. Multiply 4 sq. ft. by 3, resulting in a requirement of 12 sq. ft. of cribbing or blocking.

For more comprehensive guidance, we encourage you to consult OSHA's standard on cranes and derricks in construction ( Subpart CC). Your safety remains our top priority, and we are here to support you in the safe utilization of your equipment.
