What is Crane Outrigger Pads

Crane outrigger pads, also known as crane mats or crane outriggers, are heavy-duty plates that are placed under the outriggers of a mobile crane to provide stability and support. The outriggers are extendable arms that are designed to stabilize the crane during lifting operations by spreading its weight over a larger area.

Features of Crane Outrigger Pads

Moisture and Chemical Resistance

Wood is highly porous and soaks up any liquids it encounters. Crane Outrigger Pads are constantly exposed to groundwater, precipitation, and any potential contaminants within the groundwater. This can include motor oil, road salts, gasoline, and other chemicals.

Durability

The strength of UHMW comes from its long chains of high-mass molecules. It has the greatest impact strength of any thermoplastic that’s currently being manufactured. Our Crane Outrigger Pads are designed to flex slightly on rough terrain, which protects them from breaking when under stress. Wood is susceptible to breaking and splintering, and also expands and warps due to moisture absorption, which weakens the pad.

Reduced Weight

Crane Outrigger Pads typically weigh 60 percent less than traditional crane pads and mats, potentially saving you thousands of pounds of trailer capacity. This savings increases trailer capacity or can eliminate the need for an additional trailer.

Lower Operation Costs

Decrease set up and tear down time with rigging-friendly hardware. Multiple lifting hardware options allow you to select the option best suited for your operation. Crane Outrigger Pads are also easy to clean and will not absorb moisture, bacteria or other contaminants, eliminating site-to-site contamination and rot or rust issues and concerns.

Types of Crane Outrigger Pads

High-Density Polyethylene (HDPE) Crane Mats

These crane mats are made from HDPE, which is resistant to water, oil, and chemicals. They are lighter than steel pads and have a greater load-bearing capability of up to 200 tonnes.

Plywood Outrigger Pads

These are made from certified exterior plywood with exterior polyurethane glue and are designed to increase stability and reduce “point load” on hydraulic cranes with extended support outriggers.

Recycled High-Density Polyethylene Pads

Outrigger pads made from 100% recycled HDPE, which are hard-wearing, do not splinter, and maintain their supporting capabilities under normal use.

Materials of Crane Outrigger Pads

01/

Steel
Known for its high strength and durability, steel is a popular choice for outrigger pads, particularly for heavy-duty applications. It provides excellent load-bearing capability and is resistant to wear and tear. However, steel can be heavy and may corrode over time if not properly maintained.

02/

Aluminum
Aluminum outrigger pads offer a lighter alternative to steel, which makes them easier to handle and transport. They are also resistant to corrosion, which extends their service life. Despite being lighter, aluminum pads can still support significant loads, though typically less than comparable steel pads.

03/

Composite Materials
Composites, such as fiberglass-reinforced plastic (FRP), are becoming increasingly popular due to their high strength-to-weight ratio and resistance to chemicals and corrosion. These materials do not conduct electricity, which can be a safety benefit in certain environments. Composite pads are also less likely to damage sensitive surfaces.

04/

Ultra-High Molecular Weight Polyethylene (UHMWPE)
UHMWPE is known for its exceptional impact resistance and low coefficient of friction. It is also highly resistant to abrasion and chemical attack. While UHMWPE pads are durable and long-lasting, they may not be as widely available as other materials and can be more expensive.

How to Choose Crane Outrigger Pads

Determine Crane Capacity and Load Requirements

Identify the maximum load your crane will lift, including both the lifted load and any additional counterweights or attachments. This information will help you determine the necessary load-bearing capacity for your outrigger pads.

Assess Ground Condition

Evaluate the surface where the crane will be set up. Factors like soil type, compactness, and the presence of obstacles or underground utilities can influence pad selection. Hard, flat surfaces may require less reinforcement, while soft or uneven ground might necessitate more robust pads.

Calculate Outrigger Footprint

Measure the area between the outriggers when fully extended to determine the required size of the outrigger pads. The pads must cover this entire footprint to provide uniform support.

Choose Appropriate Pad Material

Select a material that suits your specific needs. Consider factors such as the pad's strength, durability, resistance to environmental conditions (like corrosion or UV exposure), and weight. Common materials include steel, aluminum, composites, UHMWPE, and timber.

Crane Outrigger Pads Design Procedure and Sizing

Calculate the Force Exerted on the Ground
First, calculate the total force exerted by the crane on the ground. This includes the weight of the crane itself, any attachments, and the load being lifted. The force is typically given in pounds or kilograms.

Determine Ground Bearing Pressure
Obtain the allowable ground bearing pressure for the soil or surface on which the crane will operate. This is the maximum pressure the ground can handle without yielding. It can be determined through soil testing or consulting a geotechnical engineer.

Calculate the Required Pad Area
Divide the total force by the allowable ground bearing pressure to determine the required area of the crane pad in square feet or square meters. This calculation ensures that the pad size is sufficient to distribute the load within the limits of the ground bearing capacity.

Determine Pad Dimensions

Once the total required area is known, you can calculate the dimensions of the pad. If assuming a square pad, take the square root of the area to find the length of each side of the square pad. Always round up to ensure safety.

Select Pad Material and Thickness

Choose a material that can withstand the load and environmental conditions. Common materials include high-density polyethylene (HDPE), steel, or reinforced composite materials. The thickness of the pad should also be sufficient to prevent bending or breaking under load. Manufacturers often provide recommendations based on the pad’s material and size.

Consult Manufacturer’s Guidelines and Safety Standards

Always refer to the crane manufacturer’s guidelines for specific recommendations on outrigger pad usage. Additionally, adhere to local safety standards and regulations to ensure compliance and safety during crane operations.

How to Install Crane Outrigger Pads

Clear the Area

Before setting up your outrigger pads, make sure the area is clear of any debris or obstacles that could affect stability.

Extend the Outriggers

Extend the outriggers on your crane to their full length and lower them onto the ground.

Place the Outrigger Pads

Place the outrigger pads on the ground under each outrigger. Make sure they’re centered and flat on the ground, with no air pockets or gaps between the pad and the ground.

Lower the Crane

Once the pads are in place, slowly lower the crane onto the pads. Watch for any signs of movement or instability and adjust the position of the pads as needed.

Test Stability

Once the crane is fully lowered onto the pads, test its stability by performing a light lift or swing. If the crane is stable, you can begin your work.
