UHMWPE Crane Outrigger Pads are reusable heavy-duty support panels designed for mobile cranes, concrete pumps, boom trucks and hydraulic stabilizer systems. Available reference sizes range from 400 × 400 mm to 2000 × 2000 mm, with square, rectangular and round configurations and different surface and handle options.
UHMWPE Crane Outrigger Pads are solid engineering-plastic support panels designed for mobile crane outriggers, concrete pump stabilizers, truck-mounted cranes, boom lifts, aerial work platforms and other machinery equipped with hydraulic support legs.
The primary purpose of an outrigger pad is to provide a larger geometric support area beneath the original equipment foot. The increased contact area helps distribute the stabilizer reaction across a broader supporting surface while providing a reusable intermediate panel between the machine and the surface below.
These heavy-duty support pads are manufactured from ultra-high-molecular-weight polyethylene, commonly abbreviated as UHMWPE. Square, rectangular and round formats can be produced with different surface textures, handle arrangements, outside dimensions and thicknesses to match different equipment configurations.
The supplied product information lists square dimensions ranging from approximately 400 × 400 mm to 2000 × 2000 mm, with thickness options extending from approximately 40 mm to 150 mm. Final dimensions must be selected according to the actual stabilizer reaction, original equipment-foot size, required support area and supporting surface condition.
The following table provides practical reference dimensions based on the supplied product information. These sizes are product options rather than universal safe-working-load ratings.
| Reference Pad Size | Practical Thickness Range | Typical Application |
|---|---|---|
| 400 × 400 mm | 40–60 mm | Compact stabilizers, service vehicles and smaller lifting equipment |
| 500 × 500 mm | 40–70 mm | Utility vehicles, compact cranes and maintenance equipment |
| 600 × 600 mm | 40–80 mm | Mobile cranes, boom trucks and concrete pumping equipment |
| 700 × 700 mm | 50–80 mm | Medium stabilizer and hydraulic support applications |
| 800 × 800 mm | 50–80 mm | Concrete pumps, aerial platforms and medium heavy machinery |
| 1000 × 1000 mm | 60–100 mm | Large mobile cranes and heavy equipment stabilizers |
| 1200 × 1200 mm | 80–120 mm | Large-format crane and machinery support |
| 1500 × 1500 mm | 80–150 mm | Heavy equipment requiring an enlarged support footprint |
| 1600 × 1600 mm | 100–150 mm | Special large-format stabilizer support applications |
| 2000 × 2000 mm | 100–150 mm | Extra-large machinery and engineered support arrangements |
The approximately 400 × 400 × 40–60 mm and 500 × 500 × 40–70 mm formats provide compact options where storage space and repeated positioning are important.
The approximately 600 × 600 × 40–80 mm and 700 × 700 × 50–80 mm formats provide a practical balance between support area, panel weight, thickness and vehicle-storage requirements.
Medium and large formats such as approximately 800 × 800 × 50–80 mm, 1000 × 1000 × 60–100 mm and 1200 × 1200 × 80–120 mm can be considered for concrete pumps, mobile cranes, boom trucks and other stabilizer-equipped machinery.
Large panels measuring approximately 1500 × 1500 mm, 1600 × 1600 mm or 2000 × 2000 mm can have substantial finished weights. Mechanical lifting and handling equipment may be required for transportation, placement and storage.
Thicknesses of approximately 120–150 mm should be treated as special heavy-duty options. They should not be presented as universal specifications without reviewing the maximum individual stabilizer reaction, load position, UHMWPE grade and supporting conditions.

UHMWPE stands for ultra-high-molecular-weight polyethylene. It is a thermoplastic polyethylene containing extremely long molecular chains.
For a general material explanation, see the Wikipedia article about ultra-high-molecular-weight polyethylene.
Practical material characteristics for UHMWPE Crane Outrigger Pads include:
The finished product properties can vary according to molecular weight, UHMWPE grade, manufacturing method, dimensions, temperature and duration of loading.
UHMWPE can deform gradually under sustained stress through a process known as creep. For this reason, the thickness and outside dimensions should be selected according to the real load and operating duration rather than relying only on a general product-size chart.
UHMWPE has a lower density than steel, allowing many support pads to be transported and repositioned more easily than comparably sized metal plates.
Lower finished weight can help with:
Large-format solid pads may still be too heavy for safe manual handling. The correct lifting method should be selected according to the finished product weight and workplace requirements.
Crane support pads are repeatedly transported, positioned, loaded, recovered and stacked.
During normal operation, they may experience:
The toughness and abrasion resistance of UHMWPE make it suitable for reusable industrial support components.
Products showing cracks, severe permanent deformation, deep cuts, excessive surface wear or damaged handles should be removed from demanding service and evaluated before reuse.
Mobile cranes, boom trucks, concrete pumps and aerial work platforms frequently operate outdoors.
The support pads may be exposed to:
The extremely low moisture absorption of UHMWPE helps it retain a reusable solid-plastic structure in wet operating environments.
Unlike steel support plates, UHMWPE does not rust. However, the pads should still be cleaned and inspected after wet, muddy or contaminated use.
UHMWPE Crane Outrigger Pads can be produced in square, rectangular or circular formats.
Square pads provide:
Round pads can provide:
The outside shape should be selected according to the original equipment-foot shape, available storage area and required effective support footprint.
Different working surfaces can be produced according to the equipment-foot structure and handling requirements.
Common options include:
A textured surface can make the intended upper working face easier to identify and can provide additional surface texture beneath the stabilizer foot.
Surface textures should not be treated as a substitute for correct pad sizing, sufficient thickness, suitable ground conditions or proper equipment-foot positioning.
Carrying handles can be installed to support transportation, positioning and storage.
Available handle structures may include:
Before moving a pad, inspect:
The carrying handle is intended for transportation and positioning. It should not be treated as a structural component carrying the stabilizer reaction.
A hydraulic outrigger transfers a concentrated reaction through a relatively small original equipment foot.
UHMWPE Crane Outrigger Pads provide a larger geometric contact area beneath that foot.
The performance of the complete support arrangement depends on:
A larger outside dimension provides a larger geometric footprint, but dimensions alone should not be treated as a universal safe-working-load rating.
The support pad should not be selected only according to total machine weight or maximum crane lifting capacity.
Individual outrigger reactions can change according to:
Important selection information includes:
Each stabilizer position should be evaluated independently because reactions and supporting conditions can differ around the same machine.
Two crane pads with identical outside dimensions can respond differently when their thicknesses are different.
For example, a 600 × 600 mm pad may be produced as:
A 1000 × 1000 mm pad may be produced as:
Panel thickness can affect:
The final thickness should be selected according to the actual stabilizer reaction, equipment-foot dimensions, required support area, operating duration and surface conditions.
UHMWPE Crane Outrigger Pads can be used with many types of stabilizer-equipped machinery.
The correct outside dimensions, thickness, shape and handle arrangement should always be matched to the actual equipment-support point.
Before applying the equipment load, confirm that:
The working surface should remain free from excessive oil, mud, gravel, metal debris and other hard objects.
Reusable crane pads should be inspected before every demanding equipment setup.
Check:
After use, remove mud, sand, gravel, oil and other contaminants from the working surfaces.
During storage:
