500mm UHMWPE Crane Outrigger Pads are reusable heavy-duty support panels featuring solid 500 × 500 × 50 mm construction, diamond-pattern anti-slip surfaces and reinforced rope carrying handles. The approximate finished weight is 11–12.5 kg, making this size suitable for mobile cranes, boom trucks, concrete pumps and hydraulic stabilizer systems when matched to the actual equipment reaction.
500mm UHMWPE Crane Outrigger Pads are heavy-duty engineering-plastic support panels designed for mobile crane outriggers, concrete pump stabilizers, boom truck support legs, truck-mounted cranes, aerial work platforms and other machinery equipped with hydraulic stabilizers.
The product shown features a solid 500 × 500 × 50 mm square structure, a diamond-pattern anti-slip working surface, finished outside edges and reinforced rope carrying handles. Matching pads can be stacked together for transportation, vehicle storage, warehouse organization and repeated equipment setup.
The 500 × 500 mm footprint provides a practical geometric support area beneath compatible crane and machinery stabilizer feet. The 50 mm solid thickness offers a useful balance between panel stiffness, finished weight, storage space and routine handling.
Unlike temporary access mats that are laid continuously to form a vehicle route, 500mm UHMWPE Crane Outrigger Pads are positioned individually beneath hydraulic support feet. Their main purpose is to increase the geometric contact area between the original stabilizer foot and the supporting surface.

The approximate weight is calculated from a substantially solid UHMWPE panel. Actual finished weight may vary according to material density, surface texture, handle holes, edge machining, rope structure and manufacturing tolerances.
The dimensions and weight are product references rather than universal safe-working-load ratings. Permitted use must be determined according to the maximum individual outrigger reaction, equipment-foot dimensions, supporting surface, pad condition and required safety factor.
The approximately 500 × 500 × 50 mm specification is suitable where a compact square support footprint is required without using a very large or excessively heavy panel.
This size provides:
The stabilizer foot should remain within the intended central working area. It should not be positioned close to an unsupported edge or directly over a damaged section.
In addition to the main 500 × 500 × 50 mm product, related square UHMWPE support pads can be produced in several practical dimensions.
| Reference Size | Approximate Solid Weight | Typical Application |
|---|---|---|
| 400 × 400 × 40 mm | Approximately 5.9–6.3 kg | Compact stabilizers and service vehicles |
| 500 × 500 × 40 mm | Approximately 9.3–10 kg | Utility vehicles and smaller lifting equipment |
| 500 × 500 × 50 mm | Approximately 11–12.5 kg | Mobile cranes, boom trucks and maintenance vehicles |
| 500 × 500 × 60 mm | Approximately 13.9–15 kg | Thicker compact stabilizer support |
| 600 × 600 × 50 mm | Approximately 16.7–18 kg | Mobile cranes and concrete pumping equipment |
| 600 × 600 × 60 mm | Approximately 20–21.5 kg | Medium stabilizer-support applications |
| 800 × 800 × 60 mm | Approximately 35.7–38 kg | Concrete pumps and medium heavy machinery |
The listed weights are approximate values. Surface grooves, recessed areas, carrying holes and different material grades can change the final product weight.
Increasing the outside dimensions provides a larger geometric footprint, while increasing the thickness generally increases panel stiffness and finished weight. Neither dimension alone should be treated as a universal load rating.
The upper working face of the reference product contains a raised diamond-pattern surface.
This surface structure can provide:
The anti-slip pattern should not be treated as a mechanical locking system. Correct pad sizing, suitable ground conditions and accurate stabilizer-foot positioning are still required.
Mud, oil, gravel, stones, metal fragments and other hard debris should be removed from the textured surface before equipment load is applied.
The solid square construction provides a simple and reusable intermediate support surface beneath a crane or heavy-equipment stabilizer.
A square panel can provide:
The pad should be supported across a suitable area of its lower surface. It should not bridge a deep hole, unstable edge, large unsupported void or unsuitable opening.
The original stabilizer foot should remain inside the main support area and should not rest across the outside edge of the pad.
The product shown includes flexible rope carrying handles fitted along the outside edges.
The handles provide defined gripping points when the support pads need to be:
Before moving a pad, inspect:
The rope handles are intended for transportation and positioning. They should not be treated as structural lifting points or as components carrying the crane load.
The reference image shows several matching 500mm UHMWPE Crane Outrigger Pads stacked together as a complete support set.
A stackable design can help with:
Stacking for storage does not mean multiple flat pads can automatically be stacked beneath an operating stabilizer. Any multi-layer support arrangement should be reviewed for total height, alignment, lateral movement and stability.
UHMWPE stands for ultra-high-molecular-weight polyethylene. It is a thermoplastic polyethylene composed of extremely long molecular chains.
For a general material explanation, see the Wikipedia article about ultra-high-molecular-weight polyethylene.
Practical UHMWPE characteristics for crane-support products include:
UHMWPE can be considered where support pads will be repeatedly transported, positioned, loaded, recovered and exposed to abrasive or wet operating environments.
Finished properties can vary according to molecular weight, material grade, manufacturing process, dimensions, operating temperature and loading duration.
Chemical resistance should not be interpreted as universal resistance to every substance. Compatibility depends on the chemical, concentration, contact time, operating temperature and selected UHMWPE grade.
500mm UHMWPE Crane Outrigger Pads may be repeatedly moved, stacked, positioned, loaded and returned to storage.
During regular operation, the pads may experience:
The toughness and abrasion resistance of UHMWPE make it suitable for reusable industrial support products.
Pads showing cracks, severe permanent deformation, deep cuts, damaged handle holes or excessive surface wear should be separated and evaluated before reuse.
Crane outrigger pads may be exposed to rain, wet ground, mud, washing water and humid storage conditions.
UHMWPE has extremely low moisture absorption and does not rust like an unprotected steel support plate.
The pads should still be cleaned and inspected after wet, muddy or contaminated operation.
A hydraulic stabilizer transfers a concentrated reaction through a relatively small original equipment foot.
500mm UHMWPE Crane Outrigger Pads provide a larger geometric contact area beneath that foot.
The performance of the complete support arrangement depends on:
A larger geometric contact area can reduce the average pressure applied to the supporting surface. However, product dimensions alone do not establish a universal safe-working-load rating.
The correct pad should not be selected only according to total machine weight or maximum crane lifting capacity.
Individual stabilizer reactions may change according to:
Important selection information includes:
Each stabilizer position should be evaluated independently because loads and supporting conditions can differ around the same machine.
Two support pads with the same 500 × 500 mm outside dimensions can respond differently when their thicknesses are different.
Related thickness options may include:
Panel thickness can affect:
The thickest available pad is not automatically the correct choice. The final selection should balance equipment reaction, supporting conditions, finished weight and operational requirements.
500mm UHMWPE Crane Outrigger Pads can be considered for different types of stabilizer-equipped machinery.
The 500 × 500 × 50 mm format should only be selected when its dimensions and structural properties are suitable for the actual equipment-support point.
Before applying equipment load, confirm that:
The diamond-pattern surface should remain free from excessive oil, mud, gravel, metal fragments and other hard debris.
Reusable support pads should be inspected before every demanding equipment setup.
Check:
After operation, remove mud, sand, gravel, oil and other contaminants from the working surfaces.
