Stackable HDPE Outrigger Pads are reusable heavy-equipment support panels featuring solid square structures and multiple rope carrying handles. Practical reference sizes include 400 × 400 × 40–60 mm, 600 × 600 × 40–70 mm, 800 × 800 × 60–80 mm and 1000 × 1000 × 70–100 mm for mobile cranes, concrete pumps, boom trucks and other stabilizer-equipped machinery.
Stackable HDPE Outrigger Pads are solid 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 square solid-panel structure, a flat or lightly textured working surface and multiple high-visibility rope handles positioned around the panel edges. Matching pads can be stacked together as a complete equipment-support set for transportation, vehicle storage, warehouse organization and repeated use.
Unlike temporary roadway mats that are installed continuously to create a vehicle-access route, outrigger pads are placed directly beneath individual stabilizer feet. Their primary purpose is to increase the geometric contact area between the original equipment foot and the supporting surface.
The final pad dimensions and thickness should be selected according to the maximum individual outrigger reaction, original equipment-foot dimensions, required support area, HDPE material grade and underlying surface condition.
The precise dimensions of the products shown cannot be confirmed from the photograph alone. Based on the supplied product information, the following dimensions are practical reference sizes for this type of solid HDPE crane support pad.
| Reference Pad Size | Reference Thickness | Typical Application |
|---|---|---|
| 300 × 300 mm | 30–50 mm | Compact stabilizers and smaller service equipment |
| 400 × 400 mm | 40–60 mm | Utility vehicles and compact crane support |
| 500 × 500 mm | 40–60 mm | Small cranes, boom trucks and service vehicles |
| 600 × 600 mm | 40–70 mm | General mobile cranes and pump truck stabilizers |
| 700 × 700 mm | 50–70 mm | Medium stabilizer support requirements |
| 800 × 800 mm | 60–80 mm | Concrete pumps and medium heavy equipment |
| 1000 × 1000 mm | 70–100 mm | Large mobile-equipment support |
| 1200 × 1200 mm | 80–100 mm | Heavy equipment and large crane support |
| 1500 × 1500 mm | 100–150 mm | Special large-format support applications |
The approximately 300 × 300 × 30–50 mm and 400 × 400 × 40–60 mm formats provide relatively compact support options where vehicle-storage space and repeated handling are important.
The approximately 500 × 500 × 40–60 mm and 600 × 600 × 40–70 mm formats provide a practical balance between geometric support area, finished product weight and equipment-storage requirements.
Medium-size products such as approximately 700 × 700 × 50–70 mm and 800 × 800 × 60–80 mm provide broader support areas for mobile cranes, concrete pumps and boom trucks.
Larger panels such as approximately 1000 × 1000 × 70–100 mm, 1200 × 1200 × 80–100 mm and 1500 × 1500 × 100–150 mm require additional consideration for finished weight, transportation, vehicle storage and mechanical handling.
These dimensions are reference product options rather than universal safe-working-load ratings. The permitted load cannot be determined from outside dimensions alone. Final selection should consider the actual stabilizer reaction, panel stiffness, equipment-foot position and supporting surface.
| Specification | Typical Reference |

| Product type | Stackable crane and heavy-equipment outrigger support pad |
| Primary material | HDPE |
| Main shape | Square |
| Alternative shapes | Rectangular, round and clipped-corner formats |

Final dimensions, thickness, HDPE grade, surface finish, edge design and handle arrangement should be selected according to the actual equipment and operating requirements.
The defining structural feature of Stackable HDPE Outrigger Pads is the use of matching square panels that can be stored together as an organized equipment set.
A stackable square structure can provide:
The panels should be stacked only for transportation and storage unless an approved support arrangement specifically permits another use. Several flat outrigger pads should not automatically be stacked beneath an operating stabilizer without an appropriate engineering assessment.
The product image shows multiple rope handles arranged around the panel edges.
These handles provide several gripping positions when the pads need to be:
High-visibility handle colors can also make the gripping points easier to identify around machinery and storage areas.
Before moving a support pad, inspect:
The rope handles are intended for transportation and positioning. They should not be treated as structural components carrying the crane or stabilizer load.
Large solid panels may require coordinated team handling or suitable mechanical equipment even when several carrying handles are installed.
The primary material used for Stackable HDPE Outrigger Pads is high-density polyethylene, commonly abbreviated as HDPE.
HDPE is a polyethylene material known for its relatively high strength-to-density ratio. It is also resistant to many solvents and is commonly used in products requiring durable, moisture-resistant plastic construction.
For a general material explanation, see the Wikipedia article about high-density polyethylene.
Practical HDPE characteristics for reusable equipment-support pads include:
The physical properties of HDPE can vary according to material grade, production method, panel dimensions and operating temperature.
Chemical resistance should not be interpreted as universal resistance to every substance. Compatibility depends on the exact chemical, concentration, temperature, contact time and selected material grade.
Crane support pads are repeatedly transported, positioned, loaded, recovered and stored.
During normal use, the panels may experience:
HDPE provides a practical combination of impact performance, durability and relatively low finished weight for general industrial outrigger-pad applications.
Products showing visible cracks, severe deformation, deep cuts or damaged handle-attachment points should be evaluated before returning to demanding service.
Mobile cranes, concrete pumps and boom trucks frequently operate outdoors.
The support pads may be exposed to:
The low water absorption of HDPE is useful for reusable support panels operating in wet or changing outdoor environments.
The pads should still be cleaned and inspected after wet, muddy or contaminated operations.
A hydraulic stabilizer transfers a concentrated reaction through a relatively small original equipment foot.
Stackable HDPE 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 pad size alone should not be interpreted as a universal safe-working-load rating.
The correct support pad should not be selected only according to the total machine weight or maximum crane lifting capacity.
Individual outrigger reactions can change according to:
Important product-selection factors include:
Each support position should be evaluated independently because loads and supporting conditions can differ around the same machine.
Two pads with identical length and width can respond differently when their thicknesses are different.
For example, a 600 × 600 mm panel may be considered in several thicknesses:
An 800 × 800 mm panel may be considered as:
Panel thickness can affect:
The final thickness should be selected according to the actual stabilizer reaction, equipment-foot dimensions, required support area, HDPE material grade and supporting surface.
Stackable HDPE Outrigger Pads can be used with many types of stabilizer-equipped machinery.
The correct product dimensions, thickness and material grade should always be matched to the actual equipment-support point.
Correct positioning is important when using an outrigger support panel.
Before applying the equipment load, confirm that:
The upper working surface should remain free from excessive oil, mud, gravel and metal debris.
Reusable support panels should be inspected before every demanding equipment setup.
Check:
After use, remove mud, sand, gravel, oil and other debris from the main working surfaces.
During storage:
