Recessed Crane Outrigger Pads are reusable UHMWPE support panels featuring solid square structures, central circular positioning recesses and multiple carrying handles. Practical reference sizes include 600 × 600 × 50–60 mm, 800 × 800 × 60–80 mm and 1000 × 1000 × 80–100 mm for mobile cranes, concrete pumps, boom trucks and other stabilizer-equipped machinery.
Recessed Crane Outrigger Pads are heavy-duty UHMWPE support panels designed for mobile crane outriggers, concrete pump stabilizers, boom truck support legs, truck-mounted cranes, aerial work platforms and other machinery that uses hydraulic support legs during operation.
The product shown features a solid square panel structure, a circular recessed positioning area in the centre of the upper working surface and multiple high-visibility carrying handles around the panel edges. Matching pads can be stacked together as a complete equipment support set for transportation, storage and repeated use.
The central circular recess provides a clearly defined positioning area for a compatible crane or machinery stabilizer foot. This structure distinguishes the product from completely smooth, rough-surface, cross-ribbed and deeply grooved support pads.
The recess diameter and depth should be selected according to the actual equipment-foot dimensions. One fixed recess size should not be assumed to fit every mobile crane, concrete pump or boom truck.
The precise dimensions of the pads shown cannot be confirmed from the product image alone. The following specifications are practical reference sizes for this type of solid UHMWPE crane support pad.
| Reference Pad Size | Practical Recess Range | Typical Application |
|---|---|---|
| 500 × 500 × 50 mm | Ø200–250 mm | Compact stabilizers and smaller mobile equipment |
| 600 × 600 × 50 mm | Ø250–300 mm | General boom trucks and truck-mounted cranes |
| 600 × 600 × 60 mm | Ø250–320 mm | Thicker general-purpose crane support |
| 700 × 700 × 60 mm | Ø300–350 mm | Medium stabilizer support requirements |
| 800 × 800 × 60 mm | Ø350–400 mm | Concrete pumps and medium heavy equipment |
| 800 × 800 × 80 mm | Ø350–420 mm | Thicker pump truck and crane support |
| 900 × 900 × 80 mm | Ø400–450 mm | Larger crane and pump truck stabilizers |
| 1000 × 1000 × 80 mm | Ø450–500 mm | Large mobile equipment support |
| 1000 × 1000 × 100 mm | Ø450–520 mm | Large heavy-equipment stabilizers |
| 1200 × 1200 × 100 mm | Ø500–600 mm | Large-format equipment support applications |
The approximately 500 × 500 × 50 mm and 600 × 600 × 50–60 mm formats provide relatively compact options where equipment storage and repeated handling are important.
The approximately 700 × 700 × 60 mm and 800 × 800 × 60–80 mm formats provide broader geometric support areas for medium-size cranes, concrete pumps and boom truck stabilizers.
Larger products such as approximately 900 × 900 × 80 mm, 1000 × 1000 × 80–100 mm and 1200 × 1200 × 100 mm require additional consideration for finished weight, transportation, vehicle storage and handling methods.
The recess dimensions shown above are practical reference ranges rather than fixed production standards. The final recess diameter should provide appropriate clearance around the actual stabilizer foot without removing excessive material from the primary support section.
A practical recess depth may range from approximately 5 mm to 15 mm, depending on the total pad thickness, equipment-foot geometry and required remaining material thickness.
Final dimensions, thickness and recess geometry should always be selected according to the maximum individual stabilizer reaction, original equipment-foot dimensions, required support area, UHMWPE stiffness and supporting surface condition.

The defining feature of Recessed Crane Outrigger Pads is the circular positioning recess located near the centre of the upper working surface.
The recessed area can provide:
The recess should not be described as a universal locking mechanism. Its function depends on the relationship between the recess diameter, recess depth, stabilizer-foot dimensions and equipment position.
If the recess is too small, the original equipment foot may not sit correctly. If the recess is unnecessarily large or deep, too much material may be removed from the main support section.
The circular recess should be designed using the actual stabilizer-foot measurements rather than the total size or weight of the machine.
Important measurements include:
For example, an equipment foot measuring approximately Ø280 mm may require a recess slightly larger than the original foot diameter to allow practical positioning. The final clearance should be confirmed from the equipment dimensions and production drawing.
The circular positioning area should normally remain close to the intended centre of the support panel unless the equipment structure requires another approved position.
The depth of the circular recess affects the remaining thickness of the UHMWPE directly beneath the stabilizer foot.
A shallow recess can provide a visible positioning reference while retaining most of the original panel thickness.
A deeper recess creates a more pronounced positioning area but removes more material from the main support section.
Recess depth should therefore consider:
The deepest possible recess is not automatically the best option. The structure should provide sufficient positioning guidance while maintaining an appropriate solid support section.
The product combines its circular recess with a solid square UHMWPE outside structure.
A square support panel provides:
The stabilizer foot should remain within the intended recessed working area. The support pad should not span a large unsupported void or be positioned close to an unstable edge.
The reference product uses multiple flexible carrying handles around the pad edges.
The handles provide several gripping positions when the panels need to be:
Multiple handles can be especially useful for larger panels because they allow coordinated team handling.
The presence of handles does not mean every pad can safely be lifted by one person. Large-format panels may require suitable mechanical handling equipment.
Before moving a pad, inspect:
The handles are intended for transportation and positioning. They are not structural components supporting the equipment load.
The product image shows several matching Recessed Crane Outrigger Pads stacked together.
A stackable design can help with:
The storage surface should be reasonably level and suitable for the combined weight of the complete stack.
The primary material used for Recessed Crane Outrigger Pads is ultra-high-molecular-weight polyethylene, commonly abbreviated as UHMWPE.
UHMWPE is a thermoplastic polyethylene with extremely long molecular chains. It is associated with high toughness, impact strength, extremely low moisture absorption, low friction and strong abrasion resistance.
For a general material explanation, see the Wikipedia article about ultra-high-molecular-weight polyethylene.
Practical material characteristics for reusable crane support pads include:
Chemical resistance should not be interpreted as universal resistance to every substance. Compatibility depends on the exact chemical, concentration, temperature, exposure time and selected UHMWPE grade.
A crane or heavy-equipment stabilizer transfers a concentrated reaction through its original equipment foot.
Recessed Crane Outrigger Pads create a larger geometric support area beneath that foot while providing a visible central positioning section.
The performance of the complete support arrangement depends on:
A larger outside dimension provides a larger geometric footprint, but panel dimensions alone should not be treated as a universal safe-working-load rating.
The correct support pad should not be selected only according to total crane weight or maximum rated lifting capacity.
Individual outrigger reactions can change according to:
Important selection factors include:
Each support position should be evaluated separately because equipment reactions and ground conditions can differ around the same machine.
Recessed Crane Outrigger Pads can be used with stabilizer-equipped machinery that has compatible circular or near-circular support feet.
The recess diameter, panel dimensions and thickness should always be matched to the actual equipment foot and support requirements.
Mobile crane outrigger reactions can vary according to boom direction, working radius, lifted load, crane geometry and outrigger extension.
Before selecting a support pad, consider:
The same crane may require different support considerations at different positions or operating configurations.
Concrete pumps and boom trucks also use hydraulic stabilizers to create a wider operating base.
Important selection factors include:
Each stabilizer location should be checked independently because reactions and ground conditions can differ around the same vehicle.
Correct positioning is particularly important when using a recessed support panel.
Before applying equipment load, confirm that:
The recessed working area should remain free from excessive mud, oil, stones and metal debris.
Reusable support pads should be inspected before each demanding equipment setup.
Check:
After operation, remove mud, sand, oil, gravel and other debris from the primary working surfaces.
During storage:
