Truck Outrigger Pads are durable UHMWPE support panels designed for mobile cranes, pump trucks, boom trucks and other outrigger-equipped machinery. Typical reference sizes include 450 × 450 × 25 mm and 600 × 600 × 40 mm square pads, plus 760 mm diameter × 50 mm and 900 mm diameter × 60 mm round pads. Recessed support areas, integrated carrying handles, multiple surface designs and reusable construction make the pads suitable for repeated heavy equipment setup.
Truck Outrigger Pads are heavy-duty UHMWPE support panels designed to create a larger and more stable contact area beneath the stabilizers of mobile cranes, truck-mounted cranes, concrete pump trucks, boom trucks, service vehicles, and other outrigger-equipped machinery. The pads help distribute concentrated outrigger forces across a broader supporting surface when the correct size, thickness, material structure, and setup method are selected.
The product shown features a solid square structure, a circular recessed support area, rounded corners, and integrated carrying handles. Selected designs may also use a reinforced or structured reverse surface, allowing the pad family to support different equipment setup requirements according to the actual product configuration.
Unlike temporary road mats, which are designed to create continuous vehicle routes, these pads are positioned directly beneath individual stabilizer or outrigger feet. Their primary purpose is to increase the effective support area between the equipment and the ground.
Truck Outrigger Pads are available in square and round formats with different thicknesses. The correct specification should be selected according to the maximum outrigger reaction, equipment foot dimensions, supporting ground condition, required load distribution area, and operating configuration.
Typical reference specifications include:
| Pad Format | Reference Size | Thickness | Approx. Weight |
|---|---|---|---|
| Square pad | 450 × 450 mm | 25 mm | Approximately 5 kg |
| Square pad | 600 × 600 mm | 40 mm | Approximately 14.4 kg |
| Round pad | 760 mm diameter | 50 mm | Approximately 22–23 kg |
| Round pad | 900 mm diameter | 60 mm | Approximately 35–38 kg |
Other practical thickness options may include approximately 25 mm, 30 mm, 40 mm, 50 mm, 60 mm, and 75 mm. Larger pads can provide a greater support area, while increased thickness can improve structural rigidity when the material and complete pad design are appropriate.
Actual product weight may vary according to exact dimensions, material grade, recessed areas, carrying holes, reverse-side structure, edge shape, and surface design.
Different equipment applications may require different pad shapes.
Square Truck Outrigger Pads provide a large usable support area and are convenient for stacking, transportation, and storage.
Round pads provide another practical option for equipment with circular stabilizer feet or applications where a round support format is preferred.
Common configurations include:
The final shape should match the actual stabilizer foot, required support area, handling method, storage space, and operating environment.
Selected pad designs combine two different functional surfaces in one product structure.
One side may include a circular recessed area that provides a defined positioning zone for the stabilizer foot. The reverse side may use a broader flat or reinforced structure according to the specific pad design.
This type of structure can provide different support arrangements for:
The two-sided structure should always be used according to the actual product design and approved equipment setup requirements. Not every surface configuration is suitable for every equipment load.
The circular recessed area visible on the upper surface creates a defined positioning zone for the stabilizer or outrigger foot.
Correct positioning is important because the support force should be transferred into the intended working area of the pad.
The recessed structure can help:
The diameter and depth of the recessed area should match the actual stabilizer foot and pad structure.
A stabilizer positioned close to an unsupported edge can create a different loading condition from one positioned over the intended support area.
The correct pad size should not be selected only according to the total weight or lifting capacity of a truck or crane.
Important selection factors include:
A basic approach to determining the minimum effective pad area is:
Maximum Outrigger Reaction Force ÷ Allowable Ground Bearing Pressure = Minimum Effective Pad Area
After the required area is determined, the pad material, thickness, stiffness, dimensions, and structural design should also be reviewed.
For additional information about this principle, you can read this external resource on outrigger pad sizing principles.
A mobile crane or pump truck does not necessarily transfer its total weight equally through every stabilizer.
The reaction acting through each outrigger can change according to:
For this reason, a universal statement such as “one pad supports a certain total truck tonnage” may not describe every real application accurately.
The maximum reaction at the individual outrigger position is a more useful starting point for pad selection.
The primary material used for these Truck Outrigger Pads is UHMWPE, or ultra-high-molecular-weight polyethylene.
This engineering plastic provides a practical combination of:
Unlike steel support plates, UHMWPE does not rust.
Compared with many traditional timber support products, the plastic material has low water absorption and does not depend on natural wood grain, knots, or changing moisture content.
After outdoor operation, mud and surface debris can be removed before the pad is inspected and stored.
The pads shown include bright integrated carrying handles positioned near the edges.
These provide defined handling points when the pad needs to be:
The number and position of the handles may vary according to pad size and weight.
Before lifting a pad, check:
Larger and heavier pads should be handled using methods suitable for their actual weight.
An outrigger transfers a concentrated reaction force through a relatively small stabilizer foot.
Truck Outrigger Pads increase the effective contact area between the stabilizer system and the supporting surface.
A larger effective support area can help reduce concentrated ground pressure when:
The objective is not simply to place any plastic plate under the equipment. The support system should be selected according to the complete operating condition.
Where possible, the stabilizer foot should be positioned over the intended working area of the support pad.
The recessed circular zone shown on this product provides a clear visual reference for positioning.
Correct positioning can help maintain:
The stabilizer should not be intentionally positioned close to an unsupported edge unless the pad system has been specifically designed and evaluated for that loading condition.
Truck Outrigger Pads can be used with different types of mobile lifting equipment.
Typical crane applications include:
The correct pad specification depends on the actual maximum outrigger reaction, supporting ground, stabilizer foot size, operating configuration, and required effective area.
Concrete pump trucks use stabilizers to create a larger operating base during pumping operations.
The forces acting through individual supports can change with the boom configuration and working position.
When selecting pads for a concrete pump truck, consider:
The same pump truck may require different consideration on concrete, asphalt, compacted gravel, firm soil, or softer surfaces.
Boom trucks and service vehicles often use outriggers during lifting, maintenance, utility, and material handling operations.
Typical equipment includes:
The pad dimensions should be selected according to the actual stabilizer loads and operating conditions rather than vehicle category alone.
Truck Outrigger Pads may be used on different surfaces when the ground and complete setup are appropriate.
Typical supporting surfaces include:
Before setup, inspect the area for:
The pad should have suitable support beneath its effective working area.
Square pads provide a practical shape for support area, stacking, storage, and transportation.
Typical square reference sizes include:
The approximately 450 × 450 × 25 mm format has a reference weight of around 5 kg.
The approximately 600 × 600 × 40 mm format has a reference weight of around 14.4 kg.
Smaller pads are easier to handle but provide less support area. Larger pads increase the contact footprint but also require greater consideration for weight, handling, and storage.
Round pads provide another option for stabilizer support.
Typical reference dimensions include:
A 760 mm diameter pad with approximately 50 mm thickness has a reference weight of around 22–23 kg depending on the exact design.
A 900 mm diameter pad with approximately 60 mm thickness may have a reference weight of around 35–38 kg depending on material and structural features.
The correct shape should be selected according to the equipment foot, required support area, handling method, and storage arrangement.
The product range can include different support surface structures.
Possible designs include:
The correct surface structure depends on the stabilizer foot, required positioning method, operating environment, and pad design.
Selected products can combine two functional sides within the same pad structure.
One side may focus on:
The other side may provide:
The exact use of each side should match the actual pad construction and approved operating method.
A major advantage of Truck Outrigger Pads is their reusable construction.
After equipment operation is completed, the pads can be:
The flat square and round formats allow multiple pads to be organized during transport and storage.
Reusable support pads should be inspected before demanding applications.
Check:
A damaged pad should be evaluated before being returned to heavy equipment support service.
The supporting ground should also be checked every time the equipment is repositioned.
Mud, gravel, sand, concrete residue, and other debris can remain on outrigger pads after outdoor operations.
Cleaning can help:
Large debris trapped beneath a pad should be removed before equipment loading because it can create concentrated support areas.
The regular pad shapes make the products suitable for organized equipment storage.
During storage:
Colored carrying handles can also make individual pads easier to locate around equipment and storage areas.
