UHMWPE HDPE Outrigger Blocks are reusable long-strip support components featuring solid rectangular structures, reinforced end holes and flexible rope carrying handles. Practical reference sizes include 600 × 150 × 100–150 mm, 610 × 180 × 150 mm, 800 × 200 × 100–120 mm and 1000 × 200 × 100–150 mm for crane legs, hydraulic jacks, equipment leveling and heavy machinery support.
UHMWPE HDPE Outrigger Blocks are heavy-duty engineering-plastic support components designed for crane outriggers, hydraulic jacks, stabilizer legs, vehicle recovery equipment, heavy machinery leveling and temporary equipment-support applications.
The product shown features a solid long-strip structure, reinforced holes near the ends and flexible rope carrying handles. Its narrow rectangular shape makes it different from conventional square crane pads and allows the block to be positioned beneath compatible support feet or incorporated into an approved multi-block support arrangement.
These support blocks can be manufactured from ultra-high-molecular-weight polyethylene or high-density polyethylene. UHMWPE can be selected where strong impact toughness and abrasion resistance are important, while HDPE provides a practical combination of rigidity, durability and product weight for many general support applications.
Optional surface designs can include a smooth working face, textured surface, anti-slip grooves or a rubber-coated contact layer. The final material, dimensions, surface structure and handle arrangement should be selected according to the equipment reaction, support-foot dimensions and operating conditions.
The exact dimensions of the products shown cannot be confirmed from the photograph alone. Based on the visible long-strip structure and commonly used industrial support-block formats, the following dimensions are practical reference options.
| Reference Block Size | Approximate Solid Weight | Typical Application |
|---|---|---|
| 500 × 150 × 100 mm | Approximately 7–8 kg | Compact jack support and equipment leveling |
| 600 × 150 × 100 mm | Approximately 8–9 kg | Utility vehicles and smaller hydraulic stabilizers |
| 600 × 150 × 150 mm | Approximately 12–14 kg | Crane-leg support and modular cribbing arrangements |
| 610 × 180 × 150 mm | Approximately 15–17 kg | Heavy equipment and vehicle-support applications |
| 800 × 200 × 100 mm | Approximately 15–17 kg | Longer support footprint beneath machinery |
| 800 × 200 × 120 mm | Approximately 18–20 kg | Medium heavy-equipment support |
| 1000 × 200 × 100 mm | Approximately 19–21 kg | Large support-foot and load-distribution applications |
| 1000 × 200 × 150 mm | Approximately 28–31 kg | Heavy-duty temporary machinery support |
| 1200 × 250 × 100 mm | Approximately 28–31 kg | Extended support footprint for heavy equipment |
The weights above are approximate values for substantially solid polyethylene blocks. Finished weight can change according to the selected material grade, machined holes, recessed sections, surface grooves, rubber layers and carrying-handle structure.
The approximately 500 × 150 × 100 mm and 600 × 150 × 100 mm formats provide compact support options where vehicle-storage space and repeated handling are important.
The approximately 600 × 150 × 150 mm and 610 × 180 × 150 mm formats provide thicker modular structures for crane support, vehicle recovery, industrial maintenance and equipment-leveling operations.
Longer formats such as approximately 800 × 200 × 100–120 mm, 1000 × 200 × 100–150 mm and 1200 × 250 × 100 mm provide an enlarged support footprint in one direction.
These dimensions are product references rather than universal safe-working-load ratings. Final dimensions must be confirmed according to the maximum reaction at one equipment-support point, block orientation, material grade, support height and condition of the surface beneath the block.

The main structural feature of UHMWPE HDPE Outrigger Blocks is the long rectangular body.
Compared with a conventional square pad, the long-strip structure can provide:
The block should be supported across an appropriate area of its lower surface. It should not bridge a deep opening, unstable edge or large unsupported void.
The equipment foot should remain within the intended support area and should not be positioned close to an unsupported block edge.
The reference product includes holes near the ends of the block with flexible rope handles passing through the openings.
This structure provides defined gripping points when the support blocks need to be:
The rope handles may be manufactured from braided synthetic rope and can include protective sleeves or grip sections.
Before moving a block, inspect:
The carrying ropes are intended for transportation and positioning. They should not be treated as structural load-bearing components during crane or equipment operation.
The position and diameter of the end holes should be selected according to the block dimensions and required carrying-rope structure.
Important design considerations include:
The hole should provide suitable clearance for the rope without unnecessarily removing solid material from the end of the support block.
Sharp hole edges should be avoided where they could cause repeated abrasion or cutting of the carrying rope.
The supplied product information refers to an optional rubber-coated UHMWPE or HDPE support product.
A rubber contact layer may be considered where the support block is used on a relatively hard or smooth surface and additional surface grip or floor protection is required.
Possible benefits of an optional rubber-coated surface include:
The rubber layer, adhesive system and polyethylene substrate must be suitable for the actual load, temperature, chemical exposure and operating conditions.
A rubber-coated surface does not replace correct support-block sizing, suitable ground conditions or proper equipment-foot positioning.
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 reusable support blocks include:
UHMWPE can be selected where the support blocks will be repeatedly transported, positioned, loaded and exposed to abrasive surfaces.
The finished product properties can vary according to molecular weight, material grade, processing method, block dimensions, operating temperature and duration of loading.
HDPE stands for high-density polyethylene. It is a thermoplastic polyethylene with relatively low chain branching and a comparatively high degree of crystallinity.
For a general material explanation, see the Wikipedia article about high-density polyethylene.
Practical HDPE characteristics for support-block applications include:
HDPE properties can vary according to molecular weight, crystallinity, material grade and manufacturing method.
Chemical resistance should not be interpreted as universal resistance to every substance. Compatibility depends on the chemical, concentration, operating temperature and duration of exposure.
The correct material for UHMWPE HDPE Outrigger Blocks should be selected according to the actual equipment and operating requirements.
Important considerations include:
UHMWPE is generally considered where high toughness, impact performance and abrasion resistance are priorities. HDPE can provide a practical combination of rigidity, strength, durability and cost for many general support applications.
UHMWPE HDPE Outrigger Blocks may be repeatedly moved, stacked, positioned, loaded and recovered.
During regular operation, the blocks may experience:
The selected polyethylene grade should provide suitable impact and wear performance for the intended support application.
Blocks showing cracks, severe deformation, deep cuts, damaged holes or excessively worn carrying ropes should be separated and evaluated before returning to demanding service.
Crane support and machinery-leveling operations are frequently carried out in wet or outdoor environments.
The support blocks may be exposed to rain, wet ground, mud, washing water and humid storage conditions.
UHMWPE and HDPE have low moisture absorption and do not rust like unprotected steel support blocks.
The blocks should still be cleaned and inspected after wet, muddy or contaminated operation.
A crane leg, hydraulic jack or machinery stabilizer transfers a concentrated reaction through a relatively small original support foot.
UHMWPE HDPE Outrigger Blocks provide a solid intermediate support structure beneath that contact point.
The performance of the complete support arrangement depends on:
The dimensions of one block should not be treated as a universal safe-working-load rating.
The correct support block should not be selected only according to the total machine weight or maximum crane capacity.
Important selection information includes:
Each support position should be evaluated independently because reactions and supporting conditions can differ around the same machine.
A long-strip support block may be used individually or as one component of an approved modular support arrangement.
A single block may be suitable where:
A multi-block arrangement may be considered where additional support area or height is required.
When several blocks are used, the arrangement should consider:
A narrow stack should not be built to excessive height without a suitable engineering assessment.
The supplied product information also lists square UHMWPE or HDPE outrigger pads. Selected dimensional references include:

UHMWPE HDPE Outrigger Blocks can be considered for a variety of equipment-support operations.
The correct block dimensions, quantity, material, orientation and support arrangement should always be matched to the actual operating requirement.
Reusable support blocks should be inspected before every demanding equipment-support operation.
Check:
A damaged block should be removed from demanding service and evaluated before reuse.
After operation, remove mud, sand, gravel, oil and other contaminants from the support surfaces and carrying holes.
