Jack Blocks for Equipment Support
Stable, lightweight foundations for heavy equipment installations
What are Jack Blocks?
Jack blocks are weight-bearing support platforms designed to provide stable foundations for equipment installations and load distribution. They safely support heavy loads during lifting operations, equipment placement, and long-term installations.
Traditional options include wood cribbing (prone to splintering and rot), rubber blocks (heavy and vulnerable to oil degradation), and concrete (extremely heavy and difficult to handle). Modern polypropylene jack blocks deliver superior load capacity at a fraction of the weight – enabling safer, more efficient installations.

Commercial applications requiring different dimensions can request custom sizing to meet specific project requirements.
Why Polypropylene Outperforms Traditional Materials
Versus Wood Cribbing: Wood splinters, rots, absorbs moisture, and loses strength over time. Polypropylene maintains structural integrity regardless of weather exposure and won’t degrade from ground contact.
Versus Rubber Blocks: Rubber blocks are heavy, bulky, and break down when exposed to oils and fuels. Polypropylene delivers superior load capacity at a fraction of the weight while resisting chemical degradation.
Key Performance Advantages:
- Waterproof construction eliminates moisture absorption and rot
- Non-conductive properties provide electrical safety
- Chemical resistance withstands exposure to oils, fuels, and environmental elements
- Temperature stability maintains performance across wide temperature ranges
- No cracking, warping, or long-term creep ensures reliable long-term performance
- Tremendous load capacity at only 7.5 lb per block
Installation Benefits
Single-Person Handling
At just 7.5 lb, Power Pad jack blocks eliminate the physical strain and multi-person requirements of wood cribbing or heavy rubber alternatives.
Even Weight Distribution
Engineered geometry distributes loads uniformly across the support surface for superior stability.
Versatile Placement
Lightweight construction enables precise positioning without heavy lifting equipment, reducing installation time and labor costs.
Safe for All Weather
Non-absorbent, waterproof material performs consistently in wet, frozen, or high-temperature conditions.
Commercial-Grade Reliability
Power Pad jack blocks are engineered for professional applications where reliability matters:
- Proven load capacity tested to 37,000 lb uniform load
- Chemical resistance for industrial environments with fuel and oil exposure
- Non-conductive construction for electrical safety
- Custom sizing available for specialized commercial requirements
- Long-term durability without the deterioration of wood or rubber
Selection Criteria
Load Requirements
Verify your application falls within the 37,000 lb @ 23℃ or 26,000 lb @ 50℃ capacity range for standard blocks.
Environmental Conditions
Consider exposure to chemicals, moisture, temperature extremes, and electrical hazards when selecting support materials. Power Pad jack blocks are chemical resistant, waterproof, temperature-tolerant, and non-conductive.
Installation Logistics
Single-person handling capability reduces labor costs and injury risk compared to heavy traditional alternatives.
