Crane Pads Tensile Strength



The tensile strength of Crane Pads is an important indicator of its tensile strength, which determines its stability and durability under high loads. Crane Pads made of different materials have different tensile strengths. Common materials are as follows:

1. Tensile Strength of Common Materials

MaterialTensile Strength (MPa)Description
UHMWPE (Ultra High Molecular Weight Polyethylene)20-40High wear resistance, impact resistance, low friction coefficient
HDPE (High Density Polyethylene)25-40Chemical corrosion resistance, high strength
Rubber (Reinforced Rubber)10-20Elastic, suitable for absorbing impact
Composite Pads50-80Made of glass fiber reinforced plastic or other high-strength composite materials, high strength and durability
Steel Crane Pads250-400Highest strength, but heavy and not easy to move

2. Tensile Strength of UHMWPE Crane Pads

The tensile strength of UHMWPE is generally 20-40 MPa, which may vary depending on the specific formula and additive content.

Factors affecting tensile strength:

Molecular weight: The higher the molecular weight, the stronger the tensile resistance, but the processing difficulty increases.

Additives: Carbon black filling can improve UV resistance, but has little effect on tensile strength.

Temperature: UHMWPE maintains good toughness at low temperatures, while high temperatures may reduce strength.

3. Crane Pads Selection Notes

For heavy cranes, composite or high-density UHMWPE Crane Pads are recommended to ensure sufficient tensile strength and compressive resistance.

For small and medium-sized lifting equipment, HDPE or UHMWPE are economical and durable choices.

If higher strength is required, glass fiber reinforced composite or steel Crane Pads can be selected.
