Available Configurations
Eye & Eye HMPE Slings
Reinforced eye terminations for vertical, choker, or basket hitches. Protected splices with abrasion-resistant sleeves or thimbles. Standard lengths from 3–40 meters.
Endless Grommet HMPE Slings
Continuous loop for maximum versatility. Uniform load distribution with multiple attachment orientations. Ideal for rotation-sensitive lifts.
Hammerhead Slings
Compact eye geometry for confined rigging spaces. Full capacity retention with reduced eye projection. Designed for subsea structures and modular connections.
High-Modulus Polyethylene Lifting Slings
HMPE (High-Modulus Polyethylene) slings deliver exceptional lifting capacity at approximately one-eighth the weight of wire rope. The one-eighth figure reflects material-basis comparisons (HMPE vs steel); final sling capacity depends on construction and terminations. Manufactured at Holloway Houston’s facility using ultra-high molecular weight polyethylene fibers, these slings provide low elongation, enhanced cut resistance with proper edge protection, and proven performance in offshore and industrial applications.
About High-Modulus Polyethylene Lifting Slings
Each Holloway HMPE sling is proof-tested to 2× Working Load Limit as part of our quality program (HHI practice), with full certification documentation. Working Load Limits are established per manufacturer data; confirm final selection against application requirements, D/d ratios, and sling angles measured from horizontal.
Key Features
- Weight Reduction : Approximately 85–90% lighter than wire rope of equal capacity by material basis; verify per Holloway Houston spec.
- Low Elongation : Maintains precise load control during lifts.
- 5:1 Design Factor : Manufactured to OSHA 1910.184 and ASME B30.9 (latest edition) .
- Houston Manufacturing : Fabricated and tested at our Houston facility.
- Proof-Test Certified : Every sling tested at 2× WLL with documentation (Holloway Houston practice).
Specifications
Fiber Type : Ultra-high molecular weight polyethylene (UHMWPE)
Specific Gravity : 0.97 (floats in water)
Temperature Limits : Per Holloway data sheet for the specified construction
UV Protection : Standard protective coating on all slings
Chemical Resistance : Generally resistant to acids, alkalis, hydrocarbons; verify media, concentration, and temperature
Note : Working Load Limits depend on construction, D/d ratios, and sling angles measured from horizontal. For exact WLLs, request the dated Holloway Houston capacity chart (doc ID, rev/date) or see the Type B Technical Reference.
Performance Characteristics
Weight Advantage : Approximately 85–90% lighter than wire rope of comparable capacity, reducing hook load and simplifying handling.
Safety : Lower mass versus steel rigging reduces stored energy; however, failure behavior depends on system geometry and loading. Maintain exclusion zones and follow OSHA/ASME inspection practices.
Marine Environment Performance : HMPE fibers do not rust. Service life depends on UV exposure, temperature, abrasion, and loading history. Use appropriate covers and edge protection; inspect per OSHA/ASME.
Load Control : Low elongation helps maintain precise load positioning—useful for modular installations and subsea placement.

Inspection & Tagging
- OSHA 1910.184 and ASME B30.9 require regular inspection by a competent person.
- Refer to applicable Holloway Houston data sheet and ASME B30.9 for HMPE sling removal criteria.
- Maintain inspection records per OSHA/ASME requirements.
Refer to the applicable Holloway houston data sheet and ASME B30.9 for HMPE sling removal criteria. Maintain inspection records per OSHA/ASME.
Remove from Service If :
Cuts, snags, or abrasion that expose or sever load-bearing fibers.
Heat/chemical damage (glazing, hardening, melting, charring, or notable discoloration).
Deformed, damaged, or opened splices/terminations; damaged protective covers.
Unknown/questionable history, unreadable/absent identification, or suspected overload.
Documentation & Compliance
Every Holloway HMPE Sling Includes :
- Proof test certificate at 2× WLL (Holloway Houston practice).
- Unique serial number with QR code.
- ASME B30.9 compliance documentation.
- Inspection and retirement guidelines per OSHA 1910.184.
- Multi-leg assembly charts with angles from horizontal (vertical = 1.0, choker = 0.80, basket = 2.0).

Typically higher strength-to-weight and lower elongation for a given diameter, subject to construction. See Holloway specifications.
With proper inspection and care, service life varies by environment and usage. Regular inspection and proper storage extend service life.
Often possible, subject to D/d ratios, hardware fit, temperature limits, edge protection, and angle effects. Holloway engineering will validate suitability.
Every sling is proof-loaded at 2× WLL on our calibrated test bed (HHI practice). Certificates include date, serial number, actual test load, and technician verification
All angles are measured from horizontal. A vertical sling is 90° from horizontal.
Yes—custom lengths, capacities, and multi-leg assemblies per project requirements.
Follow the D/d limits specified in the Holloway data sheet for the sling construction and termination. Smaller D/d reduces strength retention; provide pin diameters and hardware specs when requesting quotes.
