Holloway Houston Grommet Wire Rope Slings
Holloway Houston High-Capacity Low-Headroom Cable Grommets are designed for lifting operations where space is limited but load strength is critical. These wire rope grommets are designed as continuous loops, giving them the flexibility and strength required in heavy-duty lifting applications. Commonly used across industries such as manufacturing, construction, oil and gas, and utilities, these grommets support efficient lifting even in compact or low-clearance environments.
About Holloway Houston High-Capacity Low-Headroom Grommets
Each Holloway wire loop slings (grommets) is made as a continuous loop of high-strength wire rope that can be mechanically joined or swaged. This seamless design provides flexibility and allows shorter circumferences compared to traditional wire rope slings. Available in diameters in different ranging from 1.50” to 6” and lengths up to 22 feet, they accommodate diverse lifting needs.
Key Features
- Continuous loop design for balanced load handling.
- Available in various diameters and lengths (1.50” to 6”).
- Extra Improved Plow (EIP) steel for added strength.
- Independent Wire Rope Core (IWRC) for higher load support.
- Compatible with vertical, basket, and choker hitches.
- Adaptable to low-headroom lifting environments.
- Easy integration with lifting accessories such as shackles, master links, and hooks.
Lifting Configurations of Wire Rope Grommets
Depending on the application, the same Holloway endless wire rope grommets can be used in several configurations to achieve different lifting results
Vertical Hitch
Used for straight vertical lifts where the load is directly under the hook. Suitable for single-point lifting where alignment is crucial.
Choker Hitch
Used when the load needs to be tightened or stabilized. Common in applications where cargo must remain snug during lifting or transport.
Basket Hitch
Provides the highest rated capacity by distributing the load evenly across the grommet. Ideal for symmetrical lifts.
Technical Specifications of Grommet Wire Rope Slings
Holloway Houston High-Capacity Grommets are available in multiple capacities, depending on rope diameter and configuration. The rated capacities typically vary from 1.1 tons to over 71 tons, depending on hitch type:
| Rope Diameter (inches) | Vertical (tons) | Choker (tons) | Basket (tons) |
|---|---|---|---|
| 0.25 | 1.1 | 0.7 | 2.1 |
| 0.50 | 4.1 | 2.9 | 8.3 |
| 1.00 | 16.0 | 11.0 | 32.0 |
| 1.50 | 36.0 | 25.0 | 71.0 |
Note : Capacities are based on a curvature diameter of five times the individual rope diameter at the points of load contact.
