Low-friction Sheave

Delrin® ball bearings provide low-friction, easy rope release under load. Ball bearings are UV-stabilized for maximum protection. Delrin is a registered trademark of E.I duPont de Nemours and Company or its affiliates.

Ball Bearing Cam Cleats

Harken ball bearing cam cleats hold rope securely and release easily under load. Multiple rows of ball bearings reduce friction. The cam’s V-shape guides rope for easy entry.

Tamper Evident

Purchase systems are supplied pre-reeved and fully assembled. The securing knot is sealed to prevent irreparable damage to the system.

Polyester Rope and Safety Compliance

Purchase systems use polyester based rope in various sizes. The polyester braided covers are UV and abrasion resistant. Harken Industrial purchase systems are also serial numbered for full traceability.

Harken Industrial™ purchase systems increase operation strength, providing low-friction pulling power in a wide variety of pulling/lifting operations. Systems can be used on their own, or easily combined with an existing system for tensioning, deviation, or casualty transfer. Purchase systems come fully rigged with tamper-evident termination. Harken Industrial purchase systems are used by emergency services and rescue personnel to help transfer loads and individuals from working ropes to alternates. The systems also are used to transfer loads in deviation, and to take the load when lifting inanimate objects. To clean, simply flush pulleys with fresh water. Periodically soaking in fresh water is recommended when used in a marine environment to prevent salt crystal growth. As with all equipment, check regularly to make sure it is in good working order. Check rope for chafe and wear. Make sure tamper-evident seals are intact. The IN2624 purchase system can be used for human suspension when a safety factor of 10 is applied and used in conjunction with fall protection, in accordance with local standards and regulations. Available in multiple lengths for various range of travel from 1 to 40 m.
