Lightweight, Compact, Low-friction, Certified

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.

Simple to Use in Load-assist Applications

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 are also used to transfer loads in deviation, and to take the load when lifting inanimate objects.

Maintenance is Easy

To clean, simply flush pulleys with fresh water. 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.
