Su-7 Drill powered pulley for Working at Heights, Rope Climbing & Outdoor Use
Product Description:
The Arakno SU-7 is a professional electric ascender/descender designed as a drill powered pulley for lifting, lowering, and working at height. Powered by a standard electric drill via a hexagonal drive connection, this drill powered pulley system provides efficient, controlled rope movement for rescue, rope access, and material handling applications.

Precautions for Use:
Use only with double-rope (DRT) operation when operating this drill powered pulley.
Before first use, soak a new rope in water and run it through the lowering device several times before using the electric lifting function.
If the pulley and rope become hot during operation, prepare water and apply it to the pulley and rope promptly to reduce heat buildup.
Regularly inspect the lubrication of the gearbox and apply high-viscosity, high-temperature-resistant lubricating grease as required.
If the four-axis roller becomes stuck or does not rotate smoothly, clean off dust immediately or apply a rust inhibitor.
Applications:
This drill powered pulley is suitable for lifting loads and working at heights, including rope rescue, maintenance at height, and rope access operations.
The device can be integrated into rope rescue systems to increase pulley set efficiency, as it is equipped with a built-in labor-saving mechanism.
The system uses an electric hand drill and a hexagonal connecting rod to drive the gearbox shaft clockwise. Increasing the input power increases operating speed.
This drill powered pulley system must not be used in corrosive environments, as chemical reactions may damage materials, impair functionality, or reduce product lifespan.
Designed for use in dry environments only. The device is neither waterproof nor dustproof and should be cleaned and stored properly after use to extend service life.
The use of rotary impact wrenches or electric hammers as a power source is strictly prohibited.
Gear oil or grease may be used as lubricants. A timing test result of “No” is considered normal.
