Features:

• Slim Design: Narrow drive cylinder housing matches the ratchet link width, ideal for tight spaces and applications with protruding threads or limited clearance above nuts/bolts.
• Dual Piston System: Increases speed with higher effective rotational speeds per stroke.
• Reaction Pawl: Ensures consistent angular rotation for enhanced efficiency.
• 360° x 120° Uni-Swivel: Allows flexible hose positioning for safe and convenient adjustments.
• Integrated Reaction-Free Links: Eliminates kickback for smoother, safer torque application.
• Hands-Free Operation: Optional tool retainer enables hands-free bolting, reducing operator risk.
• Quick Couplers: Simplifies connections for efficient bolting operations.
• Torque and Angle Control: Supports precise torque and angle adjustments.
• Subsea Compatibility: Operates effectively in subsea environments.
• ATEX Certified: Some models are ATEX-compatible for hazardous environments.
• Compatibility: Works with HYTORC Washer, HYTORC Nut, and robotic bolting systems for seamless integration.

Accessories:

• HYTORC Washer Retainer: Enables hands-free operation and eliminates the need for a separate reaction fixture.
• ALCO Arm: Supports hands-free bolting.
• HYTORC Nut Driver: Converts torque into tension, preventing galling.
• Reaction Plate Kits: Various reaction fixtures for diverse bolting needs.
• Square Drive Conversion Link: Available for use with hex and Allen sockets.

Applications: Ideal for low-clearance bolting in industries such as oil and gas, power generation, aerospace, and subsea operations.

Notes:

• Requires a calibrated pressure/torque chart for standard ratchet links, compliant with VDI 2230 standards.
• Maximum operating pressure: 690 bar (10,000 psi).
• Calibration certificate provided.
• Maintenance recommended by HYTORC, with preventive maintenance guidelines in the operational manual.
• Use with HYTORC-approved hydraulic hoses (700 bar working pressure, safety factor of 4) and pump units.
• For specific hex link sizes, refer to HYTORC’s documentation (e.g., links 1–13 cover sizes from 1 7/16" to 3 3/4").
