FUDJUR-FJ sliding direct-drive fall arrester
📦Product Name: FUDJUR Sliding Fall Arrestor
Model: FJ59157
🌟Key Product Highlights
🛡️Dual International Certifications, Guaranteed Safety
The product is designed and manufactured in strict accordance with international standards, ensuring quality:
EN353-2:2002: EU fall arrest standard, applicable to flexible guide rail systems
EN12841:2006 Class A: EU rope technology equipment standard, Class A fall arrest function certification
Applicable rope diameter: 9-13mm, covering mainstream rope specifications
🔄Friction-based fall arrest, gentle rope protection
Unlike traditional ratchet-type fall arresters, this product uses the principle of friction to achieve fall arrest:
Ratchetless design: Does not cause puncture damage to the rope, significantly extending rope lifespan
Smooth sliding: Slides with the rope during normal operation, without affecting freedom of movement
Self-locking upon fall: In the event of a fall, friction increases instantaneously, automatically locking the rope
Minimally affected by debris: Mud, sand, water stains, etc. on the rope sheath do not easily affect fall arrest performance
⚡No energy absorber required, simplified system
Unique Friction-based design allows for direct use without the need for an additional energy absorber:
Simpler system: Reduced connection points lower the risk of malfunction
Lighter weight: No need for an additional energy pack; the entire device weighs only 168g
Lower cost: No need for regular energy absorber replacements, reducing overall operating costs
✈️Aerospace-grade materials, lightweight and high strength
Main body material: 7075 aerospace-grade aluminum alloy, CNC precision machined, high strength and lightweight
Sliding parts: Stainless steel wear-resistant plates ensure durable smoothness and reliable braking
Overall weight: Only 168g, extremely lightweight, comfortable for extended wear
📐Compact size, portable
Size: 11.5" × 7 × 3 cm, compact and unobtrusive, won't get in the way or snag.
Two-way markings: The product surface is clearly marked with UP (ascending) and GO (sliding) directions to prevent misuse.
Batch traceability: Production batch 25HM, quality traceable.

🛠️Product Structure Diagram
Components | Function
Aluminum alloy main body: Lightweight and high strength, CNC precision machining
Stainless steel friction plate: Provides fall-stopping friction, wear-resistant and corrosion-resistant
Rope channel: Compatible with 9-13mm ropes
Direction markings: UP (ascending) / GO (sliding) to prevent misuse
Connecting hole Connecting to safety harnesses or work positioning systems
🎯Applicable Scenarios and System Combinations
Scenario | Application Method
High-altitude operations | As the main fall arrestor, moving up and down with the worker
Rope technology | Used in conjunction with a work positioning system for double protection
Wind power operation and maintenance | Climbing and work protection inside wind turbine towers
Tree pruning | Fall protection during tree climbing operations
Fire and rescue Fall Protection During Vertical Ascent
Typical System Configuration:
Main Rope: Connects to the sliding fall arrester, providing full fall protection.
Working Rope: Connects to the descender or ascender for operational use.
Dual Rope System: One rope for safety and one for operation, balancing safety and efficiency.
🔄Working Principle Diagram
During Normal Ascent/Descent:
The fall arrester slides freely with the rope, not affecting operational movements.
The friction plate makes slight contact with the rope sheath, providing only guidance.
During a Fall:
The instantaneous impact causes the fall arrester to tilt and lock.
The friction increases sharply, firmly locking it to the rope.
No energy absorber required; it directly absorbs the kinetic energy of the fall.
⚙️Comparison with Ratchet Fall Arresters
Comparison Items: FUDJUR FJ59157 Traditional Ratchet Fall Arrester
Role Grip Principle: Friction Locks, Ratchet Pierces
Rope Wear: Minimal, Significant, Easily Damages Rope Core
Energy Absorber: No External Connection Required, Usually Required
Affected by Debris: Less, Significant, Mud and Sand Easily Get Stuck in Teeth
Weight: 168g Typically weighs 200g+
🎯Suitable for:
High-altitude workers: Exterior wall cleaning, curtain wall installation, wind power maintenance
Rope rescue team members: Mountain rescue, urban search and rescue
Industrial safety inspectors: Tower inspection, bridge inspection
Tree climbers/caving enthusiasts: Safety protection during vertical activities
Safety training instructors: Fall arrest system demonstration
⚠️Usage Tips
Compatible Ropes: Only suitable for ropes with a diameter of 9-13mm. Do not mix and match.
Correct Direction: Check the UP/GO direction markings before use to prevent reverse installation failure.
Professional Training: Please receive professional fall arrest system training before use.
Regular Inspection: Check the friction pads for wear and the main body for deformation before each use.
No Modification: Do not disassemble or modify the product structure yourself.
Usage with Recommended Equipment: Recommended for use with standard safety harnesses, carabiners, etc.
✨Conclusion: FUDJUR FJ59157 Sliding Fall Arrestor: No ratchet teeth, better rope protection; no energy pack, simpler design.
Dual certification, lightweight and portable. Safe 2 Explore, protecting every vertical exploration.
