Tiger SS20 Corrosion-Resistant Chain Block (Steel Chain) – 500kg-30t WLL

Description

Heavy-Duty Corrosion Resistant Chain Block for Offshore & Industrial Lifting

The Tiger SS20 Corrosion Resistant Chain Block with Steel Chain from Tiger Lifting is engineered to deliver exceptional lifting performance in demanding offshore, marine, coastal, and heavy industrial environments.

Combining advanced corrosion protection with high-strength alloy steel lifting components, this manual chain hoist provides the ideal solution for applications requiring both maximum load capacity and long-term durability in harsh operating conditions.

Manufactured using precision-engineered steel components and advanced protective coatings, the SS20 offers reliable operation in environments exposed to saltwater, moisture, abrasive contaminants, and extreme weather conditions.

High-Strength Steel Load Chain for Demanding Applications

The SS20 steel chain version features a precision-calibrated Grade T/VH alloy steel load chain, manufactured in accordance with EN818-7 and ISO 16872 standards.

This premium-quality steel chain delivers:

• Outstanding tensile strength and durability
• Reliable load handling under demanding conditions
• Excellent resistance to wear and fatigue
• Smooth operation during lifting and lowering

Available across a working load limit range from 500kg to 30 tonnes, the SS20 is suitable for both heavy industrial lifting and offshore load handling operations.

Advanced C5M Corrosion Protection System

To maximise operational life in aggressive environments, the SS20 incorporates Tiger’s specialist C5M corrosion protection system in accordance with ISO 12944.

The corrosion-resistant design includes:

• Electroplated base coating for superior adhesion and corrosion resistance
• Heavy-duty powder-coated outer finish with textured impact-resistant surface
• Stainless steel fasteners and fittings throughout exposed assemblies
• Internal anti-corrosion treatment for moving components
• Phosphor-bronze and DU® self-lubricating bearings for reduced wear and maintenance

This advanced protection system helps maintain long-term reliability in marine deck operations, shipyards, dockside environments, and offshore platforms.

Patented Quad Cam Brake System for Enhanced Safety

The Tiger SS20 range features the patented Quad Cam Pawl Brake System, engineered to provide superior load security and braking reliability.

This advanced system guarantees that at least one brake pawl remains engaged at all times, even in the unlikely event of a pawl spring failure.

Key safety benefits include:

• Continuous brake engagement
• Enhanced load control
• Faster brake response
• Increased operational safety during lifting and lowering

The integrated 8-point multi-start pinion shaft improves braking efficiency by up to 100% compared to conventional 4-point systems, ensuring smoother load handling and more responsive operation.

Bonded Marine Friction Discs for Wet Conditions

The SS20 steel chain hoist is equipped with bonded marine friction discs specifically designed for use in wet and marine environments.

The grooved friction disc design disperses water efficiently to prevent aquaplaning, maintaining consistent braking performance during:

• Saltwater lifting operations
• Offshore maintenance tasks
• Marine deck lifting
• Submerged or high-humidity applications

This ensures safe and controlled load handling even under challenging environmental conditions.

Designed for Angled & Offshore Lifting Operations

The Tiger SS20 can safely perform:

• Drifting operations
• Cross-hauling applications
• Fleeting lifts

at angles up to 60° from vertical without deration, making it highly effective for offshore and industrial environments where non-vertical lifting is common.

The deep-profile hand wheel ensures smooth chain feed while reducing the risk of chain twisting or snagging during angled lifting operations.

EZ Check Hooks & Optional Overload Protection

The SS20 includes EZ Check safety hooks, allowing operators and inspectors to quickly identify signs of previous overload conditions through simple visual inspection.

Additional hook features include:

• Drop-forged and heat-treated alloy hooks
• Heavy-duty spring latch kits
• Secure recessed hook nose engagement for improved load retention

For additional safety, the SS20 can be supplied with an optional slipping clutch overload limiter, independently verified by DNV GL in accordance with NORSOK R-002 standards.

The overload system prevents lifting beyond the rated capacity while still allowing safe lowering of the load.

Fully Tested & Certified for Professional Use

Every Tiger SS20 chain block undergoes extensive quality assurance and performance testing prior to dispatch.

Testing includes:

• Proof load testing at 1.5 × WLL
• Light load testing at 2% WLL
• Chain anchorage testing at 2.5 × WLL
• Continuous cyclic testing exceeding 1500 cycles
• Ultimate strength testing at 4 × WLL

Each unit is supplied complete with:

• Declaration of Conformity
• Full Test Certificate
• Machinery Directive 2006/42/EC certification

The SS20 also complies with:

• BS EN 13157:2004+A1:2009
• ANSI/ASME B30.16
• AS 1418.2
• SANS 1594

Ideal for Marine, Offshore & Heavy Industrial Applications

The Tiger SS20 corrosion resistant steel chain block is widely used across industries including:

• Offshore oil & gas
• Shipbuilding and marine engineering
• Ports and dockside operations
• Coastal infrastructure projects
• Heavy industrial lifting
• Renewable energy and offshore wind

Its combination of high-strength alloy steel chain, advanced corrosion protection, and offshore-rated safety systems makes it one of the most reliable manual chain hoists available for harsh environment lifting operations.
