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

Description

Corrosion Resistant Chain Block for Marine & Offshore Lifting

The Tiger SS20 Corrosion Resistant Chain Block from Tiger Lifting is engineered specifically for demanding lifting operations in marine, offshore, coastal, and harsh industrial environments where corrosion resistance and operational reliability are critical.

Manufactured in Tiger’s ISO9001-certified facility using precision-machined high-strength steel, this heavy-duty manual chain hoist combines rugged durability with advanced corrosion protection technology to deliver dependable lifting performance in saltwater, high-humidity, and exposed outdoor environments.

Its compact low-headroom design makes it ideal for restricted spaces, offshore platforms, shipyards, docks, marine maintenance operations, and coastal infrastructure projects.

Corrosion Resistant Load Chain for Harsh Environments

At the core of the SS20 is Tiger’s specially treated corrosion resistant load chain, manufactured to Grade T/VH standards and compliant with EN818-7 and ISO 16872.

Unlike conventional load chain finishes, this advanced chain treatment provides:

• Superior resistance to oxidation and surface corrosion
• Excellent tensile strength and durability
• Reliable operation in saltwater and marine conditions
• Long service life in offshore environments

This makes the SS20 particularly suitable for:

• Marine deck lifting
• Offshore maintenance operations
• Dockside lifting applications
• Shipbuilding and repair facilities
• Multi-immersion lifting tasks

Advanced C5M Corrosion Protection System

The SS20 chain block incorporates Tiger’s specialist C5M-grade corrosion protection system in accordance with ISO 12944, delivering exceptional protection against aggressive environmental exposure.

Key corrosion-resistant features include:

• Two-layer electroplated and powder-coated protective finish
• Phosphor-bronze bearings for superior marine wear resistance
• Stainless steel fasteners and fittings throughout critical assemblies
• Corrosion-protected internal components for long-term reliability
• Bonded marine friction discs designed for wet and submerged operation

This protection system ensures extended operational life in environments where standard lifting equipment would rapidly deteriorate.

Bonded Marine Friction Discs for Wet & Submerged Use

The SS20 features advanced bonded marine friction discs specifically developed for wet and marine lifting environments.

The grooved disc design disperses water efficiently, preventing aquaplaning, which can reduce braking friction in submerged or high-moisture conditions.

This ensures:

• Safe and controlled lifting and lowering
• Reliable braking performance in wet conditions
• Improved operational safety offshore and subsea

Patented Quad Cam Brake System for Maximum Safety

The Tiger SS20 range incorporates the patented Quad Cam Pawl Brake System, delivering superior safety compared to traditional twin-pawl chain blocks.

This advanced design guarantees that at least one pawl remains permanently engaged during operation. Even in the unlikely event of a spring failure, the brake remains fully operational.

Additional safety advantages include:

• Faster brake engagement response
• Precise load control
• Enhanced load-holding performance
• Safe operation during lifting and lowering

The integrated 8-point multi-start pinion shaft improves brake responsiveness by up to 100% over conventional 4-point systems.

Designed for Angled & Offshore Lifting Applications

The SS20 can safely perform:

• Fleeting operations
• Drifting lifts
• Cross-hauling applications

at angles up to 60° from vertical without deration, making it highly effective for offshore and marine lifting tasks where vertical lifting is not always possible.

The EZ Check hook system allows operators to quickly identify signs of previous overload conditions, improving inspection efficiency and operational safety.

Optional Overload Protection System

For enhanced lifting safety, the SS20 can be fitted with an optional slipping clutch overload limiter, verified by DNV GL to NORSOK R-002 standards.

When overloaded, the clutch automatically slips to prevent dangerous over-lifting while still allowing safe lowering of the load.

This helps protect:

• Operators
• Suspended loads
• Lifting equipment
• Structural support systems

from overload damage.

Multi-Immersion Tested for Offshore Reliability

The SS20 has undergone extensive environmental and corrosion testing for offshore and marine use.

Performance testing includes:

• Verified for up to 54 days of saltwater exposure
• Multi-immersion application testing
• Over 1500 hours ASTM B117 salt spray testing
• Continuous cyclic testing exceeding 1500 cycles

The hoist operates reliably between –40°C and +80°C, with an optional low-temperature version available for operation down to –60°C.

Fully Tested & Certified to International Standards

Each Tiger SS20 chain block undergoes comprehensive testing prior to dispatch, including:

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

All units are supplied complete with:

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

Ideal for Marine, Offshore & Coastal Industries

The Tiger SS20 corrosion resistant chain block is trusted across industries including:

• Offshore oil & gas
• Marine engineering and shipyards
• Ports and dockside operations
• Coastal infrastructure maintenance
• Renewable energy installations
• Heavy industrial maintenance

Its combination of advanced corrosion protection, offshore safety systems, and marine-grade durability makes it one of the leading manual chain hoists for harsh environment lifting operations.
