Tiger PROCB14 Professional Chain Block – 250kg-35t WLL

Description

Professional Manual Chain Block for Demanding Lifting Applications

The Tiger PROCB14 Professional Chain Block is engineered for operators who require exceptional safety, durability, and smooth lifting performance in demanding environments. Designed using precision-machined premium-grade steel components, the PROCB14 combines lightweight handling with rugged construction, making it ideal for industrial lifting, heavy engineering, offshore operations, construction sites, workshops, fabrication facilities, and shipyards.

Built to withstand intensive daily use, the PROCB14 offers dependable manual lifting performance with reduced operator effort, precise load control, and long-term reliability across a wide range of lifting applications.

Available in capacities from 250kg up to 35 tonnes, the Tiger PROCB14 delivers professional-grade lifting performance for both light-duty and heavy-duty operations.

Patented Quad Cam Pawl Brake System for Enhanced Safety

At the core of the PROCB14 is Tiger’s patented Quad Cam Pawl System, an advanced braking mechanism designed to maximise operational safety and load security.

Unlike conventional chain blocks, the Quad Cam system ensures that at least one of the reciprocating pawls remains permanently engaged with the ratchet wheel at all times. This means the load remains securely held even in the unlikely event of pawl spring failure.

This innovative design exceeds the requirements of BS 4898:1973 and provides superior protection during lifting, lowering, and load-holding operations.

Key safety advantages include:

• Continuous brake engagement
• Improved load security
• Enhanced reliability under heavy use
• Safer lifting in demanding environments
• Reduced risk of accidental load release

Smooth Low-Effort Operation with Advanced Gear Design

The PROCB14 incorporates Tiger’s 8-point multi-start pinion shaft, delivering significantly improved brake responsiveness and efficiency compared with traditional 4-point systems.

This advanced gearing arrangement provides:

• Faster brake engagement
• Smoother load transitions
• Reduced hand chain effort
• Improved lifting control
• Enhanced operational precision

The result is a professional chain block capable of smooth, controlled lifting with minimal operator fatigue, even during repetitive lifting cycles or heavy-duty operations.

Heavy-Duty Alloy Load Chain for Maximum Durability

Each Tiger PROCB14 is fitted with high-strength Grade T or VH alloy steel load chain manufactured in accordance with EN818-7 and ISO 16872 standards.

The precision-calibrated chain provides:

• Exceptional tensile strength
• Long-term wear resistance
• Reliable load handling
• Smooth chain movement
• Excellent durability under repeated use

For corrosive or marine environments, stainless steel load chain options are also available.

Optional Overload Protection System

For enhanced operational safety, the PROCB14 can be supplied with an optional slipping clutch overload limiter.

When the rated capacity is exceeded, the overload clutch slips automatically to prevent further lifting while still allowing the load to be safely lowered under full control.

This advanced protection system has been DNV GL Verification tested to NORSOK R-002 standards, making it ideal for demanding industrial and offshore lifting operations.

Benefits include:

• Protection against overloading
• Reduced risk of equipment damage
• Enhanced operator safety
• Improved gearbox protection
• Controlled lowering during overload situations

Low Headroom Design for Restricted Spaces

The compact low-headroom construction allows the PROCB14 to operate effectively in confined spaces and restricted lifting areas where installation height is limited.

Combined with its lightweight yet robust steel body, the hoist is ideal for:

• Maintenance operations
• Plant rooms
• Structural steelwork
• Offshore platforms
• Shipbuilding
• Industrial assembly areas
• Construction projects

The deep-profile hand wheel also improves chain tracking and smooth chain feed during operation.

EZ Check Hooks for Quick Safety Inspection

Tiger’s patented EZ Check hooks are fitted as standard across the PROCB14 range.

These drop-forged and heat-treated alloy hooks include integrated overload indicators that allow operators and inspectors to quickly determine whether the hoist has experienced shock loading or overload conditions.

The heavy-duty safety latches fully engage into the hook nose to provide secure load retention during lifting operations.

Engineered to International Lifting Standards

The Tiger PROCB14 Professional Chain Block is fully certified and manufactured in compliance with major international lifting standards, including:

• BS EN 13157:2004+A1:2009
• ANSI/ASME B30.16
• AS 1418.2
• SANS 1594
• Machinery Directive 2006/42/EC

Each unit is supplied complete with:

• Test Certificate
• EC Declaration of Conformity
• Operating instructions
• Identification markings and traceability

Extensive Testing & Quality Assurance

Every PROCB14 undergoes comprehensive testing and inspection prior to dispatch, including:

• Proof load testing at 1.5 × WLL
• Ultimate strength testing at 4 × WLL
• Chain anchorage testing at 2.5 × WLL
• Continuous cyclic testing exceeding 1,500 cycles
• Light load testing at 2% of rated capacity

These rigorous testing procedures ensure consistent performance, reliability, and safety across the entire range.

Suitable for Industrial, Offshore & Construction Applications

The Tiger PROCB14 is widely used across multiple industries, including:

• Construction and infrastructure
• Offshore and marine operations
• Manufacturing and engineering
• Shipyards and ports
• Utilities and energy sectors
• Heavy industrial maintenance
• Warehousing and logistics
• Steel fabrication plants

Its combination of advanced safety systems, smooth operation, and rugged durability makes it one of the leading professional manual chain blocks available for heavy-duty lifting applications.
