Product Description

S.W.L:0.5-10 Ton

The CY Type Single Sheave Snatch Block is engineered to facilitate demanding lifting and pulling operations. Designed as an easy-to-use, versatile manual lifting equipment, it serves as a critical component in factories, mines, agricultural production, building construction, dock ships, warehouses, machine installation, and general cargo lifting. Featuring a secure hook type configuration, this block allows operators to quickly insert or remove wire ropes without threading them from the end, significantly reducing setup time on active work sites.

With a certified Safe Working Load (S.W.L) ranging from 0.5 to 10 Ton, it delivers reliable mechanical advantage for heavy-duty rigging. The single sheave mechanism rotates smoothly under maximum tension, minimizing friction and extending the lifespan of your steel cables. Whether you are managing marine rigging tasks in salt-heavy coastal environments or hoisting materials on a dusty construction site, the solid metallic heft and precise engineering of this snatch block provide operators with absolute confidence. The quick-release side plate mechanism clicks firmly into place, offering tactile assurance that the load is securely locked before any lifting commences.

Specification

To ensure operational safety and longevity, our snatch blocks are manufactured using hardened, wear-resistant steel alloys. The exterior undergoes a specialized anti-corrosion surface treatment, leaving a smooth, industrial-grade finish that resists rust even when exposed to harsh marine elements or abrasive outdoor conditions. This meticulous coating process not only protects the structural integrity of the pulley but also prevents premature degradation in demanding industrial sectors.

Every unit is backed by a rigorous quality control system. Before leaving the facility, the blocks are subjected to standardized tension testing to verify their structural limits. This ensures that the 0.5-10 Ton S.W.L rating is strictly adhered to, complying with international lifting and rigging safety protocols. The heavy-duty drop-forged hook is equipped with a spring-loaded safety latch, which snaps shut with a definitive metallic click, preventing accidental rope disengagement during dynamic lifts.

Our Snatch Blocks

We understand that different project sites require specific rigging solutions. Therefore, our manufacturing facility offers flexible OEM and ODM production services tailored to your procurement requirements. We support custom specifications, including specialized sheave diameters, distinct brand markings, and tailored packaging solutions designed for bulk distribution.

When you handle these snatch blocks, the balanced weight distribution and precisely machined grooves immediately convey their industrial reliability. The single sheave design is optimized to prevent wire rope twisting, ensuring a straight, controlled pull every time. By integrating these units into your daily operations, you can expect fewer equipment changeovers and a noticeable improvement in overall workflow efficiency.

Operational Advantages and Maintenance

The intuitive side-opening mechanism is a standout feature for field operators. Instead of threading a long, heavy cable through a closed loop, the user simply unpins the side plate, swings it open, lays the cable over the sheave, and locks it back into place. This tactile, tool-free process takes only seconds and drastically reduces the physical strain on your crew. Furthermore, the central bearing is designed for low maintenance, requiring only periodic lubrication to maintain its silent, frictionless rotation under heavy loads.

Mechanical Advantage in Rigging Systems

A snatch block can also form part of a reeved wire rope system.

Depending on how the rope is anchored and routed, pulley arrangements can change the relationship between required pulling force and load movement.

A multi-part system may reduce the input line pull required for a particular load, but it also changes the forces acting on individual rigging components.

Components That Must Be Rated Together

When creating a mechanical-advantage system, check the capacities of:

• Snatch blocks

• Wire rope

• Hooks

• Shackles

• Slings

• Winches

• Pullers

• Anchor points

• Supporting structures

The capacity of the complete system is limited by its lowest-rated component.

For heavier rigging requirements, SUPER FISHER also supplies the Heavy Duty MLS Snatch Block with Shackle, 2–85 Ton SWL.

Core Application Environments

• Marine and Dock Operations: The anti-corrosive properties make these blocks ideal for ship docking, cargo loading, and offshore rigging tasks where saltwater exposure is a constant challenge.

• Construction and Architecture: Essential for hoisting structural materials, guiding winch cables, and facilitating heavy machinery installation on multi-story building sites.

• Mining and Extraction: Built to withstand abrasive dust and heavy impacts, providing reliable pulling power for extracting materials and positioning heavy equipment underground.

• Agricultural and Forestry Work: Highly effective for land clearing, pulling heavy timber, and tensioning large-scale agricultural netting systems.

CY Single Sheave vs Double Sheave Snatch Block

The number of sheaves affects how the block can be incorporated into a rigging arrangement.

Single Sheave Snatch Block

A single sheave is suitable when:

• One rope path needs to be redirected.

• A simple pulley arrangement is required.

• Compact size is preferred.

• The rigging system does not require multiple rope falls through the same block.

Double Sheave Snatch Block

A double sheave design may be preferred when:

• More complex reeving is required.

• Multiple rope parts need to pass through the same block.

• The rigging design calls for additional mechanical advantage.

SUPER FISHER also supplies CY Type Double Sheave Snatch Blocks for applicable rigging arrangements.

The correct configuration depends on the system design rather than simply choosing the block with more sheaves.

Choosing the Correct CY Snatch Block

Several factors should be checked before selecting a model.

Required Safe Working Load

Calculate the actual load that will act on the block.

Do not select capacity based only on load weight or winch pulling force.

Wire Rope Diameter

Confirm that the wire rope is compatible with the sheave groove.

The rope should sit correctly without excessive clearance or pinching.

Sheave Diameter

The sheave diameter should be suitable for the selected wire rope and required bending conditions.

Hook Connection

Confirm that the hook can connect correctly to the intended anchor.

The connection must sit in the hook bowl rather than bearing on the tip or latch.

Working Environment

Consider whether the equipment will be used in:

• Indoor factories

• Construction sites

• Mines

• Outdoor yards

• Marine environments

• Dusty areas

• Wet conditions

Environmental conditions affect inspection and maintenance frequency.

Commitment to Rigging Excellence

By prioritizing both material strength and user-centric design, this single sheave snatch block stands as a dependable asset for any heavy-duty lifting portfolio. The forged hook provides a secure anchor point that adapts to various slings, chains, and shackles, while the precisely contoured sheave groove prevents cable flattening. Whether you are outfitting a commercial shipping fleet or upgrading the rigging hardware for a national construction firm, these blocks deliver the consistent, secure performance required to keep your projects moving safely and efficiently.
