Snatch Blocks
Mounting Block With Eye, Single With A Hinged Lid
A single sheave mounting block with eye and hinged lid, designed for secure attachment and controlled line redirection in lifting and rigging operations. The hinged lid allows quick cable entry and exit without removing the block from the mounting point. Available in load capacities from 0.5T to 20T with rope diameters ranging from 7.7mm to 35mm. The block model is HQG(L), with reinforced metal cheeks enclosing the pulley and a forged eye at the base for direct load attachment.

Key Benefits
What Mounting Block with Eye Gives You
- Hinged lid enables fast cable threading and unthreading without detaching the block from the mounting point
- Reinforced metal cheeks fully enclose the pulley to protect against debris and misalignment
- Forged eye at the base provides a strong, permanent attachment point for the load
- Single sheave design reduces pulling force and redirects hoist or winch lines efficiently
- Compact form factor fits in tight spaces on cranes, trailers, and marine decks
- Suitable for repeated use in dynamic lifting and towing applications with minimal maintenance
- Rope diameter range supports both synthetic and wire rope from 7.7mm to 35mm
Application Scenarios
Where Mounting Block with Eye Is Used
- Marine docking operations where mooring lines need quick attachment and release at fixed points
- Construction site crane setups using the block as a fixed redirection point for hoist lines
- Truck-mounted winch systems on recovery and towing trailers where space and weight are limited
- Industrial rigging in manufacturing plants where a fixed pulley is needed to redirect lifting cables
- Agricultural equipment towing and lifting where a durable, weather-resistant block is required
- Temporary rigging setups in infrastructure projects with frequent repositioning of lifting points
- Offshore platform deck systems where corrosion resistance and secure line control are critical

How It Compares With The Alternatives
An honest read on where this pattern wins and where another one would serve you better.
| Alternative | Honest Trade Off |
|---|---|
| Fixed cheek block without lid | The hinged lid allows faster cable entry and exit without removing the block, reducing rigging time in repetitive operations |
| Open cheek snatch block | The enclosed cheeks protect the sheave from debris and misalignment, improving safety and longevity in harsh environments |
| Double sheave block | The single sheave version is lighter and more compact, ideal for space-constrained applications where a 2:1 mechanical advantage is sufficient |
| Screw pin block | The hinged lid design eliminates the need for a pin that can loosen under vibration, reducing the risk of accidental disengagement |
Use Guide
How To Use And Inspect Mounting Block with Eye
- Verify the stamped working load limit matches the calculated line load, not the winch rating
- Ensure the hinged lid is fully closed and locked before applying load
- Feed the rope through the sheave from the open side, avoiding side loading
- Check that the sheave rotates freely by hand before use and shows no binding
- Inspect the lid hinge and locking mechanism regularly for wear or deformation
- Retire the block if the eye shows deformation, the sheave seizes, or the marking is unreadable

Answers
Mounting Block with Eye FAQ
What is the purpose of the hinged lid?
The hinged lid allows quick cable threading and unthreading without removing the block from the mounting point, saving time in repetitive rigging operations
Can this block be used with synthetic rope?
Yes. The sheave is sized to accommodate synthetic rope from 7.7mm to 35mm, and the smooth surface reduces abrasion
What is the design factor for this block?
A standard 4:1 design factor, meaning the minimum breaking load is four times the stated safe working load
What certificates are provided with the order?
A Material Test Certificate to EN 10204 3.1 is supplied on request. Every batch undergoes proof load testing and dimensional inspection
Can you custom stamp a different tonnage or add our brand?
Yes. Custom tonnage stamping, private label marking, and OEM packing are standard options
How are the blocks packed for export?
Standard carton on pallet packing. We can configure the carton count and pallet pattern to suit your warehouse or retail pack. Goods can be held in our Qingdao warehouse free for two months
