Cam Buckle With Lashing
A cam buckle lashing system is a specialized, lightweight, and efficient cargo-securing device. Unlike a ratchet strap that uses a mechanical winch to tension the webbing, a cam buckle relies on a spring-loaded metal tooth (the "cam") that grips the webbing strap, allowing for quick, one-handed tensioning and release.
Here is a breakdown of the technical and practical details :-
What is a Cam Buckle Lashing System?
It is a "pull-to-tighten" system. The webbing is threaded through a metal frame containing a serrated lever. When the strap is pulled, the lever allows the webbing to pass through in one direction. When released, the serrated cam bites into the webbing, locking it in place. It is designed for applications where tensioning speed is more important than achieving extremely high tension.
Primary Applications
Because they provide controlled tension without the extreme force of a ratchet, they are ideal for:
- Logistics & Transport: Securing light-to-medium weight cargo, cartons, and boxes inside delivery vans or trucks to prevent shifting during transit.
- Automotive & Leisure: Ideal for securing motorcycles, dirt bikes, or roof rack luggage (skis, surfboards, kayaks).
- Retail & Display: Used for bundling products, securing roll cages, and pallet stabilization.
- General Industry: Bundling pipes, conduits, or scaffolding components for short-distance transport within a facility.
Working Load Limit (WLL) and Safety
When marketing these products, it is vital to distinguish between WLL and Breaking Strength (BS).
- Definition: The WLL is the maximum force that the lashing system is designed to sustain during normal use. The Breaking Strength is the point at which the hardware or webbing fails entirely.
- Safety Ratio: In the industry, the WLL is typically calculated at 1/3 or 1/2 of the Breaking Strength (depending on international standards like EN 12195-2).
Typical Ranges:
- 25mm Webbing: Most commonly has a WLL range of 250 kg to 500 kg.
- 50mm Webbing: Used for heavier applications, with a WLL range often between 1,000 kg and 2,000 kg.
Important Professional Note: Always advise your clients that the WLL is the limit they must respect. For your product sheets, clearly state: "Do not exceed the Working Load Limit (WLL). These straps are not intended for heavy-duty lifting; they are for load restraint only."
Advantages of Cam Buckle Lashing
The primary advantages make these a preferred choice for specific "fast-turnaround" cargo:
- Speed: Much faster than ratchet straps because there is no winding mechanism involved. You simply pull and lock.
- Anti-Damage: Because you cannot apply the extreme, bone-crushing tension possible with a ratchet, these straps are less likely to crush or damage fragile cargo or soft finishes on motorcycles and furniture.
- Ease of Use: User-friendly operation. Anyone can learn to use them in seconds, making them excellent for retail end-users and delivery personnel.
- Low Profile: The compact size of the cam buckle makes it easier to store and use in tight spaces where a bulky ratchet handle would be difficult to maneuver.
- Cost-Effective: Generally cheaper to manufacture and purchase than high-tension ratchet systems.
