Why Ratchet Straps & Harnesses Are Used in Cargo Securing
Cargo that is not properly restrained is exposed to unnecessary risk during transport. Vibration, sudden braking, impact, and movement can allow poorly secured loads to shift, causing product damage, container damage, and safety hazards.
Ratchet straps and harnesses are designed to reduce this risk by offering:
- Fast, adjustable tensioning for quick and secure load restraint
- Reusable, practical application for repeat shipments and mixed cargo
- Consistent tension retention during movement and vibration
- Lightweight handling and ease of application
- Reduced cargo movement, damage, and insurance claims
These properties make ratchet straps, harnesses, and slings well suited to modern logistics environments where cargo may move between road, rail, and sea transport.
Important Product Scope Clarification
Ratchet straps, harnesses, and slings are supplied as general cargo securing accessories for adjustable, everyday load restraint.
Where cargo requires engineered, high-strength restraint backed by certified breaking-strength data, DunLash also supplies SGS-tested woven polyester lashing and composite polyester strapping systems — see those pages for full daN specifications. Our specialists can advise which securing method suits your cargo, weight, and transport route.
