This section explains how common securement devices—such as portable winch straps, ratchet straps, and corner protection—help create static securement for open deck loads. It also outlines the types of strap damage you should look for and reinforces that any damaged strap is unsafe for use.
Securement Devices and Damage Inspection
Learning Objectives
By the end of this section, you will be able to:
– Explain the purpose and function of common securement devices used for open deck loads.
– Describe how portable winch straps, ratchet straps, and corner protection help create static securement.
– Recognize common forms of damage found on tie‑down straps.
– Determine when a strap is unsafe for use.
Lesson Content
1. Portable Winch Straps and Ratchet Straps
Portable winch straps and ratchet straps are among the most frequently used securement devices for open deck loads. They allow you to apply consistent downward pressure on the cargo, reducing movement and helping create a static load. Winch straps are tensioned using a winch system mounted to the trailer, while ratchet straps rely on a built‑in ratcheting mechanism.
To achieve full Working Load Limit performance, you must apply and maintain proper tension. Make sure the strap lies flat, is free of twists, and is not obstructed. If tension is too loose, the cargo can shift. If tension is too tight, the strap may become overstressed or damaged.
2. Corner Protectors and V‑Boards
Corner protectors and V‑boards preserve the integrity of both the load and your securement equipment. They distribute pressure across a wider area, preventing straps from cutting into sharp edges and reducing the risk of abrasion. These devices also help protect the load from deformation or edge damage.
Place corner protectors or V‑boards anywhere the strap contacts a sharp edge, rough surface, or potential friction point. This helps extend strap life and supports more stable, even tension across the strap.
3. Identifying Damage on Tie‑Down Straps
You must inspect tie‑down straps before each use. Any significant wear reduces their strength and makes them unsafe. Common forms of damage include cuts, fraying, burns, abrasions, weakened stitching, or thinning of the webbing. Even small cuts or tears can compromise performance under stress.
Inspect any hardware attached to the strap as well. Bent hooks, cracked ratchet mechanisms, or corroded fittings all indicate that the device may fail. If you find any damage, remove the strap from service immediately to avoid cargo loss and ensure roadway safety.
Scenario / Case Study
You are securing a load of lumber using several portable winch straps. During your inspection, you notice light fraying along the edge of one strap and a small cut—about an inch long—on another. One of your corner protectors is also cracked. Because you are short on time, you consider using the damaged equipment.
Reflect on the following questions:
– What risks arise if you choose to use straps with visible fraying or cuts?
– How might a cracked corner protector affect strap performance during transport?
– What steps should you take before securing your load to ensure safety?
