inspect any straps involved in a load shift incident - do not use them if they’re worn or damaged, even if the damage appears to be minor Step 3:With a drill and proper bit, create a hole on each end of the second piece of lumber for your screws to attach to the first piece at an angle (about 20 degrees). Frictional lashing is most effective when the angle of the lashing relative to the load bed is as close to vertical as possible. If the angle is less than 30°, the lashing will not be effective.

testing has been carried out to establish the specific coefficient of friction for that load and vehicle combination If this is not possible (for example, if it would overload an axle), you must use an additional method of securing. You could: They’re an effective load securing method when used correctly, but they can be damaged easily. Keeping straps in good conditionMost ratchet straps used in the UK have a label attached to them with information about their strength and how they can be used. You can keep your straps in good condition by using sleeves or protectors over corners and sharp or abrasive edges. Make sure you use enough lashings to prevent load movement under normal driving conditions. If there is a serious load shift, enforcement agencies will refer to BS EN 12195 1: 2010 Load restraining on road vehicles Safety Part 1: Calculation of securing forces when deciding if you have used enough lashings.

The friction between most loads and the standard load beds of most vehicles and trailers is generally low. The weight of a load alone cannot be relied on to keep it in place once the vehicle is moving, even if the load is very heavy and cannot be moved by hand when the vehicle is stationary. Design the larger piece so that about 3″ of the flukes and all of the shank are contained in a resting posi-tion. Design the crown rest with at least an inch of width outside either edge of the crown. Straps used in the UK usually have an STF of 350daN or lower. For some loads, you may need to use straps with an STF of 500daN or more to reduce the number of lashings required. Other information on the strap

Yes. I used to work in a boatyard and you will be amazed at how much hull deflection you can get on some boats, and more so with the modern stuff as much of it seems to be much lighter in construction than the older boats. a high-friction surface with a certified coefficient of friction is used between the load and load bed Step 1: Cut the pieces of lumber to the desired length – generally around 4-6 inches long. Both pieces should be cut to the same size. Draw a centerline on the piece of wood and transfer the whole shape by stationing your cutout or template on the centerline. Then draw around the template, and flip the template over to get the other, exactly match-ing side. The STF is the working tension in the strap created when the lashing is ratcheted down over the load. It’s only used to calculate the number of lashings needed in frictional lashing.

The same holds true if you need to apply de-icers or other treatments such as washer fluid or anti-freeze when temperatures drop below freezing. increase the height of the load (for example, by placing empty pallets or other suitable item on top of it) The LC is the maximum force the lashing can safely withstand without damage when pulled in a straight line. It’s only used to calculate the number of lashings needed in direct lashing. Standard tension force (STF)They make a great addition to your toolbox for added safety measures when working on your vehicle, but they should also be used with other precautions in place. look for any signs of damage on the straps before using them - you must replace any straps that are significantly damaged This is one of the few times when US ing a hammer on a chisel is ap-propriate. Hold the chisel along the forward vertical edge of the recess you are making, then tap it with a leather or wood mallet (not a metal hammer). Because you are cutting across the grain, the chisel will not penetrate very deeply. Loop (choke) lashing is particularly effective when these loads are carried at an angle over the headboard of a vehicle or trailer. You must use a minimum of 2 loop (choke) lashings for this type of load unless each item is individually clamped to the headboard.
