Tie down or direct lashing?


Common methods for load securing with lashing straps are friction (tie down) lashing and direct lashing. See all images to see the difference between both ways of lashing. We also included the explanation of the strap label and referring to those numbers in text below. 

When do you use STF and LC?

Although most products can be used for both types of load securing, different properties of the equipment are used for the calculations. Where the STF value (14) is used to create extra downwards force resulting in extra friction when tying down loads, the LC value (7) is used for Direct Lashing. When tying down loads on flatbed- or curtainsider trailers, the LC value of a lashing is of lesser importance and the STF value shall be used. The higher the STF value per lashing, the higher the friction force, resulting in fewer straps necessary to secure the load.

When applying Direct Lashing, the Lashing Capacity (7) of the equipment is used for load securing.

LC 2000 daN or LC 2500 daN?

In some assemblies, for example with the LoadLok 811 Superior ratchet, certified STF values up to 440daN can be reached with LC 2000daN. In that case using a LC 2000 daN strap is more ecomomic, but also taking safety into account.

Important: Using the correct properties in your load securing plans will increase security, reduce loading time and save on material costs. Contact LoadLok for advice in load securing.
