  • chrome handle


What sizes are available for webbing buckles?

  • 1" 25mm---BS 800kg or 1000kg

  • 1.5" 35mm---BS 2000kg or 3000kg

  • 2" 50mm---BS 2000kg or 3000kg or 4000kg or 5000kg

The instructions for ratcheting buckles?


How to use the cargo strap buckles? ( How to fasten and release Adjustable lashing buckles?)


Prepare the Strap:

  • Make sure you have a suitable strap with a ratchet buckle attached at one end. The other end of the strap should be free.

Thread the Strap:

  • Pass the free end of the strap through the opening in the ratchet buckle's frame from underneath.

Wrap the Strap:

  • Position the strap over or around the object you want to secure. Make sure the strap is flat and not twisted.

Insert the Strap:

  • Guide the free end of the strap through the ratcheting mechanism, ensuring it passes over the gear and under the pawl.

Tighten the Strap:

  • Begin ratcheting by pulling the free end of the strap upwards. This will tighten the strap around the object.

Ratchet the Buckle:

  • Continue pulling the strap until you achieve the desired tension. The ratcheting mechanism will engage with each pull, creating incremental tightening.

Lock the Tension:

  • To lock the tension in place, release the strap momentarily. The pawl will engage with the gear teeth, preventing the strap from loosening.

Optional: Fine Adjustment:

  • If you need to make slight tension adjustments, you can use the release lever to disengage the pawl temporarily. Then, pull the strap to tighten or loosen it as needed.

Release and Unfasten:

  • When you're ready to release the tension, engage the release lever to disengage the pawl from the gear. This will allow you to easily pull the strap out of the ratchet mechanism and remove it from the secured object.

How to Release a Jammed Ratchet Strap

图片
When we use the ratchet strap , maybe we will meet the ratchet strap jammed. So we need to know why it jammed and how to release the jammed ratchet strap. How Ratchet Straps Jam and Get Stuck There are three reasons for ratchet straps jam or get stuck Not disengaging the ratchet all the way: The gear stays locked in place until you unlock it. Winding too much strap on the spool: This requires a little muscle and finesse to unjam. Needs a little lube: Happens with ratchet straps that don't work smoothly from being outside. How to solve these problems? 1) Ratchet Strap Isn't Fully Disengaged and Won't Release When the ratchet is fully closed it's locked into place and both pawls are engaged. When it is partially open both pawls are mostly engaged. You need to get the ratchet fully open in order for it to release. You do this by disengaging the two pawls. First, you need to squeeze the little handle to disengage the manual pawls.

What is the STF-Standard Tension Force? The abbreviation STF “Standard Tension Force” stands for the pre-tensioning force also called “Normal Tensioning Force”, which describes the force of the lashing strap. Put simply, with an STF value of 350 daN: you pull or push on a ratchet lever with exactly 50 daN (SHF) and can lift/move a weight of 350 kg with this force. The main reason for high pre-tensioning forces are the high-quality products, in this case, the ratchet and the lashing strap, which have been optimized for your application. The STF value to be achieved is defined by the European standardization: STF = min. 0.1 x LC and max. 0.5 x LC All products in our assortment of cargo safety are tested according to DIN EN 12195-2. STF – Standard Tension Force according to DIN EN 12195-2, always applies to a lashing belt system (ratchet, webbing and end fittings). The webbing, its length, composition, elongation, sewing and material thickness have a very large influence on the STF value
