The chain tensioners are designed with an ergonomic lever, easy to operate with one hand. They are made of forged or cast steel.
The tensioner is provided with hammerlock hooks attached to the chain.
The chain kits have the following markings:
EN 12195-1
Load securing devices for road vehicles. Calculation of lashing forces
This European Standard is applied in the design of securing methods (blocking, lashing, and combinations) for securing loads in transport on road vehicles or parts thereof (trucks, trailers, containers and swap bodies), including their transport by ship or train and/or combinations thereof. For the dimensioning of load securing a distinction is made between stable loads and loads prone to tilting. In addition, acceleration factors for surface transport are specified.
For overhead lashing, the force loss of the lashing tension at the outer edges between the load and the lashing is taken into account.
The lashing forces taken into account for the calculation of this standard are static forces produced by the blocking or tensioning of the lashings and by dynamic forces, which act on the lashing as a reaction to the load movements.
EN 12195-3
Load securing devices for road vehicles. Safety. Securing chains.
This part of EN 12195 specifies the general safety requirements to be met by lashing chains and their combinations with chains for the safe transport of goods in vehicles, such as trucks and trailers used on road or on board ships or in railroad wagons, and/or their combinations. The standard includes only hand-operated tensioning devices with a maximum force of 500 N.
Royal Decree 563/2017
Pursuant to the Royal Decree regulating the conditions under which technical roadside inspections of commercial vehicles circulating in national territory must be carried out, regardless of their state of registration, in order to improve road safety and the environment.
Load securing chain kits should be inspected prior to use to ensure that :
Be very careful with the tensioner movement lever.
Do not heat treat them as it may affect the lashing capacity.
Never repair or reshape a chain tensioner, chain or hooks by welding, heating, or bending as this may affect the capacity.
Loosening the lashing: It must be ensured that the stability of the load is independent of the lashing chain, and that slackening the chain must not cause the load to fall out of the vehicle, as this would endanger the personnel involved.
Before unloading, the lashing chains must be removed so as not to obstruct the load.
During the period of use, regular checks should be made to detect defects or damage.
Regular inspections must be carried out according to the safety standards of each country. This is necessary because the products may be affected by wear, misuse or overloading, etc... producing deformations or alterations in the structure of the material.
Inspection should be carried out at least every six months or even more frequently if the conditions of use and work are extreme.
For a long service life and to reduce wear, it is recommended to lubricate regularly the moving parts of the chain kit.
USAGE
Before each use of the chain kit, it should be inspected for defects or damage. An unidentified or defective kit should never be used.
1. Inspect the chain kit and make sure it is free of any defects or damage.
2. Attach one of the hooks of the chain kit to the element to be attached in such a way that it cannot come loose.
3. Attach the 2nd hook to the truck bed.
4. If you have excess chain, before attaching the 2nd hook, use the chain shortening device to manually adjust the excess chain.
5. Adjust the ratchet with the lever to its maximum tension.
6. To ensure proper clamping, check the tension of the chain kit after about 5 to 10 minutes of travel.
