Equipment choice

Answering following questions will help you to make right equipment choice

  • Is it plastic or steel strap?
  • What is the using strap dimension and type?
  • What kind of produce needs to be strapped (boxes, steel pipes, wooden plates, bricks etc.)?
  • What is the load weight and dimension?
  • What is the load peculiarities (for instance, sharp edges etc.)?
  • How many strapping cycles are made a day?
  • How many strapping cycles are made per one package?
  • What is the working area conditions (temperature, moisture etc.)?
  • What is the strapping load temperature?

Determination of necessary strap breaking strength

Проверьте может ли использоваться лента
(Load Weight x 1.5) / Applying strap quantity = Strep breaking strength
For example: Max pallet weight is 100 kg; 3 straps are applied
(1000 x 1.5) / 3 = 500 kg
Breaking strength of necessary strap should be more than 500 kg.

Determination of necessary strap tensioning

Strap tensioning should not be more than 40% of its breaking strength
For example: polyester strap 15.5 mm x 0.76 mm
Strap breaking force is measured in kg
Constant is 0.4
PET strap 15.5 mm x 0.76 mm breaking force is 600 kg
Necessary strap tensioning: 600 kg x 0.4 = 240 kg
For example: steel strap 19 mm x 0.6 mm
Strap breaking force is measured in N/mm2
Steel strap 19 mm x 0.6 mm breaking force is 850 N/mm2
Constant is 0.4
N / 9.85 = kg.
Strap breaking force: 19 x 0.6 x 850 = 9 690 N
9 690 x 0.4 = 3876 N
Necessary strap tensioning: 3 876 x 9.85 = 394 kg
