Questions that will help determine the right strapping tool

May 29, 2019

Plastic or Steel strap?
What size and type of strap is being used ?
What type of load are you strapping? (Boxes, steel pipe, wood sheets, palettes etc.) ?
What is the load weight & dimensions ?
What is the load characteristics? i.e.: Does the load have any sharp edges?
What is the number of loads being strapped per day?
How many straps are applied to the load?
What are the environmental conditions where the product is being strapped?
What temperature is the load exposed too?

Determining Break Strength

Verify if the appropriate strap is being used for your application.

(Load Weight x 1.5) / No. of straps to be applied = Tensile of the strap

Ex: Maximum pallet weight = 1100 lbs to be held by 3 straps
(1100 x 1.5) / 3 = 550 lbs strap capacity

The recommended strapping tools would be for approx. 600 lbs “Break Load Strength”.

Determining Tension Requirements

Ex. Polyester Strap (15.5mm x 0.76mm thick)
Break Strength specified in Kg

Constant = 0.4
Break strength listed for this strap = 600 kg

Tension Requirement : 600 kg x 0.4 = 240 kg

Ex. Steel strap (19mm x 0.6mm thick)
Break Strength specified N/mm2

Strap break strength = 850 N/mm2
Constant = 0.4
Newton's / 9.85 = Kg.

Average Break Load: 19 x 0.6 x 850 = 9,690 (average break load)
9,690 x 0.4 = 3876 Newton's
Tension Requirement: 3,876 x 9.85 = 394 kg
