Pneumatic strapping of textile or lashing strap is particularly worthwhile if constant high tension forces of up to 7,500N are to be achieved. This can be the case, for example, due to safety regulations. The prerequisite for the use of a pneumatic strapping tool is a compressed air connection, which then also defines the stationary strapping location. These extremely robust devices are suitable for continuous use and can be used for strap widths up to 50mm.
