  • Publication number: 20090188398
    Abstract: A strapping tool for tensioning a strap around a load, adhering the strap onto itself, and cutting a feed end of the strap, includes a body having a foot on which the strap is disposed during a strapping cycle. The body housing and/or forming a part of a tensioning element and including a welding element. One or more pneumatic motors tension the strap and drive the welding element. A pneumatic module is mounted to the body. The module has a compressed gas inlet to the module and is configured for controlling the flow of compressed gas to the one or more motors. A handle is mounted to the body and operably connected to the pneumatic module. The handle is configured for manipulating the tool and includes an actuator for permitting and isolating the flow of compressed gas to the pneumatic module. The handle is orientable so as to allow a user to select a desired handle orientation for operation of the strapping tool.
