ABSTRACT:
A strap tensioning tool having a feed wheel driven through a tensioning assembly by a load-sensing handle. The feed wheel and tensioning assembly are mounted in a frame for pivotally swinging from a first position in which tension can be drawn on a strap loop by the feed wheel to a second position in which tension cannot be drawn by the feed wheel and whereby the strap can be inserted into, or removed from the tool. The load-sensing handle has a drive lever which is rotated to drive the feed wheel by a handle lever pivotally mounted on the drive lever, whereby the feed wheel can be rotated to achieve a certain predetermined strap tension, after which the handle lever overcomes the force of a biasing means between the handle lever and drive lever and moves relative to the drive lever about the pivotal mount until the handle lever contacts fixed stop means preventing further rotation of the handle lever to thus stop the tensioning action.
