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.

A tensioning assembly for a strapping tool having a main frame and a feed wheel for drawing tension in a strap loop disposed about a package which comprises: a tensioning assembly support mounted on said frame; a first lever pivotally connected to said support; transmission means engageable by said first lever for rotating said feed wheel to tension the strap loop; a second lever pivotally mounted on said first lever; the second lever having a handle on one end and an engaging arm on the other end; stop means on said support adapted to be contacted by said engaging arm for stopping rotation of said second lever; and means for biasing said second lever with respect to said first lever about said pivotal mount to hold said engaging arm out of engagement with said stop means permitting movement of said second lever to move said first lever for rotating said feed wheel, whereby the feed wheel can be rotated to achieve a certain predetermined tension after which the second lever overcomes said biasing force and the engaging arm contacts said stop means to stop the tensioning action.
