<p>The tightening and opening of rope loop for sucuring logs in the vehicle is simplified by the use of telescopic cylinders (3) at the end of beam (1). The first stage of the hydraulic cylinders is double acting while the second stage is single acting. The tightening mechanism includes pullyes (11, 12) held by the housing of cylinder and the rod of the first stage of the cylinders. The opening mechanism of the loop (4) of rope comprises pulleys (18, 19) attached to the housing and rod of cylinder second stage to control staying rope (20). The bunch of logs is made up after opening loop (4) by pressurizing the rod end chamber of cylinders (3) first stage and simultaneously feeding the second stage. After the placement of the load, the loop is shifted by a separate cylinder.</p> |
