Each trailer provides different prerequisites to attain positive locking even if the type of load does not normally permit this, such as pallets with sacks, or the packaging is too weak. Included in this auxiliary equipment are perforated rails in the bed of the vehicle, the Joloda rails installed recessed into the bed, inserts, transverse beams etc. The Schmitz Cargobull SPEED CURTAIN, a tarpaulin with integrated stanchions, is included in this. Another option is to block the load using the special structure of the trailer, or using straps.
Direct lashing – inclined, diagonal, with loops
With direct lashing, in contrast to lashing down, the load is directly retained in position by the lashing equipment. It is a positive form of locking that is similar in its function to limiting the loading area. For inclined lashing, a minimum of eight means of lashing, two each at each corner of the load, is directly tensioned to the loading surface at an angle of 90o. For diagonal lashing, a minimum of four means of lashing is required,diagonally tensioned from the corners of the load (not at a right angle) to the loading surface. Thereby, the four corners of the load are secured. A combination of these two direct forms of lashing is particularly suitable for securing heavier loads. The head loops secure the load at the front. Therefore, the side and rear inertial forces occurring are counteracted using further head slings or by lashing down.
