FIELD: transport engineering; material handling facilities. SUBSTANCE: device has longitudinal beams and cross beams secured on longitudinal beams by locking mechanism. Locking mechanism is made in form of box enclosing longitudinal beam. Fixing rod is placed between locking mechanism and beam. Stops are installed on surfaces of box and beam facing each other. One stop is installed on beam on each of two outer surfaces opposite to each other. Axes of stops lie in one projection onto horizontal plane. Stops in box are installed with displacement. Box and beam engagement over surfaces facing each other is provided. EFFECT: enhanced reliability of fastening of heavy loads, reduced time taken for their fastening and number of required fasteners. 2 dwg
