FIELD: transportation.;SUBSTANCE: in lifting/lowering transportation device of product transportation container, means 2A, 2B gripping container have structure, in which several support pins 15 for container are arranged so that they can freely protrude and retract, and spring 20 for displacement of container gripping means 2A, 2B upwards is located between container gripping means 2A, 2B and columnar support element 6a, 6b to support container gripping means 2A, 2B so that said container gripping means 2A, 2B can freely be lifted and lowered. As a result of upward biasing force of spring 20, container gripping means 2A, 2B are supported at balance height H3 in equilibrium with their weight and are capable of vertical movement from equilibrium height H3 serving as the centre of said displacement. When container gripping means 2A, 2B lift container 1, means 2A, 2B gripping container receive container 1 weight, lower from equilibrium height H3 and are supported at fixed height of columnar support element 6a.;EFFECT: higher reliability of transportation.;4 cl, 14 dwg
