FIELD: measurement equipment.
SUBSTANCE: invention relates to weight-measurement equipment and may be used on railway transport to weigh large-capacity containers in process of handling. Crane scales for weighing of large-capacity containers comprise hooks mounted on cross beams in cases with upper and lower support rings. Electric motor and traction rods, on one of which a driving nut is rigidly fixed, are mounted on cross beam. Figure lever is installed on top of each hook. Each hook is installed by means of two bearings with the possibility of rotation around vertical axis, fastening nut and upper bearing are installed on hook tail. There is an elastic element of sensor in cavity of case between upper and lower supports rings. Sensors are connected to unit of signals processing.
EFFECT: improved accuracy of weighing due to installation of each hook of rotary lock into strictly vertical position.
