The objective of the invention is to realize like this: a kind of suspender LOAD CELLS of container gantry crane; Comprise pressing plate, elastic body, backing plate and be provided with the resistance strain gauge of sensor connector; Resistance strain gauge is fixedly installed on the elastic body; Pressing plate and backing plate are set in elastomeric upper/lower terminal face, are characterized in being provided with roll shaft between elastic body and the pressing plate, and said elastic body is the discoid load member that is provided with groove, boss, axle sleeve and induction planes; Said elastomeric upper surface is provided with trapezoid platform and groove; Said elastomeric lower surface is provided with boss, and said boss is provided with spherical support; Said induction planes is the gap that is arranged on the elastic body outside; Said roll shaft is the end face bearing that the taper ball is set on the bearing frame; Said pressing plate is the ring-type plectane that is provided with upper shaft hole and flange, and said flange one side is provided with the inclined-plane; Said backing plate is the ring-type plectane that is provided with lower shaft hole and round pool; Roll shaft is arranged in the elastomeric groove; Pressing plate is arranged on the roll shaft and elastomeric upper surface suit; Backing plate is arranged on the axle sleeve and elastomeric lower surface suit; Elastic body is to contact with backing plate with spherical support in round pool, and resistance strain gauge is fixedly installed on the induction planes in the elastic body outside strain signal through sensor connector output.
Said trapezoid platform, groove, boss and axle sleeve and elastic body are the concentric circles setting.
Said spherical support and round pool are that several and correspondence are provided with.
The present invention compared with prior art has aligning carrying, good reproducibility, accurate measurement is accurate, easy to maintenance and precision is high characteristics; Solved the problem of repeatability, precision and accuracy effectively; And it is simple in structure; Low cost of manufacture, easy to install and use, especially be fit to the use of weighing of the container gantry crane of port and pier.
