发明名称 LOAD CELL ASSEMBLY AND TONG ASSEMBLY INCLUDING SAID LOAD CELL ASSEMBLY
摘要 A load cell assembly (20; 220; 80) comprises load cell mounting apparatus (21; 31; 221, 231) which translates tensile and compressive forces on said load cell assembly into a unidirectional force which can be measured by, for example a tensile-load indicating load cell (40), a compression-indicating load cell (240) or a shear-indicating load cell (81).
