Abstract
A load cell is provided with protection against damage from overload. The load cell has a load receiving member, a main member and a load transmitting member. The main member has a movable portion, a fixed portion and a first parallel guiding member for connecting the fixed portion and the movable portion. The load transmitting member has a first mounting portion for mounting the load receiving member, a second mounting portion for mounting the movable portion and a parallel guiding member for connecting the first mounting portion to the second mounting portion. The first mounting portion is movable vertically relative to the second mounting portion when a load being applied on the first mounting portion. The load-transmitting member is a single piece. The load cell also has a stop portion for preventing the first mounting portion from further moving downwardly for overload protection.
