The previously known arrangements for pendulum limitation are designed so that the pendulum movement or the f horizontal movement of the force application plate | is limited in every direction, i.e. every bearing has a pendulum rim on all sides. For this purpose, e.g. on the force application plate of each bearing three at about 120 ° to each other

The object of the present invention is to provide a weighing device to create with pendulum limitation and Abhebesicharung, which is structurally simpler than the previously known bearings and at dBm the setting of the pendulum play in the built-in Condition can be made easily. This object is achieved by the features specified in the patent claims. The claims also relate to expedient embodiments of the invention.

With the solution according to the invention, the construction of the pendulum limiter on a load cell bearing is much simpler than before. Only a single adjustment device for the pendulum limit and / or a lift-off safety device is required on each bearing. Oa as a rule at least three load cell bearings are used for weighing arrangements, it is sufficient if an ainarr. A limitation of the pendulum play is made in one direction of movement.

V / 8it8rhin the cantilever piece 10 at the lower end has lateral shoulders 12, 12 * which can be welded on. In the shoulder 12 * a screw 13 is arranged in a single through hole with a suitable clearance. The screw 13 goes through a through hole in the base plate 3 and is screwed into the intermediate plate 1. With the help of lock nuts 14, a lift-off protection is formed which prevents the force control plate 7 from lifting off from the printing block 8 or the weighing cell 5. When the lock nuts 14 are tightened against the shoulder 12 ′, the force introduction plate 7 is locked in relation to the load cell 5.

The load cell bearing can also be designed without an intermediate plate 1. In this case, the base plate 3 becomes more suitable Way connected to the supporting structure. The lift-off protection with the screw 13 is then screwed into the base plate 3.

To secure transport, it is advisable to use the d8m Kragstück 1o opposite side of the base plate between Force introduction plate 7 and base plate 3, a removable connecting piece 15 is inserted and screwed to both plates (Fig. 1). This results in a closed, stable unit for transporting the warehouse. The fuses can too can be used as assembly aids during assembly.
