LoadElastomer

  • - Self-centering capability 
  • - Dynamic load damping properties 
  • - Minimal reaction to side forces 
  • - Simple, rugged, and flat design 
  • - High resistance to environmental influences and chemicals 
  • - Easy installation 
  • - Maintenance-free

 

Application

The elastomer mounts are designed for load input to the Schenck ring-torsion load cells optimized with regard to measurement. They are used with all kinds of industrial weighing systems, e.g. hopper scales, roller conveyor scales, crane scales, road weighbridges.

 

Construction

The elastomer mounts consist of the load reception plate for load input, the elastomer for selfcentering, and a base plate for load output to the supporting structure. Lateral movement must be limited depending on the installation
situation. Lifting off has to be prevented by using appropriate hold-downs.

 

Functions

The weight to be measured is applied to the load cell via a load reception plate. Due to the special design, the vertical deflection is extremely low and proportional to the load. Occurring side forces deform the elastomer in a parallel direction. The mount centers automatically when relieved of side force. Depending on the admissible area pressure of the load receptor, it may be necessary to install a load distribution plate over the contact plate. The necessity for this
measure must be checked each time when the load receptur is a concrete construction.

 

Important:
Lifting and lowering of the load application elements may cause a non-repeatable load to be applied to the load cell and entail measuring errors in the entire weighing system. Therefore, ensure that the load cell in the elastomer mount is never totally relieved. Select minimum preload such that load cell and contact plate, or base plate, are always positively tied.

 

Elastomer Mounts DEM 0.25 t – 0.50 t for RTB Load Cells 

– Elastomer is installed above the load cell

– Elastomer is bolted or welded to the connecting structure with two straps fitted on sides

– Height adjustment (max. 5 mm) via shims

– Alignment through shifting the base plate secured by bolted or welded fixing pieces

 

LoadElastomer1

 

Elastomer Mount VEN 1 t – 4.7 t for RTN Load Cells

– Elastomer is installed above the load cell.

– Elastomer is bolted or welded to the connecting structure with two straps fitted on sides

– Height adjustment (max. 5 mm) via shims

– Alignment through shifting the base plate secured by bolted or welded fixing pieces

– Alternatively, the fixing can be realized by using a centering pin

– The head and base plates of the elastomer mount can be screwed onto the connecting structure directly. Thanks to the optional weld-on plates, there is no need for drilling and thread cutting on the connecting structure. The weld-on plates are welded onto the structure after alignment of the load carrier, and their tap holes then accommodate the mount. The weld-on plates for the 1 – 4.7 t capacity range can be arranged above and/or below the VEN mount. 15 mm additional headroom is required for each plate.

LoadElastomer2

 

Elastomer Mount VEN 10 t – 470 t for RTN Load Cells 

– Elastomer is installed below the load cell

– Contact plate is secured by a centering piece bolted or welded onto the supporting structure

– Height adjustment (max. 5 mm) via shims

– Alignment through shifting the elastomer secured by bolted or welded straps

– The head and base plates of the elastomer mount can be screwed onto the connecting structure direct. Thanks to the optional weld-on plates, there is no need for drilling and thread cutting in the connecting structure. The upper weld-on plate is welded onto the structure after alignment of the load carrier, and its tap holes then accommodate the mount. On the mount underside, the elastomer is welded on directly. Additional headroom required for the weld-on plate:
VEN 10 – 22 t: 20 mm
VEN 33 t: 25 mm
Other rated capacities available on request.
