3.1 VRG-grab models
The VRG demolition and sorting grab is a grab especially designed for demolition and
sorting operations. The VRG grab has a low construction height and a wide spread of
the shells. Also refer to the dimensions in the table with technical data.
The shells have been provided with wear resistant lower knives. Each shell is driven by
a hydraulic cylinder.
The grab has been provided with a swivel head for unlimited rotation of the grab, both
clockwise and counterclockwise. The hydraulic components and hoses are fully
protected.
For mounting the VRG grab to the excavator the VRG grab has been fitted with
excavator dependent suspension plates or adapter plates for the Connect'o'maat quick
exchange system®. Figure 3.1 shows the version with the adapter plates for the quick
exchange system®
The following options are available for the VRG demolition and sorting grab:
- exchangeable lower knives
- demountable side plates: (does not apply to the VRG 05 and 10)
loading plates for sorting operations
breaking plates for sorting demolition materials
- 6/2 valve: when the excavator has only a separate hydraulic function this valve can
be used to control two hydraulic functions of the piece of equipment (does not apply
to the VRG 05 and 10).
