HS03V (Variolock VL 30)

The fully hydraulic quickcoupler for mini excavators

Each attachment safely in use, in just seconds

The fully hydraulic HS-V (Variolock) energy circuit coupling system makes changing all
attachments easy, safe and quick. The driver can comfortably change all tools including
the hydraulic connection at the press of a button from the cab, without having to leave
the cab and without having to depend on other personnel.


Very economical thanks to time and cost savings

  • More effective working: tool change makes sense also with short work cycles
  • More safety and convenience for the driver
  • Cost reduction due to preservation of machine and attachments
  • Prevention of hose ruptures
  • Less contamination of the hydraulic system, environmentally friendly

    • Sealing protects the valves from dirt while using non-hydraulic attachments

    • 2 load hook as standard

    • Quickcoupler with integrated valve block (S- block)

    • Valve block in the adapter of the attachment (A-block)


Locking process

When locking the quickcoupler with the adapter, the valves are opened automatically. The extremely short stroke of 0 - 3.5 mm allows a full flow of oil immediately. The quickcoupler is always safe and locked without backlash through permanent pressurisation.

S-block: valve block in quickcoupler

  • Flexibly and centrally stored on the underside in the quickcoupler
  • With five short stroke valves
  • Including leakage oil lines
  • Integrated hydraulic tension support ensures a solid hydraulic connection between
    S-block and A-block

 

A-block: valve block in the attachment

  • Mounted in the attachment adapter
  • Short stroke valves are flush with the block surface and thus easy to maintain
  • Valves optimally adapted to the respective tool:
    Two valves: e.g. tilt bucket, hammer
    Three valves: e.g. drum cutter, rigid compactor
    Four valves: e.g. rotatable grapple
    Five valves: e.g. rotatable compactor

 

Tilt bucket:

2 valves

 

Sorting grab:

4 valves

 

Hammer:

2 valves

 

Rotatable attachment compactor:

5 valves
