Symlock, the adapter with added value

Simple conversion of the backhoe bucket into a shovel bucket

Symlock adapter

Using the Symlock adapter, you can turn a backhoe bucket into a shovel bucket in a flash and vice versa – by rotating the bucket by 180°. The characteristic lock plate and the coupling shaft on the adapter are replaced by two symmetrically arranged coupling shafts with flat surfaces for the lock plate and locking bolts of the quickcoupler. This enable both the conventional position in the adapter as well as a fit rotated by 180°.

Backhoe bucket with Symlock adapter in normal backhoe use is simply rotated by 180° for shovel bucket use.

Shovel bucket use:

  • all advantages of the Lehmatic quickcoupler system are retained
  • ideal for limited range
  • for material loading or for filling in front of walls
  • when digging ditches
  • for obstacles

5-year warranty on clearance-free fit of the quickcoupler in the Symlock adapter. Only applies for the use of original Lehnhoff quickcoupler components.
