Cutter Ladders
VOSTA LMG cutter ladders are available in two standard types: pipe- or box- type.
The cutter ladders are fitted with side wire blocks, an hoisting block and locking pins(or other means) to change the ladder hoisting wire in a safe way. The larger cutter ladders are fitted with tilting pins to change the rubber suction/pressure hose between the ladder and the dredgers' hull.
To certain limits, the cutter ladders can be lengthened/shortened to the needs of the customer.
All cutter ladders are equipped with VOSTA cutter heads including the electric or hydraulic drive system.
All cutter ladders are fitted with an flow-optimized suction mouth inlet pipe.
Pipe Type
The pipe-type cutter ladders are designed to meet the demands of standard cutter suction dredgers.
The ladder is provided with:
- Suction line
- Side wire swivel sheaves
- Ladder front piece
Box Type
For more demanding soil types, increased cutter power is necessary and this also requires heavier constructed cutter ladders to support and resist these forces. This requires a box-type cutter ladder to create a stiff and rigid design.
The ladder is provided with:
- Suction line
- Side wire swivel sheaves
- Ladder front piece
- Optional underwater pump
