HANSEL E Type Rock Cutter Heads

The Hansel Dredge Cutterhead offers the very latest in HANSEL design and manufacturing technology.

Each cutter head is a custom-engineered system. Hansel dredging specialists carefully analyze customer requirements and operating conditions to arrive at the design criteria for digging angle, arm spacing profile and size, and tooth location and orientation.

Hansel engineers match the design criteria with field proven innovations to produce a cutterhead that provides maximum dredge productivity.

Hansel adapters are a unique dredge cutter head system. The system features a method of attachment that is much stronger than traditional weld-on adapter systems while reducing maintenance requirements.

The adapter installation uses a ball and socket joint. The cutter head arm has cast “sockets” to receive the “ball” of the adapter, which is secured to the socket with an angle weld.

A high-impact epoxy lining in the socket ensures a precise fit and permits the tooth angle to alter as operating conditions change. Adapter change-outs are much faster than with traditional weld-on adapter systems, and the point tip orientation is easily maintained.

The Hansel adapter system transfers impact loads throughout the arm, allowing the cutter head to withstand extreme punishment.

Every Hansel Dredge Cutterhead is unique: each comprises proven features matched to customer requirements. Examples of this customized design approach include:

• Hub-mounted teeth assist a suction cutter dredge with a hydraulically advanced spud to step forward
• Ring mounted teeth provide an extra measure of wear protection
• Arm spacing, profile and tooth type are determined to suit the material being dredged

The superiority of the Hansel Dredge Cutterhead is the result of unmatched design and metallurgical capabilities.

Computer-aided design (CAD) allows Hansel engineers to design cutter heads and their components with speed and accuracy.

• Optimum arm spacing and size can be quickly determined
• Accurate tooth location and orientation are the primary consideration in cutter head performance
