Attachments
Ripper hook
[Translate to English:] Grafik vom Ausbrechzahn in rot mit weißer Outline
Ripper hook

Ripper hooks are suitable for all areas where a targeted use of force concentrated on one tooth is required.

Use in the metallurgy
The ripper hook is used for breaking out and cleaning ladles, electric furnaces and converters directly in the extreme hot temperatures up to 1,400°C.

Mining applications
The ripper hook is used for scaling and tearing rock and stone. The tool has a replaceable wear tip made of special material.

Advantages:

  • Use in hot working areas
  • Exchangeable tooth tip
  • Quick fitment to the telescopic boom

Double ripper hook
[Translate to English:] Grafik Doppelausbrechzahn in rot mit weißer Outline
Double ripper hook

Ripper hooks are suitable for all areas where a targeted use of force concentrated on one tooth is required. The double ripper hook is a further development of the ripper hook and has an additional, hard faced ripper tooth. 

Use in the metallurgy
The additional, armoured ripper tooth is used for easier removal of slag skulls, allowing the pulling force of the boom to work while the exchangeable tip works with the pushing force, in one operation. 

Mining application
The double ripper hook is used for scaling and tearing rock and stone.

Advantages:

  • Use in hot working areas
  • Exchangeable tooth tip
  • Quick fitment to the telescopic boom
  • Saving of operation steps during the cleaning process

Porous plug pushing tool
[Translate to English:] Grafik Stoßdorn in rot mit weißer Outline
Porous plug pushing tool

Application metallurgy
The porous plug pusher is an attachment tool and is fastened directly to the ripper hook. It is used to push out the purging plug in ladles when hot. The pusher has a replaceable point made of special material suitable for the hot area.

Advantages:

  • Use in hot areas
  • Exchangeable point
  • Quick fitment to the ripper hook by means of 2 pins

Tap hole drill
[Translate to English:] Grafik eines Abstichlochbohrer in rot mit weißer Outline
Tap hole drill

Application Metallurgy
The tap hole drill is attached directly to the ripper hook by means of 2 pins and is used to drill out the worn tap hole sleeve on converters, precisely and in a short time. The replaceable drill heads are equipped with hard-faced wear blades and can be easily and quickly attached to the drill rod.

Advantages:

  • Exchangeable drill heads
  • Quick fitment to the ripper hook, simply by means of 2 pins
  • The drill tube length and drill tip diameter can be chosen to fit the requirements of the converter

Ripper bucket
[Translate to English:] Grafik eines Reißhakenlöffel in rot mit weißer Outline
Ripper bucket

Use in the metallurgy
The ripper bucket is used for cleaning blast furnace channels, excavating materials in electric arc furnaces and cleaning the pits under the BOF vessels.

Advantages:

  • Quick fitment to the telescopic boom
  • Exchangeable tooth tips
  • Additional ripper tooth to loosen solid material

Single-point lifting bail
[Translate to English:] Grafik einer Kranaufhängung in rot mit weißer Outline
Single-point lifting bail

Application Metallurgy
The single-point lifting bail is used for internal transport of the machine. It is attached directly to the cradle of the telescopic boom.

Advantages:

  • The crane operator can easily and quickly position the crane into the attachment to lift the complete machine
  • No need to attach a chain harness to the machine
  • Work safety is increased as no one has to climb on the machine

Hydraulic hammer
[Translate to English:] Grafik Hydraulikhammer in rot mit weißer Outline
Hydraulic hammer

Application Metallurgy
Hydraulic hammers are used for breaking refractory materials and linings in e.g. converters, ladles, electric furnaces and blast furnace runners in mainly colder condition.

Use in mining/tunnelling/demolition
Use for scaling in underground mining operations and for breaking out material when enlarging tunnel cross-sections, tunnel rehabilitation and the construction of caverns and cross-cuts.

Advantages:

  • Use in temperature ranges up to 250°C due to additionally modified steelworks version.
  • Additional equipment available to reduce dust exposure when working underground and in tunnels.
  • Can be attached directly to the ripper hook or telescopic boom.

Pneumatic hammer
[Translate to English:] Grafik Pneumatikhammer in rot mit weißer Outline
Pneumatic hammer

Application Metallurgy
Pneumatic hammers are used for breaking out refractory materials and linings in e.g. converters, ladles, electric furnaces and blast furnace runners in hot condition.

Use in mining/tunnelling/demolition
Use for scaling in underground mining operations and for breaking out material when enlarging tunnel cross-sections, tunnel rehabilitation and the construction of caverns and cross-cuts.
Pneumatic hammers are connected directly to the plant air supply network.

Advantages:

  • Use in higher temperature ranges up to 600°C
  • Automatic start and stop function to reduce wear on the hammer and compressor
  • Quick replacement of the chisel by means of a chisel pin

Rotray drum cutter
[Translate to English:] Grafik Fräse in rot mit weißer Outline
Rotray drum cutter

Application Metallurgy
The hydraulically operated drum cutters are used to remove refractory material in blast furnace runners and to profile monolithic refractories.

Use in mining/tunnelling/demolition/construction industry
Used for underground mining work as well as for cutting out material when enlarging tunnel cross-sections, tunnel renovation and the construction of caverns and cross-cuts.

The cutter is equipped with wear-resistant, replaceable cutter teeth.

Advantages:

  • Precise work
  • Can be attached directly to the ripper hook or telescopic boom

Buckets
[Translate to English:] Grafik Tieflöffel in rot mit weißer Outline
Buckets

Buckets pick up loosened or loose material, they are suitable for excavation work at depth, e.g. for pits or trenches, available in various sizes with or without teeth.

Advantages:

  • Can be attached directly to the telescopic boom or via quick coupler
  • Various versions

Hydraulic grapples / shears
Hydraulic grapples / shears / crushers

Application tunnelling/demolition/construction industry
