Stationary scrap shears with side compactor have become an integral part of the modern scrap processing and recycling industry. These robust machines play a key role in the efficient compaction and shearing of a wide range of scrap materials, including solid structural steel, rebar bales and heavy mixed scrap. Scrap processing companies, recycling companies and the steel and foundry industries benefit equally from the stationary scrap shears from Oberländer Recycling Maschinen GmbH, which impress with innovative technology, precise cutting power, longevity, high energy efficiency and minimal maintenance.
Stationary scrap shears – the technological basics
The technology behind stationary scrap shears has evolved over the past few decades. At Oberländer Recycling Maschinen GmbH, the focus is on longevity, reliability, low maintenance and efficiency. The focus is on the column guide of the mobile shear slider, which was successfully introduced by Mr. Werner Oberländer more than 65 years ago. This design ensures that the slider guiding of the scrap shear do not come into contact with scrap or other contaminants, reducing wear to a minimum and maintaining shearing precision for years to come.
Technological advantages:
- Minimized wear: Since the guides do not come into direct contact with the scrap and their fines, wear is drastically reduced.
- Stability of the cutting tolerances: Precise adherence to the cutting tolerance between the upper and lower shear blades is guaranteed over long periods of time without the need for adjustment.
- Ease of maintenance: Compared to other systems, such as linear guides, the Oberländer system does not require regular adjustments, thus reducing operating costs.
Robustness and weight – a quality feature
The stationary scrap shears with side compactors from Oberländer are characterized by their torsion-resistant welded construction, which gives them a particularly high weight. This weight contributes significantly to the stability and stability of the machines, which is an important advantage over lighter models. The solid construction also means that the machines can be set up on a foundation without being firmly anchored. This not only reduces installation costs, but also the time required for commissioning.
Advantages of the robust welded construction:
- High stability: Even under intensive operation, the machine remains stable and safe.
- No anchoring required: The machines can be set up without complex anchoring, which significantly reduces installation costs.
- Long service life: The robust construction ensures that the stationary scrap shears work reliably for many years and do not lose their performance even with intensive use.

Hydraulic performance – efficiency at the highest level
A key feature of modern stationary scrap shears is the sophisticated hydraulic system, which not only provides precise control but also increased efficiency. Oberländer's machines use an innovative hydraulic system that is equipped with power-controlled double pumps that produce minimal delivery volumes when idling. This reduces energy consumption and helps reduce operating costs. In addition, the hydraulic control enables faster pressing and shearing cycles, which significantly increases the processing performance of the machine.
Hydraulic advantages:
- Energy Efficiency: The power-controlled dual pumps minimize power consumption by only providing maximum performance when required.
- Faster work cycles: Improved hydraulic control allows larger quantities of scrap to be processed in less time, increasing the efficiency of the entire process.
- Less heat generation: Generously sized pipes and optimized pipe guides ensure reduced heat generation, which extends the service life of the machine and increases its reliability.
Automatic lubricators – Reduced maintenance, increased service life
The stationary scrap shears from Oberländer are equipped with monitored, automatic oil and grease lubrication, which continuously supplies all moving parts of the machine with lubricants. This reduces wear and ensures smooth operation for many years. Central lubrication makes the machines particularly easy to maintain and minimizes downtime as no manual lubrication is necessary.
Technical advantages:
- Continuous lubrication of the column guide: The guide of the knife carriage and the hold-down device is automatically supplied with lubricating oil. Since the column guide of the knife carriage is outside the shearing area and does not come into contact with scissor sand like other scissor guides, the Oberländer column guide is the most precise and long-lasting scissor guide on the market.
- Longer maintenance intervals: Thanks to central oil and grease lubrication, the machines need to be serviced less frequently, which reduces operating costs and increases availability.
- Simplified Maintenance: Large reservoirs for lubricants in easily accessible areas make refilling easy and hassle-free.
Side compressor and prefill trough – clear design advantages
One of the most outstanding features of Oberländer's stationary scrap shears is the powerful side compactor, which was specially developed to efficiently compact even large volumes of scrap. This compactor ensures that the scrap is optimally compacted even before cutting, further increasing the efficiency of scrap processing. The mechanically machined press box and the guidance via a constant-speed shaft guarantee even force distribution on the scrap and prevent material jamming.
An additional pre-filling trough not only allows the scrap to be assessed and distributed efficiently over the entire length of the press box, but also increases the productivity of the scrap shear by allowing reloading during the shearing process.
Advantages of the Side Compactor:
- Efficient Pre-Compaction: The side compactor ensures that the scrap is pre-compacted evenly and quickly, which speeds up the entire processing process.
- Even Force Distribution: The synchronous shaft ensures that the forces are distributed evenly across the material, preventing the scrap from jamming.
- Smooth Operation: The press box is designed to allow for jam-free processing of the scrap, minimizing downtime and increasing efficiency.
High automation - low operating costs
Oberländer's stationary scrap shears have a high level of automation to reduce operating costs and increase availability. In order to ensure occupational safety and minimize wear on the scissors, operation and monitoring of large shears is mandatory.
The operating personnel play the crucial role. Finding and retaining experienced employees is a question of working conditions. A simple, user-friendly working environment increases the productivity of the system and reduces the demands on operating personnel.
Examples of ease of use are::
- Comfortable operating chair:: The scrap shears are operated from a comfortable chair with the help of joysticks..
- Air-conditioned, sound-insulated control cabine:: Even under extreme environmental conditions, there is a pleasant working atmosphere inside the control cabin thanks to high-quality insulation and air conditioning.
- Clear monitoring of the installation: : The control cabin is equipped with a large front window that ensures a good view of the press box and the pre-filling trough. A large monitor provides a good overview of the current operating parameters..
- Simple maintenance work:: Central lubrication eliminates the need for unpleasant work processes..
Possible uses of stationary scrap shears
The possible uses of stationary scrap shears are extremely diverse. These machines play a central role in scrap recycling and metal recycling. Stationary scrap cutters are indispensable, particularly in recycling plants, scrap recycling companies and the construction industry.
Typical areas of application:
- Recycling companies: Large quantities of metal scrap are processed here, with stationary scrap shears playing a crucial role in shredding and compacting the material.
- Steel mills and foundries: Smelting companies that specialize in recycling scrap metal use stationary scrap shears to prepare the material for pouring and furnace use.
- Production companies: The steel and metal processing industries often produce metallic residues that are difficult to handle without shredding. Special scissors are the ideal solution for efficiently shredding and compacting the material.
