Safety catchers for presses – find manufacturers and suppliers

Safety catchers for presses are safety devices designed to prevent the moving parts of the press from falling downwards in an uncontrolled manner, thereby endangering people or equipment.

They are an essential component of modern press technology and are mainly used in mechanical, hydraulic and pneumatic presses. Their aim is to prevent both accidents and material damage.

Below you will find the function and types of safety catchers for presses, their areas of application and their advantages:

How safety catchers for presses work:

Safety catchers act as a mechanical or hydraulic blockade between the moving part of the press and the fixed machine frame. They intervene automatically as soon as a fault occurs, e.g. loss of pressure, power failure or a mechanical defect.

1. With mechanical safety catchers, the ram is blocked by pawls, wedges or gears.
2. In hydraulic anti-drop devices, non-return valves or locking cylinders ensure that no oil escapes and that the press ram cannot drop.
3. In combined systems, both mechanical and hydraulic elements come together to ensure a particularly high level of safety.

They can be triggered automatically, e.g. when the pressure drops, or manually via an emergency stop system.

Types of safety catchers for presses:

1. Mechanical safety catchers:
   These systems block the ram using fixed, mechanical locks.
   Examples include pawls, ratchet mechanisms or wedge systems.
   They are robust and low-maintenance, but usually only engage after a stroke has been completed (not continuously).
2. Hydraulic safety catchers:
   Locking cylinders or non-return valves are used here to prevent lowering in the event of a pressure drop.
   They are used particularly on hydraulic presses and are active throughout operation.
3. Pneumatic safety catchers:
   These work in a similar way to hydraulic ones, but are based on air pressure.
   They are lighter but less precise than hydraulic systems and are often used on smaller presses.
4. Electronically monitored safety catchers:
   These systems combine mechanical barriers with sensors and control technology.
   They detect potential fault conditions at an early stage and activate the safety device automatically.
   They are typical of modern CNC presses.

Use of safety catchers in presses:

Safety catchers are used in all types of presses:

1. Mechanical eccentric presses
2. Hydraulic presses,
3. Punching presses,
4. Transfer presses
5. Press lines.

They are mandatory or state of the art wherever there are heavy moving machine parts.
In addition to protecting the operating personnel, they also play a role in machine protection to prevent expensive damage in the event of breakdowns.

Advantages of fall protection for presses:

• Personal protection: Prevents life-threatening accidents caused by falling rams.
• Tool and machine protection: Reduces consequential damage and production downtime.
• Automatic function: The safety devices work without operator intervention and react immediately to faults.
• Compliance with standards: They fulfill legal requirements (e.g. Machinery Directive, DIN EN 693 for hydraulic presses).
• Increased productivity: Safety devices often allow presses to be operated at higher speeds without increasing the risk.
• Ease of maintenance: Modern systems are designed for low maintenance and are easy to inspect.

Safety guards for presses are indispensable safety devices. They are mechanically, hydraulically, pneumatically or electronically monitored and prevent the uncontrolled lowering of heavy moving parts. Their use protects people, machines and production processes and is now mandatory in many areas.

Here are the most important aspects to look out for when purchasing fall protection for presses:

Safety catchers for presses are safety-relevant components that make a decisive contribution to the protection of people, machines and production processes. Their selection and procurement must therefore not be based solely on cost considerations, but must also take technical, legal and organizational criteria into account. Professional purchasing ensures that the selected fall protection system not only fulfills legal requirements, but is also optimally suited to the respective machine and its use.

• Important aspects when purchasing fall protection are:
• Firstly, it must be checked whether the fall protection system is compatible with the respective press type (mechanical, hydraulic, pneumatic).
• Differences in size, lifting force and speed require coordinated solutions.
• The weight and dimensions of the ram also play a role.
• A key criterion is compliance with the relevant safety standards, such as the Machinery Directive (2006/42/EC) and specific press standards such as DIN EN 693 for hydraulic presses.
• In addition, the fall protection system must be CE-marked and have a traceable declaration of conformity.
• The fall protection system must be able to safely bear the maximum load of the moving part of the press - even at peak loads.
• A sufficient safety factor is necessary to absorb unforeseen loads, e.g. material faults or malfunctions.
• The reliability and speed of the locking mechanism is important. In an emergency, the safety mechanism must engage immediately and reliably.
• In the case of hydraulic systems, check valves and locking cylinders should be checked in particular, and in the case of mechanical systems, locking pawls or wedges.
• Modern presses are often equipped with electronic safety controls.
• A good safety catchers system can be seamlessly integrated so that fault conditions can be automatically detected and documented.
• Interfaces for emergency stop or safety PLCs are a plus here.
• The manufacturer's reputation and certifications, e.g. ISO 9001, are an indicator of the product's reliability.
• Professional purchasing takes into account references, guarantees and services offered by the supplier.
• Safety catchers must be regularly inspected and maintained.
• Systems with low maintenance requirements and clear inspection documentation reduce operating costs and make it easier to comply with safety regulations. Easily accessible testing facilities are also important.
• A good supply of spare parts and fast service are crucial for long-term operation.
• Suppliers should offer warranties and clear support to minimize downtime.
• In addition to the purchase price, the entire life cycle should be considered.
• Higher investments in high-quality systems often pay off, as maintenance costs fall, downtime is reduced and the service life increases.
• The scope of delivery should include complete documentation (operating instructions, test plans, certificates) as well as training for operating and maintenance personnel. This ensures that the fall protection system is installed, tested and used correctly.

Purchasing safety catchers for presses is a safety-critical and strategic decision. A professional selection takes into account not only technical and legal requirements, but also service, integration, ease of maintenance and cost-effectiveness over the entire life cycle. A careful approach will protect employees and machines in the long term, reduce long-term costs and ensure that operations comply with the law.
