# Press Safety Inspections and Press Retrofits

Pohlann modernises and inspects press brakes, mechanical presses and hydraulic presses – from initial assessment to renewed control and safety systems.

## Safety Inspections

Inspection of presses, protective devices and safety functions, including stopping-time measurements, safety distances and assessment of identified defects.

The result is clear, legally robust documentation with defined measures for safe continued operation.

## Press Retrofits

Modernisation of existing presses when the mechanical structure and basic machine substance are worth retaining. Depending on the machine, this can include renewal of controls, safety systems, control cabinet, operator interface and protective devices up to a comprehensive technical overhaul.

## Press Types

### Press Brakes
Modernisation and safety inspection of press brakes from different manufacturers and years of manufacture.

### Mechanical Presses
Inspection and retrofit of eccentric and other mechanical presses with a focus on control sequences, protective devices, stopping behaviour and safety technology.

### Hydraulic Presses
Safety inspection and modernisation of hydraulic presses – from control and safety systems to hydraulic functions, protective devices and operating concepts.

## Typical Starting Points

- obsolete control or safety technology
- spare parts that are difficult or impossible to obtain
- recommissioning after a long period of inactivity
- verification of protective devices or safety distances
- modification or integration into existing production systems
- sound mechanical structure where full replacement would not be economical
- defects identified during an inspection that require a sound technical solution

## Selected Projects

- **Placke HQPBM4 – press brake:** comprehensive retrofit with Delem CNC control, Fiessler safety control and AKAS safety system.
- **HERA COP 160 t / 6 m – press brake, Spain:** replacement of a defective, obsolete Cybelec control with a modern Cybelec system.
- **IMS eccentric press – mechanical press:** renewal of machine and safety controls, control cabinet and operator interface plus safe integration into an automated production system.
- **Müller Weingarten 250 t – hydraulic press:** comprehensive recommissioning with modern control, safety and hydraulic technology.

## Press Retrofit Scope

- machine and safety controls
- Cybelec or Delem CNC controls for press brakes
- control cabinet
- HMI and operator interface
- switches, sensors and operating elements
- protective devices, light curtains, guard doors and two-hand controls
- drive-system adaptations
- hydraulic adaptations with specialised partner companies
- electrical drawings and technical documentation
- testing and validation of safety functions

## Safety Inspection and Documentation

Safety inspections can be carried out as an initial inspection after modification, installation or recommissioning, and as recurring inspections. Depending on the press, the inspection includes the mechanical, electrical and hydraulic condition, safety controls, emergency stop, protective devices, interlocks, light curtains, two-hand and foot controls, stopping times and safety distances.

Results, measured values and identified defects are documented clearly and traceably.

## Project Process

1. Assess the machine and starting point
2. Plan the technical solution
3. Implement the retrofit or corrective measures
4. Test and document
