Frequently asked questions about lifting equipment

What is lifting equipment and why is it important in closed processes?

Lifting equipment is a range of ergonomic lifting systems that provides ergonomic height adjustment in containment workstations. It matters because: (1) it reduces operator fatigue during long shifts, (2) it ensures precise product positioning, (3) it minimises exposure risk through safe higher/lower workstations, (4) it supports GMP compliance.

What are the lift ranges and weight capacities?

Standard: 50–150 cm height. Extended: 80–200 cm height. Load capacity: 50 to 3,000 kg. Both variants adjustable with 1 cm precision and available as heavy-duty versions. Choose based on your workstation dimensions and product weight.

How does the electric control work?

24V/230V DC electric motor with digital display. Operators use hand control or a footswitch for smooth height adjustment. Programmable presets for frequently used positions. Emergency stop mechanism and safety switches included.

Is the lifting equipment GMP-compliant?

Yes. GMP Annex 1 compatible, GAMP 5 validation protocols available. Stainless steel variant suitable for closed pharma processes. Complete training and validation package delivers GMP-dossier-ready documentation.

Can I integrate it with my existing containment system?

Most likely. HECHT lifting equipment is designed for integration with all containment workstations. Contact sales with your current setup — technical support will determine mounting points and adaptations.

How much maintenance does the lifting column require?

Minimal. The electric motor is enclosed and maintenance-free. Annual inspection and calibration recommended. HECHT offers preventive maintenance contracts for complete peace of mind.

How much space does the lifting equipment take up?

Compact footprint: approximately 60×60 cm base. Limited space requirement within closed workstations. The column itself is narrow (ø10–12 cm) for easy integration into existing layouts.

What is the energy consumption?

Low: approx. 100–200W during height adjustment, 0W in standby. Only consumes energy when in use. No permanent power draw — ideal for energy-efficient production lines.

Technology

Lifting devices for big bag positioning and emptying

What are lifting devices?

Lifting devices are specialized hoisting systems used to safely lift filled big bags (FIBCs) and position them in a controlled manner above the connection or unloading station. These lifters are an integral part of modular big bag unloading systems and constitute the first step in a safe, ergonomic, and process-reliable bulk handling process.

Key functions and technical role

1. Safe positioning above the connection point
Lifting devices ensure that big bags are precisely positioned relative to the big bag connection system (such as the LAS-EC or AAS system), allowing operators to establish a stable and safe connection without product loss or the risk of contact with hazardous substances.

2. Supporting the unloading process
By tensioning the big bag during unloading and lowering it in a controlled manner, materials such as powders and granules can flow more smoothly out of the container. This improves throughput and prevents obstructions or irregular material discharge—which is crucial in processes involving fine or free-flowing substances.

3. Enhanced safety and ergonomics
Lifting devices are designed with safety and ergonomic principles in mind. By providing mechanical or electrical assistance during lifting, they reduce the physical strain on operators and significantly minimize the risks associated with manually lifting suspended loads.

Integration into big bag unloading stations

In a complete big bag unloading station from HECHT Technology, lifting devices, together with frames, big bag connection systems, and support tables, form a fully integrated solution for bulk handling in chemical, pharmaceutical, and food applications.

Frames and gantries: provide structural support and stability for the lifting system.
Big bag connection systems (AAS, LAS-EC): ensure a dust-free, secure connection during emptying.
Support tables and unloading aids: facilitate material flow and reduce blockages.

Technical advantages

Process reliability: consistent and predictable material flow, with minimal stagnation.
Operator protection: reduced exposure to dust, hazardous substances, and physical strain.
Compatibility: can be combined with a wide range of HECHT big bag connection systems, including options up to OEB-level high containment.
