Ergonomics in the assembly workstation: Recognizing and reducing strain
Manually lifting and holding heavy loads is one of the most common causes of physical strain in production. Early detection of this strain can prevent downtime and subsequent costs.
This guide shows how to assess physical strain in the workplace and reduce it using lifting aids. It provides factual guidance, not a sales pitch.
THE PROBLEM
WHY THE EXAM IS MANDATORY
It's not just the weight itself that matters. The interplay of several factors is crucial: the frequency of lifting, posture, grip conditions, and the duration of the activity.
A moderate load, lifted many times a day in an awkward position, can be more stressful than a single heavy lift. That's precisely why strain cannot be defined by a single kilogram limit.
load weight
Height of the load and distribution of the weight.
posture
Bending, twisting, overhead work, reach.
frequency
Number of lifting operations per shift.
Grip and duration
Tangibility of the load and length of the activity.
THE SOLUTION
HOW LIFTING AIDS PROVIDE RELIEF
A lifting aid absorbs the weight of the load, allowing the employee to guide it with virtually no effort. Pendulum-free systems also enable smooth, controlled movement without awkward compensatory postures.
A lifting aid thus reduces the strain on all four factors simultaneously: The weight is absorbed, repeated lifting is eliminated, the posture remains upright, and the load can be gripped securely.
FAQ / Q&A
FREQUENTLY ASKED QUESTIONS
01 From what weight does a lifting aid become useful?
There is no fixed limit. The crucial factor is the interplay of weight, frequency, and posture. Even with moderate loads at high frequencies, a lifting aid is worthwhile.
02 How can stress be objectively assessed?
Established methods such as the key indicator method evaluate weight, frequency, posture and other factors to create an overall assessment.
03 Does ergonomics also pay off economically?
Yes. Fewer load-related failures, lower error rates, and higher cycle time reliability directly impact productivity.
04 Which Zeilhofer solution suits my workplace?
That depends on the load, type of movement, and available space. Lifting axes, manipulators, and hoists cover different requirements.
