Repetitive heavy lifting causes serious, sometimes permanent damage to the musculoskeletal system, with back pain, herniated discs, and joint disorders being the most common consequences. The risks increase as the frequency of lifting rises, the weights become heavier, and the work posture becomes less favorable. This article answers the most frequently asked questions about the dangers of repetitive lifting in the workplace and how you can effectively reduce those risks.
What physical injuries does repetitive heavy lifting cause?
Repetitive heavy lifting causes damage to muscles, tendons, joints, and intervertebral discs. The most common conditions are lower back pain, herniated discs, tendinitis, and problems with the shoulders and knees. These musculoskeletal disorders occur because the body does not have enough time to recover between strenuous activities.
Every time you lift something, the intervertebral discs are under pressure. If that pressure builds up repeatedly without sufficient rest, the discs become worn out and damaged. Over time, this can lead to a herniated disc, in which a disc bulges out and presses on a nerve. The pain associated with this is not only severe but can also radiate to the legs or arms and render employees unable to work for an extended period.
In addition to back pain, shoulder and wrist pain are also frequently reported consequences of repetitive lifting. When workers lift loads with a twisted torso or outstretched arms, the muscles and tendons in the shoulder become overloaded. This can result in chronic pain, bursitis, and even tears in the rotator cuff. These injuries develop gradually and are often not noticed until the damage is already significant.
How much weight is too heavy for the body to lift?
There is no universal threshold for what constitutes “too heavy,” but European guidelines use the rule of thumb that an adult worker may manually lift a maximum of 25 kg under optimal conditions. Under unfavorable conditions—such as a twisted posture, a high lifting frequency, or a significant vertical distance—that threshold decreases considerably.
Factors that lower the safe lifting limit include:
- Lifting at a considerable distance from the body
- Lifting above shoulder height or below knee height
- A high repetition rate, such as more than four times per minute
- Unevenly distributed loads or loads without handles
- Vibrations or an unstable surface
Women, younger workers, and older workers generally have a lower lifting capacity. Lower limits are recommended for them. Furthermore, the cumulative daily load is at least as important as the weight per lifting movement. Someone who lifts relatively light loads all day is at just as much risk as someone who lifts a heavy load occasionally.
Which employees are at the greatest risk?
Employees in logistics, manufacturing, construction, healthcare, and distribution are at the highest risk of lifting-related injuries. Within these sectors, it is primarily employees who manually move, pack, or load and unload goods who are exposed daily to the hazards of repetitive lifting.
In addition to the industry, individual factors also play a role. Employees who have had back problems in the past are more vulnerable to new injuries. The same applies to employees who have received little ergonomic training and therefore use improper lifting techniques. Age is also a factor: as employees get older, their muscles and joints recover more slowly from physical strain.
New employees and temporary workers are a particularly at-risk group. They are often not yet accustomed to the physical demands of the job and are sometimes immediately assigned to strenuous tasks without sufficient training in safe work practices. A structured onboarding process that emphasizes ergonomic practices can make all the difference for this group.
What are the consequences of lifting-related injuries for companies?
Work-related injuries cost companies considerably more than just the direct medical costs. Absenteeism, reduced productivity, staff replacement, and higher insurance premiums are the most tangible consequences. Musculoskeletal disorders have been the leading cause of long-term absenteeism in Belgium and the Netherlands for many years.
Indirect costs are often underestimated. An experienced employee who is sidelined due to a herniated disc or shoulder injury takes their knowledge and routine with them. The colleagues who take over the work become overburdened, which increases the risk of new injuries. This domino effect can disrupt a department for months.
In addition, there are legal and regulatory risks. Employers are legally required to assess and manage the risks associated with manual handling. Those who fail to do so risk fines, liability claims, and damage to their reputation. A proactive prevention policy is therefore not only a moral choice but also a sound economic investment.
How can you reduce the risks associated with repetitive lifting in the workplace?
You can reduce the risks associated with repetitive lifting through a combination of technical aids, organizational measures, and training. The most effective approach eliminates or reduces the manual lifting itself, rather than relying solely on proper lifting technique.
Specific measures that have been proven effective:
- Using mechanical lifting aids: vacuum lifters, hoists, or mobile lifters take over the physical lifting work and drastically reduce the strain.
- Designing Ergonomic Workstations: Ensure that loads are positioned at a comfortable working height to avoid lifting above shoulder level or below knee level.
- Task Allocation and Rotation: Alternate heavy lifting with lighter tasks to limit cumulative strain.
- Training in safe lifting: Teach employees the proper lifting technique, but make it clear that technique alone is no substitute for lifting aids.
- Regular risk analysis: Periodically assess which activities pose the highest risk and prioritize improvements.
The combination of technology and awareness yields the best results. Ergonomic pallet trucks and other mechanical aids not only reduce physical strain but also increase the efficiency of the work process.
When is an ergonomic workstation analysis necessary?
An ergonomic workstation analysis is necessary when employees regularly lift loads weighing more than 15 kg, when there are complaints of back pain or other musculoskeletal disorders, or when absenteeism due to illness in a department is consistently high. An analysis is also recommended when setting up new workstations or following a workplace accident.
The analysis identifies which tasks pose the highest risks, how significant the cumulative workload is per employee, and which technical or organizational measures will be most effective. The result is a concrete action plan, not a general recommendation.
From a legal standpoint, employers in Belgium are required to have a risk assessment conducted for all manual handling tasks. An external ergonomic assessment provides a solid foundation for this and demonstrates that the company takes its duty of care seriously.
