Mechanical lifting aids are devices or systems that take over or assist with the physical effort involved in lifting, moving, or positioning loads. They are used to reduce the physical strain on workers, increase safety in the workplace, and improve the efficiency of logistics and production processes. In this article, we answer the most frequently asked questions about ergonomic lifting aids: from the different types and legal requirements to choosing the right solution and proper maintenance.
What types of mechanical lifting aids are available?
Mechanical lifting equipment encompasses a wide range of devices, from simple manual tools to complex motorized systems. The most common types include vacuum lifters, hoists, mobile lifters, pallet trucks, pallet inverters electric tugs. The choice depends on the type of load, its weight, the frequency of use, and the available space.
An overview of the main categories:
- Vacuum lifters: suitable for smooth, non-porous surfaces such as panels, glass, and cardboard boxes. They grip the load using suction and enable precise positioning.
- Hoists: mechanical or electric lifting devices used to move heavy loads vertically, often in conjunction with a rail system or crane.
- Mobile lifts: freely movable lifting devices that lift loads vertically and transport them horizontally, ideal for changing workstations.
- Pallet trucks: manual or electric vehicles used to move pallets horizontally over short distances.
- Pallet turners: devices that rotate or tilt pallets, useful for changing packaging or improving ergonomics during loading and unloading.
- Electric tugs: motorized towing devices that move heavy carts or vehicles without requiring physical effort.
Each of these lifting aids is available in several models, designed for specific applications such as pallet handling, box handling, or sheet handling.
When are mechanical lifting aids required in the workplace?
Mechanical lifting aids are required by law when manual lifting poses a demonstrable risk to workers’ health. European Directive 90/269/EEC and the Belgian Code on Well-being at Work require employers to assess risks associated with manual material handling and, where possible, eliminate them by using technical aids.
In practice, the following situations are considered high-risk conditions in which lifting aids are strongly recommended or required:
- Loads that regularly exceed 25 kg for men or 15 kg for women
- Lifting movements that must be performed in an awkward position, such as while bent over or twisted
- Frequent lifting throughout an entire work shift
- Loads with an irregular shape or an unstable center of gravity
- Work environments with limited space to move around or slippery floors
An employer who fails to conduct a risk assessment or to provide appropriate lifting aids when risks are clearly present may be held liable in the event of workplace accidents. Conducting a workstation analysis is therefore not only a best practice, but in many cases a legal requirement.
How do mechanical lifting aids reduce the risk of workplace accidents?
Mechanical lifting aids reduce the risk of workplace accidents by systematically reducing the physical strain on employees’ musculoskeletal systems. They prevent strain on the back, shoulders, and joints, which are the most common causes of work-related injuries in logistics and industry.
The preventive benefits of ergonomic lifting aids are evident on multiple levels:
- Fewer musculoskeletal disorders: by mechanically absorbing the weight of the load, cumulative strain on muscles and joints is prevented.
- Better control over the load: lifting aids such as vacuum lifters or mobile lifters provide a stable grip, significantly reducing the risk of loads falling or tipping over.
- Reduced fatigue: when employees have to exert less physical effort, they remain alert for longer, which reduces the risk of errors caused by inattention.
- Standardized work methods: The use of lifting aids requires a consistent, ergonomically sound approach, which limits improvisation and risky behavior.
In addition to the direct safety benefits, a lower number of workplace accidents also leads to reduced absenteeism, lower replacement costs, and higher overall productivity on the job site.
What is the difference between a vacuum lifter and a hoist?
The main difference between a vacuum lifter and a hoist lies in the way the load is held and moved. A vacuum lifter grips the load by creating a vacuum on its surface and is ideal for smooth, flat materials. A hoist uses mechanical or electrical power to lift a load vertically via a hook or attachment point, regardless of the surface.
Vacuum lifter: precision for flat loads
A vacuum lifter works by placing a vacuum pad against the surface of the load. The negative pressure provides a secure, non-contact grip without damaging the load. This makes vacuum lifters particularly suitable for cardboard boxes, glass panels, metal sheets, and other smooth materials. They offer a high degree of precision when positioning and rotating loads.
Hoist: Versatility for Heavy-Duty Lifting Tasks
A hoist is a lifting device that lifts loads vertically using a chain, cable, or belt. Hoists are used when loads are too heavy, too irregularly shaped, or too rough for a vacuum lifter. They are versatile and work well in combination with rail systems or gantry cranes. The disadvantage is that a hoist is generally less precise when positioning loads than a vacuum lifter.
How do you choose the right lifting aid for your application?
You should choose the right lifting aid based on five criteria: the type of load, the maximum weight, the frequency of the lifting operation, the available space at the workstation, and the required precision during placement. There is no one-size-fits-all solution; the optimal choice always depends on the specific situation.
Follow these steps to make the right choice:
- Analyze the load: What are the shape, weight, surface area, and fragility of the object to be lifted? Boxes, bags, drums, rolls, and sheets each require a different approach.
- Assess the workspace: How much space is available? Are there any obstacles, changes in floor level, or unusual floor coverings?
- Determine how often it will be used: for occasional use, a simpler manual device may suffice; for frequent use, an electric or motorized system is more efficient and safer.
- Involve the users: employees who work with the tool on a daily basis have valuable insights into practical challenges.
- Test before buying: Have employees test the lifting aid with their own equipment before making a final decision.

How do you properly maintain mechanical lifting aids?
Mechanical lifting equipment should be properly maintained through a combination of daily visual inspections, periodic preventive maintenance, and the timely replacement of wear parts. Proper maintenance extends the equipment’s service life, ensures user safety, and prevents unexpected production downtime.
The key maintenance principles are:
- Daily inspection: Before use, check the visible condition of the equipment: cables, hoses, suction cups, connections, and the hydraulic system. Report any abnormalities immediately.
- Periodic inspection: Have the appliance inspected regularly by a technician in accordance with the manufacturer’s instructions and legal inspection requirements.
- Lubrication and cleaning: Moving parts must be lubricated regularly; dirt and dust can interfere with the operation of sensors and vacuum pads.
- Keep records: Record all inspections, repairs, and replacements in a maintenance log. This is not only a best practice, but may also be required by law.
- User training: Make sure that everyone who uses the device knows how to identify and report minor issues.
A maintenance contract with a specialized supplier offers added peace of mind: scheduled maintenance is never overlooked, and technical issues are resolved quickly. More information about service and maintenance will help you determine the right approach for your situation.
