Material handling is an essential part of almost every manufacturing operation.
Workers may need to lift, move, position, rotate, or transfer components throughout the production process.
The problem is not necessarily one heavy lift.
In many workplaces, the bigger challenge is repetition.
A task that is manageable once may become physically demanding when repeated hundreds of times during a shift.
OSHA identifies heavy lifting, bending, reaching, awkward postures and repetitive handling as important ergonomic risk factors in material handling environments.
This is where industrial handling equipment can play an important role.
An ergonomic material handling solution is designed around the interaction between:
Worker + Equipment + Load + Workplace
Instead of asking the operator to adapt to an inefficient handling process, the equipment is designed to make the task easier to perform.
This can involve:
Reducing the force required to move a load
Reducing excessive reaching
Improving the working position
Supporting repetitive lifting
Making loads easier to position
Bringing components into a more accessible working area
Mechanical lifting aids are one example of an engineering approach to reducing physical handling demands.
Industrial manipulators can assist with several common handling tasks.
The manipulator supports the weight of the workpiece, reducing the amount of physical force required from the operator.
The operator can guide the load through the required working area instead of carrying it manually.
The manipulator can help place a component accurately at the required location.
For applications involving orientation changes, the gripping system and manipulator can be configured to allow controlled rotation.
Manipulators can assist operators when repeatedly loading or unloading machines.
This can be particularly valuable when the same handling movement is repeated throughout a production shift.
Imagine an operator handling a 25 kg component.
One lift might not seem particularly demanding.
But imagine performing the same movement:
50 times per shift.
Or:
200 times per shift.
The physical demand accumulates.
Now add:
bending
reaching
twisting
awkward gripping
lifting from below waist height
placing above shoulder height
The task becomes much more demanding.
The goal of ergonomic handling equipment is not necessarily to remove the operator from the process.
Instead, it can allow the operator to control the process without carrying the full physical burden of the load.
One of the biggest advantages of a manipulator is that it can combine machine assistance with human decision-making.
The operator still understands:
where the component needs to go
how the component should be oriented
when it should be released
how the production process is progressing
The manipulator provides the physical assistance.
This makes it particularly useful in production environments where complete automation would be unnecessarily expensive or complicated.
Before selecting a manipulator, manufacturers should evaluate the complete handling task.
Important information includes:
Load
Weight, dimensions, material and center of gravity.
Movement
Lift, move, rotate, tilt, position or transfer.
Frequency
How many handling cycles are performed per hour or shift?
Workspace
Working radius, lifting height and available floor space.
Gripping
How will the load be securely connected to the manipulator?
Environment
Production line, machine shop, warehouse, clean area, or another industrial environment.
A proper assessment can help determine whether a manipulator, vacuum lifter, balancer, crane, hoist, or another material handling system is the right choice.
Ergonomics is not simply about making work more comfortable.
It is about designing the handling process so that people and equipment can work together effectively.
Industrial manipulators can provide mechanical assistance for repetitive lifting, positioning and material handling tasks while allowing operators to maintain control of the process.
For manufacturers looking to improve material handling ergonomics, reduce manual lifting demands, and create more efficient workstations, an industrial manipulator can be an important part of the solution.
