Workplace accidents can occur in all types of fields, and training to prevent accidents from happening is ofutmost importance. Providing safety training increases the awareness of safety of each individual operator andprevents workplace accidents.

there are apprehensions of decreased sensitivity to danger among less experienced employees. That is why safety
training is so important for new and less experienced employees.

As society ages, so does the age of operators, and we can expect more accidents and injuries among older employees. Unlike workplace accidents among employees with little experience, accidents leading to injury among older
employees are often caused by decreased physical capacities. Safety training for older employees helps increase
their awareness of their decreased physical abilities and offers a reminder on the importance of safety.

Accidents among highly experienced expert employees are often the result of human error due to old habits andoverconfidence. Failure to check for safety before starting operations, improper operation of machinery, carelessbehavior, mishandling of machinery, getting caught in machinery while cleaning it and other cases of human error
can happen to anyone, not only less experienced or older employees. It is important to always remain aware ofsafety to prevent accidents caused by old habits and overconfidence. Providing safety training periodically canincrease awareness of safety and reduce the risk of human error.

When the chain is rotating at low speed, the danger is not as obvious.

Regardless of the apparent speed, rotating objects have an extremely high force.
When pinched in a part that is rotating at low speed, the piece of wood breaks easily. Whenperforming cleaning or maintenance, never put your hands into a machine that is rotatingeven if the machine is rotating at low speed.

■ Functions

Equipped with speed setting switch
The speed of rotation of the chain or V-belt can be set in four steps, from low speed to high speed.
By changing the speed, users can experience the relationship between the apparent risk and the actual torque.

is removed without first releasing the cylinder's residual pressure.

With frame■ Description of the device
This device allows users to experience the danger of air pressure when a stopper is removed without releasing the residualpressure at the time of air cylinder impact. Users can also learn how the operating characteristics of air cylinders differ
according to the solenoid valve and the dangers of air cylinder operation.

Teaching the operating characteristics and dangers of air cylinder operation
Users can learn how the operating characteristics and dangers of air cylinder operation
change according to the solenoid valve when the piping is connected in different ways.
Single solenoid valve
The air cylinder can only advance or retreat, and cannot stop immediately.
When the power is turned off, the valve status changes and the air cylinder may operate.
Operation can be prevented by turning off the air pressure source.

Double solenoid valve, 2 positions
The air cylinder can only advance or retreat, and cannot stop immediately.
Air pressure continues to be supplied even when the power is turned off, and the air cylinder
operates when the stopper is released.
Operation can be prevented by turning off the air pressure source.

Double solenoid valve, 3 positions, closed center

Air cylinder operation is restrained by changing the piping.

1046

There are three statuses, advance, retreat and stop, and the air cylinder can be stopped atonce.
The air cylinder operates when the stopper is released, even if the power is turned off and theair pressure source is cut off.
To be sure the air cylinder does not operate, both the power supply and air pressure sourcemust be cut off and the residual pressure must be released.
