- The Pneumatic Industrial Manipulator is not an ordinary spreader and cannot be dragged at will; improper operation of any link may affect the stability of the transportation and the status of the equipment.
- Ten items prohibited/not recommended: overloading, standing under the load, hanging the load unattended, moving without confirming the clamping, dragging the workpiece, violent swing, changing the pneumatic circuit without authorization, running with a fault, not unloading before shutting off the gas, and operating by non-trained personnel.
- Do it before use every dayDaily inspection: compressed-air supply, air hose joint, body, handle button, clamp, suction cup, no-load and loaded actions.
- Standard operation does not limit efficiency, but allows the equipment to operate stably within the design conditions.
Pneumatic Industrial Manipulators, pneumatic manipulators, pneumatic balance hoists, vacuum lifters, and matching custom end-effector tooling are widely used for workpiece handling, machine loading and unloading, assembly, palletizing, and assisted transfer. These systems reduce manual-handling demands and improve process consistency, provided that operators follow all safety requirements. This article summarizes common unsafe actions and the corresponding correct practices for operators, team leaders, equipment supervisors, and maintenance personnel.
01Why a Pneumatic Industrial Manipulator Requires Standardized Operation
Pneumatic Industrial Manipulators usually consist of mechanical structures, pneumatic control systems, load balancing systems, operating handles, clamps or vacuum gripping devices. Improper operation of any link may affect the smoothness of handling and the status of the equipment. For example, overloading will increase the burden on the mechanical and pneumatic systems; moving without confirming clamping may cause the workpiece to slip; personnel standing under the load may easily enter the dangerous area; adjusting the compressed-air supply or changing the air path without authorization may lead to abnormal balance, out-of-control movements, or failure of safety protection. The purpose of standardized operation is to make the equipment operate stably within the designed working conditions.
02What actions cannot be done
- Overloading is prohibited: Do not lift workpieces that exceed the capacity of the equipment just for "occasional moving". Overloading will affect the structural stress and the safety margins of clamps, cylinders, and suction cups.
- Personnel are prohibited from standing under the load: Hands, feet or body should not be inserted into areas where workpieces may fall or swing.
- It is prohibited to leave the load unattended: Do not leave the workstation, answer the phone, handle other tasks, or keep the load suspended for a long time when the load is suspended.
- It is prohibited to move the fixture without confirming that it is clamped: Make sure the fixture is in place, the workpiece is stable, and the vacuum or clamping status is normal before moving.
- Do not drag the workpiece: The Pneumatic Industrial Manipulator is used to assist lifting and smooth transportation. Forcibly dragging stuck workpieces and material frames may cause unbalanced loading, impact or surface damage.
- Violent swinging and impact operations are prohibited: Avoid rapid swinging, jerking and releasing, sudden stops and turns, and reduce inertial impact and collision.
- It is prohibited to modify the air path or adjust key components without authorization: The pneumatic circuit, valve group, safety valve, load balancing system and control module should be configured and used according to the plan.
- Operation with faults is prohibited: When abnormal noise, air leakage, slow movement, unstable hovering, abnormal clamping, vacuum alarm or abnormal air pressure occur, the machine should be stopped for inspection.
- It is forbidden to hang the workpiece after turning off the compressed-air supply.: Before shutting down, leaving get off work, or performing maintenance, the workpiece should be stabilized, the fixture should be unloaded, and then the compressed-air supply should be turned off.
- Operation by non-trained personnel is prohibited: Temporary personnel, new employees or outsourcing personnel should receive necessary safe operation training before use.
03What should be checked before correct operation
It is recommended to conduct daily inspections before use every day: check whether the compressed-air supply pressure is normal, whether the pneumatic tubing and joints are leaking, loose, bent or worn; check whether the body is abnormally loose, abnormal noise, or stuck, and whether the operating handle and control buttons are sensitive and reliable. custom tooling should check the jaws, suction cups, compression blocks, positioning parts, connecting bolts and limiting structures; vacuum cranes should confirm that the suction cups are not aged, damaged, or deformed, and that the suction surfaces has no obvious oil, dust or foreign matter; pneumatic equipment should confirm that the no-load and loaded movements are smooth, and that the load does not float or sink abnormally. It should also be confirmed that the transportation path is clear and there is no interference from peripheral equipment, material racks, guardrails, passages and personnel positions.
04List of prohibited/not recommended operations
| operating behavior | Possible risks | Correct approach |
|---|---|---|
| overload use | The stress on the structure increases, the balance becomes abnormal, and the risk of fixture failure increases. | Use according to rated load and program requirements |
| Personnel stands underneath the load | Entering the dangerous area, there is a risk of injury due to falling workpieces | Keep people away from under the load and within the swing range |
| The load is left unattended | Risk of workpiece instability, pressure relief or malfunction | Operators are not allowed to leave their posts when the workpiece is suspended in the air |
| Moving the fixture without confirming that it is clamped | Workpiece slips, tilts or falls | Confirm that clamping, vacuum gripping or positioning are in place before moving |
| Drag the workpiece | The manipulator is unbalanced, the fixture is impacted, and the workpiece is damaged. | First eliminate the cause of the jam, and then move according to the normal path. |
| Swing wildly | The workpiece collides with equipment or personnel, increasing inertial impact | Push and pull smoothly, turn and position slowly |
| Changing the air path without authorization | The compressed-air supply pressure is abnormal and safety protection fails. | Adjust after confirmation by the manufacturer or professional |
| Operating with faults | The fault expands and affects the safety of equipment and personnel. | Shut down for inspection and eliminate abnormalities before use. |
| Do not leave the workpiece loaded after shutting off the compressed-air supply | Risk of workpiece sinking or fixture failure | Place the workpiece stably first, then shut down the machine and cut off the air. |
| Operation by non-trained personnel | If you don’t understand the safety boundaries, the risk of misoperation is high. | After passing the training, operate according to the procedures |
