3.3 System Characteristics Description
3.3.1 Design Standards
The equipment strictly adheres to the European CE standard EN13155:2003, designed based on the American Society of Mechanical Engineers (ASME) standard B30-20-2006 and the German standard UVV18, with a primary design index higher than the mentioned standards.
(1) Safety factor: Main design greater than 2.0. The calculated vacuum system pressure is 60%. The maximum achievable actual pressure is 85% vacuum. The pressure setting on one side is 40% vacuum.
(2) Lifting arm limits
Calculation of lifting arm limits (Minimum thickness)
Minimum plate thickness: 15mm
Maximum lifting arm length: 2184mm
Refer to the following diagram for more details.
Note: If the lifted plate exceeds the maximum allowable value, it may cause irreversible permanent deformation to the lifting arm.
3.3.2. Suction Force Calculation
Diameter 230mm
Each suction pad has a maximum theoretical suction force in the horizontal direction = Effective surface (Theoretical area * Coefficient) * Calculated pressure (0.6 bar) = (0.115*0.115*3.14)*0.6*10000 = 249N, approximately 249Kgf.
According to the double safety factor, the actual allowable suction for each pad is 249/2 = 124Kgf, with 6 pads the total suction force is 700Kgf.
Note: The maintenance force mentioned above is calculated at 60% vacuum pressure, the system’s maximum vacuum reaches up to 85% under normal working conditions.

The equipment includes the following main components:
- Vacuum pump
Choosing the German Becker brand, the oil-free vacuum pump has an air-cooled impeller, a gas handling speed of 8m3/hour and a maximum vacuum level of up to 85%, saving materials, compact, lightweight, maintenance-free…
The vacuum pump with an air-cooled impeller does not use oil, connects to a 220V, 3-phase power source, and can create a vacuum. This is the core component of the vacuum system, with a maximum vacuum level of 85%.
- Vacuum suction pad
Suctions the workpiece surface, with rubber contacting the workpiece to ensure no damage to the workpiece surface.
- Vacuum filter
Removes dust and suspended objects from the air, ensuring the longevity of the vacuum pump.
- Vacuum gauge
Displays the vacuum level for the operator, ensuring safety.
- Vacuum pressure switch
A diaphragm pump, when the vacuum pressure is insufficient, the switch will send an electrical signal to the warning system.
- Manual slide valve
Cuts off the operation of the pump and suction pad from the airflow, a safety lock to prevent accidental operation.
- One-way vacuum valve
In case of a power failure, it will automatically cut off the vacuum pump and air channel, locking the vacuum energy of the vacuum tank, providing enough time to maintain pressure, ensuring that the workpiece does not drop suddenly.
- Manually adjustable ball valve
Opens and closes the vacuum pump and suction pad by hand, allowing for easy maintenance.
- Warning light
When the suction force of a suction pad is insufficient, the corresponding warning light will indicate.
3.5 Advantages of the design
Standard design:
1) Vacuum tank: In case of a sudden power failure, the suction pad can still hold the plate without dropping it for 30 minutes or more.
2) Adjustable beam/suction pad: Two suction pads are installed on two sides of the crossbeam, each crossbeam can move along the main beam, and each suction pad can also move along the crossbeam, ensuring that with the same equipment, it can handle various plate sizes.
3) Suction pad design for balance and operational safety: The multi-point suction pad can ensure better plate balance even when not moving in a straight line.
4) Bell and warning light system, vacuum pressure switch: In case of power failure, vacuum leakage, or failure to reach the specified pressure, the warning system can turn on a red light, and the buzzer will sound to allow the operator to take timely action.
5) Suction pad controlled by individual ball valves: Each suction pad is equipped with a ball valve for manual opening and closing, ensuring that the same equipment can handle plates of various specifications.
6) Spring shock absorber: The push rod for raising and lowering the suction pad is equipped with a spring shock absorber. If the plate is not flat, this spring helps reduce vibration, making the suction pad more secure and ensuring safer lifting and lowering.
7) Safety factor: The safety factor is 2.0 times in the horizontal direction.
Special Advantages
8) Intermittent vacuum pump operation (saves energy, prolongs pump life): When the vacuum reaches the specified pressure, the vacuum pump will automatically stop to save energy. When the vacuum pressure is insufficient, the pump will automatically operate again to compensate for the vacuum.
9) Rotatable suction head design: Particularly for curved plates, it will suck and process better.
10) Special suction pad design: Very low replacement cost, easy removal of the suction pad gasket helps reduce costs when moving.
11) Surface treatment: Using high-quality steel material, welded parts are ground flat, the main structure uses heat-resistant paint, the surface of the beam can be adjusted after polishing, electro-plating treatment helps prevent rusting in humid environments.
3.6 Operating instructions for the vacuum lifter
3.6.1 Plate suction position
Control the crane to move the vacuum lifter above the metal plate and close to the top surface.
3.6.2 Suck the plate
Push the manual control valve slide forward, the suction pads will automatically suck the plate. When the vacuum level reaches the requirement, the green light will turn on, and the alarm bell will stop ringing, indicating the lift is ready.
3.6.3 Move the plate
Control the crane to move the plate to the desired position.
3.6.4 Release the plate
Press the safety button on the manual control valve slide, pull the push-pull valve back, and the plate will be released.
3.6.5 Control the corresponding suction pad
When the plate length is shorter than the distance between the outermost suction pads of the two clusters, turn off the manual control ball valve on each suction pad, isolating it from the vacuum system’s air flow to prevent vacuum leakage.
