3.5 The advantages of the design
Standard design:
- Vacuum tank.---- When the power failure in suddenly, the pad always can holding the sheet not falling down less than 30 minutes and more.
- Adjustable pad/beam-----Every two pads are installed on the two sides of the cross beams, each cross beam is moveable on the main beam, and each suction pad is also moveable on the cross beam, which can ensure a same equipment can handling the different sizes metal sheet.
- More pad design to keep balance and safety handling-----Multipoint suction point can ensure the metal sheet high level not run-off the straight when handling the metal sheet.
- Buzzer and warning light units and vacuum pressure switch ----- in case of a power failure or vacuum leakage or fails to reach the set pressure, warning unit can control the red warning lights on, At the same time a buzzer sounded, Prompt operator treatment in time.
- Ball valve control pad in individually------ Each suction pads are equipped with manual ball valve control opening and close which can ensure a same equipment can handle various specifications plate.
- Spring cushion---- Suction pad rod up and down each be equipped with a spring cushion, When the plate is uneven, The spring effect buffer action, can make the suction pad strength evenly , so as to ensure suction and lifting the safe and reliable.
- Safety factor---There are 2.0 times safety factor in horizontal
Special advantages
- Vacuum pump intermittent start-up (Energy saving, extend the life of the pump)----When vacuum reaches to the specified pressure, vacuum pump automatically stops to achieve energy saving; when vacuum pressure is insufficient, it automatically restarts to achieve vacuum compensation.
- Rotatable design of sucker head-----Especially for curved plate, better suction and handling
