Custom vacuum lifter with extra safety features

Recently, we supplied a custom-built vacuum lifter, designed in-house for the safe and efficient handling of heavy paper rolls. As paper is naturally porous and not completely airtight, the vacuum level would start to drop almost immediately if the pump stops running in case of a power outage. Even with a large vacuum tank, the load could detach within about a minute. Adding extra safety features solves this issue.

Vacuum lifter specifications

The vacuum lifter is equipped with two suction pads that can handle paper rolls up to 3.500 kg, making the total lifting capacity 7 tons.

The suction and release processes can be completely controlled from the crane cabin. Equipped with a special centering pin and roll detection system, the suction pads ensure fast and precise handling. This exclusive feature was added by our engineers and allows crane operators to work independently without staff assistance at the floor level.

Standard safety features

All our vacuum lifters come equipped with standard safety features, such as a vacuum gauge, green and red signal lights, and an alarm. The red light and alarm are triggered if the vacuum drops below 80%. These features ensure operators are always immediately alerted to any drop in vacuum level.

Extra safety: dual vacuum reservoir (A/B System)

This particular vacuum lifter includes an additional safety feature: a double vacuum reservoir with two completely separate compartments, A and B. Each suction pad is independently connected to either compartment A or B, and both pads have their own vacuum valve for separate control. This setup ensures that if anything happens to one suction pad or load, the other continues to hold the load. The independent control guarantees maximum safety, even in unexpected situations.

This A/B system is available as an optional safety feature on many of our vacuum lifters and can be applied to more suction pads as well:

Extra safety: UPS Emergency power supply

This vacuum lifter is equipped with a built-in UPS, Uninterruptible Power Supply, an integrated battery to maintain the vacuum in case of a power outage.

For paper rolls, which are naturally porous and not completely airtight, the vacuum level would start to drop almost immediately if the pump stops running. Even with a large vacuum tank, the load could detach within about a minute.

With the battery, the pump continues to operate for at least an hour after a power failure. This gives enough time to lower the load safely.

With more than 60 years of experience, we know this as a proven way to handle heavy, porous materials such as paper rolls, where it is crucial to maintain vacuum under all conditions.
