What information is needed before quotation?

For quotation, WOLIFT normally needs load weight, dimensions, material surface, lifting orientation, working cycle, pickup and release position, site space, power or air supply, and whether a crane, trolley or special frame is required.

What materials can Vacuum Tube Lifters for Bags handle?

This product can be configured for paper sacks, woven bags, plastic bags and flexible packages. Final feasibility depends on surface condition, weight, size, leakage, deformation and the required lifting path.

How should the correct model be selected?

Model selection should be based on the actual load weight, workpiece size, lifting height, stroke, operating frequency, safety requirements and site layout. WOLIFT engineers can recommend a suitable model after reviewing the application.

What air supply is required?

Pneumatic equipment should be connected to a stable compressed air supply. The required pressure, air consumption and pipeline arrangement should be confirmed according to the final configuration.

What safety features are available?

WOLIFT vacuum lifting equipment can be supplied with CE compliance and vacuum holding function. The detailed safety factor, alarm, vacuum circuit and control design should be confirmed according to product type and application risk.

Can WOLIFT export and support overseas projects?

Yes. WOLIFT supplies equipment for global export and can provide pre-sales selection support, installation guidance, operation documentation and spare parts support for overseas customers.

Bag compatibility

What kinds of bags and sacks can be lifted?

WOLIFT vacuum tube lifters for bags can be configured for paper sacks, woven bags, plastic bags, valve bags and other flexible packaged goods. The final suction pad and vacuum source depend on bag weight, surface texture, air permeability, deformation and lifting frequency.

WOLIFT vacuum tube lifter for paper sack handling

Paper sacks

Suitable for cement bags, chemical bags, flour bags and other paper sacks with stable contact areas.

Vacuum lifter for woven bag and sack handling

Woven bags

Can handle many PP woven sacks used for grain, rice, feed, fertilizer and bulk material packaging.

Vacuum tube lifter for plastic bag handling

Plastic bags

Useful for plastic film bags and sealed packages when the surface can maintain enough vacuum contact.

Custom suction pad for flexible bag vacuum lifting

Flexible packages

For soft, uneven or mixed-size bags, WOLIFT can design the suction pad around the real product shape and handling route.

Selection note: Highly porous bags, dusty surfaces, loose-filled sacks, leaking seams or severely wrinkled bags should be tested before confirming the final vacuum lifter configuration.

Equipment advantages

Ergonomic vacuum lifting for heavy and frequent bag handling

The WOLIFT bag vacuum tube lifter combines suction, lifting, lowering and release in one operator-friendly system. It helps reduce manual lifting, repeated bending and shoulder strain during bag palletizing, depalletizing, loading and transfer work.

250 kg Model range available for heavy sacks, bulk bags and high-frequency material handling tasks.

Simple control One operator can lift, move, lower and release bags through an easy handle control.

Bag-friendly contact Suction pads can be adapted for paper sacks, woven sacks, plastic bags and flexible packaging.

Faster workflow Improves repetitive palletizing, conveyor-end handling, truck unloading and warehouse transfer efficiency.

FAQ

Common questions about bag vacuum tube lifters

What bags can a vacuum tube lifter handle?

WOLIFT vacuum tube lifters can be configured for many paper sacks, woven bags, plastic bags, valve bags and flexible packaged goods. The key factors are weight, surface texture, air leakage and how much the bag deforms during lifting.

Can the lifter handle porous woven sacks?

Many woven sacks can be handled with the right vacuum source and suction pad design. Highly porous, dusty or loosely filled sacks should be tested before final model selection.

What is the maximum lifting capacity for bags?

The model range can support up to 250 kg. Actual capacity depends on bag surface condition, air permeability, sealing performance, safety factor and working frequency.

Can one operator use the bag vacuum lifter?

Yes. The vacuum tube lifter is designed for one-operator lifting, lowering and release, helping reduce manual handling strain during repetitive bag palletizing and transfer work.

Which industries use vacuum lifters for bags and sacks?

Typical industries include food processing, grain and rice handling, animal feed, fertilizer, chemicals, building materials, logistics warehouses and packaging lines.

Do I need a jib crane or rail system?

Yes. A vacuum tube lifter for bags needs suitable suspension equipment. WOLIFT can match it with a pillar jib crane, wall-mounted jib crane, mobile pillar jib crane or KBK light rail system.
