The SINOLIFT QN series uses a pneumatic airbag to raise a reinforced scissor platform for material positioning in warehouses, workshops, and production lines. Three models cover rated capacities of 500 kg, 1000 kg, and 2000 kg. All reach a maximum platform height of 840 mm, with different platform dimensions and supply pressure requirements.

At a packing bench or assembly station, load height affects how operators reach materials throughout a shift. A low pallet or container may require repeated bending as it empties. An adjustable lift table allows the working level to change with the task, helping keep components, cartons, or other goods within a more convenient reach.

The QN500 Pneumatic Airbag Scissor Lift Table combines foot-operated lift and lower controls, an integrated pressure gauge, a steel platform, and a reinforced scissor structure. The QN1000 and QN2000 extend the capacity choices for heavier applications. Selection should consider the load, its footprint, required working height, and available compressed-air supply rather than capacity alone.

Why use pneumatic lifting at a workstation?

Facilities with a suitable compressed-air network may consider an airbag lift table for repeated height adjustment. Air pressure acts through a reinforced air spring to operate the scissor mechanism. Foot controls let the operator request lifting or lowering without reaching for a separate hand lever during each adjustment.

The lifting drive does not use a hydraulic cylinder, so it avoids hydraulic oil leakage from that mechanism. This can be useful when handling materials near packing surfaces or production equipment. It does not mean the entire installation is maintenance-free, lubricant-free, or automatically suitable for a controlled hygiene environment. Air connections, controls, moving parts, and the platform still require appropriate care.

A lowered height of 230 mm on the QN500 and QN1000, or 240 mm on the QN2000, supports planning for lower work positions. These dimensions should be compared with the incoming load and transfer method. Floor-level access, a ramp, or a pit-mounted arrangement requires its own installation review.

How the QN series supports daily material positioning

At a packing station, the platform can support goods while operators sort items, prepare cartons, or handle materials at different levels. Adjusting the height as work progresses may reduce repeated reaching to low positions. The same principle applies to component preparation and assembly tasks where the quantity or height of material changes.

Start model selection with the complete supported load, including any container or fixture placed on the table. QN500 has a 500 kg rating and a 1220 x 812 mm platform. QN1000 uses the same platform dimensions with a 1000 kg rating. QN2000 provides a 2000 kg rating and a larger 1220 x 1220 mm platform.

The larger platform may help accommodate a wider load, but it also changes operator reach and floor-space requirements. Review how materials will enter and leave the station, where operators will stand, and whether surrounding benches or conveyors create obstructions. A platform that fits the load still needs an accessible working arrangement.

Air supply is another selection factor. The listed pressure is 0.6 MPa for QN500 and QN1000, and 0.45 MPa for QN2000. Confirm required airflow, connection size, air treatment, and pressure regulation before installation. The supplied parameters do not specify air consumption or cycle time, so those details should be requested when matching the table to an existing compressor.

For production-line integration or pit mounting, provide the installation drawing and required transfer height. Check access for servicing, control placement, and clearance around the moving structure. A pit arrangement should be evaluated as part of the complete workstation rather than assumed to follow directly from the table's minimum height.

The listed net weights are 282 kg, 288 kg, and 440 kg respectively. These values matter when planning delivery, placement, and floor support. They do not establish mobility or an operating floor-load rating. Confirm the installation method and supporting surface for the actual site.

Work frequency should be part of the discussion as well. A station that adjusts height once per container has different demands from a process that raises and lowers the platform repeatedly during each batch. Explain the expected number of cycles, time available for each movement, and whether other air-powered equipment shares the supply. These details help establish whether the proposed pneumatic arrangement suits the production schedule.

For an application review, provide the heaviest load, smallest and largest footprints, supporting container, and desired transfer method. Photographs or a simple layout drawing can show obstacles that a platform measurement alone misses. Include the operator's standing position and the location of nearby equipment. This gives the supplier a clearer basis for reviewing the table, controls, and installation, while keeping the final recommendation tied to the actual workplace.
