2.9-ton mobile stainless steel gantry crane specifically designed for material lifting needs in cleanroom environments. The main body of the entire machine is made of stainless steel, featuring corrosion resistance, oil resistance, and ease of cleaning. Combined with a mobile caster design, it can flexibly switch workstations within the clean workshop without the need for fixed tracks. It is suitable for clean production scenarios sensitive to dust, rust, and oil stains, helping users improve material handling efficiency while meeting cleanroom compliance requirements.

The main beam, uprights and selected structural components are manufactured from stainless steel. Compared with painted carbon steel, stainless steel avoids paint-coating peel as a potential source of contamination and helps reduce rust-related particle risks when properly selected and maintained.
The crane is available with 304 stainless steel as standard and 316L stainless steel as an option. A mirror-polished or brushed finish can be selected according to cleaning procedures and project requirements.
This mobile gantry crane uses heavy-duty swivel casters with brakes, allowing it to be repositioned on a suitable, level floor without installing a fixed runway or permanent foundation. It can support flexible lifting operations in facilities with multiple workstations or changing production layouts.
Before lifting, position the crane on a firm, level surface and engage the caster brakes. Do not move the crane with a suspended load unless it has been specifically designed and approved for that operation.
The crane can be configured with a cleanroom-compatible hoist and suitable lubrication options to help control particle release and lubricant migration. Stainless steel exposed fasteners are also available to help reduce corrosion-related contamination risks.
The final configuration should be selected according to the cleanroom classification, cleaning procedures, operating frequency and facility requirements.
The gantry structure provides support for lifting tasks and can be equipped with overload protection, upper and lower limit switches, and an emergency stop. The crane should be operated within its rated capacity and in accordance with the manufacturer’s instructions and site safety procedures.

Medical device manufacturing and laboratories: Handling materials and equipment in clean assembly and testing areas.
Cosmetics and personal care production: Supporting equipment handling and maintenance in clean filling and mixing areas.
Need a cleanroom crane for your facility? Contact the KUNFENG technical team to discuss the 2.9T mobile stainless steel gantry crane and its available configurations.
To help us recommend a suitable solution, please provide your required lifting height and span, cleanroom classification, operating frequency, floor conditions and material-handling requirements. KUNFENG can prepare a tailored configuration and quotation based on your project details.
The standard configuration uses 304 stainless steel, with 316L stainless steel available as an option. For environments involving higher humidity, acidic cleaning agents or corrosive substances, 316L may be considered. The material selection should be based on the actual operating and cleaning conditions.
The crane is designed to move between workstations when unloaded. Do not move it with a suspended load unless the specific configuration has been engineered and approved for loaded travel. Engage the caster brakes before lifting.
Yes. Both lifting height and span can be customized based on available headroom, facility layout and process requirements.
The mobile configuration does not require a fixed runway or permanent foundation. It uses caster wheels for repositioning and should be operated on a suitable, level floor.
The stainless steel surfaces are designed to be easy to wipe down as part of routine cleaning. Cleaning agents and maintenance procedures should be checked against the final materials and equipment configuration. Follow the maintenance instructions provided with the crane.
