Semi-Electric Roll Lifter with Pneumatic Expanding Mandrel for Roll Handling
Semi-Electric Roll Lifter with Pneumatic Expanding Mandrel & 90° Rotation
Product Overview
TheSINOLIFT Semi-Electric Roll Lifter with Pneumatic Expanding Mandrel is a customized roll handling solution designed for the safe lifting, positioning, gripping, rotating, and lateral adjustment of heavy roll materials.
The unit combines manual travel, electric lifting, pneumatic internal gripping, powered 90° rotation, and electric lateral shift, allowing operators to position rolls accurately during loading, unloading, material transfer, and production line changeovers.
With a rated load capacity of 300 kg, the lifter is particularly suitable for applications where rolls must be securely supported from the inner core and precisely aligned with production equipment.
The configuration can be customized according to roll dimensions, core size, load weight, lifting height, working space, and production requirements.
Key Features
Pneumatic Expanding Mandrel
The expanding mandrel is inserted into the roll core and pneumatically expanded to create secure internal gripping and stable roll support during lifting and positioning.
Electric Lifting
Powered lifting reduces manual effort and provides smooth vertical positioning. Multi-speed jog control with stepless speed adjustment allows more precise alignment with machinery and workstations.
Powered 90° Roll Rotation
The mandrel can rotate the roll electrically by up to 90° upward, allowing the operator to change roll orientation for loading, unloading, or process requirements.
Electric Lateral Shift
The lifting assembly provides 50 mm left and 50 mm right lateral adjustment, giving a total side-shift travel of 100 mm for fine positioning.
Manual Travel
The truck is manually pushed, making it suitable for controlled short-distance movement within production areas and warehouses.
Reinforced Straddle-Leg Design
The wide support-leg structure improves stability while allowing the lifter to approach pallets, production machines, racks, and roll-handling stations.
Typical Applications
This customized roll lifter can be used for handling a wide range of industrial roll materials, including:
Lithium battery electrode rolls
Separator and film rolls
Paper rolls
Flexible packaging rolls
Printing materials
Textile rolls
Nonwoven rolls
Plastic film and converting materials
It is suitable for battery manufacturing, packaging, printing, textile, film processing, converting, warehousing, and other roll-handling applications.

How It Works
The pneumatic expanding mandrel is inserted into the center core of the roll and expanded to secure the load internally.
The electric lifting system then raises the roll to the required working height. Operators can use the powered rotation function to turn the roll by up to 90°, while the electric lateral shift provides fine left-right adjustment for accurate alignment.
This combination makes the unit especially useful when rolls must be positioned precisely beside production machinery or transferred between different process stages.
Why Choose This Configuration?
Instead of gripping the outside surface of the roll, the pneumatic expanding mandrel supports the material from the inner core.
This helps provide:
Secure internal roll support
Reduced contact with the roll surface
More accurate positioning
Easier orientation adjustment
Controlled loading and unloading
Better compatibility with machine-side roll handling
Customized to Your Roll
This model is supplied as a customized roll handling solution.
Final specifications can be adapted according to:
Roll diameter · Roll width · Roll weight · Core inner diameter · Core material · Required lifting height · Rotation angle · Lateral adjustment · Pallet dimensions · Machine interface · Workspace layout
For the most suitable configuration, customers are recommended to provide the roll dimensions, weight, core specifications, required handling height, and application photos or drawings before production.
