Application Overview

In lithium battery manufacturing, electrode rolls may need to move between staging positions serving coating, rolling and slitting processes. This application example considers a SINOLIFT electric roll material lifting and handling truck for those local transfers, where the roll geometry and the pickup and receiving interfaces match the configured truck.

The truck combines electric travel, electric lifting and a roll core positioning arrangement to support cylindrical material handling. The supplied parameter sheet describes two 8-inch single-arm configurations: one for 600 mm roll length and one for 370 mm roll length. Their listed load requirements differ, so selection must follow the individual configuration and the actual roll rather than a single capacity claim for the whole product.

Application Background and Handling Challenges

Moving an electrode roll between production stages requires a handling method that addresses both its mass and its cylindrical form. The pickup arrangement must support the roll and locate it consistently, while the receiving station must accept it at the required height. Direct manual handling or a transport device without height adjustment may leave additional handling steps at either end of the route.

Roll length also changes the equipment requirement. The supplied sheet associates the 600 mm and 370 mm roll configurations with different rated-capacity entries, even though they share the same listed inner diameter and lifting range. Route width, stopping space and the clearance around the load must be considered alongside those parameters, particularly near production equipment.

The SINOLIFT Handling Solution

The electric truck brings powered travel and powered vertical movement into the same transfer sequence. Variable travel speed from 0 to 5 km/h, with high and low speed switching described in the product copy, lets the operator select travel behavior for the task and available space. The appropriate operating speed depends on the loaded truck, route and equipment instructions.

A roll core positioning shaft and a separate roll positioning device are described for locating the material during handling. Both configurations list a positioning shaft of Ø100 mm with 30 mm depth, and a required roll inner diameter of 203.7 mm. These are distinct dimensions: the complete support and positioning interface must be checked rather than assuming that the positioning shaft alone defines the roll fit.

The truck uses PU wheels and a lithium battery system with a battery level display. A key switch, emergency stop button, built-in charger and anti-crushing and anti-impact protection structures are described in the product copy. These features support operation of the configured truck; the documents do not establish a complete range of optional attachments or a final installation-specific loading interface.

Key Features for This Application

Typical Operating Process

Step 1: Match the roll to the configuration. Verify weight, length, outside diameter and inner diameter against the approved truck specification. Confirm the pickup support, destination height, transfer interface and route before approaching the material.

Step 2: Approach the pickup position. Use electric travel to bring the truck into alignment at an appropriate speed. Set the lifting position for the agreed pickup arrangement and check that the truck and roll have the necessary clearance.

Step 3: Support and locate the roll. Engage the approved support arrangement and use the roll core positioning feature and roll positioning device as specified for the equipment. Confirm that the material is properly supported and positioned before raising it.

Step 4: Lift and transport. Use electric lifting to bring the load to the prescribed travel position, then drive along the prepared route. Select speed according to the floor, visibility, load and equipment instructions.

Step 5: Present and hand over. Align the truck with the receiving station and adjust the roll height electrically. Transfer the roll using the agreed interface and release the positioning arrangement only when the receiving equipment supports it. Clear the truck from the handover area.

This is an application sequence rather than an operating manual. Direct loading onto a production machine requires confirmation of support geometry, access, height reference and the transfer method for that machine.

Practical Application Benefits

Powered travel can help reduce the manual pushing effort associated with moving heavy roll materials between local production positions. Combining it with electric lifting may also reduce the need to use a separate height-adjustment device at a compatible staging or receiving point.

The positioning features give the handling task a defined method of locating the cylindrical load, which may make repeated pickup and presentation easier to coordinate. The value depends on matching the roll and the complete support arrangement, including the receiving interface, before the equipment is put into the process.

Battery level information can help operators plan charging around the transfer workload. Actual operating duration depends on the final battery configuration, load, travel distance and lifting duty; the supplied documents do not provide a verified runtime or measured productivity improvement.

Relevant Technical Specifications

The source identifies two 8-inch single-arm roll trucks by roll length, without separate model codes. The comparison below preserves the supplied capacity qualifiers and configuration differences.

The battery entry contains both an original capacity requirement and a modification note. Confirm the final supplied capacity and charger pairing before selection. The “≥” capacity entries are reproduced from the source and do not establish permission to handle loads above an approved final rated limit. Likewise, the roll diameter entry gives a lower bound; no maximum diameter is provided. Confirm the permissible load, roll envelope and lifting-height reference for the actual configuration.

Selection Considerations

1. 1

   Roll geometry and load. Provide maximum roll weight, length, outside diameter, inner diameter and core details. Select the appropriate 600 mm or 370 mm configuration and confirm its approved load limit and support interface.

2. 2

   Pickup and receiving positions. Share staging and machine interface drawings, required heights and access clearances. Verify the meaning of the listed lifting-height range and how the receiving support takes the load.

3. 3

   Travel route and environment. Provide aisle widths, turning areas, floor condition, gradients and any production-area requirements. Overall truck dimensions and the loaded envelope are needed to check access; they are not supplied in the parameter sheet.

4. 4

   Duty, battery and charging. Describe transfer frequency, travel distance and lifting duty. Confirm the final battery capacity, charger compatibility and charging supply, along with any changes needed for the intended operating environment.
