SINOLIFT has highlighted the CDD20 Electric Adjustable Dual-Arm Stacker, a customized material handling solution developed for the transport, lifting, positioning, and production-line loading of rolls, reels, and other large cylindrical materials.

The CDD20 is designed for working conditions where conventional stackers may not provide suitable support for cylindrical loads. It integrates electric travel, electric-hydraulic lifting, independently powered arm adjustment, V-shaped roll supports, and multiple safety devices into one specialized handling machine.

With a load capacity of at least 2 t, electrically adjustable inner arm spacing from 600 mm to 1600 mm, and a lifting height range of approximately 270 mm to 1900 mm, the CDD20 gives production teams a more adaptable option for heavy roll handling and elevated machine loading.

Background and context

Large rolls and reels are common in film, packaging, paper, and other industrial production lines. These cylindrical materials are difficult to manage with standard flat forks because the load can roll sideways, concentrate force unevenly, or require a support position that changes from one roll size to another.

Production teams also need equipment that can handle both low-level pickup and elevated loading. A roll may be stored close to the floor, transported through a workshop, and then raised to a machine-side loading position. When the roll is large or heavy, this sequence requires stable support, controlled travel, and accurate lifting.

The CDD20 was developed for this kind of non-standard handling requirement. Its two adjustable support arms and V-shaped supporting structure are intended to locate cylindrical loads more securely, while electric travel and dual-cylinder lifting help operators move and raise heavy materials with controlled effort.

Main development

The main technical feature of the CDD20 is its electrically adjustable dual-arm structure. The inner distance between the two support arms can be adjusted from approximately 600 mm to 1600 mm, allowing the stacker to adapt to different roll dimensions, support positions, and production-line loading requirements.

Each arm is driven by an independent motor. This independent control gives operators more flexibility when setting the support position around a specific roll or reel. Keeping the arms properly positioned around the machine centerline also helps support stability during handling.

The arms operate from a minimum height of approximately 270 mm to a maximum height of approximately 1900 mm, with an effective lifting range of about 1630 mm. This allows one specialized handling unit to support pickup, transportation, lifting, positioning, and machine loading in a single workflow.

The lifting structure uses dual hydraulic cylinders and an approximately 1.9 m heavy-duty C-channel mast. This configuration is designed for concentrated loads and wide arm spacing, helping improve lifting stability and load distribution when handling large cylindrical materials.

The source specifications list an overall width of approximately 1870 mm, an overall side length of approximately 1925 mm, a front working area dimension of approximately 1424 mm, and a turning radius of less than 1500 mm. Reference roll data includes an 1100 mm roll diameter and 183 mm roll center diameter.

Key highlights for heavy roll handling

Customer and industry value

For roll production lines, the CDD20 can help reduce unnecessary transfers between multiple handling devices. Material pickup, movement, arm adjustment, lifting, and machine-side positioning can be completed with one specialized unit, which is useful where heavy cylindrical materials must move repeatedly between storage and production equipment.

The electric arm adjustment is valuable for facilities that handle different roll sizes. Instead of relying on a fixed-arm structure, operators can adapt the inner arm spacing to the actual load and support position. This can help customers improve handling flexibility when product dimensions change across batches or production lines.

The V-shaped supports, heavy-duty mast, dual hydraulic cylinders, and reinforced structure are especially relevant when handling large rolls where load stability is central to safe movement. PU wheels support smoother travel, while non-metallic lift guide rollers help reduce the generation of iron particles caused by rolling friction in the lifting system.

Significance for SINOLIFT

The CDD20 reinforces SINOLIFT's ability to develop customized material handling equipment for non-standard industrial loads. Cylindrical materials create challenges that are different from standard pallets, and the CDD20 addresses those challenges through adjustable support geometry, purpose-built roll contact surfaces, and controlled electric operation.

This project also shows how SINOLIFT organizes a custom handling solution around the customer's real workflow. The equipment is not limited to a single fixed configuration; it can be customized according to roll diameter, width, weight, supporting position, required loading height, production equipment structure, and operating conditions.

For customers in film, packaging, paper, reel handling, warehouse transfer, and elevated machine loading, that customization path can be as important as the machine's headline capacity. The right handling solution must fit the load, the aisle, the lifting height, the loading point, and the safety expectations of the production site.

Future outlook

SINOLIFT will continue to support customers who need customized roll and reel handling equipment for heavy cylindrical materials. Future projects can be evaluated according to roll diameter, roll width, roll weight, required arm spacing, loading height, turning space, battery requirements, surface treatment, and safety configuration.

As production lines handle larger materials and more varied roll formats, adjustable equipment will remain important for reducing handling interruptions and improving machine-side preparation. SINOLIFT will keep applying application-based design to special material handling projects where standard equipment is not enough.
