CDD20 Electric Adjustable Dual-Arm Stacker

Product Description：

The CDD20 Electric Adjustable Dual-Arm Stacker is a customized material handling solution designed for the transport, lifting, positioning, and production-line loading of rolls, reels, and other large cylindrical materials. Developed for applications where conventional stackers may not provide suitable support for cylindrical loads, the CDD20 integrates electric travel, electric-hydraulic lifting, independently powered arm adjustment, and V-shaped roll supports into one specialized machine.

The inner distance between the two support arms can be electrically adjusted from approximately 600 to 1600 mm, allowing the machine to accommodate different roll dimensions, support positions, and loading requirements. Each arm is powered by an independent motor for flexible positioning. The V-shaped supporting structure helps locate cylindrical loads securely and reduces the risk of rolls moving or rolling sideways during handling.

The dual arms can operate from a minimum height of approximately 270 mm to a maximum height of approximately 1900 mm, allowing the machine to perform both low-level pickup and elevated machine-loading operations. A heavy-duty C-channel mast of approximately 1.9 m combined with a dual-cylinder lifting system provides enhanced stability when lifting large and heavy rolls.

The CDD20 features electric travel and a lithium battery power system, together with multiple safety features including an emergency stop, mechanical limit protection, travel limit switches, electrical limit protection, a safety wire mesh guard, and a transparent PC protective panel.

As a non-standard customizable product, the CDD20 can be configured according to the customer's actual roll dimensions, load requirements, production equipment, loading height, and specific operating conditions.

Product Features：

1. 600–1600 mm Wide Electric Arm Adjustment

The inner distance between the two support arms can be electrically adjusted from approximately 600 to 1600 mm. This wide adjustment range enables the stacker to accommodate different roll sizes and support positions, providing significantly greater flexibility than a fixed-arm handling solution.

2. Independently Powered Dual Arms

Each support arm is driven by an independent motor and can be positioned according to the actual handling requirement. This independent adjustment system provides greater flexibility when working with different roll dimensions and production-line layouts. Keeping the arms properly positioned and symmetrical around the machine centerline helps maintain load stability during handling.

3. 270–1900 mm Lifting Range

With an arm height ranging from approximately 270 mm to 1900 mm, the CDD20 can handle both low-level material pickup and elevated production-line loading. Material pickup, transportation, lifting, positioning, and machine loading can therefore be completed with one specialized handling unit.

4. V-Shaped Supports for Cylindrical Loads

The support arms feature a V-shaped design specifically suited to rolls and cylindrical materials. The V-shaped supporting area helps locate the load and reduces the possibility of unwanted rolling or lateral movement during transportation and lifting.

5. Heavy-Duty C-Channel Mast and Dual Cylinders

The machine uses a heavy-duty C-channel mast combined with a dual-cylinder lifting structure. This configuration is designed for applications involving concentrated loads and wide arm spacing, helping improve lifting stability and load distribution when handling large rolls.

6. ≥2 t Heavy-Duty Capacity

Designed for a load requirement of 2 tonnes or more, the CDD20 provides a specialized solution for handling large and heavy rolls and other cylindrical industrial materials.

7. Electric Travel with Stepless Speed Control

The electric travel system provides 0–5 km/h stepless speed control, allowing the operator to adjust travel speed according to aisle conditions, load status, and the final loading position. This provides greater control when transporting heavy cylindrical materials around production areas.

8. Multiple Safety Features

The CDD20 incorporates an emergency stop, mechanical limit protection, travel limit switches, electrical limit protection, safety wire mesh guarding, and a transparent PC protective panel. The overall structure is also designed with stability under fully loaded lifting conditions in mind.

9. Non-Metallic Lift Guide Rollers

Non-metallic guide rollers are used in the lifting system to help reduce the generation of iron particles caused by rolling friction, making the machine suitable for industrial environments where production cleanliness is an important consideration.

10. Customizable for Special Applications

The CDD20 is not limited to a single standard configuration. The machine can be customized according to roll diameter, width, weight, supporting position, required loading height, and the structure of the customer's production equipment, providing a more application-specific handling solution.

Applications：

Roll Production Line Loading

The CDD20 is suitable for picking up, transporting, lifting, and positioning rolls at production equipment. The electrically adjustable arms and wide lifting range allow the machine to adapt to different roll dimensions and machine-loading positions.

Film and Packaging Roll Handling

It can be used for transporting plastic film rolls, packaging film rolls, and other rolled packaging materials between storage areas, production lines, and processing equipment. The V-shaped arms provide stable support for cylindrical loads during movement.

Paper Roll and Reel Handling

The machine can handle paper rolls and other large reel-type materials. Its 600–1600 mm electric arm adjustment allows the supporting positions to be adapted to different roll dimensions.

Industrial Roll Warehouse Handling

The CDD20 can be used to transport rolls between warehouse areas and production stations. By integrating electric travel, arm adjustment, and lifting functions into one machine, it can reduce unnecessary material transfers between different handling equipment.

Elevated Machine Loading

With a maximum arm height of approximately 1900 mm, the CDD20 is suitable for production equipment with elevated loading positions. Rolls can be transported, raised, and positioned before being delivered to the required loading point.

Customized Cylindrical Material Handling

For cylindrical materials with special dimensions, weights, supporting positions, or loading requirements, the CDD20 can be customized according to the actual application, allowing the handling equipment to better match the customer's materials and production process.
