Product Details
Small steering wheel
Ergonomically designed tilt angle adjustable small diameter steering wheel (Φ300) with good feel and reduced operator fatigue intensity.
Intelligent design
Based on advanced ergonomic design, integrated control valve type operating handle, electrical switches centralized layout, for fast and convenient manipulation.
Side roller wheel
The side roller is positioned above the main roller. When the fork is raised to a higher position, the left-right shaking amplitude is greatly reduced, which improves the stability of high-position operation and reduces the bearing failure rate.
Digital dashboard
Using digital stepping instrument panel and CAN bus communication technology, display is more intuitive, with high man-machine interaction, enabling real-time monitoring of the machine status.

Special Forks
Optimize your material handling with our range of specialized forks. These attachments are designed to safely and efficiently handle unique loads, such as coils, drums, or blocks, enhancing both productivity and application versatility.

Weigher System
Keep track of load weight instantly and accurately with the integrated weighing system. This feature enhances operational safety and efficiency by preventing overloads and streamlining material handling workflows.

Spark Arrestor
Operate with confidence in sensitive environments. The spark arrestor effectively contains hot particles, significantly reducing fire risk when working near combustible materials or in dry, high-risk areas.

Blue spot light
The blue spot light projects a visible beam on the ground, indicating the forklift’s direction of travel. This enhances safety by alerting nearby workers to the forklift’s movements, especially in busy environments.

Alarm Lamp
With an alarm lamp integrated into the design, this device offers a highly visible warning solution for forklifts and industrial vehicles. The bright, flashing light enhances safety by alerting personnel to the presence of the vehicle, especially in busy or low-visibility environments. Available in various colors, including amber, red, and blue, the alarm lamp can be customized to meet different safety requirements and regulations. Durable and weather-resistant, it ensures reliable performance in diverse working conditions, helping to prevent accidents and improve overall workplace safety.

Reverse Alarm
The reverse alarm adds an important safety feature by emitting a loud sound when the stacker is moving in reverse. This alerts nearby personnel of the stacker’s movement, reducing the risk of collisions or accidents. The reverse alarm is especially useful in crowded environments, helping to keep both operators and others in the workspace aware of the stacker’s actions.

Mirror
Equipped with a mirror, this option improves rear visibility for the operator, enhancing safety when maneuvering in tight or crowded spaces.

Cold store protection
Designed for extreme cold storage environments, this electric pallet truck is equipped with specialized features such as cold store oil, anti-slip platforms, and heated batteries. Built to operate seamlessly in low-temperature conditions, it ensures reliable performance and durability in harsh environments. With enhanced insulation and robust components, this version guarantees efficiency and safety in demanding cold storage applications.

Fire Extinguisher
This quick-release, vehicle-mounted fire extinguisher is specifically designed for forklifts, featuring OSHA-compliant construction for industrial safety. Its easy-access mounting and instant activation ensure rapid response to engine, battery or electrical fires. The compact yet powerful system provides reliable protection for operators and equipment in critical situations. Vibration-resistant brackets keep the unit securely in place during all forklift operations.
