ERF25Q-ERF50Q
Rated Load: 2500-5000kg
Lifting Height: 4500-6000mm
TDER Sit-Down Omni-Directional Reach Truck is designed for medium- to heavy-duty warehouse and manufacturing operations. Combining reach capabilities with multi-directional maneuverability, it allows high-level stacking, lateral handling, and precise positioning in wide aisles or complex operational areas. Suitable for applications requiring high load capacity, operational efficiency, and operator comfort.
1. Omnidirectional driving system: Supports switching between forward and lateral driving modes, facilitating lateral handling and precise positioning under heavy load conditions.
2. Forward reach operation structure: Completes picking and placing through mast forward reach, reducing overall vehicle forward extension and enhancing adaptability to aisle width.
3. Full free three-stage mast: Separates lifting and free lift travel, providing a more stable view during high stacking, suitable for multi-tier rack operations.
4. AC drive architecture: Both travel and lifting use AC systems, delivering smooth power output, high operational consistency, and low maintenance requirements.
5. EPS electric steering system: Steering is light and precise, reducing operational intensity during low-speed heavy load and frequent direction changes.
6. Solid rubber wheel configuration: Strong load capacity, suitable for industrial floor conditions, improving overall vehicle stability and durability.
7. Integrated control handle: Centralized layout for travel, lifting, and function control with clear operational logic, reducing misoperation.
8. Adjustable fork spacing structure: Fork spacing adjustable for quick adaptation to different pallet specifications and cargo sizes.
9. Drive wheel display system: Real-time feedback on drive status, assisting the operator in judging driving and steering conditions.
10. Optional visualization and safety configurations: Supports optional cameras, color video displays, wipers, and card readers to enhance operational visibility, management compliance, and all-weather usability.
11. External intelligent charging solution: Paired with lead-acid batteries, offering intuitive charging management for centralized maintenance and daily management.
