Lithium Battery Forklift

The 3.5-ton electric forklift is a commonly used handling equipment in medium and large-scale warehousing, logistics, and industrial scenarios. With its characteristics of high efficiency, environmental friendliness, and low maintenance, it is widely applied in warehouses, ports, factories, supermarkets, and other settings.

I. Basic Parameters

II. Core Technology and Power System

1. Power Configuration

Motor Type: Adopts brushless AC motor (high efficiency and energy saving, fast torque response). Some high-end models support four-wheel drive (climbing capacity ≥ 15°).

Battery Technology: Lithium battery (maintenance-free, long service life, fast charging, supporting 80% charge in 3 hours with fast charging).

Charging System: Standard-equipped intelligent charger, supporting constant current/constant voltage charging mode to extend battery life; some models support battery swapping mode (suitable for high-frequency operation scenarios).

2. Drive and Control

Drive Mode: Rear-wheel drive (mainstream) or four-wheel drive (for complex ground scenarios), with standard anti-slip tires (adapting to wet, slippery, and uneven ground).

Steering System: Hydraulic power steering, featuring light operation and small turning radius.

Braking System: Dual protection of electromagnetic braking + mechanical brake. Manual braking is available in emergency situations to ensure parking safety.

Operation Interface: Equipped with an LED display, which shows key data in real time, such as battery level, fault codes, and working hours.

III. Structural Design and Durability

1. Frame and Mast

Frame: Welded with high-strength steel plates, and treated with integral shot blasting + plastic spraying process (corrosion-resistant, impact-resistant), with a service life of ≥ 10 years.

Mast: Double-stage mast (or triple-stage, optional based on lifting height), made of C-section steel or H-section steel. The rollers adopt a composite design of bearing steel + polyurethane (low noise, wear-resistant), ensuring stable lifting without jitter.

2. Forks and Accessories

Standard Forks: Length ranges from 1.2m to 1.5m (extended forks optional), made through forging steel + heat treatment process (rated load ≥ 4.5 tons), supporting side shift (±150mm) and tilt (±6°) functions.

IV. Safety and Protection Configuration

1. Basic Safety

Lighting and Warning: Standard-equipped LED headlights (IP67 waterproof rating), turn signals, brake lights, and warning horns.

Protective Structure: Fully enclosed overhead guard (withstanding impact ≥ 100kg) and high-strength metal load backrest to prevent goods from slipping.

2. Intelligent Safety

Roll-Over Protection System (ROPS) (Optional): When the vehicle tilts more than 12°, the system automatically restricts lifting and gives an alarm.

Collision Avoidance Warning (Optional): Monitors obstacles ahead through ultrasonic radar or cameras. When the distance is ≤ 1.5m, it issues an audio-visual alarm and decelerates.

Overload Protection: Monitors the load weight in real time. When overloaded, it restricts lifting and gives an alarm.

V. Auxiliary Functions

Some models support functions such as automatic weighing (accuracy ±0.5%), automatic fork leveling (adapting to uneven ground), and IC card key (contactless unlocking), which improve operation efficiency.

VI. Application Scenarios

With its load capacity and flexibility, the 3.5-ton electric forklift is mainly applicable to:

Warehousing and Logistics: High-level rack stacking (above 4.5m) and full-pallet handling in third-party logistics centers and e-commerce warehouses.

Manufacturing Industry: Short-distance transportation of raw materials, semi-finished products, and finished products in factory workshops (e.g., automobile, electronics, and machinery industries).

Cold Chain and Special Environments: Low-temperature batteries (applicable for -20℃ ~ 40℃) can be optional, which are used for goods handling in cold storage (customized design required).

Commercial Retail: Goods loading/unloading and warehouse organization in large supermarkets and wholesale markets.

VII. Maintenance and Service

Maintenance Cycle: Daily inspection (daily) + primary maintenance (every 500 hours) + secondary maintenance (every 2000 hours). The lithium battery version does not require electrolyte replacement, and its maintenance cost is 40% lower than that of the lead-acid battery version.
