⚙️ Engine Specifications

Engine Types:

Mitsubishi industrial engines (specific models vary by forklift capacity and fuel type). Common diesel engines might include variations of S4S, S4Q2. Common gasoline/LPG engines might include variations of 4G5, 4G6, or other industrial variants.

Cylinder Configuration:

Typically 3 or 4 cylinder inline configurations for the industrial engines used.

Power Output:

Varies by model and engine, typically ranging from approximately 40 HP to 70 HP for the listed capacities (e.g., FD10-35A, FG10-35A).

Torque Output:

Varies by model and engine, optimized for lifting and low-speed operation.

Diesel Fuel System:

Direct injection, common rail (on newer models), fuel injection pump, injectors, fuel filters.

Lpg Gasoline Fuel System:

Carbureted or fuel injected (depending on specific engine variant), LPG vapor or liquid fuel system, fuel filters, solenoids.

Type:

Water-cooled, typically with a radiator, fan, water pump, and thermostat.

🔧 Transmission

Type:

Automatic transmission (torque converter type) is common for this series of forklifts. Some may have manual options for specific applications or older models.

Type:

Manual transmission may be available on some specific configurations.

Hydraulic Control:

Operates via a hydraulic system for gear engagement and torque conversion.

Fluid Type:

Typically requires a specific automatic transmission fluid (ATF) or hydraulic fluid. Manuals will specify exact types (e.g., Dexron III equivalent or industrial hydraulic fluids).

📐 Dimensions

Mast Configurations:

Various mast types including standard lift, duplex, and triplex masts with different lift heights and free lift capabilities.

Operating Weight:

Ranges significantly based on model capacity (e.g., FD10/FG10 approx. 2000-2500 kg, FD35A/FG35A approx. 4500-5000 kg).

Load Capacity:

From 1000 kg (FD10/FG10) up to 3500 kg (FD35A/FG35A) at a specified load center (e.g., 500mm).

🛡️ Safety Features

Industrial Standards:

Designed to meet relevant industrial safety standards (e.g., ANSI/ITSDF B56.1 in the US, EN standards in Europe).
