⚙️ Engine Specifications

Primary Engine

Engine Type:

Internal Combustion (likely a 4-cylinder industrial engine).

Fuel Type:

Propane (LPG) is common for 'FG' models, but gasoline variants also exist. Specific HO variant needs confirmation.

Displacement:

Varies by specific engine fitted, but typically in the 2.0L - 2.5L range for this class.

Performance

Horsepower:

Typical range for this class is 50-70 HP.

Torque:

Focus on low-end torque for lifting applications.

Fuel System

Injection Type:

Likely Fuel Injection (EFI) for modern units.

Cooling System:

Water-cooled, typically with a radiator and fan.

🔧 Transmission

Standard

Transmission Type:

Likely a 1-speed or 2-speed hydrostatic or torque converter automatic transmission.

Optional

Optional Transmission:

Less common for industrial forklifts to have widespread transmission options within a specific model code, but variations may exist.

Features

Drive Modes:

Forward/Reverse selection, potentially with inching control.

Transmission Fluid:

Specific ATF or hydraulic fluid type will be detailed in the manual. Capacity also specified.

📐 Dimensions

Exterior

Overall Length:

Varies based on mast configuration and presence of attachments. Approx. 2.5-3.5 meters without forks.

Overall Width:

Typically around 1.1-1.3 meters.

Mast Height:

Highly variable based on duplex, triplex, and free-lift configurations. Standard masts often 3-4 meters extended, retracted height also crucial.

Weights

Operating Weight:

Typically in the 3000-4000 kg range, depending on configuration and counterweight.

Load Center:

Standard is 500mm (24 inches) load center for 2000kg capacity.

Cargo

Fork Length:

Standard forks are often 1070mm (42 inches) or 1220mm (48 inches).

🛡️ Safety Features

Ratings

Design Standards:

Manufactured to meet relevant ANSI/ITSDF, ISO, or other regional safety standards for industrial trucks.

Active Features

Operator Presence System:

Commonly includes a seat switch that disables drive and hydraulic functions when the operator is not seated.

Parking Brake:

Mechanical or electronic parking brake for secure stationary operation.

Passive Features

Overhead Guard:

Standard feature to protect the operator from falling objects.

Seat Belt:

Standard safety restraint for the operator.

Load Backrest:

Protects the operator from shifting loads.

💡 Technology Features

Infotainment

N A Industrial:

N/A (Industrial equipment focused on functionality, not typically equipped with infotainment).

Driver Assistance

Operator Feedback:

Dash-mounted indicators for engine status (oil pressure, temperature, battery), hour meter, and sometimes diagnostic trouble codes.

Connectivity

Telematics Potential:

Modern forklifts may have optional telematics for fleet management, hour tracking, and fault reporting, though not guaranteed on all FG20K HO units.

🔧 Maintenance

Service Intervals

Engine Oil Change:

Typically every 250-500 operating hours, depending on operating conditions and oil type.

Transmission Fluid Change:

Usually every 1000-2000 operating hours, or as specified by the manufacturer.

Hydraulic Filter Change:

Often coincides with hydraulic fluid changes, or more frequently if contamination is suspected.

Air Filter Replacement:

Regular inspection and replacement, especially in dusty environments (e.g., every 250 hours or as needed).

Lubrication:

Daily or weekly checks and lubrication of mast channels, linkages, and steering components.

Fluid Specifications

Engine Oil:

Specific viscosity grade (e.g., 10W-30, 15W-40) and API classification will be detailed. Capacity around 4-5 liters.

Transmission Fluid:

Requires specific Automatic Transmission Fluid (ATF) or a dedicated hydraulic fluid. Capacity around 8-12 liters.

Coolant:

Ethylene Glycol based antifreeze/coolant mixture. Capacity around 8-10 liters.

Known Issues

Common Wear Items:

Mast rollers, lift chains, fork wear, brake pads/shoes, tires, seat upholstery.

Hydraulic Leaks:

Potential for leaks in hoses, seals, or cylinders due to constant use and pressure.
