HAMAC dual fuel forklifts are available from 1.5 tons to 5 tons. The 1.5T, 1.8T and 2T LPG/gasoline forklifts are suitable for pallet handling in warehouses, workshops, small factories, loading areas and distribution facilities. The 2.5T, 3T and 3.5T dual fuel forklifts are the main models for truck loading and unloading, factory logistics, beverage handling, packaging plants, rental fleets and general industrial material handling.

For heavier palletized cargo, HAMAC can provide 4T and 5T dual fuel forklift solutions for building materials, timber, large cartons, machinery components, metal products and industrial goods. The LPG system allows rapid cylinder replacement where LPG is readily available, while the gasoline system offers an alternative fuel source when required. Before ordering, HAMAC will confirm the local fuel specification, engine configuration, emission requirement, tire type, mast height and residual capacity for the customer’s application.

Product Advantages

01 Powerful Engine Performance

HAMAC internal combustion forklifts are available with diesel, LPG, gasoline and dual-fuel power options to match different operating requirements. Diesel forklifts provide strong torque for heavy loads and outdoor work, while LPG and gasoline forklifts offer flexible performance for factory, loading dock and mixed indoor-outdoor applications with suitable ventilation. IC forklift power systems are designed to deliver stable travel performance, responsive lifting and dependable operation during continuous material handling tasks.

02 Fast Refueling for Continuous Work

Internal combustion forklifts can be refueled quickly, helping customers reduce downtime during long shifts and high-frequency handling operations. Diesel tanks can be refilled efficiently, while LPG cylinders can be replaced quickly when fuel is available on site. This makes diesel, LPG and dual-fuel forklifts a practical choice for rental fleets, logistics yards, busy loading areas and operations that cannot wait for battery charging.

03 Built for Outdoor and Heavy-Duty Applications

With durable frames, powerful engines, high ground clearance and robust drive systems, HAMAC internal combustion forklifts are suitable for industrial yards, construction material storage, timber yards, factories, ports and outdoor logistics areas. They can handle demanding work involving building materials, machinery parts, steel products, timber, palletized cargo and other heavy industrial loads.

04 Pneumatic Tire Options for Uneven Ground

HAMAC diesel and LPG forklifts can be equipped with pneumatic tires for better traction and stability on paved yards, loading areas and uneven outdoor surfaces. This configuration is especially suitable for construction sites, lumber yards, agricultural facilities, ports and industrial areas where a standard warehouse electric forklift may not be the best choice. Pneumatic-tire IC forklifts are widely used where ground clearance, durability and outdoor mobility are important.

05 Configurable Fuel, Mast and Attachment Solutions

Customers can choose diesel, LPG, gasoline or dual-fuel forklift configurations based on fuel availability, operating hours, emissions requirements and working environment. HAMAC can also provide duplex or triplex masts, full free lift options, side shifters, fork positioners, fork extensions, cabins, air conditioners, warning lights and specialized attachments to match pallet sizes, rack heights and handling tasks. Industry IC models commonly offer diesel, LPG or dual-fuel versions within comparable 2.0–3.5T capacity classes.

06 Durable Design and Operator Comfort

HAMAC internal combustion forklifts are designed for long operating hours with an ergonomic operator area, clear forward visibility, practical controls and service-friendly component access. Heavy-duty cooling, reliable drivetrain components and reinforced chassis configurations help support stable operation in hot, dusty and demanding work environments. Contemporary diesel/LPG forklift designs commonly combine enhanced cooling, wet-disc brake axles, ergonomic cabins and durable powertrain components to improve uptime and serviceability.

Common FAQs

What is a dual fuel forklift? −

A dual fuel forklift is an internal combustion counterbalance forklift designed to operate with both LPG and gasoline. This system allows the operator or fleet owner to use the fuel source that is more available or practical at the site. HAMAC dual fuel forklifts are suitable for factory logistics, truck loading, warehouse loading areas, rental fleets, and mixed indoor-outdoor material handling with sufficient ventilation.

What is the difference between an LPG forklift and a dual fuel forklift? +

An LPG forklift is designed to operate on liquefied petroleum gas only, while a dual fuel forklift can use both LPG and gasoline. A HAMAC LPG / gasoline dual fuel forklift provides additional flexibility for customers whose LPG cylinder supply, gasoline availability, or fuel costs may change between locations or projects.

What capacities are available for HAMAC dual fuel forklifts? +

HAMAC dual fuel forklifts are available from 1.5 tons to 5 tons. The main range includes 1.5T, 1.8T, 2T, 2.5T, 3T, 3.5T, 4T, and 5T dual fuel forklift models. The 2.5 ton dual fuel forklift, 3 ton dual fuel forklift, and 3.5 ton LPG/gasoline forklift are common choices for factory logistics, truck loading, and general industrial pallet handling.

Can a dual fuel forklift be used indoors? +

A dual fuel forklift can be used in an indoor or semi-indoor work area only when ventilation is sufficient and local safety, emission, and workplace regulations are met. LPG generally produces lower emissions than gasoline, but neither fuel option makes the forklift emission-free. For enclosed warehouses, food facilities, pharmaceutical operations, or places requiring zero exhaust emissions, HAMAC recommends an electric forklift.

How does an LPG / gasoline dual fuel forklift change fuel? +

The exact fuel switching method depends on the installed engine and dual fuel system. In general, the forklift is configured to operate with LPG from the mounted cylinder or gasoline from its fuel system. The switching procedure, safe shutdown steps, and maintenance requirements must follow the supplier’s operating manual and be carried out by trained personnel.

What are the benefits of a dual fuel forklift? +

The main benefit of a dual fuel forklift is operating flexibility. Customers can use LPG when quick cylinder replacement and cleaner-burning fuel are preferred, or gasoline when it is more readily available at the work site. This can help reduce interruptions caused by local fuel supply changes and is useful for rental fleets, dealers, factories, and projects that operate in different locations.

What tire options are available for dual fuel forklifts? +

HAMAC dual fuel forklifts can be supplied with pneumatic tires, solid tires, or cushion tires. Pneumatic tires are suitable for outdoor yards and mixed surfaces, cushion tires are suitable for smooth and level indoor factory floors, and solid tires are useful where puncture resistance is important. The correct tire option should be selected according to the actual working surface.

What lift heights are available for dual fuel forklifts? +

HAMAC dual fuel forklifts can be equipped with duplex or triplex mast configurations. Standard lift height is typically 3000 mm, while optional lift heights can range from 3000 mm to 6000 mm depending on the forklift capacity, mast type, tire selection, attachment weight, and residual capacity requirement. Full free lift mast options can be selected for specific warehouse and container loading applications.

Can attachments be installed on a dual fuel forklift? +

Yes. HAMAC dual fuel forklifts can be equipped with side shifters, fork positioners, fork extensions, long forks, carton clamps, bale clamps, paper roll clamps, drum handlers, and other material handling attachments. Attachment weight and load center must be reviewed because they affect the forklift’s residual lifting capacity and stability.

What information is needed to select the right dual fuel forklift? +

Please provide the required capacity, load center, maximum lift height, pallet dimensions, indoor or outdoor working environment, ventilation condition, preferred tire type, local LPG and gasoline availability, daily operating hours, attachment requirement, quantity, and destination country. HAMAC can recommend a suitable LPG / gasoline dual fuel forklift configuration with the correct engine, mast, tires, cabin, and attachments.
