Product Overview: 4 Ton Internal Combustion Forklift
As a large-tonnage heavy-duty internal combustion forklift, it is equipped with diesel and LPG (liquefied petroleum gas) dual power options. It delivers vigorous power and high torque with excellent endurance, and is completely free from the restrictions of charging facilities. Adopting a full-size reinforced heavy-duty frame, the vehicle features solid structure, stable driving, precise and flexible steering, as well as outstanding trafficability.
With high-level overall protection, it can adapt to various harsh outdoor and semi-indoor working conditions. Thanks to its excellent heavy-load performance, exquisite manufacturing craftsmanship and remarkable cost performance, it has become the core working equipment for large heavy industrial enterprises, port yards, comprehensive logistics hubs, steel markets and large building material markets to stack, transport, load and unload large-tonnage goods. Whether you are a warehouse manager, factory director, logistics contractor or industrial park operator, our 4 ton internal combustion forklift can provide you with a powerful, all-weather, stable and reliable large-tonnage material handling solution.

This large heavy-duty forklift is professionally developed for demanding super heavy-load working scenarios. Every frame component, power unit and hydraulic assembly has been fully reinforced and upgraded. Different from medium-tonnage models, its extra-thick integrated die-cast frame greatly enhances impact resistance, torsion resistance and fatigue resistance, so it will not deform even after years of continuous full-load operation. The mature high-power internal combustion system provides sustained and abundant power, ensuring no power loss during long-distance transportation and frequent loading & unloading. Free from charging limitations, it can start work right after refueling, which is extremely suitable for remote yards and port areas without stable power supply. With a reasonable body design, it balances extreme load capacity and flexible passing performance, and can operate efficiently in large warehouse aisles and complex outdoor sites. Low failure rate and simple maintenance make it a trustworthy heavy-duty workhorse for all kinds of large-scale enterprises.

Product Features
Dual Power Options: Both diesel and LPG power are available. Diesel power generates large torque and strong explosive force with convenient refueling, which is the first choice for high-intensity large-tonnage outdoor work. LPG power runs with low vibration and noise and produces clean exhaust gas, making it ideal for semi-indoor areas and factory warehouses with ordinary ventilation.
Powerful Performance: Adopting a mature high-power internal combustion assembly, it provides continuous and stable power. There is no power attenuation during starting, climbing, full-load driving and long-distance transportation, enabling it to handle high-intensity continuous work easily.
Long Endurance: Fitted with a large-capacity sealed fuel tank. One full refueling supports extra-long continuous operation and avoids frequent refueling, greatly improving overall work progress and efficiency.
Easy Operation: Designed with ergonomic driving layout. The control levers and steering wheel are reasonably arranged with light and smooth steering. New operators can get skilled after simple training.
High Safety: Standard equipped with heavy-duty overload protection, reinforced anti-tilting device, emergency stop button and other safety components. Optimized specially for large-tonnage work, it fully protects the safety of operators and goods.
Strong Environmental Adaptability: The whole machine adopts complete dust-proof, rain-proof, anti-freezing and anti-sediment sealing design. It can work stably all day long in high temperature, low temperature, rainy, snowy, dusty, gravel and bumpy road conditions, suitable for both indoor and outdoor use.
Durable & Easy Maintenance: Core power and hydraulic parts are high-quality original parts with exquisite workmanship and low failure rate. Spare parts are widely available. Daily inspection, oil replacement and filter cleaning are simple procedures, which greatly reduce later maintenance costs.
Fully Customizable: Lifting height, mast types, fork sizes and wheel sets can be adjusted as required. A variety of professional attachments including heavy-duty side shifters, extended forks, heavy-duty clamps and fork rods are optional. It can be flexibly adapted to heavy-load working conditions in heavy industry, ports, logistics and building material industries.
