Condition: new, functionality: fully functional, Year of construction: 2026, Internal combustion forklift truck with a 2,500 kg load capacity Design and technology The forklift’s construction is made of high-strength materials, resistant to intensive use and outdoor conditions. The reinforced frame and high-rigidity mast ensure stability during lifting and transport operations. The Nissan K25 engine with an output of 50 HP is a well-established unit in the forklift industry, offering strong tractive force, durability, and excellent availability of spare parts. The Power Shift automatic transmission allows dynamic acceleration and smooth direction changes without loss of torque. In addition, the use of hydraulic brakes and support systems enhances operational safety and user comfort. Precision and operational efficiency The mast is equipped with a forward/backward tilt function (angle 6° / 12°), enabling safe and precise handling of loads in various working conditions. The side-shift function significantly reduces operating time by allowing fork position adjustments without repositioning the entire truck. Thanks to pneumatic tires with deep tread and high ground clearance, the forklift performs exceptionally well on uneven terrain, ramps, and loading yards. A travel speed of up to 19 km/h unloaded enables fast execution of handling and transport tasks over large areas. Standard equipment Nissan K25 internal combustion engine Power Shift automatic transmission Tilting mast Side-shift forks Complete work and warning lighting Reverse alarm, strobe light, turn signals 1,220 mm forks with manual spacing adjustment Choose a proven solution for internal logistics.

Condition: new, functionality: fully functional, Year of construction: 2026, Electric forklift truck with a 2,500 kg load capacity and 4,500 mm lifting height Design and technology The forklift is equipped with a modern electric drive that ensures quiet and emission-free operation. The power system is based on a high-performance 48V 490Ah battery, providing up to 10 hours of continuous operation. Compared to lithium-ion batteries, this battery offers up to 40% greater safety—it is resistant to mechanical damage, overheating, and does not emit harmful gases. A stable structure, precise hydraulic system, and a mast made of high-grade steel allow safe handling of loads at full capacity and maximum lift height. The forklift features a soft start system, power steering, and automatic speed reduction while turning, improving machine control and enhancing operator safety. Precision and operational efficiency The side-shift function allows fork position correction without the need to reposition the entire truck. Forward and backward mast tilt enables precise load placement and stable transport. A travel speed of up to 14 km/h and an optimized turning radius of 2172 mm make the forklift highly effective in narrow warehouse aisles. Applications This model is ideal for use in: high-bay warehouses and distribution centers, production plants with high material throughput, industries requiring clean, emission-free operation (food, pharmaceutical, chemical), outdoor loading areas – thanks to pneumatic tires and high ground clearance.

Condition: new, functionality: fully functional, Year of construction: 2026, Internal combustion forklift truck with a 3,500 kg lifting capacity Design and technology The forklift is equipped with reinforced load-bearing components, a durable frame, and a hydraulic system designed to operate under maximum load. The Nissan K25 engine is a proven power unit known for its high overload resistance and low fuel consumption. The Power Shift automatic transmission ensures smooth driving, increasing operator comfort and safety, especially during frequent direction changes. Pneumatic tires with increased diameter and deep tread perform exceptionally well on ramps, loading yards, and both paved and unpaved surfaces, effectively absorbing vibrations and reducing suspension wear. Precision and operational efficiency The side-shift mechanism allows horizontal fork movement, significantly reducing cycle time during storage and unloading operations. Manual fork spacing adjustment enables quick adaptation to different pallet sizes. Forward and backward mast tilt improves safety when handling heavy loads, facilitating precise placement and stabilizing the load during travel.
