Komatsu FG25T-17 is a 4 × 2 front-end forklift loader designed to carry out loading and unloading, transportation and other types of operations, primarily in warehouses (characterized by limited free space) ... Among its features are strong and reliable design, modern "filling" and excellent technical and operational characteristics

 By default, the Komatsu FG25T-17 is equipped with an open cab (devoid of doors and glazing), mounted on a suspension, which features a well-thought-out ergonomics of the operator's workplace. In addition, inside the car is capable of boasting a tilt-adjustable steering column and a comfortable seat with multi-directional adjustments, mechanical suspension and an inertial seat belt.

 The front-end loader has the following external dimensions: in length with standard forks, it is 3655 mm (to the front surface of the forks - 2585 mm), of which 1650 mm falls on the center distance, in width along the tires reaches 1150 mm, and in height does not exceed 2110 mm (on the upper mast guard). The ground clearance under the mast of the "Japanese" is 115 mm (in the center of the wheelbase - 160 mm), and its minimum turning radius is 2240 mm. The operating weight of the Komatsu FG25T-17 is 3590 kg, and its rated lifting capacity "rests" at 2500 kg. The total (structurally permitted) mass of the machine is 6090 kg, of which 5420 kg rests on the front axle, and the remaining 670 kg on the rear axle. The Komatsu FG25T-17 is equipped with a 2.1 liter (2065 cubic centimeters) naturally aspirated gasoline unit Nissan K21 with four in-line cylinders, overhead valves and carburetor fuel injection, generating 47 horsepower (34.6 kW) at 2450 rpm and 152 Nm of torque at 1600 rpm. It works in conjunction with a hydromechanical gearbox that sends all the potential to the rear wheels. When moving forward with a load, the car can accelerate up to 18.5 km / h, and without it - up to 19 km / h. For every hour of operation, it "drinks" about 5 liters of fuel, depending on the degree of load. Komatsu FG25T-17 is based on a frame architecture made of high-strength steel grades, on which the cab (on a mechanical suspension) and all the main units and assemblies are located. The front wheels of the loader are clad in pneumatic tires measuring 7.00-12-12PR, and the rear ones - 6.00-9-10PR. The machine is equipped with disc brakes immersed in oil, full hydrostatic power steering and a 58 liter fuel tank.
