The TW25 forklift is a 51 hp model with 4×4 in-wheel motor technology that reaches 24 km/h and lifts loads of 2,500 kg at six metres high.
It is a vehicle of compact dimensions and short turning radius. Thanks to this, it develops with agility inside buildings under construction, garages, warehouses, etc. It also does so in greenhouses and farms. Its small size makes it possible to work in any environment and the power that can take care of the most demanding tasks.
The relationship between height and width added to the balance of weights and the anti-skid block that coordinates the effort of the four wheel motors, giving it admirable stability on rough terrain. If we add to this the 345 mm of free height to the ground, we understand the magnificent performance when overcoming curbs, sinkholes, slopes, mulls, icy surfaces, etc.
The use of in-wheel motors is a distinctive feature of Agrimac trucks. The TW25 does not have differential bridges but hydraulic motors on the axle of each wheel. These engines are coordinated by an anti-skid block that distributes the effort of each wheel guaranteeing grip and improving the efficiency of the transmission of energy from the engine to the ground.
The commitment to this technology determines a multitude of aspects of the vehicle. For example, in-wheel motors weigh less than differential bridges, have fewer components and their mechanics are simpler. This reduces maintenance cost and fuel consumption. In addition, the fact that the motorisation weighs and occupies much less allows to gain free height to the ground and improve the distribution of weights. Driving is also affected. In-wheel motors allow a faster and more accurate response to driver demand. The consequence is greater safety and a more pleasant feeling behind the wheel.
This model is the emblem of a new generation of Agrimac trucks. The TW25 Stage V forklift is the evolution of the TW25 Stage IIIA model. However, it represents a technological leap that places it in a different generation. It is a development from scratch that responds to two motivations: on the one hand, compliance with the European gas emission regulations 2016/1628 and on the other, the achievement of a technologically cutting-edge model. These two objectives materialise in all the components and designs of the machine: motorisation, hydraulics, electronics, safety, aesthetics, etc.
Thus, Agrimac’s engineering team has opted for the Kohler KDI 1903 TCR diesel engine that has burst into the European stage five emissions market with the best power-expenditure ratio while more than complies gas emission requirements. This engine provides a torque of 170 Nm which is 15% more than other equivalent engines on the market. It is designed to work continuously generating this great power with minimal fuel consumption. In this regard of savings it should also be emphasised that it has a transmission belt that lasts three times as long as standard belts.
Like the rest of Agrimac’s medium-sized trucks, the transmission is hydrostatic with in-wheel motors. In the case of the TW25, four in-wheel motors, that is, the best possible 4×4 traction configuration. The pump motor is Poclain. Agrimacs trusted partner with which we have worked for years with great technological and commercial success. In this model, compared to the previous one, engineers have increased the flow of both the work pump and the displacement pump while maintaining pressure. This gives even more performance to the vehicle. With this same objective, they have also stabilised the working temperature of the oil at 50 degrees, that is ideal for this type of system. This is achieved thanks to two electric fans installed in the front of the vehicle that are independent of the radiator that dissipates heat through the opening in the counterweight of the truck. Engine cooling is greatly favoured in this model by the half-height intake mushroom that absorbs air without impurities.
This model has installed four Minimex test points, accessible from the outside of the vehicle. They are hydraulic sockets that connected to a pressure gauge serve to measure the pressure of different parts of the hydraulic system and check that they are working on the appropriate values.
A key aspect of any vehicle is the driving experience. In a 4×4 truck with in-wheel engines can be summarised in ease, agility and safety. If we talked about animal labour power as in the last century, it should be said that this specimen is the most powerful and best tamed. Manoeuvring with this forklift is so simple and intuitive that any novice feels expert behind the wheel. To further emphasise this feeling, both the engine and the cabin are mounted on four shock absorbers. Each one with a double anti-vibration system. Thanks to this, engine noise and vibrations are reduced while isolating the cabin from both. As a result, a smooth and precise driving is obtained.
Following the precision, the TW25 has a slow approach system for loading and unloading that is incorporated into the brake pedal.
The brake priority valve that allows braking force to be gained with less pressure on the pedal and the negative brake can be considered part of the safety chapter. Here it is worth highlighting some functions such as the emergency braking system. It is an oil accumulator that allows up to ten emergency braking by pressing the running brake with the engine off. The TW25 still has another braking system: it is an emergency pushbutton on the dashboard of the vehicle that when pressed turns off the systems and activates the negative brake.
As if that were not enough, the truck is configured to stop the gear and activate the brake if the pressure sensor installed in the seat indicates that the driver is not behind the wheel. The vehicle control unit can also be configured to prevent movement if the driver does not have a seat belt fastened.
These types of safety devices are controlled through the forklift interface. It consists of a screen under the steering wheel and buttons on the control knobs. This screen shows the information you receive from the engine switchboard, the pump control unit and other sensors distributed throughout the machine. From here, data is obtained on engine revolutions, fuel tank, temperature, working hours, particle filter saturation, etc. All possible interactions and configurations that can be realised in this interface are described in the user manual.
The main thing in sight remains for the end. With the TW25 Agrimac debuts a more modern aesthetic. A design characterised by rounded lines and aerodynamic appearance in which more importance is given to the driver. The cabin is wider, better insulated and has a better view of both the load and the environment. In turn, the seat adapts to all driver sizes as well as the steering wheel. It also has excellent lighting with large driving lights and work according to a well-equipped vehicle in the electronic aspect. In short, the aesthetic accompanies a whole series of features to make this vehicle the operator’s office. A comfortable job place to make the feeling of long workdays shorter.
