INDUSTRIAL TRUCKS I FORKLIFT TEST The lifting and lowering speeds of the mast that we measured were perfectly acceptable. The mini levers (image 03) on the right armrest also ensure that the mast functions are simple and accurate to initiate. We were also satisfied with the amount of mast dampening that is also available in the lowest fork position. However, we did notice a weak point when lowering the loaded fork. This process exhibited a larger amount of play and torsion between the mast profiles and the entire mast construction, which is a lot more noticeable than we usually expect from Toyota forklifts. Features that increase comfort 04 A smaller distance to the floor would certainly increase the comfort when getting on and off As is often the case with forklifts in this load bearing capacity class, the manufacturer’s desire to integrate a battery that is as large as possible, minimize the length of the forklift, and provide generous access areas means that compromises have to be made. On the Traigo 80 this compromise has been made on the layout of the step (image 04). With a distance of 540 mm from the floor, we can only just refer to this as a comfortable means of access. This means that shorter drivers will have to exert a bit more effort when getting in to the forklift. However, as a virtual trade-off the step is deep enough that it increases safety when getting in and out of the forklift. The contrasting colors of the non-slip steel grates even make them easy to see when stepping off the forklift, thus enhancing safety. The generous amount of unobstructed space on the floor of the cabin ensures excellent driver comfort (image 05). Another contributing factor to the comfort of the driver are the rounded contours in the vicinity of the access area and battery compartment of the device. We also particularly appreciate that the lock for the battery cover is not located in the vicinity of the driver shaft thus preventing any inconvenient contact with the mechanics. The continuously adjustable steering column that is equipped with a memory function (image 06) is also advantageous. Using this function, the steering column can easily be returned to the right position after it has been moved forward to open the battery compartment cover. Due to the synchronization, the steering wheel must always be positioned in a clockwise direction of “twenty to the hour” to ensure safe operation when driving straight ahead. This is one of several functions that are part of the System of Active Stability (SAS) that Toyota has been using for several years now. Further features of this system, for example, include the steering axle stabilizer, automatic restriction of the tilt angle and tilt speed of the mast when the fork is elevated and automatic horizontal positioning of the fork when tilting. Our test forklift is also equipped with a display (image 07) that shows the approximate weight of the load being lifted and which enables the service technician to adjust the controls when driving around corners. In addition to the standard display of the operating hours and selected operat- 05 The generously proportioned footwell provides a lot of leg room and is free of obstacles Evaluation + Operating comfort + Robust design + Low energy consumption – Mast movement when lowering with a load – Storage space – Access height 20 f+h Intralogistics 1/2015

Performance profile We operated the Traigo 80 in the following three operating modes to measure the productivity and consumption: “H” (high performance), “P” (performance) and “S” (standard). It must be noted that “H” mode Information on the test forklift Dimensions and technical data Length to the fork face Overall width Mast height (retracted) Frame height Forks (LxWxD) Wheel base 2,429 mm 1,195 mm 2,235 mm 2,215 mm 1,150 × 100 × 40 mm 1,720 mm Ground clearance 90 mm Projection of front axle up to the fork face 420 mm Projection on rear side 289 mm Aisle width Maximum permissible load of the test forklift (according to load diagram) 3,958 mm 2,500 kg Centre of gravity of the load 500 mm Maximum lifting height Lifting height with maximum load of 2500 kg Free lift without load guards 4,730 mm 4,730 mm 1,576 mm Forward/backward tilt angle of lifting mast 4.5°/6° Speeds Lifting speed with 2/3 of the max. load/without a load (mode H) Lifting speed with 2/3 of the max. load/without a load (mode P) Lifting speed with 2/3 of the max. load/without a load (mode S) Lowering speed with 2/3 of the max. load/without a load (mode H) Lowering speed with 2/3 of the max. load/without a load (mode P) Lowering speed with 2/3 of the max. load/without a load (mode S) Forward/reversing driving speed with 2/3 of the max. load (mode H) Forward/reversing driving speed with 2/3 of the max. load (mode P) Forward/reversing driving speed with 2/3 of the max. load (mode S) Drive technology Drive motor Lifting motor Battery capacity of test forklift Stability 45.05/61.43 cm/s 39.42/58.40 cm/s 38.46/47.78 cm/s 54.37/40.78 cm/s 54.37/40.78 cm/s 54.37/40.78 cm/s 18.05/18.06 km/h 15.56/15.56 km/h 13.49/13.49 km/h 20 kW 25.50 kW 80 V, 775 Ah Net weight/percentage of rear axle 4,809 kg/49.78 % Weight at max. load/percentage of rear axle 7,309 kg/14.45 % Wheels Front/rear dimensions 23 × 9 – 10/18 × 7 – 8 Manufacturer/brand is a high performance program that is really only designed for long distances without a lot of curves. Operating mode “P” is the best in so far as handling the forklift is concerned. Mode “S” is eco mode and is suitable for longer periods of use. The claim by Toyota that the Traigo 80 is around 20 % more economical than its previous model, which we tested in 2003, was confirmed by the tests we completed. Marangoni (All of the details are based on research and measurements completed by the test team and can deviate from the manufacturer's specifications) In all of the settings, the forklift is more economical than the average of all the forklifts tested by us in this load bearing capacity class. Additionally, the device can always be used for a full working day. The forklift is 4.6 % less productive in mode “P” than in mode “H”, although this mode does save 16 % energy. In mode “S” the test forklift is 6 % less productive than in mode “P”, however it does save 13.3 % more energy in comparison to mode “P”. If the operator’s main focus is on the highest possible amount of operating hours and not on a high palette turnover, mode “S” will provide an energy saving of 28.9 % in comparison to mode “H”. If you combine the test as well as the measured and subjective results, it can be concluded that Toyota did its homework when developing and designing the Traigo 80.
