The Q-Series concept perfectly realises NOBLELIFT's core motto - „Why choose between price and quality when you can have both“ - the Q-Series is specifically designed to meet today's challenges of being efficient, reliable and affordable, making it the perfect choice for both light duty and heavy duty applications.
NOBLELIFT already comes with a lot of standard equipment as standard:
| ILLUSTRATION | DESCRIPTION |
 |
As standard, the loader is equipped with the following LED lights: headlights, front cornering lights, rear combination lights, warning lights. The lighting is bright and uses low energy and allows free operation at night. A reversing work lamp can be ordered as an option |
 |
Compared to other Noblelift N-Series 4-wheel electric forklifts, this model is lower and more manoeuvrable, which is an advantage when working in confined or narrow spaces. |
 |
Just before the forks finish descending, the descent automatically slows down, protecting both the load from shocks and the floor surface from damage. |
 |
The front axle (also the driving and braking axle) has a 2-stage horizontally mounted reduction gear. The two-stage gearbox has a high transmission coefficient, so that the engine can run at higher speeds to get off the ground and then needs less energy to overcome inertia. On the other hand, the high gear ratio of the gearbox allows the traveling motor to run at higher speeds, whereas in the case of AC motors it is the case that the higher the speed at which the motor can run, the less energy it uses. |
 |
The rear axle and at the same time the steering axle have a vibration-absorbing design (mounted in the body on large rubber cushions), i.e. the use of curved flexible joints, which provides additional protection for the whole loader and extends the service life of the loader. |
 |
The forklift's driving and braking controls are also adapted from the automotive industry: in real terms, the controls are the same as those of a car with an automatic gearbox. The speed control is smooth and proportional, which undoubtedly adds to the comfort during operation. |
  |
Hydraulic controls can be either mechanical levers or mini-levers in the armrest. If armrest mini-lever control is chosen, then the hydraulic components are from Bosch Rexroth, while the mini-levers and the fully shock-absorbing seat are from GRAMMER (Germany) |
 |
The Q-Series uses the standard CURTIS multi-function display. It allows you to select the required operating mode (E, S, H or slow (turtle)), displays the battery charge level, travel speed, moto hours, error messages, allows you to change other loader parameters, etc., etc. |
 |
In the case of fully electric brakes, the loader is equipped with an emergency brake activation button that simply disconnects the power supply and the brakes automatically lock. |
The driver's compartment is designed in line with best ergonomic practices: spacious cab, excellent visibility both directly through the boom and through its sides, right-hand hydraulic control (with both mechanical and mini-levers in the armrest), comfortable fully adjustable and shock-absorbing seat, low-lying boarding step, quiet operation, low vibration, USB sockets, a place for a drink and a binder holder, a sports steering wheel with an additional steering wheel („bulb“), grab handles for entry or reverse (with an additional acoustic signal), and a full set of lights at all times - all of which will keep you working comfortably and safely.
OPTIMISED POWER PLANT BASED ON CURTIS TECHNOLOGY
Another unique advantage is the use of advanced electric actuators („controllers“) that control both the travel and lift motors. The actuators used are market reference, reliable and of high quality (e.g. Curtis, etc.). The electric drives fully control the entire forklift truck - a CAN - BUS bus controller is installed, so that all the electrical components are connected directly to the drive controller, giving the forklift truck optimum control and, at the same time, extremely good and detailed diagnostics. The drives themselves are mounted in the upper inner part of the housing for better ventilation and easy access when needed.
If a lithium iron phosphate battery is used in a forklift truck, its diagnostics shall be carried out via the gear 
widgets. And since Noblelift also uses the CURTIS display, which allows efficient settings changes, the lithium battery settings (such as operating temperature, permissible depth of discharge, etc.) can be changed as needed.) via the same display, or to monitor battery parameters (such as cell balance, number of charge/discharge cycles, history of current magnitudes, energy consumption, temperature, charge/discharge parameters, voltage of each cell, faults and alarms, automatic shutdown time settings, etc.). In other words, the Q-Series is fully optimised and does not have any intermediate circuits or third-party adaptors in its electrical circuit and signal transmission - this is particularly important for lithium batteries, as very often lithium batteries have separate diagnostics, which makes it very difficult to maintain or repair the forklift. All this is not available on the Q-Series.
On the other hand, most Noblelift Q-Series lithium batteries already come with a battery passport, which can be accessed by scanning the QR code on the battery. With the same QR code, the electronic SIM card (which is installed in most Noblelift lithium batteries) can be activated and Noblelfit then gets remote access to the lithium battery and can perform factory diagnostics and change or update the battery settings if necessary.
The use of verified and certified components helps to ensure compliance with EU safety standards with all available supporting documentation, as required by EU legislation.
If a lithium iron phosphate battery is chosen, it is particularly important for customers to know the basic rules for correct operation:
- Operating temperature from -200C to +500C. The protections start to activate at -150C and +350 C
- Theoretical storage temperature: -300C to +600C. In practice, we recommend that you do not keep a battery discharged below 70% at a negative temperature (i.e. not working).
- Permissible ambient temperature during charging +00 C, optimum +20-250C
- Recommended battery discharge level: 100% to 30%, allowable discharge up to 15% (discharging below this level triggers the protection)
- Optimal battery operating status is above 50%. Lithium batteries „like“ to operate in a high state of charge. Then its battery life is 2 - 3 times longer
- Partial charges: it is recommended to use them only when necessary and to always try to charge the battery above 50% before stopping the charge. Another way to proceed when it is seen that the battery will not be sufficient for all the work is to build a full or partial charge and not wait until the battery reaches 50% or 30%, but when there is a window of opportunity. For the specific batteries used in Noblelift it is „healthy“ to be better to be fully and continuously charged more often, but not more often.
- Standard charging. It is recommended to always fully charge the battery whenever possible, and to leave the charger on at least once every 2 weeks for a few hours after a full charge to allow the battery to fully balance.
AC TRACTION MOTORS THAT DO NOT REQUIRE SPECIALISED MAINTENANCE
The Q-Series has powerful and maintenance-free AC motors. Compared to traditional DC motors, Noblelift AC motors do not require the replacement of carbon brushes. They are equipped with speed and temperature sensors, which greatly improves the reliability of AC motors.
QUIET, LOW VIBRATION DESIGN
The hydraulic system uses a silent plunger pump and includes full hydraulic power steering. The system is quiet and easy to operate. The rear axle and at the same time the steering axle have a vibration-absorbing design (mounted in the body on large rubber cushions), i.e. the use of curved flexible joints, thus providing additional protection for the whole loader and extending the service life of the loader.
REPLACING THE BATTERY THROUGH THE SIDE
If the Q-Series is ordered with a standard lead-acid battery, the ability to quickly change the battery sideways using a simple hydraulic pallet truck or simply another forklift truck comes as standard.
SAFER AND SIMPLER ELECTROMAGNETIC BRAKE
The Q-Series can be equipped with hydraulic or fully electric brakes. Electric brakes use the principle of automotive brakes plus an additional parking (emergency) electromagnetic brake that blocks the travel motor directly. Of course, braking with electric brakes is more fun and requires less effort. However, hydraulic brakes have their own advantages.
LOW CENTRE OF GRAVITY
The front axle (also the drive and braking axle) has a 2-stage horizontally mounted gearbox, The 2-stage gearbox has a high transmission coefficient so that the engine can run at higher speeds to get off the ground, requiring less energy to overcome inertia. On the other hand, the high gear ratio of the gearbox allows the travel motor to run at higher speeds, whereas in the case of AC motors it is the case that the higher the speed at which the motor can run, the less energy it uses. The low centre of gravity is also contributed to by the battery mounted on the bottom of the frame, giving the loader stability.
RELIABLE LIFTING MECHANISM
Noblelift uses a classic jib design - a wide profile construction that accommodates large bearings. The boom sections have internal lateral stabilisers which have 2 functions: to improve the lifting performance at high altitudes and to reduce the natural wear on the boom. The lateral fork pushers and/or positioners are mainly used by CASCADE, a manufacturer that is very popular in this field and has earned a reputation as a reliable manufacturer.
