It is generally used to control asynchronous motor cycles. Speed control of an asynchronous motor can be done in two different ways.
1- By changing the number of poles 2- By changing the motor feeding energy frequency
Unless double speed motor is used; Since it is impossible to change the number of poles of the motor in the installation, motor speed control can be done by changing the supply frequency. At this point, you need to include frequency inverters in your project. The motor speed with frequency inverters; It is possible to control the speed by keeping the motor at the desired point between the lowest and highest revolutions.
In frequency inverters; overload, over current, under and over-voltage, over-temperature, short circuit etc. there are protections. Frequency inverters; It corrects the mains voltages, absorbs, filters and cleans all voltage fluctuations, peaks, damaging electric currents that occur in the network with the help of capacitors and coils in hardware mechanisms.
Besides, as long as an emergency stop device is installed on the frequency inverter and appropriate equipment is prepared, your device can protect itself and your motor in any actionable situation that may occur in the system.
Today, many inverters are now manufactured with PLC functionality. Thanks to these smart applications of inverters, you can dance your asynchronous motor as you wish, and you can do many numerous applications such as PID method and MASTER-SLAVE with inverters.
Considering the sensitivity of the product carried by frequency inverters; With its soft start and soft stop feature, adjustable ramp times, follow-up of the instantaneous current-voltage-frequency curves of the motor, anti-sway, anti-grab and speed control according to the load if PLC hardware is added, instantaneous error codes, motor recognition features and with quality,It has become an indispensable part of Arnikon Engineering and Crane Systems.
As Arnikon Engineering and Crane Systems, we support frequency inverters to comply with new generation technology and quality standards; Considering the environmental conditions and occupational safety of the project site where the crane will be installed, we would like to state that it is the number one product of our electrical equipment group.
In line with our ongoing R&D studies in the smart crane sector, we adopted the PLC-Frequency Inverter-Motor and Frequency Inverter-Motor equipment as a company, and we used Frequency Inverter and Motor controls in all of our standard cranes; In our specially designed smart cranes; We make Frequency Inverter-Motor controls with PLC.

After three years of research and development, intelligent crane is already ready. This crane is the top advanced smart control system which can realize the various intelligent functions such as full automation of unmanned operation, smart safety monitoring, anti-swaying, speed extending, inching, automatic positioning, Smart load-floating, shock prevention, synchronization, anti-rope-slacking protection, etc.
Sway Control limits load swing by controlling the bridge and trolley acceleration and deceleration. Sway control allows faster load handling and more precise positioning. This feature also reduces the risk of damage to the load, crane and surrounding area. Active sway control designed to dampen also the existing load sway.
Snag prevention is designed to stop all crane movement if the hook, sling or load accidentally gets caught on something. This safety function reduces the risk of hazardous situations while moving loads and helps to prevent damage to the load, crane and surrounding area.
Adaptive speed range (ASR) and extended speed range (ESR) allows you to optimize the speed of your crane. An empty hook can be moved at over double the speed of a loaded hook, allowing the operator to choose the most efficient way to control the hoist. Variable hoisting speeds provide accuracy during slow-speed operation and shorter load cycle times during the faster operation.
Assisted load turning helps turn the load by keeping the ropes straight and eliminating side pull. this function makes one of the most challenging crane operation more simple and less risky. the benefits of this feature are faster load cycle times, longer crane lifetime and it simply makes the use of crane easier.
Hook centring is designed to eliminate side pull during lifting by positioning the bridge and trolley automatically directly over the load. This feature means less wear and tear on your crane’s components, faster load cycle times and ease of operation.
Hoisting synchronization monitors and controls the position difference of the hooks and synchronizes the movement of each hoist. This function gives more accuracy when two hoists are used at the same time.
Protected areas and working limits allow defining protected zones such as production machinery or storage areas, where the crane is not allowed to enter. Working limits build temporary ”virtual walls” at which your crane is designed to stop automatically. These functions help prevent collisions between the crane and valuable equipment near the crane and thus increase safety and prevent possible damage.
Shock load prevention allows smooth load pick-up. The hoist drive monitors the load. If the load is picked up abruptly, the hoisting speed is automatically reduced until the load is lifted. This feature designed to prevent shocks to the load and the crane, and extend the lifetime of the crane’s steel structure and mechanical parts.

In the industrial world that is continually evolving and renewing, many engineering programs are required to keep up with the current technology. One of them is FINITE ELEMENTS Programs.
These programs, where Static, Dynamic, Rigid and Flexible analyzes can make are programs that create designs and projects at optimum level and maximum efficiency by combining engineering and manufacturing, theoretical and practical.
As Arnikon Engineering, to ensure minimum dimensions and high strength to Double girder overhead cranes, single girder overhead cranes, jib cranes, Gantry cranes, ground carriages, hoists and specially designed cranes that we manufacture Systems are optimized through various design and finite element programs in our Numerical Analysis laboratory and delivered to our customers with the assurance of ARNIKON engineering.
