1 TARIFF SAFETY SYSTEM FOR FORKLIFTS TECHNICAL AREA 5 The invention concerns safety during load lifting in industrial machinery, particularly forklifts. It relates to a system aimed at increasing safety measures, particularly regarding the load curve and lifting capacity. Load sensing and height determination systems define safe lifting limits based on height. It is related to a safety system that works in integration with sensors. The system provides safety in construction machinery. 10 to improve standards, minimize operator errors and prevent workplace accidents It is being developed. STATE OF THE ART Ensuring workplace safety in industrial machinery, especially forklifts, is crucial today. For this purpose, information regarding the load curve and lifting capacity is generally provided to operators for occupational safety. This information is provided through labels or manual guides. However, these methods... It depends on the operators' attention and compliance with the rules. Operators must be aware of the height and weight. If it violates its limits, any warning or intervention on the machine will be prohibited. There is no mechanism in place. This situation frequently leads to serious workplace accidents such as forklift rollovers. This leads to... Current systems utilize load sensing, height measurement, and combining these two parameters. There is no integrated system that automatically determines safe lifting limits. 25 While some modern forklifts are equipped with weight measuring systems, these systems often fail to measure height. It will work in conjunction with other systems to alert operators or automatically stop the process when the load limit is exceeded. There is no mechanism to stop it. Moreover, current technologies are highly advanced in the sector. This also brings costs with it. These shortcomings necessitate raising safety standards and This shows that there is an important area for development in terms of preventing workplace accidents. 30 In the known state of the art, the invention is "Innovation in forklifts" with application number TR 2013 / 03817.

These elements are connected to each other. By working in an integrated manner, they limit the maximum load capacity of the forklift, both in terms of weight and... It continuously monitors the height. All components of the system, including the forklift, are 25 It is designed to fit the existing structure and can be easily assembled. The weighing system (1) is mounted behind the forklift forks. This system lifts the forklift. It measures the weight of the load and transmits this data to the load sensor cell (3). Load Sensor (2): It works integrated with the weighing system (1) and accurately measures the load amount 30 The Load Sensor Cell (3) detects the detected load information by converting it into digital data. It transmits to the operator. This cell (3) is connected to the forklift's control panel. The height sensor (4), It is mounted on the forklift's lifting mechanism. This sensor (4) monitors the forks It continuously monitors its altitude and detects situations that exceed safe limits. 35 The load is picked up with the forklift forks, then the load cell (2) attaches the load to the forks. It detects this situation and transmits it to the load sensor cell (3). Load sensor cell (3) by converting the perceived load to the required unit type and displaying it to the operator via the instrument panel. It transmits the load. The operator, seeing the weight of the load, uses the load curve specified within the framework of occupational safety. According to the graph, the operator knows the highest point at which the load can be lifted, but the operator can determine the maximum point. When it tries to exceed the high lifting point, the height sensor (4) is activated, Since it is possible to determine what height can be reached with what weight using the height sensor (4), 5 If the operator exceeds the weight-height balance, the sensor (4) will send the weighing system (1) It sends a signal to shut down the machine. This helps prevent workplace accidents. and a safe working environment is provided. The system continuously adjusts the weight loaded onto the forklift forks and the height at which the forks are raised by 10. It operates on the principle of monitoring. When the operator begins to lift a load: • The weighing system (1) is activated and measures the weight of the load. • The measured data is detected by the load sensor (2) and the load sensor cell (3) It is transmitted digitally to the operator via. 15 • At the same time, the height sensor (4) measures the current height of the forks, enabling the system It checks the specified safe weight and height limits. If the weight and height being lifted exceed the defined safe limits, the system will... It operates as follows: 20 • Audible warning mechanism alerts the operator audibly when the lifting level is risky. A warning is given. • The locking mechanism will activate if the operator continues to lift the load despite the audible warning. If it does, the system automatically activates and the forklift's lifting mechanism rises 25 By locking them down, they prevent workplace accidents. Thanks to this structure, the system ensures the safe lifting of the load and both It prevents accidents such as forklift tipping over, as well as potential malfunctions in the machine.
