As an important industrial handling equipment, the safety protection device of internal combustion forklift is related to the life safety of operators and production stability. The design and standardized use of key components such as anti-rollover system and emergency brake device are the core of ensuring safe operation.
The anti-rollover system is the key to prevent the internal combustion forklift from rolling over when it is overloaded, on a slope or turning. Its core design needs to combine sensor technology and mechanical structure. The angle sensor monitors the tilt angle of the forklift in real time. When the tilt angle exceeds the safety threshold, the system automatically triggers an alarm and restricts operation. For example, the hydraulic system can control the fork arm to lower the load height and reduce the risk of center of gravity shift; some advanced anti-rollover systems are also equipped with dynamic stability control systems to adjust the tire grip in real time according to the vehicle's motion state. In terms of mechanical structure design, the reinforced frame and counterweight layout need to ensure that the forklift maintains a stable center of gravity under extreme working conditions. At the same time, the limit device can prevent the forklift from over-lifting and causing imbalance.
The emergency brake device of the internal combustion forklift requires high reliability and fast response capabilities. The hydraulic brake system is a common design that transmits pressure to the wheel brake through the master brake cylinder to achieve rapid deceleration. To improve safety, modern forklifts often use dual-circuit braking systems. When one circuit fails, the other can still ensure basic braking functions. In addition, the parking brake must be independent of the service brake, usually using a mechanical cable or spring energy storage design to ensure that the vehicle does not slide on a slope or when parked for a long time. Parameters such as brake pedal travel and braking force distribution must be accurately calculated and tested to balance the braking effect and operating comfort.
The materials of the anti-rollover system and emergency brake device directly affect their performance and life. The sensor housing must be made of high-strength, electromagnetically resistant engineering plastics or metal materials to ensure normal operation under harsh environments such as vibration and high temperature. The friction pads of the brake system must be made of high-temperature resistant, high-friction composite materials, such as ceramic-based or semi-metallic materials, to avoid performance degradation due to overheating during braking. The forklift frame and counterweight parts must use high-strength steel, and the structural strength must be ensured through welding technology, while anti-corrosion coatings are used to extend the service life.
When installing the anti-rollover system and emergency brake device for internal combustion forklift, the manufacturer's technical requirements must be strictly followed. The angle sensor should be installed near the center of gravity of the forklift to ensure accurate measurement data; the layout of the brake line should avoid bending and wear to keep the brake fluid flowing smoothly. After all safety devices are installed, functional tests are required, including tilt angle alarm accuracy, braking distance test, etc. At the same time, regularly check whether the fixing bolts of the device are loose and whether the line connection is firm to prevent the displacement or failure of components due to vibration.
Operators need to undergo professional training and be familiar with the functions and operation methods of the anti-rollover system and emergency brake device. Before operation, check whether the system indicator light is normal, and test the brake pedal stroke and braking force. During driving, overloading and speeding are strictly prohibited, and sudden steering and sudden braking are avoided to prevent the anti-rollover alarm from being triggered. The emergency brake device is only used in sudden dangerous situations, and frequent use may shorten its service life. In addition, forklifts should be regularly inspected for safety to ensure that the safety devices are in good working condition.
The sensors of the anti-rollover system need to be cleaned regularly to prevent dust and oil from affecting the detection accuracy; the brake system needs to check the brake fluid level and quality, and replace the deteriorated fluid in time. When the brake friction pad is worn to the limit mark, it should be replaced immediately to avoid damaging the brake disc. Mechanical parts such as brake cables and limit devices need to be lubricated regularly to prevent rust and jamming. Maintenance records should be archived in detail to track equipment status and prevent potential failures.
