With the continuous development of China’s infrastructure, the demand for skilled technical personnel has been steadily increasing. At present, there is a significant shortage of professionally trained operators of construction machinery such as excavators and forklifts, making it imperative to quickly fill these positions. Teachers at the Vocational Skills College of Sichuan University Science Park point out that, in terms of skill development, mastering forklift operation is not particularly challenging; in fact, securing a job in this field is quite straightforward. However, in actual work settings, since forklifts are classified as medium-sized construction equipment, safety considerations—particularly those related to safe operation—must never be overlooked. With that in mind, let us begin by examining forklift braking systems and explore the key points of common knowledge regarding forklift brakes that operators need to pay attention to.

Forklift braking systems are an essential safety accessory for safe forklift operation. For routine tasks, the braking system is typically the first component operators check before starting work. So, what specific issues should users of forklifts equipped with electromagnetic brakes pay close attention to during operation? Let’s take a comprehensive look.

Working Principle of Electromagnetic Brakes

For forklifts equipped with electromagnetic brakes, the braking function is primarily achieved through electromagnetic action. The brake pads, positioned in the middle, are connected to the motor shaft via bearings, while the magnetic disc and friction pads are directly secured to the motor end cover. During normal operation, when no current flows through the disc coil, a small gap remains between the two faces of the brake pads, having little impact on the forklift’s performance. However, when braking is required, current is applied to the disc coil, generating an electromagnetic force that overcomes the spring pressure. As a result, the brake friction pads gradually press toward the center, closing the gap under pressure and thereby achieving the braking effect.

Precautions for Using Electromagnetic Brakes

Typically, electromagnetic brakes are pre-assembled with fixed specifications, and proper adjustment can maintain a high braking torque, ensuring that the forklift’s braking distance remains under 1 meter even when operating at full load and high speed. However, it is important to note that electromagnetic brakes experience significant wear during daily use; therefore, over prolonged operation, regular inspection of the brake pad specifications is essential to verify that no severe wear or loosening has occurred. Only in this way can the braking function be reliably maintained, thereby safeguarding operator safety. In addition, for forklifts used frequently, periodic calibration of the electromagnetic brake pads is also necessary to prevent failures such as insufficient braking force, which could create unnecessary hazards during operations.

Maintenance Precautions for Electromagnetic Brakes

Braking equipment itself is a particularly important maintenance focus; therefore, in daily maintenance operations, it is essential to rigorously perform maintenance on electromagnetic brakes. It should be noted that, since electromagnetic brakes rely primarily on electromagnetic force for braking, their magnetic components require thorough and meticulous upkeep. To ensure that braking performance remains unaffected, operators must constantly monitor the condition of these magnetic components during maintenance and, when necessary, carry out timely servicing or replacement. In addition, special attention should be paid to the operating environment: forklifts equipped with electromagnetic brakes should avoid working in high-magnetic-field environments. This is primarily to prevent magnetic fields from interfering with braking performance and to protect the brake’s functionality from damage.

Forklift operation demands both skill and sound judgment; while skill can be honed through consistent practice, achieving more rational and efficient operation requires continuous reflection on experience and the systematic standardization and fine-tuning of operating procedures. Instructors at the Sichuan University Science and Technology Park Vocational Skills Academy emphasize that, whether it’s forklift driving or maintenance, every aspect should be optimized and refined through attention to everyday, seemingly minor tasks. By ensuring scientifically sound operating practices, not only can work efficiency be improved, but the forklift’s upkeep and maintenance can also be better assured.
