Manufacturer of hydraulic brake for port crane

Hydraulic brakes, as the name suggests, play a role in speed control and braking in various devices that use them. The concept of control should be fully reflected in the brakes. All movements, planned goals, must find results on the brakes. There are many manufacturers producing brakes, and according to the different functions of the site, many series of brakes have also been derived. With the promotion of design and technology personnel, they are gradually improving and progressing. The following will gradually introduce the history and evolution of each series of brakes, as well as the new models and functional features.

Main characteristics of hydraulic brakes for lifting cranes

1. The automatic tile following device and interlocking backhaul equalization device (patented technology) can always maintain equal backhaul of both sides of the tiles without adjustment, completely avoiding the phenomenon of one brake pad floating against the brake wheel due to uneven backhaul

2. Its main swing hinge points are equipped with self-lubricating bearings, which have high transmission efficiency and long service life, so there is no need for lubrication during use.

3. The brake springs arranged in the square tube are all equipped with scales, so users can easily read the braking torque value, which can reduce the trouble of measurement and calculation.

4. The brake pad is a card mounted integral shaped structure, which is very convenient and fast to replace. It is also equipped with different materials such as semi metal (non asbestos) hard and semi hard, soft (including asbestos, non asbestos) brake pads for users to freely choose from.

5. This new type of armature follower device can always maintain a good fit between the armature and the magnetic yoke. The disc brake will gradually replace the drum brake, mainly due to the advantages and disadvantages of the disc brake and drum brake. The disc brake has a large and stable braking force under the hydraulic assistance. The hydraulic brake of the crane has good braking performance on various roads. Its braking efficiency is far higher than that of the drum brake. Moreover, the air directly passes through the Disc brake disc, so the heat dissipation of the disc brake is very good. However, compared with the drum brake, the structure of the disc brake is more complex, with higher requirements for the brake caliper and Plumbing, and its cost is higher than that of the drum brake. Compared with the disk brake, the brake efficiency and heat dissipation of the drum brake are much worse. The stability of the brake force of the drum brake is poor. The brake force varies greatly on different roads, and it is not easy to control. Moreover, due to poor heat dissipation, drum brakes exhibit thermal decay. Of course, drum brakes are not entirely useless. Their major applications are in the manufacturing of CNC machine tools, as stepper motors do not require conversion and can directly convert digital pulse signals into angular displacement. Therefore, they are considered ideal actuators for CNC machine tools. The output torque of early stepper motors was relatively small and could not meet the needs. In use, a hydraulic pulse motor was formed together with a hydraulic torque amplifier. With the development of stepper motor technology, the hydraulic brake of lifting cranes has become an irreplaceable executive component that can be used alone in the system. For example, the stepping motor is used as the drive motor of the CNC milling machine feed Servomechanism. In this application, the hydraulic brake stepping motor of the crane can complete two tasks at the same time, one is to transmit torque, the other is to transmit information. The stepper motor can also be used as the driving motor for the synchronous system of the CNC worm wheel grinding machine. The brake is a type of brake applied to the traveling crane (i.e. lifting equipment). When it is necessary to stop working, the equipment is subjected to certain resistance to stop mechanical operation. Its use is directly related to the safety of personnel and equipment, so personnel working on the use of service brakes must have a detailed understanding.

The hydraulic brake and service brake of a crane are equivalent to the brake pads on a car. When the car needs to stop, the brake pads fail, causing the car to fly out and collide with pedestrians, resulting in a traffic accident. The same applies to the use of the traveling crane. When it is necessary to stop, the brake needs to be activated to stop the traveling crane. Proper use of brakes during driving is not only beneficial for ensuring driving safety, but also for saving fuel, reducing tire wear, and preventing damage to machinery components
