Insufficient braking force issueWhen the braking force of the disc brake is insufficient, the following methods can be used to solve the problem:1. Change the brake pad materialA slightly softer brake pad material can be used to improve the friction coefficient and increase the braking force.2. Remove foreign objects from the debris removal groove of the brake padIf the debris discharge groove of the brake pad is covered by foreign objects, the effect of dust discharge and water scraping will be lost during braking, resulting in a decrease in braking force.3、 Noise during brakingWhen braking, if there is a "squeaking, squeaking" noise, the following methods can be used to eliminate it:1. Add an anti noise pad between the brake caliper piston and the brake lining to create a tilt on the piston. This ensures flexible contact between the brake pads and brake discs during braking, ensuring that there is no abnormal noise in the brake pads under normal wear and tear conditions.2. Choose a brake pad material that is softer and less dense.3. When braking, the brake pads may move to one side and there may be a knocking sound. This is due to the excessive gap between the brake pad and the caliper body, which can be eliminated by electroplating solder. However, it should be noted that the solder should be coated on the side opposite to the direction of travel to prevent failure under the action of braking force.SBD brake installation siteElectromagnetic failure protection disc brake:3SE; 4SE; 5SE; 450SE; 56SE; 560SE; 561SE; ST1SE; ST2SEHydraulic fail safe disc brake:3SH; 4SH; 5SH; 450SH; ST1SH; ST2SH; ST3SH; ST4SH; ST5SH; ST10SH; ST16SH; ST25SH; 904SH;ST40SHPneumatic fail safe disc brake:3SP; 4SP; 5SP; 450SPHydraulic direct acting disc brake:ADH60; ADH90; ADH120; DADH75; DADH80; DADH90; DADH120; DADH195; DADH350Pneumatic direct acting disc brake:ADP60M; ADP61M; ADP62MPneumatic caliper disc brakeCQPL12.7A-A; CQPL12.7A-B; CQPL12.7B; QPL12.7A-A; QPL12.7A-B; QPL12.7-A; QPL12.7-B;QP30-D; QP25.4-D; CQP30-D; CQP25.4-D; PDA5; PDA10; PDB5; PDB10; PDB19; PDC5; PDC10Electromagnetic caliper disc brake:DCPZ12.7-250; DCPZ12.7-300; DCPZ12.7-400Hydraulic caliper disc brake:SB (YQP) 50; SB (YQP) 100; SB (YQP) 160; SB (YQP) 250; SB (YQP) 315; SB (YQP) 400;SBD safety brake:SBD100-A; SBD125-A; SBD160-A; SBD200-A; SBD250-A; SBD-B; SBD160-B; SBD250-C; SBD365-C; SBD425-C; SBD80-B; SBD160-B; SBD250-C; SBD365-C; SBD425-C; SBD120-D; SBD240-DThere are two types of brake linings for disc brakes: one is that the brake band is made of asbestos rubber steel wire mesh, the other is that the brake pad is made of asbestos resin, and the non asbestos brake pad and brake pad are of clip in type and riveted type, which are safe, reliable, easy and fast to replace.Its characteristics are:1.

Electric hydraulic block brake: Using hydraulic electromagnetic blocks instead of long travel block brake electromagnets, there are two types: YWZ (hydraulic push rod) and YDWZ (hydraulic electromagnet). The YWZ type brake is stable, noiseless, and small in size, making it suitable for operating and rotating mechanisms. Due to its slow braking action, it is not suitable for the use of lifting mechanisms to prevent hook slipping. The YDWZ model has good performance in various aspects and does not require frequent adjustments. It only requires a DC power supply.2. Belt brake: when the overall dimensions are affected and the braking torque is required greatly, the belt brake can be considered. This kind of brake device is commonly used on Mobile crane. The disadvantage of band brakes is their low safety, and breaking the brake band can cause serious consequences.3. Disc brake: the disc brake is widely used due to its large braking torque, small overall dimensions, large friction area and small wear. Disadvantages of disc brake: the electromagnet coil is easy to heat, impact, noise and parts are easy to be damaged when the temperature rises.4. The brake ring and brake wheel of the conical brake are both conical, and the conical brake is a part of the conical electric motor. The reason why the rotor and stator of the conical electric motor are designed and made into conical is to obtain a simple and lightweight structure, convenient assembly and adjustment, and inseparable from the electric motor. The conical brake is currently widely used by electric hoists, CD, AS DH electric hoists all use conical brakes.The hydraulic push rod brake pads for cranes are mainly made of asbestos material with copper wire inside, which is sturdy and not slippery

Working principle 1: The power supply of the thruster is connected, and the motor rotates to drive the impeller to generate pressure oil, which drives the piston and connecting rod to run upwards, generating and maintaining its thrust when reaching the predetermined stroke. When the power supply is disconnected, the motor and impeller stop rotating and no longer generate pressure oil. The piston and connecting rod return to their original position under external force. 4. Installation and adjustment (see Figure 1) 4.1 When the thruster leaves the factory, the working oil is already installed and can be used directly. Due to the decrease in oil, the technical value of the thruster may change, and even cannot be started. Therefore, it is prohibited to open the oil plug or overflow plug without permission. 4.2 The thruster is generally installed vertically (the motor should be below), and can also be installed tilted or horizontally. However, it must be noted that when installing tilted or horizontally, the balance chamber should be facing upwards. It is necessary to ensure that the thruster can swing as a whole, and the piston rod is not allowed to bear radial force. 4.3 The connecting rod of the thruster can rotate, and the base can rotate 90 degrees. Where can YTD2-30/5 thrusters be sold? YTD2-23/5-YTD2-30/5 After the base rotates, the center height is extended by 8mm. 4.4 When wiring, the cable should enter the junction box through the stuffing box, remove the thruster junction box cover (there is a wiring diagram on the reverse side), connect the Three-phase electric power AC power supply according to the parameters as required (no requirements for phase sequence), and connect the internal and external wires (the power cable specification should not be greater than 4 × 2.5 mm2)The Ed series thrusters are produced and manufactured by a company that imported the full set of design and manufacturing technology from the former West German EMG company, and comply with the German DIN15430 and JB/T 10603-2006 standards.

For example, in a lifting mechanism, keep the lifting load stationary in the air; In the luffing mechanism of the boom crane, maintain the boom in a certain position and remain stationary; It plays a role in preventing wind and sliding for outdoor cranes.(2) Stopping power: consumes kinetic energy of the moving part and converts it into frictional heat energy through the friction pair, so that the mechanism can quickly stop moving within a certain time or a certain stroke. For example, the braking of various mechanisms in motion.(3) Falling weight effect: The braking force balances with gravity, causing the moving body to descend at a stable speed. For example, the downhill speed of a truck crane.Jiaozuo Brake FactoryThe essence of a brake is to produce a braking effect through the friction of the friction pair. According to work needs, or by converting kinetic energy into frictional heat energy consumption, the mechanism can rest in motion; Or balance the force through Stiction to keep the mechanism in its original static state.Its structural characteristics are: one group of brake friction pairs is connected to a fixed frame; The other group is connected to the rolling axis of the mechanism.

In the selection process of crane brakes, due to the wide range of practical applications of crane brakes, unless there are special requirements for the brakes during crane construction, standard brakes are usually selected, and the selection of brakes is required to comply with national standard systems. Meanwhile, in the selection process, due to the different brake specifications of different models and types of cranes, it is necessary to focus on the size and specifications of the crane brake. If the size specifications do not meet the standards, it will not only be impossible to install, but even if it can be installed in use, there will be significant safety hazards.(2) Safety principle. When selecting a crane brake, the key consideration is whether the brake is safe enough in practical application, analyzing the actual application performance of the crane brake, and ensuring that the brake is safe and reliable enough in practical application. Due to the large workload of cranes and their ability to carry large loads, there are requirements for the construction materials of crane brakes. It is necessary to focus on the stiffness and safety of the brake materials. If conditions permit, performance testing is required, especially for some core components in the brakes. It is necessary to ensure that all components comply with national regulations and standards, such as brake rods, brake arms, springs, etc.(3) Adaptability principle. For the crane brake, as the core component of the crane, the brake has a direct or indirect connection with other components. Therefore, it is necessary to focus on analyzing the compatibility between the crane brake and other components. In the process of selecting brakes, it is necessary to fully consider the matching issues between various systems in the crane, whether the brakes meet the adaptation standards, including the performance of each system and the application environment.Safety selection of crane brakes2.1 Adjusting the braking torqueTo ensure the safety of crane brake selection, it is necessary to analyze the torque performance of the brake. The selected brake needs to match the selection standard, measure the operating size of the brake torque, and based on this, adjust the torque value of the brake through the method of marking.
