Overhaul and adjustment of crown block brakeAccording to the requirements of crane safety regulations, the brakes should be regularly inspected. During the installation, debugging, and use of the brake, special attention should be paid to the following adjustments:(1) Adjustment of braking torque: The braking torque must be adjusted according to the specified requirements, which is the basic work during the installation, debugging, and operation of the brake (checking for any changes). According to the standard requirements of the brake, the braking torque value should have a clear scale, and the torque value can be adjusted according to the scale or line of the torque value.(2) Adjustment of the working stroke of the driving device: The working stroke of the brake driving device should be adjusted at the working environment temperature, and its rated working stroke value should be indicated in the product manual or on the driving device. During use, it is necessary to regularly observe the changes in the working stroke based on the frequency of use. Especially for brakes without an automatic compensation mechanism for brake pad wear, the working stroke of the driving device must not be equal to its maximum stroke (rated stroke), otherwise serious consequences of loss of braking force will occur. When stopping after use, the compensation stroke of the driving device should be checked (the rated stroke of the driving device minus its working stroke). If the compensation stroke is too small, it should be adjusted immediately to avoid reducing the compensation stroke and losing braking force due to cooling deformation caused by thermal expansion of the brake pad during use.(3) Adjustment of compensation mechanism: The installation of automatic compensation mechanism for brake pad wear (referred to as compensation mechanism) on the brake can avoid frequent adjustment of the working stroke of the driving device during the use of the brake. However, the compensation mechanism should be adjusted and reliably fixed, otherwise if the working stroke of the driving device is not adjusted in a timely manner after the brake pad is worn, the braking force will be lost. The adjustment of the compensation institution should be made according to the product manual, and regular observation should be made to see if there are any changes during use.(4) Adjustment of backlash: After the working stroke of the brake drive device is adjusted, the total backlash of the brake pad is also determined accordingly. The backlash on each side of the brake pad should be basically equal to avoid friction caused by large backlash on one side and "unable to open" on the other side, which can cause a sharp increase in unilateral friction temperature, reduce braking performance, and exacerbate wear of the brake pad. Therefore, the backlash should be adjusted according to the product manual.Electric hydraulic brakeYWZB YWZ3B YWZ4B YWZ5 YWZ8 YWZ9 YWZ12 YWZ13 YW YWL TYWZ2 YWPElectromagnetic block brakeJZ (TJ2A) MW (Z) ZWZAZWZ2 ZWZ3ADCW3Electromagnetic failure protection disc brake5SE 561SE 560SE 56SEDCPZ12.7 4SE 3SE ST1SE ST2SE 450SEHydraulic failure protection disc brake5SH 4SH 3SH 450SH ST1SH ST2SH ST3SH ST4SHSB (YQP) SBDST5SH ST10SHST16SHST25SHST25SH-AST40SH904SHSBBElectro hydraulic arm disc brakeYPZ2 I, II, IIIYPZ2 IV, V, VIPneumatic caliper disc brake QP12.7 5SP4SP3SP450SPPDADP60M-ADP61M-ADP62MHydraulic direct acting disc brake DADH75ADH60ADH90ADH120DADH80DADH90DADH120DADH103DADH195Electric hydraulic thrusterYT1 EdMYT1 hydraulic thruster motor modelBO62Z YDT80-2 ASF82A ASF102A B112Z A028012A028022 three-phase asynchronous motorExplosion proof electric hydraulic thrusterBYT1 BED

Precautions for use, maintenance, and upkeep of electric hydraulic thrusters1. The brake lining of the electric hydraulic thruster is a vulnerable component, and its usage limit should not be less than 0.8mm for the friction material part. Otherwise, the brake lining needs to be replaced.2. When cleaning the vehicle, never use cotton wool to clean the surface of the brake disc, to avoid polluting the brake lining and causing brake performance failure.3. The brake fluid of the electric hydraulic actuator in the reservoir should not be lower than the minimum limit. When adding brake fluid, attention should be paid to cleanliness, and dust and dirt should not be mixed into the reservoir to avoid blockage of the brake system and brake failure.4. Electric hydraulic thrusters should regularly replace vulnerable parts to prevent rubber parts from aging, usually within 1-2 years.5. During maintenance and upkeep of electric hydraulic thrusters, the tightening torque of fasteners should be checked at all times to prevent loosening.

Use and Adjustment of Hydraulic Brakes1. Loosen the brake torque spring, manually lift the push rod triangle, adjust the upper adjustment screw to make the brake port gap 1.5 millimeters, and adjust the lower limit screw of the brake frame to evenly distribute the brake port gap on both sides; Adjust the torque spring to the required scale and tighten all locking nuts.When the brake pad wear meets the requirements, replace the brake pad and adjust according to the above steps; During the process of brake pad wear, due to brake pad wear, the brake triangle plate drops. When the accelerator rod drops close to the compensation mark, adjust the gap in a timely manner.

Precautions for the use of hydraulic brakes1. Lubricants are often added to electromagnetic brakes.2. Regularly check the length of the armature stroke. Because during the operation of the brake, the travel length of the armature will increase due to wear on the moving surface. When the length of the armature stroke cannot reach the normal value, it is necessary to adjust it to restore the minimum gap between the brake surface and the rotary table. If the stroke length of the armature increases above the normal value, it may greatly reduce the suction force.3. If a worn brake surface is replaced, the minimum gap between the brake surface and the rotary table should be adjusted from the beginning.4. Regularly check the tightening degree of the bolts, especially tighten the bolts of the electromagnet, the bolts of the electromagnet and the shell, the bolts of the magnetic yoke, the bolts of the electromagnet coil, and the wiring bolts.5. Regularly check the mechanical wear status of movable components and remove dust, burrs, and dirt from the surface of electromagnetic components.

Talking about Brake Jitter of Disc BrakeBrake judder of disc brake is a typical brake system fault, which involves the generation and transmission of brake vibration and noise as well as the subjective feelings of passengers. Brake judder can accelerate the aging and fatigue damage of related components in the transmission path, affecting the driving comfort of the vehicle.The issue of brake jitter is generally caused by lower order disturbances in the braking system. Low frequency shaking is mainly caused by brake torque fluctuations, and the frequency of shaking is in some order relationship with the vehicle speed. The frequency is below 100 Hz, and most shaking occurs near the vehicle speed of 60 km/h.Brake judder can generally be divided into cold judder, hot judder, new car judder, wet judder (when there is water between the friction pairs), and rust judder according to the phenomenon. Cold shaking is mainly caused by irregular geometric dimensions of the brake disc or shaking of the friction plate, which affects the fluctuation of brake pressure and torque. Most cold shaking is a 1-5 order low-frequency vibration. Thermal jitter is caused by local thermal instability of the brake disc, resulting in thermal deformation. Thermal jitter generally occurs after multiple emergency brakes during high-speed driving, and the temperature of the brake disc rapidly increases. New car shaking is generally caused by uneven friction between the brake pads and brake discs during the new car's break-in period. Wet shaking is mainly caused by uneven braking pressure caused by water film between the brake disc and friction plate during rainy days, resulting in brake torque fluctuations. Rust shaking is caused by the Friction torque fluctuation between the friction plate and the brake disc after the brake disc is rusted. Generally, the shaking disappears after the rust is removed.

Selection of installation methods for electric hydraulic thrusters1. Vertical installation: The piston rod connecting block faces upwards;2. Horizontal installation and any position in the middle: the main parameter label faces upwards; All push rod connection blocks of thrusters can rotate.Regardless of the installation position, the piston rod cannot withstand any force to avoid affecting its effectiveness and lifespan.
