Safety Failure Protection Disc Brake http://jzszdq.com/ The service brake is equivalent to the brake pads on a car. When the car needs to stop, if the brake pads fail, it will cause the car to fly out and collide with pedestrians, resulting in a traffic accident. The use of driving is also like this, when it is necessary to stop, the brake needs to be activated to stop the driving. Proper use of brakes during driving is not only beneficial for ensuring driving safety, but also for saving fuel, reducing tire wear, and preventing mechanical damage. There are mainly two types of brakes on the market now: disc brakes and drum brakes. Their functions are the same, but their working principles are not exactly the same. The general working principle is to use the mutual friction between non rotating components connected to the vehicle body (or frame) and rotating components connected to the wheels (or transmission shaft) to prevent the rotation or tendency of the wheels. The following mainly introduces the working principle of disc brakes. Currently, the YWZ series electric hydraulic drum brakes are commonly used as driving devices in China's industrial brake industry using Ed and YTD series electric hydraulic thrusters. Due to the long-term continuous operation of this series of brakes, the motor load duration is long, the temperature rises, accelerates the insulation aging of the motor, accelerates the failure of hydraulic seals, causes oil leakage, and leads to relatively more faults. Often, the motor overheats and burns out, causing faults in the electric hydraulic thruster, affecting operation, and even causing accidents; When used in lifting equipment, after the thruster motor is powered off, due to the inertia of the thruster motor rotor and impeller, the hydraulic oil pressure relief slows down, the damping push rod and piston descend, and the brake closing lags behind, resulting in untimely braking and often causing the phenomenon of slipping hooks. The YWZZ series cold state (maintenance) brake adopts the EdZ series cold state electric hydraulic thruster as the driving device. The EdZ thruster is equipped with a DC electromagnet holding device. During the operation of the brake, the thruster motor only completes the process of opening (releasing) the brake before shutting down the thruster motor, and the brake is maintained in the open state by the DC electromagnet holding force. However, the current of the DC electromagnet is small, which lowers the temperature rise of the thruster and prolongs its service life; When braking, the electromagnet loses power. As the motor has already been cut off, the hydraulic oil has been completely released, and the push rod and piston are no longer affected by hydraulic oil damping and quickly descend. The brake quickly brakes, improving the phenomenon of slipping hooks. The YWZZ series cold state (maintenance) brake can be widely used in mechanical equipment such as lifting, belt transportation, port loading and unloading, metallurgy, mining, and construction. Especially suitable for deceleration and parking braking of various mechanical equipment and lifting mechanisms that work for long periods of time or have relatively long working hours. This series of brakes complies with JB/ZQ6406-2006 and JB/T7021-2006 standards, and the EdZ actuator complies with JB/T10603 standards. http://jzszdq.com/
Usage condition 1: Environmental air temperature: -25 ℃ to+50 ℃. 2. There should be no flammable, explosive, or corrosive gases in the surrounding work environment, and the relative humidity of the air should not exceed 90%. 3. The power supply is three-phase AC 380V 50Hz, and the voltage fluctuation should not exceed ± 10% of the rated value. 4. The altitude of the usage location shall not exceed 2000m. 5. Applicable working system: continuous working system (S1) and intermittent cycle working system (S3-60%). Tower cranes have been used in Europe. Cranes mainly include lifting mechanisms, operating mechanisms, variable amplitude mechanisms, slewing mechanisms, and metal structures. The lifting mechanism is the usual working mechanism of a crane, which is mainly composed of a hoisting system and a winch. It can also lift heavy objects through a hydraulic system. The operating mechanism is used to vertically and horizontally transport heavy objects or adjust the working position of a crane, usually consisting of an electric motor, reducer, brake, and wheels. The slewing mechanism is only equipped on the boom type crane. When the boom is lifted, the amplitude decreases, and when it is lowered, the amplitude increases. There are two types of slewing mechanisms: balanced slewing and unbalanced slewing. The slewing mechanism is used to rotate the arm frame. At the beginning of the 20th century, it was composed of a driving device and a slewing bearing device. The metal structure is the skeleton of the crane, and the main load-bearing components such as the bridge, boom, and gantry can be box shaped or truss structures, or web plate structures. Some can be supported by steel beams. Electromagnetic failure protection disc brake:

Product Introduction
RHI series wheel clamp, also known as wheel edge brake, is mainly used for windproof braking and auxiliary braking of outdoor medium and heavy lifting machinery under working conditions and non working conditions. Generally applied to passive wheels for direct braking, it can effectively prevent the braking wheels from rolling displacement under wind force. Structurally, it adopts spring upper brake and hydraulic release brake, which has the advantages of SHI type. Y
