Hengyang Heavy Industry's YFX-700/80 electric hydraulic windproof iron wedge brake has a long service life

The electric hydraulic windproof iron wedge brake is a new type of key mechanical basic component brake product developed according to the requirements of port lifting machinery. The electric hydraulic windproof iron wedge brake is a windproof device that has digested and absorbed advanced technology both domestically and internationally, followed by structural innovation, final design, and innovative crane working conditions.

When it is powered on, the electric hydraulic thruster acts, pushing the push rod to quickly rise and lifting the iron wedge through a lever and transmission mechanism, which will enable the crane to work normally; And when the power is cut off, the push rod of the thruster will be placed on the track through a lever under the action of spring force, and can block the wheels in case of a sudden storm, thus providing safety protection. The electric hydraulic windproof iron wedge brake uses an electric hydraulic thruster, lever, and connecting rod mechanism to achieve the action requirements. It has the advantages of reasonable structure and reliable action, and uses a reasonably shaped iron wedge and high-strength, high hardness friction blocks, which will ensure the windproof ability of the entire machine and have strong windproof ability.

The brake of the electric hydraulic windproof iron wedge brake is equipped with self-lubricating bearings, and its friction blocks are uniformly connected in a card type, so it is very convenient to replace and has high transmission efficiency. At the same time, it also has a manual release device, which is very convenient to operate.

At present, the technology of electric hydraulic windproof iron wedge brakes on the market is mature, with stable performance, and can meet the requirements of mass production. Moreover, the thrusters of the electric hydraulic windproof iron wedge brakes currently produced use a uniquely designed connecting rod as the transmission mechanism, and efficient and wear-resistant friction blocks as the working components. Therefore, it can effectively prevent catastrophic accidents such as the movement and overturning of open-air cranes under strong winds.

This type of brake is safe to use, has strong reliability, and is also a key mechanical foundation component in the high-tech product category. The development of this type of brake has timely filled the gap in China and has been widely used as a windproof device for railed cranes such as gantry cranes, loading and unloading machines, and gantry cranes used in the open air in ports, docks, railways, etc. But the feedback from the people who use it is very good.

The electric hydraulic windproof iron wedge brake is widely used for windproof braking of outdoor medium and heavy lifting machinery in working conditions and auxiliary braking in non working conditions. The electric hydraulic windproof iron wedge brake generally acts on the passive wheel and then applies direct braking, which can effectively prevent the braking wheel from rolling displacement under the action of wind.
