YFX-350/80 ELECTRO HYDRAULIC STORM BRAKING WEDGES BRAKES

YFX series electro-hydraulic windproof wedge brake is a new type of key mechanical foundation brake product developed according to the requirements of port crane. This product is a windproof device for crane working state, which is designed and innovated on the basis of digesting and absorbing foreign advanced technology and carrying out structural innovation.

When the product is electrified, the electro-hydraulic pusher acts, and its push rod rises rapidly, and the iron wedge is lifted through the lever and transmission mechanism to make the crane work normally; When the power is cut off, the push rod of the pusher will place the iron wedge on the track through the lever under the action of the spring force, and the wheel will be wedged for safety protection in the case of sudden storm.

The product adopts electro-hydraulic pusher, lever and connecting rod mechanism to meet the action requirements, with reasonable structure and reliable action. The reasonable shape of iron wedge and friction block with high strength and hardness are adopted to ensure the windproof ability of the whole machine. The brake is equipped with a self-lubricating bearing, and the friction block is connected by clamping, which is convenient to replace and has high transmission efficiency.

Equipped with manual release device, easy to operate. The products have reached the international advanced level through provincial appraisal. At present, after passing the appraisal, the product has mature technology and stable performance, and has been put into mass production. Because this product is a new type of windproof brake with the internationally advanced Ed series propeller as the driving device, the uniquely designed connecting rod as the transmission mechanism, and the friction block with high efficiency and wear resistance as the working element, it can effectively prevent the open-pit crane from moving and overturning under the strong wind raid. It is safe to use and reliable, and it is the key mechanical basic part in high-tech products.

This product is developed for the first time in China, which fills the gap in China and has been declared as a national utility model patent. The certified product is widely used as the windproof device for rail cranes such as gantry cranes, loaders and portal cranes used in ports, docks, railways, etc., and has been well received by users, replacing imports and exporting to earn foreign exchange. In the future, we will focus on improving the processing technology and strive for greater benefits.
