Hengyang Heavy Industry's electric hydraulic windproof iron wedge brake YFX-710/80 friction block is made of high wear-resistant steel

The brake fluid of the electric hydraulic windproof iron wedge brake must be strictly filled according to the original vehicle's specified model of brake fluid when replenishing and replacing. If it is necessary to replace another model of brake fluid, it is necessary to first distinguish the grade of the original and new brake fluid in order to determine whether the oil resistant rubber seal needs to be replaced. Afterwards, before replacing the brake fluid, it is necessary to thoroughly drain the brake fluid from the original vehicle's brake system and clean it with alcohol before refilling with new brake fluid. So we must prevent different types of brake fluid from being mixed and injected into the brake system for use, only in this way can we prevent the brake from failing.

We all know that the brake is actually the braking system in the mechanical operation equipment, mainly responsible for stopping the equipment operation. The windproof brake mentioned here is specifically used for large lifting equipment, and is used to avoid the impact of weather conditions on work during some high wind conditions. Suitable for windproof braking of various rail mounted cranes such as gantry cranes, gantry cranes, loading and unloading bridges, etc. working in the open air at ports, docks, railways, etc. At the same time, it can also work together with anchoring devices, windproof cables, etc., for safety windproof braking measures of cranes in non working conditions. The usage characteristics of windproof brakes: 1. Compact structure and beautiful appearance. 2. Matched with Ed thruster, with excellent action performance, good sealing performance, and shell protection level of IP65. 3. The friction block is made of advanced high wear-resistant steel, with reliable performance. 4. The main swing hinge points are equipped with self-lubricating bearings, which have high transmission efficiency, fast, sensitive, and reliable action, and long service life. 5. Manual release for easy maintenance. 6. Equipped with a travel switch to display the working status.

The brake shoe of the wedge brake relies on the plunger, and the inner end face of the plunger is inclined, in contact with the rollers supported in the grooves on both sides of the isolation frame. When braking, the wheel cylinder piston moves the brake wedge inward under hydraulic pressure, and the brake wedge causes one side of the second roller to roll diagonally inward along the plunger, while the other side moves the second plunger outward for a certain distance in the hole of the brake base plate, thereby pressing the brake shoe against the brake drum. Once the hydraulic pressure of the wheel cylinder is removed, this series of parts will reset individually under the action of the brake shoe return spring.

The YFX series electric hydraulic windproof iron wedge brake is a new type of hub mechanical basic component brake product developed according to the requirements of port lifting machinery. When the product is powered on, the electric hydraulic thruster acts, and the pushrod of the thruster quickly rises, and the iron wedge is lifted by a lever and connecting rod to ensure the normal operation of the crane; When the power is cut off, the push rod of the thruster is under the action of spring force, and the iron wedge is placed on the track through a lever, which blocks the wheels in case of strong winds, providing safety protection. This product uses electric hydraulic thrusters and lever and connecting rod mechanisms to achieve action requirements, with a reasonable structure and reliable action.
