The YWZ4 series provides secure holding during loading\/unloading operations and emergency stopping capability for hoist, trolley, and bridge motions.<\/p>\n\n\n\n

\u00c9quipement de construction et de levage<\/h3>\n\n\n\n

Deployed in tower cranes<\/strong>, construction hoists<\/strong>et material elevators<\/strong> where exposure to dust, vibration, and varying temperatures demands robust braking performance. The IP65 protection rating ensures reliable operation in challenging construction environments.<\/p>\n\n\n\n

Sid\u00e9rurgie & Acier<\/h3>\n\n\n\n

Suitable for ladle cranes<\/strong>, charging cranes<\/strong>et ingot handling equipment<\/strong> in high-temperature environments. Optional high-temperature configurations with heat-resistant brake linings extend operational capability up to 300\u00b0C ambient temperature.<\/p>\n\n\n\n

Minier & Manutention de mati\u00e8res en vrac<\/h3>\n\n\n\n

Trusted in stackers-reclaimers<\/strong>, conveyor systems<\/strong>et mine hoists<\/strong> where heavy loads and continuous operation require dependable braking. The fail-safe design ensures load security during power fluctuations common in mining operations.<\/p>\n\n\n\n

Fonctionnement des freins \u00e0 tambour s\u00e9rie YWZ4<\/h2>\n\n\n\n

The YWZ4 series operates on a proven spring-applied, hydraulic-release<\/strong> principle that ensures fail-safe performance in critical lifting applications.<\/p>\n\n\n\n

Phase de freinage (Arr\u00eat)<\/h3>\n\n\n\n

When electrical power is disconnected or the thruster is de-energized, powerful compression springs<\/strong> force the brake arms to pivot, pressing the brake pads firmly against the rotating brake wheel. The resulting friction generates the rated braking torque, securely holding the load in position.<\/p>\n\n\n\n

Phase de d\u00e9blocage (Alimentation \u00e9lectrique)<\/h3>\n\n\n\n

Lorsque le propulseur re\u00e7oit de l\u2019\u00e9nergie, le moteur interne entra\u00eene une pompe hydraulique qui \u00e9tend la tige du propulseur, surmontant la force du ressort et lib\u00e9rant les plaquettes du frein de la roue. Le syst\u00e8me hydraulique assure une action de d\u00e9blocage fluide et contr\u00f4l\u00e9e, minimisant les chocs m\u00e9caniques sur le syst\u00e8me d\u2019entra\u00eenement.<\/p>\n\n\n\n

Calcul du couple<\/h3>\n\n\n\n

Le couple de freinage des freins de la s\u00e9rie YWZ4 est calcul\u00e9 selon la formule :<\/p>\n\n\n\n

T = F \u00d7 (D\/2) \u00d7 \u03bc \u00d7 n<\/strong><\/p>\n\n\n\n

O\u00f9 :\nT = Couple de freinage (N\u00b7m)\nF = Force de ressort (N)\nD = Diam\u00e8tre de la roue de frein (m)\n\u03bc = Coefficient de friction (typiquement 0,35-0,45)\nn = Nombre de surfaces de friction<\/p>\n\n\n\n
