福彩3d www.bowqa.com 應用APPLICATION



●YW-E系列電力液壓鼓式制動器廣泛應用于各種大中型室外起重機的大車運行機構,具有優越的減速制動性能和理想的防風制動效果;該產品還可用于大型特種起重機的大、小車運行機構,可實現平穩的減速制動和可靠的維持制動;該產品用于皮帶運輸的工作制動也具有理想的制動性能。
●YW-E系列制動器為兩步式制動裝置。一制動,施加一個較小的(可根據需要在規定范圍內調整)制動力矩,進行較平穩的減速制動,待機構停止運動后,二制動開始,并增加一個制動時間,可根據實際需要通過阻尼油缸回路中的單向調速閥進行調整(調整范圍為1-15秒)。
APPLICATION
●Two-step, Delayed electro-hydraulic drum brakes can be extensively used on large/middle outdoor cranes, having excellent decelerati-on braking and storm braking performance. It can also be used on large and middle special cranes , realizing stable deceleration braking and maintenance braking. ldeal braking performance of these series products is also represented on Belt transport vehicles.
●The YW-E series brake is two-step braking device. In the first braking step, a minor torque (adjustable with the prescribed limits)is exerted to make stable deceleration braking. When body stops, the second step starts. A bigger torque (adjustable with the prescribed limits) is exerted to realize reliable maintenance or storm braking. The interval time between the two steps staring can be adjusted by damping single way throttle in cylinder circuit (with 1-15 seconds ).

主要特點MAIN FEATURE



●制動襯墊為卡裝式整體成型結構,更換十分方便、快捷。
●聯鎖式退距均等裝置,使用中始終保持兩側瓦塊退距均等,避免退距不均使一側制動襯墊浮貼制動輪的現象。
●主要擺動鉸點均沒有自潤滑軸承,傳動效率高,壽命長,使用過程中無需潤滑。
●采用Ed系列推動器配套,動作靈敏,壽命長。
●常閉式設計,(斷電)彈簧制動,(通電)推動器釋放。
MAIN FEATURE
●Brake lining is of clamped integral forming structure, which is easy and quick to replace.
●Interlocking shoe clearance balancing device and shoe auto- aligning device constantly equalize the clearance of brake shoes on both sides and make adjustment unnecessary, completely avoiding brake lining one side sticking to brake wheel.
●Main hinge points are equipped with sef-lubricating bearing, making high ficiency of transmission, long service ife.
Lubricating is unnecessary during operation.
●The Ed series thrusters are characterized by flexible action and long operating ife.
●Brake closes in case of power failure (F ail- Safe Principle). Braking by spring power. Lifing by thruster.
