1、限速器為了防止固定升降機http://www.qdysj.net/的吊籠超速或墜落而設置的一種安全裝置，分為單向式和雙向式兩種，單向限速器只能沿吊籠下降方向起限速作用，雙向限速器則可沿吊籠的上下兩個方向起限速作用，限速器應按規(guī)定期限進行性能檢測。
The governor in order to prevent speeding or falling cage and set up a safety device fixed lifts into one-way and two-way two-way along hoists the governor can only rate-limiting role in the lowering direction, two-way the governor can

be up and down in both directions along hoists rate-limiting, the governor should be required to conduct performance testing period.

2、固定升降機上、下限位器為防止吊籠上、下時超過需停位置，或因司機誤操作以及電氣故障等原因繼續(xù)上行或下降引發(fā)事故而設置的裝置，安裝在吊籠和導軌架上，限位裝置由限位碰塊和限位開關構(gòu)成，設在吊籠頂部的最高限位裝置，可防止冒頂；設在吊籠底部的最低限位裝置，可準確停層，屬于自動復位型。
Fixed lifts, the lower limit is to prevent the cage, over the need to stop at the next location, or because of an electrical fault driver misuse and other reasons to go up or down and set the device to cause the accident, and installed in the cage and rack rails, limit device by limiting touch block and limit switch, located in the cage at the top of the highest limit device to prevent roof collapse; minimum bit device in the bottom of the cage, can accurately stop layer, is automatically reset type.

3、安全鉤是為防止固定升降機吊籠達到預先設定位置，上限位器和上極限限位器因各種原因不能及時動作，吊籠繼續(xù)向上運行，將導致吊籠沖擊導軌架頂部面發(fā)生傾翻墜落事故而設置的鉤塊狀，也是最后一道安全裝置。它能使吊籠上行到軌架安全防護設施頂部時，安全地溝在導軌架上，防止吊籠出軌，保證吊籠不發(fā)生傾覆墜落事故。
Safety hook is fixed to prevent the lift cage reaches the preset position, the upper limit and upper limit stopper for various reasons can not be timely action continues to run up the cage, the cage will cause the top surface of the

impact of rail rack tipping fall accident while setting the hook block, also the last one safety device. When it is up to the top of the cage to make the rail safety facilities, security trench in rack rails to prevent derailment hoists, hoists ensure overturning fall accident does not occur.

4、通訊裝置由于司機的操作室位于吊籠內(nèi)，無法知道各樓層的需求情況和分辨不清哪個樓層發(fā)出信號，因此固定升降機必須安裝一個閉路的雙向電器通訊裝置，司機應能聽到每一樓層的需求信號。
Because of the communication device driver operating room located inside the cage, unable to know the needs and circumstances of each floor floor signaled a confusion which, it must be installed in a fixed lift two-way closed-circuit

electrical communication device, the driver should be able to hear each floor demand signal.

5、固定升降機http://www.qdysj.net/斷繩保護裝置吊籠和配重的鋼絲繩發(fā)生斷繩時，斷繩保護開關切斷控制電路，制動器抱閘停車。
Lift-off protection device fixed rope hoists and wire rope counterweight rope breakage occurs, the broken rope protection switch off control circuit, brake parking brake.
