1、限速器为了防止固定升降机http://www.rgsjpt.com/的吊笼超速或坠落而设置的一种安全装置，分为单向式和双向式两种，单向限速器只能沿吊笼下降方向起限速作用，双向限速器则可沿吊笼的上下两个方向起限速作用，限速器应按规定期限进行性能检测。
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、固定升降机上、下限位器为防止吊笼上、下时超过需停位置，或因司机误操作以及电气故障等原因继续上行或下降引发事故而设置的装置，安装在吊笼和导轨架上，限位装置由限位碰块和限位开关构成，设在吊笼顶部的最高限位装置，可防止冒顶；设在吊笼底部的最低限位装置，可准确停层，属于自动复位型。
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、安全钩是为防止固定升降机吊笼达到预先设定位置，上限位器和上极限限位器因各种原因不能及时动作，吊笼继续向上运行，将导致吊笼冲击导轨架顶部面发生倾翻坠落事故而设置的钩块状，也是最后一道安全装置。它能使吊笼上行到轨架安全防护设施顶部时，安全地沟在导轨架上，防止吊笼出轨，保证吊笼不发生倾覆坠落事故。
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、通讯装置由于司机的操作室位于吊笼内，无法知道各楼层的需求情况和分辨不清哪个楼层发出信号，因此固定升降机必须安装一个闭路的双向电器通讯装置，司机应能听到每一楼层的需求信号。
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、固定升降机http://www.rgsjpt.com/断绳保护装置吊笼和配重的钢丝绳发生断绳时，断绳保护开关切断控制电路，制动器抱闸停车。
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.
