本系列施工升降机传动机构置于吊笼顶部，使升降机运行、起动平稳、噪音低，维修方便，齿轮、齿条咬合准确平稳，使用寿命长。

　　特 点：

　　本系列施工升降机传动机构置于吊笼顶部，使升降机运行、起动平稳、噪音低，维修方便，齿轮、齿条咬合准确平稳，使用寿命长。

　　传动装置采用两套YZEJ.A132M-4型高性能电动机，每套装置各自独立，分双电机、双减速机和三电机三减速机两种型式，每台电机均装有直流电磁制动器、且制动磨擦付具有自动跟踪、调整制动间隙功能，制动平稳可*，减速机为平面二次包洛环面蜗轮蜗杆减速机，结构紧凑，效率高、承载能力大、寿命长等优点。

　　安全装置完善齐全可*，确保升降机安全施工运行。

　　本升降机吊笼分操作室和不带操作室(底笼相应变动)、电缆系统分为电缆滑车式(独立道轨式及借助塔身道轨架为道轨式)和自落卷绕式三种形式，附着架分为直接附着和带后排管的附着架两种形式，供用户选择。

　　变频调速施工升降机有如下特点：启、制动平稳，无冲击;升降速度可调;启动电流小于额定电流;机械磨损下降明显;能源节约效果显著。

　　CHARACTERS：

　　The series construction hoist´s transmission mechanism is on the top of the cage and so that it makes the hoist´s operation and starting more stationary and low-noise, convenient maintenance, accurate and stationary engagement of gear and rack, long service life.

　　Two set of Model YZEJ.A132M-4 high-performance electric motors are applied in the transmission devices. Each devices is independent of each other. They have two types: A) double-motor and double-reduction gear; B) three-motor and three-reduction gear, Each motor is equipped with direct current electromagnetic brake friction couple has the function of automatically tracking braking-gap and its braking is stationary and reliable, the reduction gear is of worm and worm wheel with planar quadratic ring envelopes and it has advantage of compactness, high-efficiency large-bearing capacity, durability and soon.

　　Safety devices are perfect and reliable to ensure the hoists safe operation.

　　There are three type of hoisting cage (with driving cap or not), three type of cable system(cable trolley with independent rail, cable trolley whose rail is rail frame itself and auto winding roller), two type of anchorage frame(directly anchorage frame with back pipes) for selecting.

　　Frequency conversion building hoist has such traits: Starting and braking are steady with no pounding. The lifting speed can be controlled. Starting current is lower than rated current. The mechanical wear and tear is reduced evidently. Power saves efficiently.
