结构特点
Structural features
1、启闭机包括电机、启闭机、机架、防护罩等组成;采用三级减速方式，用螺旋副传动，输出转距更大。启闭机配套钢架克服土建不平整，以减少整机噪声及振动。
1. The hoist consists of motor, hoist, frame, protective cover, etc; It adopts three-stage deceleration mode and screw pair transmission, with larger output torque. The supporting steel frame of the hoist overcomes the unevenness of civil engineering to reduce the noise and vibration of the whole machine.
2、采用户外型长时工作制电机，防护等级≥IP55。行程控制机构采用十进制计数器原理，控制行程的误差0.5%。转距保护控制是通过蜗杆产生轴向位移触动微动开关，来达到保护电器的原理。
2. Outdoor long-time working motor is adopted, with protection grade ≥ IP55. The travel control mechanism adopts the principle of decimal counter, and the error of control travel is 0.5%. The principle of torque protection control is to protect the electrical appliance by touching the microswitch through the axial displacement of the worm.
3、操作维护简便，可实现现场和远控操作。
3. It is easy to operate and maintain, and can realize on-site and remote control operation.
