| 结构特点 Structural characteristics 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，用螺旋付传动，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 and so on. It adopts three-stage deceleration mode, drives with screw-drive, and has larger output distance. The supporting steel frame of hoist can overcome the unevenness of civil construction, so as 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-term working motor with protection grade (> IP55). The principle of decimal counter is adopted in the stroke control mechanism, and the error of the control stroke is 0.5%. Rotation distance protection control achieves the principle of protecting electrical appliances by the micro-switch triggered by the axial displacement produced by 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. |
