■ Overview
Theelectric chassis truck adds electric operation function to the original manual operation chassis truck. The overall size is the same as the original standard manual chassis truck. It provides the necessary hardware foundation for realizing the requirements of intelligent, programmed, remote control of the switch cabinet. After years of improvement and innovation,electric chassis trucks have developed from the 1st generation heightened type to the current 3rd generation integrated type. Starting from 3rd generation, professionally designed miniature permanent magnet DC motors have been adopted to make full use of the excess space of the original chassis. After installation, will not change the height, external installation dimensions, interlocking function, etc. of the original manually operated chassis truck, with simple structure and strong versatility.
■ Type description
■ Electric chassis truck (manual priority) S
The electric chassis truck (manual priority) is to add the manual priority function based on the original electric chassis truck. The chassis truck adds a microswitch, which is associated with the crank handle operation hole. When the chassis truck has a manual priority function, plug in the crank handle, and the controller buttons will not be able to be operated (see the module control circuit for details). When additional installation is required, add S to the original electric chassis truck DPC-□/DD3, as DPC-□/DD3S.
■ Electric chassis truck (gear type, patented product) DPC-mouth-mouth/DD5
This chassis truck is a new type of electric chassis truck with a gear transmission structure and a motor-integrated design. The chassis truck with a simple and beautiful appearance; the transmission box structure is reduced, and the space of the electric part is smaller; it is more conducive to quality control, integrated and single-component control of the motor.
Structural advantages:
1. Electric and manual switching of clutch tripping is easier;
2. The overall dimensions of the chassis truck are the same as the manual chassis truck, no need to modify the frame.

When operating the handcart, it is necessary to meet the circuit breaker interlocking conditions and the standby interlocking conditions, and the earth switch must be in the opening position; when operating the earth switch, the interlock signal input conditions must be met, and the spare interlocking conditions of the handcart part must be met at the same time.In addition: Local / remote, remote reset input are also applicable to the earth switch part.
