Advantages of 45T Lead-acid Battery Locomotive
-
High self-made ratio: Shaoli has a self-made ratio of products exceeding 90%. For the 45T lead-acid battery locomotive, key components like motors and lead-acid batteries are produced in-house. This ensures better quality control and cost-effectiveness.
-
Advanced speed regulation: It is equipped with an electronic speed controller with high reliability, which enables continuous and stepless speed regulation, allowing for precise control during operation.
-
Reliable braking system: Adopts a mechanical drum brake to the coupler, providing stable and reliable braking performance, which is crucial for safety in subway and tunnel shield construction.
-
Adaptability to harsh environments: Designed for subway and tunnel shield construction, it can withstand harsh construction environments such as poor track conditions, steep slopes, and high humidity.
