The Track Inspection Cart introduced here is a 0.5-ton bidirectional model custom-designed for a Taiwanese client. The client's purpose was very clear-to use the equipment for high-speed rail track inspection and maintenance projects.
This Taiwanese client is responsible for track maintenance work on high-speed rail projects and required a dedicated inspection cart for daily inspection and maintenance tasks. They proactively contacted us to seek a suitable solution.
The entire communication process lasted approximately one month. Initially, based on the client's preliminary requirements, we proposed a unidirectional Track Inspection Cart. However, after in-depth discussions, we gained a clearer understanding of the client's actual operating conditions and realized that a unidirectional design would not be suitable.
After identifying this issue, we promptly adjusted the solution, upgrading the original unidirectional driving mode to a bidirectional design. This eliminated the need to manually turn the cart around on the track and perfectly matched the client's high-speed rail inspection requirements.
During further communication, we learned that the client's high-speed rail line included a 4‰ (four-per-mille) gradient, which became a critical technical challenge. On such gradients, standard steel wheels used on conventional inspection carts are prone to slipping, creating a serious safety risk.
To address this issue, we revised the design and replaced the standard wheels with rubber-coated wheels. These wheels significantly increase friction, effectively preventing slippage on gradients and ensuring safe operation.
Based on the client's daily inspection schedule, the cart was equipped with a 150Ah lithium battery, allowing it to operate continuously for two full working days without frequent charging interruptions.
Throughout the entire cooperation process, we prepared all technical documents in detail and responded promptly and patiently to every question raised by the client. By actively cooperating and addressing all requirements, we earned the client's full trust. Ultimately, the client decided to purchase two units for trial operation.
These two DGT series Track Inspection Carts have now been successfully delivered and are currently in use for high-speed rail inspection and maintenance. The client has expressed high satisfaction with the equipment's suitability, stability, and our overall service quality.

Benefits for the Buyer in This Project
First, customized design eliminates adjustment costs.
Based on the client's actual needs, we upgraded the cart from a unidirectional to a bidirectional configuration, eliminating the need for post-delivery modifications. The design was also adapted to the 4‰ gradient of the high-speed rail track, removing the need for additional anti-slip devices and saving on extra equipment investment.
Second, rubber-coated wheels improve safety and reduce maintenance costs.
The rubber-coated wheels prevent slipping on slopes, protecting the safety of maintenance personnel and reducing the risk of equipment damage. At the same time, they minimize wear on the rail surface, helping lower long-term maintenance costs for the high-speed rail infrastructure.
Third, long battery life improves efficiency.
The 150Ah lithium battery supports two days of continuous operation, eliminating frequent charging and saving approximately 1–2 hours per day. This enables uninterrupted maintenance work and reduces the need for dedicated personnel to manage charging or battery replacement, indirectly lowering labor costs.
Fourth, attentive service ensures smooth project execution.
We actively cooperated with the client throughout the project, providing comprehensive documentation and fast responses. This reduced repetitive communication and document revisions, significantly shortening the overall project timeline.
As with this Taiwanese client, the entire process-from initial communication to final delivery-was smooth, and the equipment was delivered on time without affecting the high-speed rail maintenance schedule. This avoided potential risks and losses associated with delayed delivery.
Fifth, precise functional matching improves inspection quality.
This Track Inspection Cart fully meets the operational requirements of high-speed rail inspection, enabling efficient maintenance work and contributing to improved safety and operational stability of the rail system.
