Advantages: The rail-type hydraulic drainage and cable trough trolley adopts an integrated steel mold design, featuring high mold strength and stability, preventing "mold shifting" during construction. Attached vibrators are installed on the steel mold, with vibration time controlled numerically, ensuring vibration effectiveness and avoiding issues such as honeycombing and sand flow.

Using the rail-type hydraulic drainage and cable trough trolley for construction, once the trolley is assembled, only the rails need to be installed for each construction operation. After the trolley is positioned, fully automatic operations are performed for mold positioning, eliminating the need for mold assembly and disassembly. Construction is fast, with each cycle completed in one day.
