Hydraulic Mast System
Industrial-grade hydraulic cylinder provides smooth elevation to clear roadside obstacles.
C-Tra-VMS Solar Trailer
Ventilated traffic display for high-wind gantries and toll bridges.
Tra-Vent combines Chipshow’s highway VMS technology with a ventilated mesh design. Engineered for toll plazas and cross-sea bridges, its hollow structure reduces wind load and cabinet weight (approx. 27–30 kg/m²), helping designers safely deploy LED signs on aging gantries and high-risk coastal structures with less reinforcement than traditional box-type VMS.
