ONVALLA designs, builds, installs and maintains gantry and semi-gantry cranes, single-girder 1–20 t and double-girder 2–500 t, for factories, ports, yards and construction.
An underslung crane hangs from the building structure with no extra columns and more lifting height; ONVALLA’s electric overhead side crane extends outside to lift loads in.
With more than 30 years of crane manufacturing, ONVALLA developed an Installation Cart built to the customer’s requirements, extending its production capability.
ONVALLA designs cranes for safety and quality, and engineers special tools and equipment that work with the crane, plus material-handling consulting for correct use.
ONVALLA and AMR Asia co-designed Power Rail installation vehicles for Thailand’s first straddle monorail lines, the MRT Pink and Yellow Lines. ONVALLA built and tested 8 sets.
