Answer:
The trailer features a motorized mast or hydraulic jacking arrangement providing a height adjustment span of 2.2 m to 3.0 m from the ground to the display top edge, along with 330° horizontal display rotation and locking. Chassis stability is maintained using 4-point height-adjustable jacks and a collapsible jockey wheel.
The mobile trailer assembly of the Ador SERENITi (KTI04015002ASWT) incorporates heavy-duty mechanical arrangements designed for rapid highway deployment and wind resistance:
- Display Hoisting Mechanism: Equipped with a motorized mast or hydraulic jacking system that adjusts sign height from 2.2 meters to 3.0 meters (measured from ground level to the top edge of the display casing).
- Rotational Orientation: The display assembly supports 330° continuous horizontal rotation with an integrated mechanical lock to align precisely with traffic approaching around road curves.
- Solar Array Mounting: The solar PV panel is fixed directly onto the mast structure above the radar speed sign for unobstructed sun exposure.
- Site Stabilization: The steel chassis uses a 4-point height-adjustable outrigger jack setup to ensure firm, level footing on rough shoulders, alongside a tow bar with a foldable, height-adjustable jockey wheel.
- Switchgear Housing: Includes an onboard IP55-rated junction box fabricated from M.S. CRCA sheet to house solar regulators, battery chargers, and electrical switchgear. Note that operational batteries (they are not included) must be sourced separately.
