The Stertil-Koni ST4175 is a 17,500 kg heavy-vehicle platform hoist for workshops that want full-length under-vehicle access without a pit or a crossbeam spanning the working area. The platforms lift vertically and the clear centre lets technicians move beneath trucks and buses with fewer floor-level obstructions. Platform lengths from 6 to 11.5 metres allow the lift to be configured around different fleet lengths. A 230 mm drive-on height suits many buses and lower-clearance heavy vehicles, while the eBright control platform manages synchronisation, operating information and service diagnostics. The ST4175 is a project-installed lift rather than a generic off-the-shelf bay. Platform length, spacing, ramp arrangement, installation type, foundation, jacking beams and workshop services should all be resolved as part of site planning.
