Height-Adjustable Access Platforms for Bus Roof and Window Maintenance
This article first appeared in the Bus-News magazine, Issue 2 2022.
Pfaff Verkehrstechnik is increasingly supplying its recently launched access platforms for bus roof maintenance to municipal bus operators throughout Europe, for example, as far away as Norrköping, a Swedish city in the province of Östergötland.
The roof-working platforms recently installed there are used to carry out maintenance and repair work safely and efficiently on the roofs and windows of the municipal bus operator’s vehicles. Pfaff Verkehrstechnik has already delivered several such systems to Swedish companies as Sweden is one of the pioneers in electromobility, and the electrically powered buses frequently used there require more maintenance than diesel-powered buses.
In principle, Pfaff Verkehrstechnik can flexibly adapt its newly designed access platforms to any bus fleet thanks to different segment lengths based on the modular principle, regardless of whether they are simple 12m buses, double-decker buses or 18m articulated buses. The bus company in Norrköping now uses two connected, individually extendable access platforms, each 9.6m long, on three lifting jacks on each side of the vehicle for maintenance on both sides of the bus. This ensures that for an overall vehicle length of almost 20m, there is a continuously accessible walkway at the height of the windows all the way up to the roof of the vehicle. Workers can move freely and safely over the entire walkway width of 755mm.
Convenient Access via Stairs with Secured Gate
The platform combinations can be adjusted in height as required. For this purpose, three stationary lifting jacks are firmly mounted on each side on the workshop floor. This structure supports the two working platforms with two electrically driven extension modules, which extend 500mm within 40 seconds and thus connect seamlessly to the bus.
