The new operator's cab of the Plasser AssemblyLiner 1020 is easily accessible via access steps and a safety platform.
The room height of the new cab is 2.2 metres. The operating station on the right offers a direct view of the laying unit. Thanks to Plasser WorkView, the one on the left offers optimum visibility of work units where it is not possible to integrate an ergonomically designed cab.
Track-bound assembly-line methods have been making a significant contribution to occupational safety in track maintenance since the end of the 1960s. It became possible to mechanize and automate hard manual labour.
New milestones in ergonomics and occupational safety for large machines: the development of the new Plasser AssemblyLiner 1020 is setting standards.
Handling all of the material logistics within the track under construction is one of the major advantages of track-bound assembly-line methods. The technology saves on adjacent-track closures and increases the sustainability of large construction sites. A prerequisite for assembly design is the intelligent use of the existing machine cross-section, which is limited by the structure gauge. In the past, these conditions left the operating staff with very little space in some work cabs. With the new AssemblyLiner, the operating concept has been completely redesigned.
Today, high-resolution cameras make it possible to keep the operator farther away from the place where the machine is in action and to move them to a place where it is possible to integrate an ergonomic workstation with more space, sufficient height, and fewer stress factors. In addition, optimized access points when entering and leaving the cab increase occupational safety. 14 cameras provide razor-sharp images of the working areas, which are transmitted to the air-conditioned cab at the front section of the machine via five monitors. Plasser WorkView offers the possibility of creating equivalent or even better visibility conditions than a cab directly next to the work unit would offer.
The camera image exactly shows the relevant sections. Split-screen monitors make it possible to combine several viewing angles. Depending on the work configuration, the operator is given a different selection of cameras, tailored to the view for steering the crawler running gear, the view of the track with automatic switching of the direction of travel, the sleeper pick-up unit, and several views of the excavating chain. Additional camera images provide a view of the old-sleeper collection system, the plough blade with a screw conveyor for creating an optimum sleeper bed, and the sleepers being laid.
In the past, workspaces in narrow cabs, such as those used when removing old sleepers, were often difficult to access. They were small, sometimes poorly ventilated depending on the weather conditions, and not very attractive. The new operating concept with Plasser WorkView provides an appealing working environment. Another helpful feature is the indicator line that appears when it is the ideal time to pick up the old sleepers.
